Regular Boilers

What is a Regular boiler?

Regular gas boilers or known as ‘Open Vent Gas Boilers’ 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.

If you're looking to do a full system overhaul most people opt to remove the tanks from the loft and turn their open vent system into a sealed system.

Benefits:
High flow rate for domestic hot water
More than one hot tap / shower can easily operate at same time

Disadvantages:
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.
