Department of Energy (DOE) in 1987, and effective from 1990, required an Energy Factor (EF) of 0.525 for a 50 gallon (190 L) gas-fired water heater
In the baselining of this condensation modeling methodology, a non-compliant common venting of a fan-assisted furnace and natural-draft gas-fired water heater
into both interior and exterior masonry chimneys is simulated with VENT-II and CFD.
The youngsters, their father Neil and his partner Ruth Beatson were staying in a bungalow at the Corcyra Hotel when they were overcome by fumes from a faulty gas-fired water heater
of sediment on the bottom of a gas-fired water heater
, 70 percent more fuel is required to heat the water.
* Accessory available that cuts off electricity to power vents on gas-fired water heaters
Using gas-fired water heaters
for homes instead of electric resistance water heaters, for example, ultimately reduces greenhouse gas emissions by one-half to two-thirds.
(Average winter temperature in the unheated cellar that has the three gas boilers and three gas-fired water heaters
is 65 degrees.) I sure don't want any mold to grow.
EF ratings typically range from 0.75 to 0.95 for electric water heaters, and 0.50 to 0.70 for natural gas-fired water heaters
Noritz to boost production of gas-fired water heaters
Consumer Product Safety Commission (CPSC) estimates that gas-fired water heaters
caused 5,100 fires, 30 deaths, and 360 injuries in 1993 alone.(1)
