How Tankless Water Heaters Work

Modern tankless water heaters are nearly perfected perfect technologies employing computer controls, powerful gas burner and water control mechanisms to give endless, precisely-temperature-controlled hot water. When a fixture in the home opens and water flows, the tankless’ flow sensor immediately detects a need to engage.

A quick purge of the combustion chamber is accomplished by the powerful, variable-speed draft-inducer fan. Then, an ignition sequence is performed, lighting the tankless’ powerful burner. Water in the heat exchanger quickly heats up and hot water is supplied. This entire sequence happens very quickly, so that hot water at fully temperature is leaving the tankless within 4 seconds the fixture opening.
