Glow worm Energy 15kW System Gas boiler frequently asked questions

Is the Glow Worm Energy 15kW a combi, system or regular boiler?

The Glow Worm Energy 15kW is worthy of consideration if you're looking for a system boiler for your flat or house.

Like heat only boilers, system boilers require a hot water cylinder to work - the cylinder stores and keeps water warm for use throughout the day. Hot water can be distributed to multiple showers and taps simultaneously, making system boilers suitable for larger families and properties with more than one bathroom.

System boilers differ from standard boilers in that they do not require a cold water tank, making them suitable for properties with no loft space or if you are planning a loft conversion. As the boiler's major components, including the circulation pump, are built-in and no water tank is required, system boilers are easier to install than regular boilers.

This type of boiler does not heat water instantly like a combi boiler - instead, you need to use the control panel to set the times when you want heating and hot water to be available for your home.

Should I choose a Glow Worm Energy 15kW system boiler for my house or flat?

It's best to choose a boiler whose size or "output" is right for your property. With a boiler, however, size does not mean how big the boiler is, it means how much power it has.

The amount of hot water you get from showers, bathrooms, and sinks and heat from your radiators depends on your boiler's output (measured in kilowatts). The higher the level of output, the better your home will be heated and you can be more certain that the water from your taps will be as hot as you want.

However, you must be careful. You might not get the hot water you want if your boiler output is too low. If it's too high, you'll be paying more than you need to for gas.

With the Glow Worm Energy 15kW system's output at 15 kW, which types of property would this Glow worm Energy 15kW System boiler be most appropriate for?

An experienced heating engineer would say that this Glow worm Energy 15kW System boiler's level of output makes it a suitable installation for smaller homes and apartments with up to 10 radiators and one bathroom.


Where will the Glow Worm Energy 15kW fit in my house?

The Glow Worm Energy 15kW measures 700 mm high and 390 mm wide by a depth of 280 mm.

Is the Glow Worm Energy 15kW non-condensing or condensing?

We recommend that, if possible, you choose a condensing boiler like the Glow Worm Energy 15kW.

Condensing boilers are more energy-efficient. They achieve this efficiency by capturing the heat present in flue exhaust gases and water vapour condensation and recycling that heat to, for example, warm colder water coming back from your radiators.

By choosing the latest condensing boiler, you'll also notice a significant reduction in your gas bills, particularly if you're replacing a boiler more than 15 years old.

How does the Glow Worm Energy 15kW system boiler rate environmentally?

With growing concern among the public about accelerating climate change, how we heat our homes and the impact this has on the environment has become a major topic of concern for many homeowners.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

Let's take a closer look at whether installing a Glow Worm Energy 15kW system would be a good choice for the environment.

Boilers manufactured after April 2018 in the UK must achieve an "A" on the SEDBUK grading system as well as score a minimum of 92% on a separate energy efficiency test. Prior to that, the minimum was 88% - boilers rated at 88% and 89% were given a “B” rating (90% and higher were given an "A").

An energy efficiency rating describes how much energy the boiler uses and how much it wastes when in use.

The Glow Worm Energy 15kW was awarded an efficiency rating of 89.3% with a SEDBUK grading of "B".

The Energy Related Products Directive intends to encourage all manufacturers to reduce harmful gas emissions connected to the products they make, from the manufacturing stage to final disposal, including when they are in active use.

The Glow Worm Energy 15kW has an ERP rating of "A".

How many years does the warranty period cover on a Glow Worm Energy 15kW boiler?

Glow Worm offers a parts and labour warranty of 2 years on the Glow Worm Energy 15kW.

Glow worm Energy 15kW System Gas boiler frequently asked questions

Is the Glow Worm Energy 15kW a regular, combi or system boiler?

Looking for a gas system boiler for your flat or house? Then the Glow Worm Energy 15kW may be an option you should consider.

System boilers are very popular for properties with limited or no loft space or when homeowners want to keep the space for a loft conversion. This is because, unlike heat only boilers, they don’t require a cold-water tank - however, system boilers do need a hot water cylinder (often installed in an airing or landing cupboard).

Instead of the traditional cold-water tanks, system boilers use their built-in circulating pumps to heat the water needed for your taps and radiators. This also makes them an easier choice for engineers to install as there is one less large component to find space for and fit.

Like a regular boiler, you need to use a control panel to control a system boiler. Set the times when you want central heating and hot water to be available, such as in the morning when there might be greater demand for showers, and it will be there. Although hot water is not available on-demand like with a combi boiler, once the water has been heated it will stay in the hot water cylinder until it’s used up.

Is the Glow Worm Energy 15kW system boiler suitable for my house or apartment?

Whether this Glow worm Energy 15kW System boiler is right for where you live depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output of a boiler is measured in kilowatts and indicates how much energy it can use to heat the water needed for your radiators, taps and showers. The greater the output, the more water it can heat.

A boiler whose output is too high will give you hot water and warm radiators but also higher gas bills, whereas a boiler whose output is too low will result in cheaper gas bills but the water might not always be as hot as you want it to be.

The output of the Glow Worm Energy 15kW system is 15 kW, so which types of property would this model be appropriate for?

Most experienced heating engineers would likely recommend that, at this level of output, this Glow worm Energy 15kW System boiler would be a suitable choice for smaller homes and apartments with up to 10 radiators and one bathroom.


What are the dimensions of the Glow Worm Energy 15kW boiler?

The Glow Worm Energy 15kW is 700 mm in height, 390 mm in width and 280 mm in depth.

Is this Glow Worm boiler condensing or non-condensing?

The Glow Worm Energy 15kW is a condensing gas boiler - this is the type of boiler we recommend to most clients because they're better for the environment and they will save money on annual fuel bills.

A condensing boiler captures and recycles the warmth still present in both the flue exhaust gases and water vapour condensation created when gas is burned to provide your boiler with power.

This means it needs less gas to operate and it uses this extra energy to perform a number of tasks, including heating the colder water that comes back to the boiler from the radiators in your home.

Is the Glow Worm Energy 15kW system environmentally friendly?

How we heat our homes and the damage this does to the environment has become a pressing concern for many homeowners worried about the effects and impact of climate change.

The heating of our homes accounts for 14% of the UK's greenhouse gas emissions. Especially in the big cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Will installing a Glow Worm Energy 15kW system be a positive contribution to the environment? Let's see what the experts say.

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 Glow Worm Energy 15kW scored an efficiency rating of 89.3% and a SEDBUK band rating of B.

The ERP (Energy Related Products Directive) is European legislation that aims to reduce the use of energy at all points during a product's life, from the point of manufacture to when it's in active use right through to final disposal.

The regulation aims to encourage manufacturers to create products that are more environmentally friendly and which reduce gas emissions associated with those products.

The ERP grading for the Glow Worm Energy 15kW is "A".

If the Glow Worm Energy 15kW system boiler breaks down, am I covered?

The Glow Worm Energy 15kW boiler comes with a parts and labour warranty lasting 2 years.
