Keston Heat 55 heat only Gas boiler frequently asked questions

Is the Keston Heat 55 a standard, combi or system boiler?

The Keston Heat 55 boiler is an option you may wish to consider if you're looking for a heat only boiler for your house or flat.

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 from the Heat range a suitable choice for my house or flat?

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.

The output rate of a boiler tells you how much power it has available to it for heating the water that comes out of your taps and warms your radiators. A higher output rate means that your boiler has more power at its disposal.

You need to make sure you select a boiler with the right output rate. That's because, if your output rate is too high, then your boiler will have more power than it needs but it will cost too much to run. If the output rate is too low, your water may often not be hot enough.

The Keston Heat 55 heat only's output is 55 kW, so which types of property would this Keston Heat 55 heat only boiler be appropriate for?

A PlumbProud Gas Safe boiler installer would recommend that this Keston Heat 55 heat only boiler is appropriate for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


How large is a Keston Heat 55 boiler?

The measurements of the Keston Heat 55 are TBC mm by TBC mm by TBC mm.

Is the Keston Heat 55 a condensing or non-condensing boiler?

We recommend that you select a condensing boiler like the Keston Heat gas Keston Heat 55 for your home if possible because of the environmental benefits and the money you'll save on your gas bills.

Condensing boilers are much more energy-efficient than older, non-condensing models as they capture and recycle the heat still present in the water vapour condensation and flue exhaust gases that your boiler creates when burning gas for reuse.

Is the Keston Heat 55 heat only boiler environmentally friendly?

How we heat our homes has become a major issue for many people worried about climate change and environmental issues in general.

Central heating produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

If you would like your next boiler to help in the fight against climate change, would the Keston Heat 55 heat only be a suitable choice?

Every boiler manufactured and supplied in the UK must have an energy efficiency rating of 92% (SEDBUK “A” rating). These minimums were made law in April 2018 - before that, the minimum energy efficiency rating was 88% (88%/89% = "B" SEDBUK grade, 90%+ = "A" SEDBUK grade).

The Keston Heat 55 was awarded an efficiency rating of 89.6% and a band rating of "B".

Energy efficiency ratings for boilers describe the amount of energy they use and waste when switched on and working.

Keston Heat 55 heat only Gas boiler frequently asked questions

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.

The output of the Keston Heat 55 heat only is 55 kW, so which types of property would this Keston Heat 55 heat only boiler be an appropriate choice for?

Most heating engineers would recommend that this Keston Heat 55 heat only boiler would be suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


What are the dimensions of the Keston Heat 55 boiler?

The Keston Heat 55 is TBC mm tall, TBC mm wide, and TBC mm deep in size.

Is the Keston Heat 55 a condensing or non-condensing boiler?

The Keston Heat 55 is a condensing gas boiler - in fact, we recommend that you select this model or one of the latest condensing boilers on the market as the technology continues to improve over time.

Condensing boilers capture the heat still present in the flue exhaust gases and water vapour condensation created when the gas is burned and they recycle this back into the heating system to warm up the cold water re-entering the boiler from your radiators.

They're much more environmentally friendly and installing one results in much lower annual gas bills.

How does the Keston Heat 55 heat only boiler rate environmentally?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important environmental issues.

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

Do the figures suggest that installing the Keston Heat 55 heat only at your property would help in the fight against climate change?

The energy efficiency rating for a boiler describes the amount of energy it uses and wastes during operation and there are two different ways to measure it.

All boilers manufactured and supplied in the UK must have a SEDBUK rating of “A” subject to a minimum energy efficiency score of 92% or above. Before April 2018, the minimum energy efficiency score was 88% (88/89% = "B" SEDBUK rating, 90%+ = "A" SEDBUK rating).

The Keston Heat 55 scored an efficiency rating of 89.6% and a SEDBUK band rating of B.

If the Keston Heat 55 breaks down, will I be covered by the warranty?

Keston offers a parts and labour warranty of 7 years on the Keston Heat 55.
