Potterton System Boilers |
Boilers from Potterton |
|
System boilers neatly incorporate a number of components found outside of the boiler on traditional installations - the pump for example. Another is the expansion vessel, which replaces the tank in the roof-space. So installation is easier and quicker and the risk of burst pipes in winter is eliminated. Performa System boilers are fully factory assembled with a neat, smooth and easy to clean casing. A pre-plumbing jig with isolating valves allows pipework to be connected and flushed prior to fitting the boiler. A choice of concentric or twin pipe flue systems facilitates a wide choice of location.
