What is a Combi Bolier?

A combi boiler provides heating and hot water directly from the boiler.
A combi (or combination) boiler is an ingenious space-saving idea, and an increasingly popular choice in UK homes. In fact, combi’s now account for well over half of all the new domestic boilers installed in Britain every year.
A combi boiler is both a high-efficiency water heater and a central heating boiler, combined (hence the name) within one compact unit. Therefore, no separate hot water cylinder is required, offering space saving within the property.
Further benefits of a combi boiler include hot water being delivered through your taps or shower at mains pressure. So you can enjoy powerful showering* without the need for a pump.
Another combi boiler benefit is that it can generally save you money on installation time and costs, since no tank in the roof space means less pipe work and a shorter installation time.
How do we fit a combi boiler?
Simply put, no one system is the same, and what we describe is purely an example of the work we do. Whenever we give you a quote for a new combi-boiler system one of our engineers will always follow up with a site survey. This is where we finalise everything that you the customer wants, and what we can do for you.
Firstly dependent on what you’re having done, we will remove your old central heating system and have this taken away. Then we begin installing the new boiler, at Boilertrust this usually involves two Gas Safe engineers and one labourer on site. As we install your new combi boiler we make sure that all the systems are working correctly, and once installed we check that your central heating system is heating your property correctly. This involves running tests to ensure that the system is safe.
Once we’ve run our tests on the Combi boiler system and are satisfied, we commission and register our work with the appropriate organizations and authorities.
