New boiler installation in Plymouth

A combi boiler is also known as a combination boiler. Combi boilers are highly efficient and compact, making them ideal for smaller homes. The name Combi comes from the fact that these boilers are able to act as both a water heater and also a central heating unit. 

Combi boilers work by heating water directly from the mains, so you don’t need a hot water storage cylinder or cold water tank. This is ideal for smaller properties without airing cupboard or roof space. This heating method also makes them very energy efficient and affordable to run, as water is not heated and stored. 

The majority of new boiler installations in Plymouth are for combi boiler`s.

A system boiler directly heats your central heating and also produces hot water for your storage cylinder. It is a heat only boiler and works in a similar way to a conventional boiler, however it includes additional units within the boiler itself such as an expansion vessel and a pressure release valve.

A hot water storage tank will always be required with a system boiler, as it needs somewhere to store the water it has heated. A system boiler doesn’t however require a cold water tank, saving space and making them more suitable for smaller homes than a regular boiler.

A conventional boiler system is made up of a number of parts including a boiler, heating controls, a hot water cylinder, a cold water storage cistern plus a feed and expansion cistern. A regular boiler can often be found in older, larger homes and less are being installed as time goes by.

A conventional boiler system is fed by two tanks which are located in the loft. One of these, the cold water storage tank, draws cold water from the mains supply for your hot water. The other is the feed and expansion tank, which feeds the boiler system and manages any water that expands in the system after being heated.
