Glow worm Energy 25kW System Gas boiler frequently asked questions

Is the Glow Worm Energy 25kW a combi, system or regular boiler?

The Glow Worm Energy 25kW is a gas system boiler.

Ever since system boilers arrived on the market, they have been a popular choice in new homes. In the same way as regular boilers, they work along with a hot water cylinder, which is usually located in an airing cupboard. Since system boilers do not require a separate cold water tank, they appeal to some homeowners, especially if they intend to convert their loft in the future.

Their design includes (often built-in) circulating pumps to send hot water to your taps and radiators. They're also quicker and easier to install because you don't need to find room for and fit a water storage tank.

In addition, system boilers require programming for the flow of heat and hot water, which is not available right away. In any case, the cylinder keeps the water hot for use later, so you shouldn't have to wait for your bath as long as you set your timer and leave it on for long enough to heat sufficient water to use throughout the day.

Is the Glow Worm Energy 25kW system boiler the right choice for my house or apartment?

You should make sure that the boiler you install in your property is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

Your boiler has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your gas bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Glow Worm Energy 25kW system's output at 25 kW, which types of property would this Glow worm Energy 25kW System boiler be most appropriate for?

An experienced boiler engineer would recommend that this Glow worm Energy 25kW System boiler would provide adequate heating and hot water for medium-sized homes and larger apartments with up to 10-15 radiators and two bathrooms.


How big is the Glow Worm Energy 25kW?

Glow Worm’s Energy 25kW is 700 mm tall, 390 mm wide, and 280 mm deep.

Is the Glow Worm Energy 25kW condensing or non-condensing?

Condensing boilers convert the warmth present in flue exhaust gases and water vapour condensation into heat which they then recycle to increase the temperature of the colder water returning to your system.

We recommend that homeowners choose a condensing boiler like the Glow Worm Energy 25kW for this reason - the more recent your model the better because the technology improves every year.

You'll benefit from lower quarterly gas bills and condensing boilers are also much more environmentally friendly.

Is the Glow Worm Energy 25kW system boiler an environmentally friendly choice?

More and more homeowners are aware of the importance of how we heat our homes and its impact on climate change and other environmental issues.

Nitrogen dioxide emissions in Britain's largest cities are at dangerous levels and this has been caused by gas boilers. In fact, 14% of the UK’s greenhouse gases are produced by central heating.

Would the environmental impact of installing a Glow Worm Energy 25kW system in your home be positive? Let's look at the numbers.

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 Glow Worm Energy 25kW was awarded an efficiency rating of 89.3% with a SEDBUK band rating of "B".

The Energy Related Products Directive (ERP) intends to reduce the amount of energy consumed by individual products over their entire lifetime, from the initial manufacturing process to final disposal and at all points in between.

The legislation is designed to encourage manufacturers to create products that are more environmentally friendly and which result in a reduction in harmful gas emissions.

The ERP rating for the Glow Worm Energy 25kW is "A".

If the Glow Worm Energy 25kW system boiler breaks down, am I covered?

On the Glow Worm Energy 25kW, the manufacturer offers a parts and labour warranty of 2 years.

Is a Glow Worm Energy 25kW system the right boiler for my house or flat?

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

A boiler’s output indicates the amount of power it can use when heating the water which it then sends to your taps and radiators. The higher the output rate, the more water it can heat.

If a boiler’s output is too low, there will be times when your hot water might not be as hot as you want it to be. If it is too high, you’ll likely be paying more than you need to for your gas.

Measured in kilowatts, the Glow Worm Energy 25kW system's output level is 25 kW, so which types of property would this Glow worm Energy 25kW System boiler be an appropriate choice for?

A heating engineer would recommend that this Glow worm Energy 25kW System boiler would be a suitable installation choice for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


What size is a Glow Worm Energy 25kW boiler?

The Glow Worm Energy 25kW is 700 mm tall, 390 mm wide, and 280 mm deep in size.

Is the Glow Worm Energy 25kW non-condensing or condensing?

The Glow Worm Energy 25kW boiler is a condensing gas boiler and we recommend that you select one of the latest models if possible.

Condensing boilers reduce homeowners' gas bills and are better for the environment. They do this by capturing and recycling the heat still present in the flue exhaust gases and water vapour condensation produced when boilers burn gas to generate the power they need to operate.

Is the system Glow Worm Energy 25kW boiler energy efficient?

How we heat our homes and the effect that has on climate change has become important to many homeowners worried about the environment.

In the largest cities of Britain, gas boilers are responsible for dangerous levels of atmospheric nitrogen dioxide emissions. In total, 14% of the UK’s greenhouse gases are produced by central heating systems.

Will installing a Glow Worm Energy 25kW system be a positive contribution to the environment? Let's see what the experts say.

Boilers manufactured or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to this, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The Glow Worm Energy 25kW has been given a rating of 89.3% for energy efficiency, equivalent to a SEDBUK "B" rating.

The ERP (or Energy Related Products Directive) is European legislation which applies to all products that consume energy throughout their lifetime.

Its purpose is to encourage manufacturers to offer products that are kinder to the environment by reducing harmful gas emissions at all stages, from production and end use right through to disposal.

The ERP rating for the Glow Worm Energy 25kW is "A".

What is the length of the warranty on the Glow Worm Energy 25kW?

The Glow Worm Energy 25kW is supplied with a parts and labour warranty of 2 years.
