An instant water heater; a compact unit that supplies warm water instantly

An instant water heater supplies hot water instantly at the point of use eliminating long pipe runs. You no longer have the necessity to connect to a centrally located hot water storage heater for hot water supply.

The instantaneous water heater is unvented. It is a compact unit that is available as an over sink instant water heater or an under sink instant tankless hot water heater.  


The use of an instant water heater

The instant hot water heater can be used to provide warm water for both commercial and domestic applications. The direct fed water mains instant water heater is an ideal unit for washbasins. 


It can be used in: 

  • garages
  • toilets
  • houses
  • extensions
  • ensuites
  • loft conversions
  • commercial washrooms
  • offices
  • workshops

It allows you to supply warm water to a basin for a hand wash in out of reach locations where you already have cold water supply. All you need for a hand wash is an instant tankless hot water heater that is easy to install. 


Important information regarding the use of an instant water heater 

An instant water heater will provide hot water almost instantly (within 10 seconds). A single phase instant water heater is only suitable to supply hot water to a washbasin.

The limited flow rates make it unsuitable to supply your bath, shower or kitchen sink with sufficient water. Please note that these flow rates vary in summer and winter because of the temperature of the incoming water. The Pow 18 LCD is a three-phase current model that can, however, supply hot water to a shower or shower cabin.
