Winterizing your Cape Cod home

By Christopher Solomon of MSN Real Estate

So you've pulled your sweaters out of mothballs and found your mittens at the bottom of the coat closet. But what about your house -- is it prepared for the cold months ahead?



You'll be a lot less comfortable in the coming months if you haven't girded Home Sweet Home for Old Man Winter.



With the help of several experts, we've boiled down your autumn to-do list to 10 easy tips:



1. Clean those gutters

Once the leaves fall, remove them and other debris from your home's gutters -- by hand, by scraper or spatula, and finally by a good hose rinse -- so that winter's rain and melting snow can drain. Clogged drains can form ice dams, in which water backs up, freezes and causes water to seep into the house, the Insurance Information Institute says.

As you're hosing out your gutters, look for leaks and misaligned pipes. Also, make sure the downspouts are carrying water away from the house's foundation, where it could cause flooding or other water damage.



"The rule of thumb is that water should be at least 10 feet away from the house," says Michael Broili, the director of the Well Home Program for the Phinney Neighborhood Association, a nationally recognized neighborhood group in Seattle.



2. Block those leaks

One of the best ways to winterize your home is to simply block obvious leaks around your house, both inside and out, experts say. The average American home has leaks that amount to a nine-square-foot hole in the wall, according to EarthWorks Group.



Professional Services

Find local plumbers, electricians, contractors and more.



Select a categoryAdditions/RemodelingAir ConditioningArchitects/EngineersCleaning/Maid ServicesConcreteDecksDesigners/DecoratorsElectricalFencesFlooring/CarpetGarage/Garage DoorsLandscapingNew Home BuildersPaintingPlumbingRoofingSheds/EnclosuresSidingTileWindowsFirst, find the leaks: On a breezy day, walk around inside holding a lit incense stick to the most common drafty areas: recessed lighting, window and door frames, electrical outlets.



Then, buy door sweeps to close spaces under exterior doors, and caulk or apply tacky rope caulk to those drafty spots, says Danny Lipford, host of the nationally syndicated TV show "Today's Homeowner." Outlet gaskets can easily be installed in electrical outlets that share a home's outer walls, where cold air often enters.



Outside, seal leaks with weather-resistant caulk. For brick areas, use masonry sealer, which will better stand up to freezing and thawing. "Even if it's a small crack, it's worth sealing up," Lipford says. "It also discourages any insects from entering your home."



3. Insulate yourself

"Another thing that does cost a little money -- but boy, you do get the money back quick -- is adding insulation to the existing insulation in the attic," says Lipford. "Regardless of the climate conditions you live in, in the (U.S.) you need a minimum of 12 inches of insulation in your attic."



Don't clutter your brain with R-values or measuring tape, though. Here's Lipford's rule of thumb on whether you need to add insulation: "If you go into the attic and you can see the ceiling joists you know you don't have enough, because a ceiling joist is at most 10 or 11 inches."



A related tip: If you're layering insulation atop other insulation, don't use the kind that has "kraft face" finish (i.e., a paper backing). It acts as a vapor barrier, Lipford explains, and therefore can cause moisture problems in the insulation.



4. Check the furnace

First, turn your furnace on now, to make sure it's even working, before the coldest weather descends. A strong, odd, short-lasting smell is natural when firing up the furnace in the autumn; simply open windows to dissipate it. But if the smell lasts a long time, shut down the furnace and call a professional.



It's a good idea to have furnaces cleaned and tuned annually. Costs will often run about $100-$125. An inspector should do the following, among other things:



Throughout the winter you should change the furnace filters regularly (check them monthly). A dirty filter impedes air flow, reduces efficiency and could even cause a fire in an extreme case. Toss out the dirty fiberglass filters; reusable electrostatic or electronic filters can be washed.



5. Get your ducts in a row

According to the U.S. Department of Energy, a home with central heating can lose up to 60% of its heated air before that air reaches the vents if ductwork is not well-connected and insulated, or if it must travel through unheated spaces. That's a huge amount of wasted money, not to mention a chilly house. (Check out this audit tool for other ideas on how to save on your energy bills this winter.)



What's your home worth?

