Often times we are asked to consult with a potential remodeling client before they close on their new home. Lately we’ve seen a trend in Austin where 3rd Party inspectors are suggesting to clients that they install a Thermal Expansion Tank on their existing hot water heater(s). Because we are getting this request often enough, we felt it was time to do some research on why and how effective these devices are.Austin Remodeling
Some quick facts – as most people know, when water is heated, it expands. For example, when you take a 50 gal hot water heater and warm the water up from 40 degrees F to 140 degrees F you could create almost an entire gallon of thermal expansion. A properly sized and installed thermal expansion tank can be installed to accommodate this increase in volume as the water is heated. Why is this important?
By giving this expanded volume of water some place to go, you can lower the pressure on your existing system, thereby reducing wear and tear on your home’s piping systems, equipment and fixtures. The goal is to expand their lifespan and save you money down the road. And the good news is the installation of these expansion tanks is relatively easy and low cost, even after the fact in a remodeling situation. So by our estimation, they often pretty good bang for the buck.
If you are buying a home, even of recent vintage, that has standard tanked water heater(s), look into the purchase and installation of thermal expansion tanks – they can be a wise investment.
