Matters to look at when selecting a boiler

Identifying a new or substitute gas fired boiler can be a hard task. cost is plainly one element but there are other factors, whether you will use one hot tap or several at the same time it is to be considered, the space accessible in your house and how economic your new central heating boiler will be.

We have listed in the most familiar types of gas fired boiler below to give you supplementary information:-

gas back boilers

In the past gas back boilers were frequently installed in houses, if you look cautiously in the chimney you might see the back boiler fitted out of view, the fire obscuring the back boiler at the back of it. Low internal water pressure is a problem in these gas boilers and they are now only installed as substitutions, installation requires a lot of space and in this type of boiler it needs to be obscured someplace. However, if you do already use a back boiler, then it could be the best alternative for you when the time comes to exchange it.

Back boilers have not been very efficient in the past, but the modern domestic back boilers are more economical now, so by putting in a new back boiler, you could cut your heating bills through improved efficiency.

Modern Combination gas boilers

In the last few years the combi gas fired boiler has become the most popular type of heating boiler sold. They are small; fitting into cupboards, and really economical to operate. As they heat water direct from the mains, you do not have to wait for water to heat up – as a result you have endless hot water.

A combi is also more cost-efficient than other types of gas boiler. The heat loss pattern is reduced as the hot water storage cylinder in other gas boiler systems is eradicated. The downside of this is that combi gas fired boilers sometimes struggle to supply several hot water taps simultaneously.

Unvented central heating boilers

central heating central heating boilers store hot water in a hot water tank. You may need to install this in the airing cupboard taking up valuable space. Many of the components of the heating and hot water central heating system are built in, which means that installation is swifter, cleaner, smoother and more efficient.

Storing hot water means that you can run hot water from many taps or a shower simultaneously. You will also get great water pressure.

Open vent system central heating boilers

The most popular home system is a vented heating boiler. two water storage tanks will be fitted in the attic with an open vent boiler, additional space is also required for the hot water storage cylinder fitted in the airing closet.

The hot water storage cylinder is supplied by one of the tanks in the loft.

The other cylinder in the loft facilitates expansion of the water in the central heating system when it heats up. Showers, taps and running baths can be run in any room concurrently, but be aware that if the cylinder should become cold it will take a while to reheat.
