Gas systems: a basic guide to components and typical applications

By Ellyn Peratikou

There are two types of gas boilers, LPG and natural gas or piped gas. The former is often found where the property is of mains. Natural gas is a far more affordable option due the nature of its supply and manufacturers have the largest ranges available in this fuel type. All gas boilers need to vent the emissions to the outside and this is done by a flue kit. All flues are now powered and push the emissions safely away to the outside.

Previous flues relied on natural draft and these occurred in the form of balanced flue, large square RS units, or conventional flue CF. Both where prone to back draft and needed constant maintenance and checking to make sure they where not dangerous. It also made the appliance very inefficient and in the case of balanced flue very constrained in its location in the house.

All gas boilers are now fanned flued and condensing which re-uses the exhaust gases to heat the incoming mains to a more satisfactory temperature. Gas boilers have the benefit of range and can start from 12KW (30,000 BTU) up to 65KW ( 220,000 BTU) depending what is required.

Gas boilers can suit all applications and can be combination, conventional or system boilers. All gas boilers are far more efficient and cleaner than oil boilers. With the advances in boiler technology it now means that you can locate your boiler in any room in the house and there are a myriad of flue options to allow the installer to choose the best option for the location.
