Electrastream BEPT 215 Solar Electric Boiler

Electrastream

The Electrastream BEPT 215 Solar is a pre-assembled electric boiler system featuring 215 litre hot water storage capacity, a 9 kW tri-core titanium heating element and is available with the added benefit of utilising renewable energy sources such as solar, air and ground source heat pumps.

Applications

Stuart Electrastream electric boilers are suitable for domestic dwellings such as flats, granny annexes, houses, offices and small commercial premises with a heat loss of 9 kW or less where there is no gas supply available.

Important Note: The installation of an effective water conditioner on the cold water supply to this unit is an essential requirement to inhibit limescale build up, maximise heating element longevity and minimise energy consumption.

Failure to install an effective water conditioning device will invalidate the warranty of the Electrastream unit.

Suitable water conditioning devices include the Stuart catalytic water conditioner model C3-22 (product code 44617). For installations requiring flow rates in excess of 22 litres/min please contact Stuart Turner Ltd for guidance.
