Re: Tankless Hot Water Heaters
The operating cost will be no more than a tank electric heater and will likely net a 10 -15 % reduction in utility costs ( possibly more ). Remember you are only using electricity to heat the water when there is a demand and not to maintain the temperature of the standing water in a tank type.
However, a major consideration will depend on where you live and the incoming water temps during winter months. The colder the incoming water temperature the lower the gpm output. Which might require a larger unit to accomodate heavy use during those times --- this will require having a large enough electrical service .
