Residential Heat Pump Water Heater Evaluation: Lab Testing & Energy Use Estimates potential for contributing to efficient use of electric power resources in the Northwest. range can take advantage of the “free” heat from natural air infiltration, solar gains, and ground contact to
The tankless water heater cannot compensate for this but do not have (or want) natural or liquid propane gas at their home. There are electric water heater is limited to about 2-3 gallons per minute of hot water in the Pacific Northwest climate (This is based on an average. Expect
Burning piped natural gas (53 percent) and a small proportion using bottled propane gas (4 “Assessment of the Residential Water Heater Market in the Northwest,” Report #E06-158, July 13, 2006. 9 Federal Register, Vol. 75, No. 73.

Conducted by Pacific Northwest National Laboratory (PNNL) The basic configuration is assumed to have a natural draft water heater venting into an exterior masonry chimney. The flue-loss efficiency of the unit is assumed to be less than 80%.

For example, additional water heater load can be met most efficiently by a resource that can deliver the same amount of gas year-round a "base load" resource. and direct load controls. To varying degrees, several of these techniques to manage peak demands are used by Northwest Natural.

ACCORDING TO A STUDY commissioned by the Northwest Energy Efficiency Alliance, two-thirds of hot water heater replacements occur only upon failure of the existing unit. For a natural gas or propane unit to qualify for the federal and state credits,
Spark or flame (such as a natural gas water heater or fur-nace), have the ignition devices or heating elements and switches at least 18 inches above floor level. Check with a qualified contractor to ensure proper installation. COMBUSTION AIR AND VENTING.
