I hope your holidays were restful and relaxing.
January’s newsletter is about a safety device found on all the hot
water heaters, and steam and hot water boilers found in the homes and
businesses across America. I
don’t feel this safety valve receives the attention it is do and
because of this many injuries and burns, which could have been avoided
occur. This is the
Temperature and Pressure Relief valve which is found on both hot water
and steam boilers, and hot water heaters. This device is truly a
safety device installed for your protection.
remember watching films at the Heating Institute in Cromwell, CT on
hot water heaters installed without “TPR’s” that would shoot 300 feet
into the air. The TV show
The Myth Busters also performed many of the same tests with the same
results. A hot water
heater, without a Temperature and Pressure Relief Valve is a ticking
bomb which can shoot vertically through the framing of a two level
home like a rocket. An
improperly installed TPR can also cause significant burns to anyone
coming in contact with the steam or hot water discharge the boiler or
hot water heater is producing.

The following are five titles of newspaper articles.

Explosion in Union County Pennsylvania October 22, 2007
A water heater is to blame for an
explosion that destroyed an apartment.
When a water heater explodes the force generated is equal to that
caused by the explosion of a stick of dynamite. Can this kind of
an explosion happen in your home? All of the above explosions
were caused by a very simple, but often overlooked, portion of a hot
water heater or boiler, a failed or missing Temperature Pressure
Relief valve. This safety valve releases water, and in this process
relieves pressure in a boiler or hot water heater when the temperature
or pressure within the unit gets too high. Over 21,000 accidents occur
annually in the United States from failed TPR’s.
Temperature and pressure relief valves are included on all
closed-system equipment (hot water heaters and boilers) that are
designed to produce hot water. The purpose of a relief
valve is to provide protection from
