Selecting the optimum gas fired boiler







Selecting the optimum gas fired boiler

Selecting a new or replacement heating boiler can be a difficult chore. The cost will be one major influence but there are other factors, you will want to appraise when and how much hot water you will use at any time, the storage space you have available for heating boiler component parts and how green the gas fired boiler is.

The primary gas boiler types are:-

gas back boilers

Some households still have back boilers, these are are commonly obscured at the back of a chimney, with a fire in front to obscure them. Low water pressure is a problem with these back boilers and you will not be putting in one of these unless it is a replacement, space can be an issue and there needs to be somewhere to obscure the boiler. Having said this your best option could be a replacement if you currently have this type of boiler.

Back boilers have not been very economic in the past, but the modern gas back boilers are more cost-effective now, so by changing an aging back boiler, you might make a large savings on your heating bills with improved boiler efficiency.

The latest Combination heating boilers

In the last few years the combi gas fired boiler has become the most popular type of gas boiler sold. They are efficient and small enabling them to be fitted into small spaces. They also heat cold water instantly meaning that you do not will have to wait for a hot water tank to heat up – and your hot water supply will be unlimited.

Combi boilers use less gas than the other types.. The heat loss pattern is reduced as the hot water storage tank in other gas fired boiler systems is got rid of. Look out for someone turning on all the hot water taps in your home whilst you are running a hot shower as it could temporarily turn cold.

Unvented central heating boilers

A hot water tank is used by a system gas fired boiler to store of water. This will demand space in your home. The installation tends to be easier and lower-cost with this type of boiler as the other central heating system components are built in.

An advantage of the hot water cylinder is that it helps the drawing of multiple streams of hot water simultaneously. If the hot water cylinder is fitted high in the house you will also get good water pressure.

Open vent central heating central heating boilers

an open vent boiler is the most familiar type of central heating boiler. If you have one of these you will require to water storage tanks to be installed in the attic, additional space is also required for the hot water storage tank fitted in the airing closet.

One of the attic cylinders feeds the hot water storage tank with water from the mains.

Water expands when heated and this is helped by the 2nd tank in the loft. Showers, taps and running baths can be run in any room simultaneously, but be aware that if the tank should become cold it will take a while to reheat.