Ducts aren't always easy to see, but you can often find them exposed in the attic, the basement and crawlspaces. Repair places where pipes are pinched, which impedes flow of heated air to the house, and fix gaps with a metal-backed tape (duct tape actually doesn't stand up to the job over time).



Ducts also should be vacuumed once every few years, to clean out the abundant dust, animal hair and other gunk that can gather in them and cause respiratory problems.



6. Face your windows

Now, of course, is the time to take down the window screens and put up storm windows, which provide an extra layer of protection and warmth for the home. Storm windows are particularly helpful if you have old, single-pane glass windows. But if you don't have storm windows, and your windows are leaky or drafty, "They need to be updated to a more efficient window," says Lipford.



Of course, windows are pricey. Budget to replace them a few at a time, and in the meantime, buy a window insulator kit, Lipford and Broili recommend. Basically, the kit is plastic sheeting that's affixed to a window’s interior with double-stick tape. A hair dryer is then used to shrink-wrap the sheeting onto the window. (It can be removed in the spring.) "It's temporary and it's not pretty, but it's inexpensive (about $4 a window) and it's extremely effective," says Lipford.



7. Don't forget the chimney

Ideally, spring is the time to think about your chimney, because "chimney sweeps are going crazy right now, as you might have guessed," says Ashley Eldridge, director of education for the Chimney Safety Institute of America.



That said, don't put off your chimney needs before using your fireplace, Eldridge advises. "A common myth is that a chimney needs to be swept every year," says Eldridge. Not true. But a chimney should at least be inspected before use each year, he adds. "I've seen tennis balls and ducks in chimneys," he says.



Ask for a Level 1 inspection, in which the professional examines the readily accessible portions of the chimney, Eldridge says. "Most certified chimney sweeps include a Level 1 service with a sweep," he adds.



Woodstoves are a different beast, however, cautions Eldridge. They should be swept more than once a year. A general rule of thumb is that a cleaning should be performed for every ¼ inch of creosote, "anywhere that it's found." Why? "If it's ash, then it's primarily lye -- the same stuff that was once used to make soap, and it's very acidic." It can cause mortar and the metal damper to rot, Eldridge says.



Another tip: Buy a protective cap for your chimney, with a screen, advises Eldridge. "It's probably the single easiest protection" because it keeps out foreign objects (birds, tennis balls) as well as rain that can mix with the ash and eat away at the fireplace's walls. He advises buying based on durability, not appearance.



One other reminder: To keep out cold air, fireplace owners should keep their chimney's damper closed when the fireplace isn't in use. And for the same reason, woodstove owners should have glass doors on their stoves, and keep them closed when the stove isn't in use.



Check out CSIA'S Web site for a list of certified chimney sweeps in your area.



8. Reverse that fan

"Reversing your ceiling fan is a small tip that people don't often think of," says Lipford. By reversing its direction from the summer operation, the fan will push warm air downward and force it to recirculate, keeping you more comfortable. (Here's how you know the fan is ready for winter: As you look up, the blades should be turning clockwise, says Lipford.)



9. Wrap those pipes

A burst pipe caused by a winter freeze is a nightmare. Prevent it before Jack Frost sets his grip: Before freezing nights hit, make certain that the water to your hose bibs is shut off inside your house (via a turnoff valve), and that the lines are drained, says Broili. In climes such as Portland, Ore., or Seattle, where freezing nights aren't commonplace, you can install Styrofoam cups with a screw attachment to help insulate spigots, says Broili.



Next, go looking for other pipes that aren't insulated, or that pass through unheated spaces -- pipes that run through crawlspaces, basements or garages. Wrap them with pre-molded foam rubber sleeves or fiberglass insulation, available at hardware stores. If you're really worried about a pipe freezing, you can first wrap it with heating tape, which is basically an electrical cord that emits heat.



10. Finally, check those alarms

This is a great time to check the operation -- and change the batteries -- on your home's smoke detectors. Detectors should be replaced every 10 years, fire officials say. Test them -- older ones in particular -- with a small bit of actual smoke, and not just by pressing the "test" button. Check to see that your fire extinguisher is still where it should be, and still works.



