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

The Keston Heat 55 is worthy of consideration if you're looking for a heat only boiler for your flat or house.

Heat only boilers, sometimes known as standard boilers, regular boilers or conventional boilers, are better for homes with multiple bathrooms or larger families where members of your household may need to use hot water at the same time as each other, such as a shower in the bathroom and a hot water tap in the kitchen. This is because, unlike combi boilers, they can handle demand from more than one point at a time with no drop in water pressure, temperature and volume.

Heat only boilers use a hot water cylinder with an immersion heater (normally installed in an airing or landing cupboard) and a cold-water tank (normally stored in the loft).

You program a heat only boiler to provide you with the central heating and hot water you need at specific times of the day, such as first thing in the morning. However, if you forget to set timings and there is no water left in the hot water tank, you may have to wait up to an hour before you have hot water again.

Is a Keston Heat 55 heat only boiler right 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.

Your boiler's output indicates the maximum amount of power available to it to heat the water you need to warm your radiators or when you want hot water from your taps. A higher output rate means that your boiler is capable of heating greater volumes of water.

If a boiler's output rate is too low, you'll often find that the water is not as hot as you want it to be. Too high, however, and you'll end up paying more for your gas than you should be.

The Keston Heat 55 heat only boiler has an output rate of 55 kW, so which types of property would this be suitable for?

Most Gas Safe engineers would suggest that the Keston Heat 55 heat only boiler would be a suitable choice for installation in larger properties including detached homes with 15 or more radiators and two or more bathrooms.

What size is the Keston Heat 55 boiler?

The Keston Heat 55 is TBC mm in height, TBC mm in width and TBC mm in depth.

Is this Keston boiler non-condensing or condensing?

The Keston Heat 55 is a condensing gas boiler - where possible, we always recommend to clients that they choose one of the very latest condensing boilers to take advantage of this technology, which improves year after year.

Condensing boilers are more energy-efficient as they capture and recycle the heat contained in flue exhaust gases and water vapour condensation. They then use this heat to perform tasks like warming up colder water returning to the boiler from the radiators.

By choosing a condensing boiler, you'll help the environment as well as save money on your gas bills.

How does the Keston Heat 55 heat only rate environmentally?

Price and performance are two important issues when choosing a boiler but now, for many people in the UK, so is the environmental impact of how we heat our homes and its effect on climate change.

Around 14% of the greenhouse gases produced in the UK is a result of our central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in some of our largest cities.

Would installing a Keston Heat 55 heat only boiler in your home help combat climate change? What do the figures suggest?

Boilers manufactured and installed in the UK are assigned energy efficiency ratings following testing to an agreed set of standards. These scores indicate how much energy the boiler uses and how much goes to waste when it's in operation.

By law, boilers must achieve a SEDBUK rating of "A" subject to achieving a minimum of 92% energy efficiency. Prior to April 2018, the minimum was 88% (88% and 89% on the SEDBUK are graded "B" and 90% and above is graded "A").

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

Is this Keston Heat 55 heat only covered by a warranty?

The Keston Heat 55 boiler offers a parts and labour warranty of 7 years.
