With some low temperatures already experienced and more expected this winter, we thought we’d address some common cold-weather questions today.
Q. Can my pipes freeze when the temperature is at or below 32 degrees?
A. Yes. There’s never a bad time to insulate pipes. It’s fairly inexpensive and can help save money in energy costs. This and air sealing all penetrations with foam are also standard PUD weatherization measures.
However, what you’re probably really asking is “What can I do right now to prevent my pipes from freezing?” In extended cold spells one way to prevent a bursting pipe is to leave both hot and cold water dripping, preferably at the sink farthest from the hot water tank. This will help circulate the entire water system.
This may cost a little money in water and energy loss, but it will be a lot cheaper than replacing broken pipes and fixing water damage.
Also, if you haven’t done so yet, unhook your garden hoses and wrap your outside faucets. It doesn’t have to be fancy — an old T-shirt or towel, even newspaper covered with plastic bags and rubber bands will do the trick.
Q. When it’s cold, we often use alternative methods to help heat our house. Is there anything we should know about this?
A. Yes — WITH EXTREME CAUTION. There are many dangers lurking when using certain alternative sources of heat. Carbon monoxide poisoning is the real risk and it too often occurs when people are using a gasoline-powered generator to produce electricity to run heaters and lights. Make sure that it is not operating inside the home or garage and is well ventilated so the fumes cannot get into even the attic vents under the eaves. If the generator isn’t far enough away from the house, the exhaust — which is odorless and colorless — can seep into your home and make you sick before you realize what is happening! It can definitely cause unnecessary death.
In fact, as you may have seen in the newspaper (including this column) or heard on the radio, carbon monoxide poisoning is such a concern that a new state law now has much stricter requirements for having carbon monoxide detectors for rental properties. If you have any type of fuel burning heat source or generator, you should consider the safety aspect of a carbon monoxide detector for your home!
Other risks include using an open oven or a stove top to heat a room. They can overheat and cause a fire. The use of a propane grill or briquette-type barbecue inside of a structure is definitely a carbon monoxide poisoning risk.
Also, be cautious when plugging in electric heaters. They draw a lot of power and can easily overwhelm an undersized extension cord. If the cord feels at all warm it is a potential fire hazard. The house may catch fire before a circuit breaker shuts off the power! If the breaker or fuse does trip, you have too much energy in that line and this is also a very dangerous fire hazard. Start unplugging other uses on the same circuit. Be safe!
Q. Are there other ways to keep the cold out, and the heat in?
A. One of the best ways to stay warm during the winter months is to make sure your house is properly “weatherized.”
Weatherizing, generally, means to properly weather-strip, insulate and air seal floors, walls, ceiling, attics, doors and windows. Using industry and code standards will keep your house comfortable and energy efficient with the least amount of influence from the outside temperature. The savings will often pay for the cost over just a couple of years.
Properly installed weatherization measures can stop both cold air from getting into the home and heated air from escaping.
If you are electrically heated, call the nice folks at the PUD Conservation for a free energy inspection. They will recommend the best insulation measures for your house and you may also be eligible for a substantial rebate when you insulate to the PUD standard.
If your house needs to be insulated, but you need a loan to get that done, we work closely with the PUD weatherization program and make tailored loans to income- and credit- qualified homeowners.
However, if you want to do something today to help you feel warmer, add layers of clothing to create immediate results. Then start checking your windows, doors, outlets, attic hatch and any other areas for drafts and plug them as best you can. (And don’t forget to close the fireplace draft, after checking for live embers, if you’re not using the fireplace!)
Q. Can I close my foundation vents to prevent heat loss?
A. Yes. Are you surprised? We’re strong advocates of ventilating your house to keep moisture at bay. However, we do recommend closing your foundation vents as long as the temperature remains below freezing. It will keep the house more comfortable and maybe save on your heating bill. (Just make sure to open them up again when the weather gets a bit warmer!)
