Instantaneous Water Heaters  

Instantaneous water heaters offer an innovative solution to delivering heated water at the point of use without the need for centrally stored hot water cylinders. 

These small electrically powered inline water heaters heat water 'instantly' as it flows through the product. This saves on electricity usage as they have no standby energy losses.

Their compact design helps to optimise space in any room size. They are suitable for installation in properties with minimal hot water requirements or remote areas of the home such as the garage.

Safety and reliability is paramount in such heaters which is why they are fitted with a safety cut-out point to prevent overheating.
