Gas Heaters

Gas Heaters will heat your pool and spa water when the incoming water is heated by an open flame burner then returns to the pool after the heat has been transferred through the heat exchanger. Gas Heaters are available in Propane and Natural Gas. Gas heaters are offered in millivolt and electric start models. Electric start heaters can have analog and digital controls. If you are purchasing a Natural Gas Heater and live in the states of California and Texas, you have to purchase a unit that is called a Low NOx unit. Low NOx units are environmentally friendly. Low NOx units are specifically engineered to produce lower amounts of nitrogen oxide emissions. This law only applies to Natural Gas Only, Not Propane (LP).
