Which type of indirect water heater is right for you?
Indirect Tanks
Indirect tanks are part of a combination heating system. These water heaters use a home's space heating system to heat the water. HTP's high efficiency indirect water heaters are made with quality stainless steel materials for excellent heat transfer and a longer tank life. Indirect water heaters require a boiler (sold separately). These water heaters work in conjunction with a boiler to heat the water that's circulated through the heat exchanger in the storage tank. When paired with an HTP high efficiency boiler, these indirect storage tanks can generate over 50% more hot water than many water heaters of simliar size.
Storage Tanks
HTP's Storage Tanks increase the storage capacity of any hot water system. These units maintain substantial hot water while only allowing heat losses of less than 1°F per hour. These units are made of high quality stainless steel construction to resist corrosion and last longer. Hot water is released from the top of the tank when the hot water tap is turned on. To replace this water, cold water enters the bottom of the tank, ensuring that the tank is always full.Get help buying
