Things to debate when choosing a central heating boiler







Things to debate when choosing a central heating boiler

Selecting a new or replacement gas fired boiler can be a hard task. expense is obviously one factor but there are other factors, the amount of hot water called for at any moment is also important, how much space you have in your house and loft together with how much gas boiler will use up over its lifespan.

We have named in the most common types of heating boiler below to give you supplementary information:-

back boilers

If you live in an older home you might have a back boiler fitted, these domestic back boilers were often fitted in the chimney space out of sight, with a fire in front to obscure them. Low internal water pressure is a problem with these back boilers and you will not be installing one of these unless it is a substitute, space can be an issue and there needs to be somewhere to obscure the boiler. Notwithstanding this if you currently have a back boiler then a straightforward replacement could be your best option.

In the past gas back boilers have not been known as being very economic, but the modern gas back boilers are more cost-effective now, so by changing an aging back boiler, you could make large savings on your annual heating charges.

Modern Combination central heating boilers

The most popular type is now the combi gas fired boiler. They are economical and small enabling them to be fitted into small spaces. They also heat cold water directly meaning that you do not will have to wait for a hot water tank to warm up – as a result you have unlimited hot water.

Combi gas boilers use less energy than the other types. The heat loss profile is reduced as the hot water storage tank in other central heating boiler systems is got rid of. However, for this same reason – the lack of a hot water storage cylinder – your hot bath will be interrupted if anybody else starts running the hot water in your home simultaneously.

Unvented central heating heating boilers

A hot water cylinder is used by a central heating boiler to store of water. You may want to install this in the airing closet taking up precious space. One advantage of this type of system is as many of the central heating system parts are built into the heating boiler allowing a faster and cost installation.

Storing hot water means that you can get hot water from several taps or a bath simultaneously. internal water pressure is enhanced if the cylinder is fitted high in the house.

Open vent system gas boilers

The most popular home central heating is a vented heating boiler. This type of system uses 2 water cylinders, both located in the attic, a lot of valuable storage space is needed as the hot water storage is also required in the airing cupboard.

The hot water storage tank is supplied by one of the storage tanks in the attic.

The second is called the expansion and feed and this enables the water in your central heating to expand and contract. Showers, taps and running baths can be run in any room at the same time, but be aware that if the tank should become cold it will take a while to reheat.
