Birmingham Conventional Boiler Installation
Our central heating prices and combi boiler prices are some of the best around. Furthermore, you’ll be happy to know that all the gas boilers we provide are from established and reputable brands. As a rough estimate most flats, apartments and smaller houses with up to ten average size radiators will require a 24 to 27kW combi boiler. Larger properties with a higher demand for hot water are likely to be more suited to a 28 to 34kW or 35 to 42kW combi boiler. This information is only a guide, but will give you a good idea when discussing your needs with a heating engineer.
CONVENTIONAL VENTED BOILER REPLACEMENT
Conventional gas boilers also known as Open Vent Gas Boilers and Gravity fed systems come with a separate hot water cylinder are the heart of most old-fashioned heating systems. They provide heat for radiators directly and produce hot water which is stored in a separate hot water cylinder. The cold water is normally supplied by a cold water cistern, usually in the loft above the boiler (gravity feed) and there is also a separate expansion cistern.
These arrangements take up much more space than a combi boiler system, but because there is a large tank of stored hot water you can use several taps at once. This makes this type of system more suitable for larger houses with two or more bathrooms.
Unless a hot water cylinder is very well insulated it usually loses heat into its surroundings, thereby wasting energy. And the amount of hot water you can use is limited by the size of your cylinder. For instance you might run a bath, and then need to wait for the boiler to heat up the water in the cylinder again before you can run another.
High flow rate for domestic hot water
More than one hot tap / shower can easily operate at same time
Once the water in the storage cylinder runs out you have to wait for it to reheat.
You'll need to find space for the cylinder (usually an airing cupboard)
The bulk feed and expansion tanks are usually sited in the loft.
