Finding the right boiler can be a challenge. There are so many options available, so the process of selecting the right one for you and your family’s need can be complex and confusing. However, there are ways of limiting your options by working out the type of boiler you require (which will depend on the type of property in which you live), and sticking with one reputable company like the Which? Best Buy brand Worcester Bosch.
We have brought together some of the best boilers money can buy – combi, system and regular, so you can make an informed decision.
The most common type of boiler is the combi or combination boiler which provides both heating and hot water. These are best for small to medium-sized properties with one or two bathrooms. There are several benefits to combi-boilers – firstly, new models are highly efficient as they only heat water as needed, but do so very quickly meaning that you won’t run out of hot water as with a boiler that uses a storage tank. There is also no chance of a tank or pipes freezing with a combi-boiler. Also, hot water is delivered with mains pressure meaning you can generally enjoy a powerful shower without the need for a pump. As a consequence of all these benefits, combi boilers are the most popular boiler types in the UK.
