The CWLP Energy Experts don't usually recommend a
tankless system as a replacement for a centrally located
traditional water heater. A gas unit, with its standing pilot
light, probably will provide little or no savings over a
well-insulated tank heater. An electric tankless system might be a
little more efficient than a conventional water heater, but the
savings most likely will be too small to offset the high purchase
cost. Tankless heaters are good for some specific point-of-use
applications, such as when distance from a centralized tank heater
makes it hard or inconvenient to get a sufficient supply of hot
water to a kitchen or bathroom. In this case, you could install a
tankless heater right in that room.
Otherwise, we recommend using a traditional tank heater and
taking steps—like wrapping both the tank and the water pipes with
insulation and installing heat traps on the pipes where they exit
the top of the tank—to ensure it will operate as efficiently as
possible.
If your old water heater is a gas unit, consider replacing it
with a 30-gallon or larger electric model and you might qualify
for CWLP's
Water Heater Rebate. To be eligible for the
rebate, you must be a CWLP residential electric customer and must
be pre-certified to participate in the program. |