Also, invest in a carbon-monoxide detector; every home should have at least one.

Upgrading an Old Fuse Type Electric Panel, REPRINT BY Steven Soby

Changing out your fuse panel to a circuit breaker Banel

It should be noted that in most jurisdictions it is necessary to obtain an electrical permit in order to convert from a fuse panel to a circuit breaker panel. Usually this type of permit is only granted to licensed electrical contractors. Failure to do so can lead to fines and utilities disconnecting power to your home.


Electrical distribution fuse panels, as shown in Figure 2 have become obsolete and in many jurisdictions a homeowner cannot get home insurance if they have a fuse panel installed.


Although a properly installed fuse panel is safe, insurance companies see the convenience to over size the fuse on a circuit as a potential hazard.

If you are converting from a fuse panel to a circuit breaker panel (as shown in Figure 1), because your home needs more power, then you must have the utility replace the incoming feed wires to your home. Just installing a new electrical distribution panel with more circuits will not provide your home with more power if the incoming service is not changed. The wires coming to your meter are sized based on the service provided. More power means larger gauge wires coming into your home.



The basic electrical service coming into your home will look something similar to
If you have a fuse panel then the main disconnect will most likely have cartridge fuses installed, rated at the load acceptable for the home.


If you have sufficient power, and only want to change the current fuse panel to a circuit breaker panel, leaving the main disconnect as it is with the cartridge fuses, then the electrical parts that you require can be obtained at most of the big box home improvement stores, online, or at an electrical wholesale.


Make a list of the number and sizes of circuit breakers that you will require. The breaker size is based on the gauge of the wire that is being used to run from the distribution panel to the device or appliance.



Do not assume that the screw-in fuse rating is correct for the wire size or circuit. People have a tendency to increase fuse amperage ratings as time progresses.



Charts on correct wire gauges for different amperes.



Purchase a panel that has more circuits spaces than you currently require so that you will have available spare breaker positions for future additions.



There should never be more than one wire on any fuse or breaker terminal. If there is more than one wire on a terminal count each wire as a separate circuit.



Remember that circuits in the fuse panel that fed 240 VAC to hot water tanks, ranges and clothes dryers were most likely made up of 2 cartridge fuses, as shown in Figure 1, on a removable fuse block. These will need to be replaced with double pole circuit breakers (see Table 1) for the proper amperage.

Table 1 - Types of Circuit Breakers

Single pole breaker is used for circuits that require 115VAC

Double pole breaker is used for circuits requiring 230 VAC or for spit receptacles (common in kitchens) where each of the sockets on a duplex receptacle are separately fused.

The cartridge fuse blocks serve 3 purposes:

1.They can be used to fuse each side of a 230 VAC circuit. Common for water heaters, ranges and dryers.

2.They can be used to fuse spit receptacles where the upper and lower part of the receptacle are on independent circuits. Common for kitchen receptacles.



3.They can be used as the main disconnect for the fuse panel. In this situation the cartridge fuses will disconnect all power from the fuse panel circuits.

You can purchase your new breaker electrical panel with and without a main breaker. This combines the older method of having a separate disconnect from the fuse panel. The main breaker turns off the power to all branch circuits. If you have a separate main disconnect switch, there is no need to have a main breaker.



You will be turning all of the power off in the home to do the conversion from the fuse panel to the circuit breaker panel. Because you will not have any utility lighting, make sure that you have flashlights or lanterns to provide you with working light.


1.Turn off the power at the main disconnect (see Figure 2). This is either a lever on the side of the main disconnect electrical box, usually market with "ON" in one direction and "OFF" in the opposite direction or a switch mounted on the front of the main disconnect electrical box, again marked "ON" and "OFF".

2.Open the main disconnect electrical box and remove the fuses. There is live power in this electrical box, even with the switch or lever turned to the "OFF" position. Removing the fuses, protects you from someone inadvertently turning the switch or lever back to the "ON" position and delivering power to the electrical circuits you are working on.

3.With the switch or lever in the "OFF" position and the fuses removed, the fuse distribution panel is dead. Remove the cover from the fuse distribution panel. You will most likely see a birds nest of wires running to terminals and grounding bars or screws.

