  • System Boilers

    System boilers heat your central heating directly to produce hot water for your cylinder - just like a regular boiler works on the principle of stored hot water. However, system boilers differ from a regular boilers in several respects. Firstly, many major individual components of the heating and hot water system are in-built into a system boiler, meaning installation is quicker, neater, easier and therefore more efficient. Secondly, hot water is pumped from the boiler throughout the heating system to the radiators and hot water cylinder, providing a fast response and more economical running costs. The system boiler also removes the requirement for a feed and expansion cistern.

  • Heat Only Boilers

    Heat only boilers - also known as open vent, conventional or regular boilers - heat your central heating and hot water when installed as part of a heating system together with a hot water storage cylinder, cold water storage tank, and a feed/expansion tank. If the boiler you’re replacing is very old, chances are it’s a heat only boiler. You’ll also find that you have a separate circulating pump, instead of inside the boiler. We keep a huge stock of efficient condensing heat only boilers from all the leading brands such as Vaillant,  Baxi and Potterton. In fact, The Plumb Site have all the heat only boilers you need at the lowest prices.
