The Combi Boiler has become the ideal choice for domestic heating in homes across Britain. So what makes them so popular? Combi boilers provide both heating and hot water directly from the mains. They are also highly space efficient as there is no need for a separate hot water tank.

Advantages

Providing the property with instantaneous heating to radiators and hot water supply, combi boilers are not only convenient but highly efficient as they only produce heat when required. This is also great if you’re looking to save money on your heating bills. Combination boilers can also save money through the installation process as it is not necessary to install a tank in the roof space, meaning less piping and a speedier fitting.

A combi boiler not only saves home owners money but saves on room too, making them ideal for homes where space is at a premium. The unit will conveniently fit within a standard sized kitchen cupboard, which is a highly appealing feature, especially with the compact ranges on offer.

There is a great range of combi boilers to suite any household size. Available in a variety of heat outputs and flow rates, the correct boiler will entirely depend on the number of bedrooms and bathrooms in the property. This is determined by your gas safety registered engineer before installation.

Combi boilers are also available in a choice of fuel types, so even if you depend of a stored fuel source away from the mains gas supply you can opt for an LPG combi boiler. No matter what sized combi boiler you chose, you can be assured that the efficiency rating is an optimal rating. New combination boilers are manufactured to rate highly for both ErP and SEDBUK. Designed to improve the efficiency of heating and hot water products, ErP and SEDBUK measure performance and then rate them. The ratings then allow for easy comparison of boilers between brands such as Worcester, Vaillant and Ideal.

Disadvantages

There are some disadvantages to the combi boiler in regards to suitability for particular households. Combi boilers work particularly well in households with a moderate demand for hot water. Combination boilers are not suitable for homes which exceed one bathroom as the higher demand will negatively affect performance.

A combi boiler is also unsuitable for homes with multi-jet showers; this is due to an excessive demand for hot water which combi boilers cannot provide. If you have a number of bathrooms, or a pump assisted power shower a system boiler would be more suitable.