The cables entering the fuse distribution box, should be coming in through box connectors. It is best to identify each of the cables and where it goes before you remove them. Use a piece of masking tape wrapped around the cable. Remove all the wires from terminals and pull the wires out through the box connectors (see Figure 2b).



The box connectors that you removed from the fuse panel can be reused on the new breaker panel.



4.It is most common that the wires running from the main disconnect electrical box to the fuse panel were run in a metal pipe, with threads on the ends, as shown in Figure 3. The pipe is most likely connected to the fuse panel using a large hexagon shaped nut, which screws over the thread on the inside of the fuse panel. There may also be a nut on the outside of the fuse panel, so that the fuse panel ends up being sandwiched between the nuts and the pipe goes through a knockout in the fuse panel. Remove the inside nut in the fuse panel from the pipe.





5.With the wires removed from all the terminals and the nut removed from the pipe, the only thing holding the fuse panel in position will be a few screws on the back of the fuse panel. Remove the screws and then remove the fuse panel from the wall.






6.Look at your breaker panel, there should be knockouts on the side, choose a knockout that is in the correct position and size to match the metal pipe holding the wires from the main disconnect. Remove the knockout.

The easiest way to remove the knockouts is to use a hammer, heavy duty flat head screw driver and a pair of lineman's pliers (see Figure 1). Place the edge of the screwdriver over the inside of the cut area of the knockout and hit it with the hammer, the knockout should bend inwards. Grab the piece that has bent in with the lineman's pliers and twist to break the tabs. On larger knockouts it may be necessary to use a small file to remove the burrs left by the knockouts on the panel.



7.Slide the wires from the main disconnect through the knockout hole - make sure you do not scratch or nick the insulation as the edges of the knockout can be sharp. Push the pipe through the knockout hole, slide the nut over the wires and tighten the nut.

8.Screw the panel to the wall using appropriate screws.

9.It is easier to dress, position, the wires if you start with the heaviest gauge wires first. These should be the wires coming from the main disconnect (see Table 1). It is highly likely that the wires will have to be cut to fit the layout of the new distribution panel. If the wires are to short - replace them. Although not an electrical requirement, a neatly dressed electrical box, is safer and will allow you to trace problems in the future.


10.The next step, after the wires have been connected from the main disconnect are the individual circuits. From a layout standpoint, mount the double pole breakers in the upper most slots and the 15 amp breakers in the slots below.

11.There should only be one circuit per breaker.

12.If a wire is to short to reach the location you can add to the wire inside the distribution panel using a wire nut or you can mount a junction box on the exterior of the panel and add to the cable length.

13.Not all breaker locations need to be used.

14.Bring the wires into the distribution panel by using the knockouts on the sides and bottom of the box. Use proper box connectors in the knockout holes to ensure that wire insulation is not damaged during installation.

15.Connect each of the breakers in sequence, placing the hot wire on the breaker, the neutral wire on the neutral buss bar and the ground wire to the grounding screws. Don't forget that in some cases, where you have a 240VAC appliance, the white wire may be used as a hot wire, not a neutral. Any white wires that are used as live wires should have black electrical tape wrapped over the white wire.

16.Once you have all the wires connected to the appropriate terminals, double check that they are all snug - pull on the wires individually and see if any of them move or pull out from the terminal.

17.The cover plate will have knockouts for each breaker. Only remove the knockouts that have breakers in those positions. Mount the cover plate on the box.

18.Replace the fuses in the main disconnect.

19.Turn the main disconnect lever or switch to the "ON" position.

Energy Management Systems Reprint By Stevn Soby, Electrician



Creating an Interactive Energy Management System

Air-conditioning units and heating systems are examples of power-hungry equipment that regularly switches on and off in commercial buildings. When these devices are all switched on at once, power consumption spikes, and a building's owners are left with hefty peak-demand charges on their electricity bills.





Smart switch: The controller shown here could improve the energy efficiency of building appliances. The devices communicate wirelessly and use swarming algorithms to collaboratively decide how to manage power usage.

