A System Gas Boiler is Much the same as the Regular Heat only Gas boiler. The Difference between the two is that this creates the chance for you to have a sealed System. The Small tank, (header tank), is Built into the System Boiler and therefore you create a Pressurised sealed system which can combat problems with excess air getting into your Central Heating System.

There was nothing better than a traditional Back Boiler Unit. These Open flued appliances were the favourites as space savers and aesthetically pleasing installations for years. In essence, however, the Back Boiler is merely a regular boiler and is easier to change than you may originally think. Although installations are not allowed we are on hand to help and certain parts are still available.
