Rinnai's wireless module maintains all of its original features, quickly connects via a two-wire interface and can be utilized with a new Rinnai tankless water heater
or installed on existing Rinnai models manufactured since 2006.
(2010) reported this trend in a field study of tankless water heater
performance in Minnesota.
But how do these tankless water heaters
measure up against traditional heaters?
For example, a gas tankless water heater
with an energy factor of 82% would deliver hot water at an efficiency of 75%, about 15% higher than a typical gas storage water heater.
Even greater energy savings can be achieved by installing a tankless water heater
at major points of use--for example, near the master bathroom, a washing machine or kitchen.
Kyle Murray; vice president of marketing for Waitsfield, Vt.-based Controlled Energy Corp., says tankless water heaters
have seen a dramatic 20 percent to 30 percent per-year increase because the systems offer several advantages that conventional water heaters don't.
I am thinking of installing a tankless water heater
in a unit that has a tank-type water heater and gas furnace located directly over the bedroom in a loft attic.
Small draws of less than 4 gallons (15.1 l) that most strongly affect tankless water heater
performance amounted to 29% of total hot water consumption.
The T-H1, the tankless water heater
from Takagi, doesn't just offer endless hot water at a walloping 10.2 gallons per minute to handle three or four faucets at once.
According to Goldstein Research, tankless water heater
does not generate standby energy loss as compared to conventional storage water heaters which makes the product energy efficient and cost effective.
