Regular Boilers

Regular Boilers can be seen as conventional, or traditional boiler types. For most people upgrading their boilers these days, they will have a conventional system.

They are conventional because they work using a system which has been around for many decades. This is based on a boiler – fed by a cold water storage cistern – heating water on a regular programme which is then kept hot and ready for use in a copper cylinder, which goes to feed radiators and hot water taps. There are also a few controls (boiler, radiators etc) and quite a few lengths of copper piping. All nice and simple. And the system itself hasn’t changed that much. What has changed is the rapid change in boiler technology.

Almost all regular boilers are nowadays condensing boilers. Indeed, when replacing an old boiler, or specifying one from scratch for a new-build, all boilers have to be of the condensing type, unless your property cannot accommodate the installation of such a boiler (e.g. you have a Back Boiler). The reason? Condensing boilers are the most efficient and use two heat exchangers. One to heat the water from the main combustion process, the other to capture otherwise wasted heat in the exhaust.

This double capture of the heat gives condensing boilers a SEDBUK rating of A (90% and above). This is why if you have a boiler that rates less than A, or perhaps B (a G, or X, or unrated for example), you’ll literally be burning money every year. And an A rated boiler not only helps you save money, it helps the environment.

So, the main advantages with Regular Boilers are a high hot water flow rate and because the boiler is fed from a cold water feed tank, the water pressure is not so critical as with a Combi Boiler.

The main disadvantages are usually higher running costs and more space needed to house a bigger system. Also, because there is more kit and pipe work, there is greater heat loss.
