After the snow melts, we’re converting our attached garage into an apartment for my folks. We planned to put hot-water baseboard heat in there, like in the rest of the house, but my mom is set on radiant floor heat. Is this a cheap way to heat?
For readers who aren’t aware: Radiant floors provide heat via hot-water tubing or electrical heating elements installed in or under flooring material. As for the cost of keeping a space warm this way: It’s likely to be similar to non-radiant heat using the same kind of fuel. Proponents of radiant floors suggest that this system uses less energy because it allows you to stay comfortable while keeping your thermostat lower. In fact, most homes with radiant floors are set at the same temperature as comparable homes without radiant floors.
If you’re looking to lower your heating costs, the best approach is to reduce the amount of fuel you use. That’s done by keeping your heating system well-maintained and seeing that your space is properly air-sealed and insulated. I suggest talking to a Home Performance with ENERGY STAR® contractor about your garage conversion project. These contractors are specially trained and certified to conduct energy audits, to make recommendations, and to do home improvements that lower energy use by up to 30%. Efficiency Vermont offers up to $2,500 for energy-saving home improvements that have been completed by one of these contractors. Learn more and see the list of Vermont contractors.
If you decide to go with radiant floor heat, keep in mind that electricity is typically one of Vermont’s most expensive heating fuels. Hot-water radiant floors are likely to cost less to use than electric systems. Best of luck making a comfortable new home for your parents.
