Heating Old Houses
“When these homes were built, they didn’t think about saving energy. They didn’t care — they just let it run wild and the house was in great shape because it could breathe really well. But unfortunately we’re in a situation now where we want to tighten up our buildings. There’s absolutely no reason why these houses can’t be efficient.
“There are lots of things you can do. For example, what costs you money 24 hours a day, seven days a week, even if you’re on vacation? Your hot-water heater. It maintains a temperature so that when you take a shower at the end of a long day, you can just turn that faucet on and you’ll have your hot water.
“But if you insulate the outside of the tank, you’re increasing the efficiency of the heater by lessening the amount of time it needs to come on to keep that water hot.”
