Is this Keston Heat 55 boiler a combi, system or regular boiler?

Looking for a gas heat only boiler for your house or flat? If you are, the Keston Heat 55 boiler may be worth considering.

You may hear a heat only boiler being called a regular boiler, a conventional boiler or a standard boiler. With a regular boiler, you need to find room within your property for a hot water cylinder with an immersion heater (usually in a landing cupboard or airing cupboard) and a cold-water tank (usually in the loft). The immersion cylinder is what keeps your hot water warm all day.

With a regular boiler, you schedule your hot water and heating for set times during the day or week, but if you forget to do so and the hot water runs out, you'll need to wait for your boiler to heat enough water before you can have a bath or shower - that can sometimes take up to an hour.

A regular boiler is suitable for homes with more than one bathroom or larger families when there is high demand for hot water. Although combi boilers are the most popular type of boiler in Britain, water pressure, volume and temperature drop if there is simultaneous demand from two or more points - for example, someone running a hot water tap when someone else is in the shower.

Is the Keston Heat 55 heat only boiler suitable for my house or apartment?

To determine that, we need to consider the size of the boiler. Size doesn't mean how big it is - it means how big its "output" is.

Boiler output is measured in kilowatts and tells you how much power a boiler can use to heat the water your taps, showers and radiators need. The higher the output, the more power it has.

When choosing a boiler, you should choose one that can cope with the peak demand for hot water in your home and not just your typical usage.

If its output is too low, sometimes your hot water will not be hot enough, but if your boiler's output is too high for your needs, your gas bills will go up and not down.
