Instantaneous/Tankless Water Heaters

Instantaneous or tankless water heaters are very common in Europe and Asia. Unlike storage heaters, instantaneous water heaters heat water only upon activation by switch or water flow. Basically, an instant heater switches on when water enters the heater. Then, the heating element or gas burner activates, heating the water that then goes towards the outlet. Instantaneous heaters are commonly categorized as either single point or multipoint These are applications of the heater. With single point application, there is only one point of use of hot water -- usually the shower -- and the water isolation point, where the water flow is controlled , is located before the inlet of the water heater. With a multipoint application, hot water is supplied to two or more devices, like the sink and the shower. Each device supplied by the multipoint application is an isolation point. Because the isolation points are located after the outlet of the multipoint heater, the water through the heater is pressurized. Advantages: - They do not suffer from standby heat loss - They have much smaller space requirements Disadvantages: - They usually will have a certain minimum flow rate required to activate - Water temperature is dependent on volume of water; for a given heating setting, higher/stronger water means lower temperature Types and Categories Thermostatic Instant Electric Heater - BW405 Thermostatic Shower Heater - Atmor 905 Smart Thermostatic Multipoint Inline Heater Electric Instant/Tankless Water Heaters - Atmor Series - BlueWave Series Gas-Fired Tankless Water Heaters - JSD12 Gas Water Heater - JSD24 Gas Water Heater
