Should you install a combi boiler? Here is what you need to know . . . .

So, what exactly is a combi boiler I hear you ask?

Well, a combi boiler (which is short for combination boiler) combines a water heating system and a central heating boiler into one unit. It therefore handles heating and hot water without needing a separate hot water cylinder located elsewhere in your home meaning it will take up less space.

According to, ‘There are certain features you should look out for when shopping for combi boilers, including: Energy Efficiency; Power Outage; Size; Energy Efficiency. Combi boilers are given a grade based on how energy-efficient they are, with an A rating being the highest. This is a good thing to consider because it will determine how expensive the boiler will be to run.’ Additionally, you should consider the water demand for your household as while combi boilers are highly efficient and will save space, they do not provide as much hot water as a heat only boiler used in conjunction with a hot water cylinder.
