When a water heater reaches a certain age, it can be easy to assume it’s living on borrowed time. It’s hard to say how long your water heater will last. Certified home inspectors estimate the life span to be about 10 years. Some manufacturers suggest 12 to 13 years, but it’s not unheard of for a water tank to last more than 40 years before the heating element finally gives out. That said, it’s wise to replace a water heater before it fails, because that failure can cause a lot of damage.
For most of us, heating and cooling accounts for the largest part of our household energy use. For someone wanting to replace a furnace system that runs on propane or fuel oil, an electric air-source heat pump could be a good alternative. A heat pump is also a cost-effective alternative to electric furnaces, baseboard heaters, and wall units.
Those who haven’t shopped for a new car in a while may be surprised to find the cost of new electric vehicles (EVs) is now comparable to that of gasoline-powered cars. With that in mind, it’s not so surprising that the EV market is growing rapidly. There’s lots more, however, that consumers should know about them in order to make an informed buying decision.
Many times, prospective homebuyers are so caught up examining other aspects of the houses they see, they don’t consider energy costs (such as electricity, gas, and propane) in their decision. They ought to, since the average home costs about $2,000 in energy expenses per year — that’s a lot of money over the life of the home.
The size of a home is one of the most important factors that will determine energy costs. As square footage increases, lighting requirements increase, and more importantly, the burden on heating and cooling equipment increases.
When Teresa Harshbarger and her family built their home outside of New Concord several years ago, they bought their water heater from Guernsey-Muskingum Electric Cooperative (GMEC). It came equipped with a radio-controlled switch that allows the cooperative to remotely turn off the heater to curtail electricity use during times of heavy demand. Though she says she’s sure the switch has been activated from time to time, she has never noticed when it happens.
Homeowners often fret about their older windows, perhaps even original to the house — maybe they let in cold drafts during the winter, or contribute to overheating in the summer. People like the look of the older windows, and replacing them with new ones is expensive. In last month’s column, we talked about replacing windows, but doing so is costly, and it could take 20 years of energy savings to recover the investment.
You can, however, make significant improvements to your existing windows without investing a large amount of money or time.
Homeowners looking to replace older, drafty windows to improve their home’s energy efficiency should examine all their options. New windows are often the most costly and least cost-effective energy efficiency investment you can make. There are, of course, sound reasons besides energy efficiency to invest in new windows, such as comfort, resale value, aesthetics, and even need.
If you have an aging central air conditioner — even if it’s still working — it might pay off to look into replacing it sooner rather than waiting until it fails.
Replacing an inefficient AC unit with a more efficient model could significantly reduce your electric bill; new units are likely to be 20 to 40 percent more efficient than one from the 1990s. ENERGY STAR-certified systems are even more efficient. Replacing an aging system now, before summer starts, could help you avoid delays or price premiums.
