This Electric Combi Boiler provides a cost effective alternative to electric storage heating, oil, solid fuel or LPG systems.

It is an ideal solution to properties with no access to mains gas supply and homes which have gas boiler restrictions e.g. listed buildings and bed-sit sleeping areas. Not only is the Electric Boiler the perfect choice for wet central heating but is also suited to Underfloor Heating.




The Electric Boiler outputs are 12kW, 14.4kW & 24kW Three Phase. The operating temperatures of the boiler can be adjusted using the easy to use Control Panel which boasts an LED display. The temperature outputs range from 30°C-60°C (Hot Water) and 30°C-80°C (Heating).

With superior performance and reliability, the Astro Electric Combi Boiler provides on demand heat and instantaneous domestic hot water. They are suitable for small properties that have a shower and hot water outlets for sinks. In homes with larger hot water requirements, it can be combined with a hot water storage cylinder.

Consumption of the Astro Boiler is highly efficient, due to its superior inner design. With no flue required, the Electric Combi Boiler rapidly provides Heating and Domestic Hot Water.
