Glow worm Energy 15kW heat only Gas boiler frequently asked questions

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

The Glow Worm Energy 15kW 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 described as a standard boiler, a regular boiler, or a conventional boiler but the terms mean the same. Heat only boilers require a hot water cylinder (usually stored in a landing or airing cupboard) and a cold water storage tank (usually stored in the loft) to operate. Your water is kept warm by the hot water cylinder throughout the day.

A heat only boiler lets you schedule the hot water and central heating you want for set times of the day. However, you'll have to wait before having a bath or shower if you forget to set it and there's no hot water left in the tank.

If you have a bigger family or more than one bathroom, a heat only boiler is a better option than a combi boiler in many cases. This is because a combi boiler struggles to maintain water volume, pressure and temperature to multiple points in a home simultaneously.

Is a Glow Worm Energy 15kW heat only a suitable choice 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.

The output of a boiler is measured in kilowatts and tells you how much power it has available to heat the water it sends to your hot taps, showers and radiators. The greater the demand for hot water in your home, the larger the output you will need.

It is important to select a boiler with the optimal output rate. Choose one with too high an output and your gas bills will be too expensive. Choose one with too low an output and sometimes the water in your radiators and coming out of your taps will be barely lukewarm.

The output of the Glow Worm Energy 15kW heat only is 15 kW kilowatts, so which types of property would this be most suitable for?

An experienced PlumbProud boiler engineer would likely recommend this Glow worm Energy 15kW heat only boiler as suitable for smaller homes and apartments with up to 10 radiators and one bathroom.


What dimensions does a Glow Worm Energy 15kW have?

The Glow Worm Energy 15kW measures 700 mm in height and has a width of 375 mm and a depth of 280 mm.

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

The Glow Worm Energy 15kW is a condensing boiler – we recommend to all clients that they choose the very latest condensing boilers because their efficiency continues to improve year after year.

Condensing boilers recycle heat from both water vapour condensation and flue exhaust gases via a secondary heat exchanger. With this heat, it performs other tasks like warming up colder water returning from your radiator without having to use more gas.

You will save money on your gas bills every year by choosing a condensing boiler as well as benefitting the environment.

Is the Glow Worm Energy 15kW heat only boiler rated as environmentally friendly?

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on 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.

Do the figures suggest that installing the Glow Worm Energy 15kW heat only at your property would help in the fight against climate change?

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 15kW has been given a rating of 89.3% for energy efficiency, equivalent to a SEDBUK "B" rating.

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".

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

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

Glow worm Energy 15kW heat only Gas boiler frequently asked questions

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

The Glow Worm Energy 15kW 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 Glow Worm Energy 15kW heat only boiler a suitable choice for my property?

Selecting the right boiler for your property means selecting a boiler that is the right size. And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

The output of a boiler is measured in kilowatts. The output level determines the maximum power a boiler can use in heating the water needed for the baths, showers, taps and radiators in your home.

It's important to choose a boiler with an appropriate level of output for your property. Your boiler should be able to cope with periods of peak demand in your property and not just your average usage.

An output rate that is too low will result in an inadequate supply of hot water, while an output that is too high will mean the boiler will cost more to run than is necessary.

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

Most experienced boiler engineers would recommend this Glow worm Energy 15kW heat only boiler as a suitable option for smaller homes and apartments with no more than up to 10 radiators and one bathroom.


Making space for the Glow Worm Energy 15kW

The measurements of the Glow Worm Energy 15kW are 700 mm by 375 mm by 280 mm.

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

The Glow Worm Energy 15kW 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.

How energy efficient is the Glow Worm Energy 15kW heat only?

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

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.

Is the Glow Worm Energy 15kW heat only boiler an environmentally friendly choice for your home? Here’s what the figures say.

All boilers manufactured in the UK from April 2018 must achieve a SEDBUK “A” grade and an energy efficiency rating of 92% or above. Before that, the minimum was 88% - efficiency ratings of 88% and 89% were scored a “B” and 90%+ an "A".

A boiler's energy efficiency rating describes how much energy it uses and wastes during its standard operation.

The energy efficiency of the Glow Worm Energy 15kW was rated at 89.3% with a SEDBUK grading of "B".

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

The aim is to encourage companies to create environmentally friendlier products that reduce harmful gas emissions during manufacturing and when in use by the end client, right through to their eventual disposal.

In the case of the Glow Worm Energy 15kW, the ERP rating is "A".

How long is the warranty offered by the manufacturer for the Glow Worm Energy 15kW boiler?

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