About System Boilers

system boiler diagram

System boilers are very economical and heat your home efficiently. Many people cannot tell the difference between a regular boiler and system boiler. So what is the difference? A system boiler takes up less space than a regular boiler because it encompasses the cistern tank and other components but also still provides a solid flow of hot water. HDM recommend a system boiler for slightly larger premises that have more than one bathroom or want a dry (no water tanks) loft area.

The system boiler already has lots of major components of a heating system built in so this makes for a quicker and easier installation. Also the hot water from the system boiler is pumped through the radiators and hot water cylinder, which in turn delivers a faster response and is more economical which means less on running costs. As all the major components are built in it saves space and combines many of the advantages of a regular boiler with a combination boiler.

Pros and Cons of System Boilers

Pros:

  • All major components are built in which means less space is taken up.
  • System boilers are easier to fit and install and are very economical.
  • Provides a faster response for hot water as and when it is needed.

Cons:

  • Unless the cylinder is well insulated it will lose heat.(This is also true for the feed expansion tank in the loft on regular boilers.)
  • If the cylinder is not well insulated you will have to wait for it to heat back up again to run a hot bath.
  • The amount of hot water that can be supplied is dependent up on the size of the tank.

Conclusion

HDM recommend the a system boiler for larger premises that require a lot of hot water for all different facilities. But also don't have the space for a regular boiler that needs a feed expansion tank in the loft.
