Free Energy Audit - Water Heater

Last month we called SCE&G about a free energy audit they were offering. We had been meaning to so something like this, but we were procrastinating and companies who do this professionally charge around $400 - so we opted for the free one. The inspectors came and looked around our attic and our crawl space. They inspected our A/C unit and water heater. We also discussed our windows.

Our water heater is a gas storage unit, which means it uses gas to keep a tank full of water heated all the time. It is 14 years old, which means it is near the end of its life. I'd rather take a little time and replace it now, than have to do something when it fails. SCE&G is offering financing if we replace it with a gas tankless water heater. There is also a rebate/tax credit we can take advantage of.

A few years ago I took it upon myself to insulate our water heater. I went to Lowe's and bought a water heater blanket and managed to wrap it around the tank - it was hard, because it was in a small, vented, metal box outside. After the inspectors looked at it, they said the insulation may be restricting airflow to the pilot, or something like that, and I should remove the lower part of the insulation. I did that later the same day and I think it has helped our hot water supply.

We love our tankless water heater.

It's a good thing you had your home's systems checked. And it was free too. That way, you'll be able to see how you can save energy by investing on more efficient systems in the near future.