Credit: REGEN Energy



A startup based in Toronto says that it has come up with a way to reduce energy use by mimicking the self-organizing behavior of bees. REGEN Energy has developed a wireless controller that connects to the control box on a piece of building equipment and functions as a smart power switch. Once several controllers have been activated, they detect each other using a networking standard called ZigBee and begin negotiating the best times to turn equipment on and off. The devices learn the power cycles of each appliance and reconfigure them to maximize collective efficiency.



The goal is to avoid everything coming on at the same time without sacrificing individual performance. The devices work through this problem using a "swarm algorithm" that coordinates activity without any single device issuing orders.



"Every node thinks for itself," says Mark Kerbel, cofounder and chief executive officer of REGEN Energy, which invented the proprietary algorithm embedded in each device. Before making a decision, he explains, a node will consider the circumstances of other nodes in its network. For example, if a refrigerator needs to cycle on to maintain a minimum temperature, a node connected to a fan or pump will stay off for an extra 15 minutes to keep power use below a certain threshold. "The devices must satisfy the local restraint but simultaneously satisfy the system objective," says Kerbel, adding that a typical building might have between 10 and 40 controllers working together in a single "hive." The devices are simple and quick to install and, because there's no human intervention, require no special training to use.



It's a dramatic departure from the top-down command model associated with current building-automation systems. Some researchers say that the decentralized approach to energy management offers a cheaper, more effective way to manage supply and demand in a delicately balanced electricity system. Indeed, some believe that it could be an early prescription for an emerging smart system.







"You're seeing a lot more interest in this on a modest scale," says David Chassin, a scientist at Pacific Northwest National Laboratory's energy-technology group, which is heading up the GridWise smart-grid initiative.



The benefits could extend beyond electricity savings for building owners. Today's electricity system is designed for peak consumption, which means that power plants are built to satisfy those few minutes of each day when power demand surges well above daily averages. By reducing peak demand on a large scale, utilities can maximize the operation of existing power plants while reducing the need to build new plants for occasional use. Another potential benefit is reduced carbon emissions, since power plants that supply peak electricity tend to be less efficient and fueled by coal and natural gas.







George Pappas, a professor of electrical and systems engineering at the University of Pennsylvania and an expert in distributed control systems, says that swarm logic is a natural fit for energy applications. "REGEN is ahead of the curve on this," says Pappas.



Operation within a building is one thing, but less certain is whether swarm logic can be trusted to manage the grid itself. Chassin says that the engineering community is understandably wary of decentralized or "emergent" control systems for the grid because, while they work remarkably well in certain applications, the approach is not well tested.



Kerbel first came up with the idea of using a swarm algorithm to manage power consumption in 2005. "We were politely told that this style of control just isn't ready and requires far more academic research," he says. "It's difficult to think outside the command-and-control box and allow this leap of faith--that is, relinquishing decision-making capabilities to individual nodes of the collective."



It's a bias that Herb Sinnock, manager of the Centennial Energy Institute, in Toronto, admits to having. He says that engineers typically want constant feedback so that they can measure system operation and make refinements. REGEN's technology dispenses with all that, but he notes that its application will allow for some mistakes. "It's not like they're positioning control rods in a nuclear reactor core. We're talking about affecting the temperature in a room by half a degree, so there's room for error," says Sinnock.



Sinnock's institute has been working with REGEN to evaluate the performance of its devices in the field. Tests have so far demonstrated that building owners--of hospitals, hotels, shopping malls, factories, and other large facilities--could save as much as 30 percent on their peak-demand charges. Those savings, REGEN claims, more than cover the cost of renting the devices, which is an option for major electricity consumers reluctant to buy the technology up front. If the devices are purchased, the payback is less than three years, says Kerbel.



The simplicity of the installation is what impresses Sinnock most. "In a few hours, they can have the devices installed and figuring out their environment and surroundings," he says. Pappas, meanwhile, says that he expects there will be much more interest in this type of application over the coming years, pointing to a U.S. economic stimulus package that calls for more investment in energy efficiency and smart-grid technologies. "A lot of the big impact and low-hanging fruit is going to come from using this approach," he says.
