Electric tankless water heaters
Htp's space heating boilers provide ultimate comfort and the best overall efficiency ratings while keeping maintenance and operating costs to a minimum. In addition to eliminating losses through long runs of piping, they can save the time and water that's wasted waiting for the water to get hot. Once the heating elements fry, it usually costs about as much to replace the entire heater as it does to swap in new elements. Use less energy than conventional units because of how heat is transferred to water making them more efficient and environmentally friendly. The first step: a pro finds out how many btus per gallon a heater needs to raise the incoming water to 120 degrees (see the map in the next slide). Scale deposits that form in a heat exchanger (or on electric heating elements) slow down heat transfer and constrict water flow. Tankless water heaters, also known as on-demand water heaters, use high-powered burners to rapidly heat water as it runs through a heat exchange...
