Your water heater is a forgotten necessity when it’s operating correctly. When it’s not, it commands attention while wreaking havoc on your home. There are some basic things you can do, which we’ve outlined in the past, but let’s look at some ways your water heater is already keeping your home safe, sound and in supply of hot water.
Most residential gas tank units incorporate what’s called flammable vapor ignition resistant (FVIR) technology. Sound fancy? It is. This is a complex design that makes your water heater resistant to flammable vapors such as gasoline, paint thinner and cleaning solvents that may build up near the base of the unit. Should there be a small combustion, the FVIR technology keeps burning vapors inside of the combustion chamber until they burn out.
If your house has a small tank attached to the water heater, this is known as an expansion tank. It absorbs the excess pressure which happens due to the thermal expansion. If the pressure is allowed to build, it damages valves, fixtures, lines and unit.
Some tanks will have what’s called a vacuum relief valve, which is recommended for all side (or bottom) cold inlet units. This prevents back siphonage, eliminates burned-out electric elements and collapsed tanks.
With these and other safety features, and proper maintenance from you or us, your water heater should last for a very long time. However, a deteriorating water heater can go from bad to worse very quickly. If you find a leak or think your water heater is failing, call us immediately.
