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

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

You might want to consider the Glow Worm Energy 15kW for your house or flat if you are looking for a heat only boiler.

Sometimes called regular boilers, conventional boilers or standard boilers, heat only boilers require a cold water tank (often kept in the loft) and a hot water cylinder and an immersion heater (often kept in a landing or airing cupboard) to work. The immersion heater heats the water and keeps it warm.

With a heat only boiler, you pre-set a timer to tell the system when you want it to provide you with hot water and central heating. Remember though, if you don't program it and there's no water left in the hot water cylinder, you'll have to wait up to an hour before running a bath or shower.

Heat only boilers are better for larger homes or homes with more than one bathroom where there is a high demand for hot water at certain times of the day. Unlike with combi boilers where water pressure, volume and temperature drops if, for example, more than one person is using a hot tap, regular boilers can cope with multiple members of your household wanting hot water at the same time.

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 boiler engineers would recommend that a boiler with this output level would be most suitable for smaller homes and apartments with up to 10 radiators and one bathroom.


Glow Worm Energy 15kW dimensions

The Glow Worm Energy 15kW stands at 700 mm tall, 375 mm wide and 280 mm deep.

Glow Worm Energy 15kW – condensing or non-condensing?

The Glow Worm Energy 15kW is a condensing gas boiler - we strongly recommend that you choose one of the latest condensing models if possible.

With a condensing boiler, you save money on your gas bills because your boiler captures and recycles the heat present in the flue exhaust gases and water vapour condensation for re-use, meaning they operate far more economically and efficiently.

Is the Glow Worm Energy 15kW heat only boiler an environmentally friendly choice?

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 UK, central heating is responsible for 14% of greenhouse gas production. Domestic gas boilers emit large quantities of nitrogen dioxide in British cities.

Would choosing a Glow Worm Energy 15kW heat only help in the fight against climate change? What do the performance statistics suggest?

Under current UK law, all boilers must achieve a minimum energy efficiency level of 92% (a low to good SEDBUK "A" rating). The minimum level was raised from its previous 88% in April 2018.

Energy efficiency scores are intended to inform consumers of the amount of energy used and wasted when a boiler is in normal operation.

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

The Energy Related Products (ERP) Directive's aim is to reduce the harmful gas emissions created during a product’s manufacture and active end use right through to its disposal.

The ERP rating for the Glow Worm Energy 15kW is "TBC".

Am I covered if the Glow Worm Energy 15kW heat only boiler breaks down?

The parts and labour warranty on the Glow Worm Energy 15kW covers all repair-related costs for 2 years while the heat exchange warranty covers you for [Heat Exchange Warranty] years.

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

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

Glow Worm’s Energy 15kW is one you might consider if you’re looking for a heat only boiler for your house or flat.

You may hear a heat only boiler being referred to as a conventional boiler, a standard boiler or a regular boiler, but they're all the same. Heat only boilers require both an immersion and a cold-water tank to function, the latter usually being situated in the loft. Water is kept warm throughout the day by the immersion cylinder for use when needed.

With a heat only boiler, you program the times at which you want to have hot water and central heating, but if you forget and there's no hot water left, you’ll have to wait for it to heat up before you have your bath or shower.

If you have a home with more than one bathroom, or a larger family, a heat only boiler will probably suit your needs. This is because, if you opted for a combi boiler instead, the water pressure, volume and temperature drop when more than one point is in use - for example if you have a shower while running hot water in the kitchen or another bathroom.

Is a Glow Worm Energy 15kW heat only a suitable choice for my house or flat?

To determine that, we need to consider the size of the boiler. However, size doesn't refer to how big a boiler is - it means the size of its "output".

Your boiler’s output is a measurement of the power it has available to heat the volume of water required for your taps and radiators. The higher the output rate, the more water it can heat.

You need to be careful to select a boiler with the optimal level of output for your property though. That's because, if your boiler output is too low, your water and radiators will often not be as hot as you want them to be. If the output is too high, you’ll be paying more for gas than you need to.

The output of the Glow Worm Energy 15kW heat only is 15 kW, so which types of property would this Glow worm Energy 15kW heat only boiler be appropriate 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.


How large is the Glow Worm Energy 15kW?

The Glow Worm Energy 15kW measures 700 mm high and 375 mm wide by a depth of 280 mm.

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

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.

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

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about climate change.

As much as 14% of the UK’s greenhouse gas production derives from our domestic central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in Britain's largest cities.

Would the environmental impact of installing a Glow Worm Energy 15kW heat only in your home be positive? Let's look at the numbers.

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.

In 2015, the Energy Related Products Directive (ERP) came into force. The legislation applies to all products that consume energy - in production, during their active life, and at the point of final disposal.

The ERP was introduced to incentivise manufacturers to create products that emit fewer harmful gases with the larger aim of protecting the wider environment.

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

If the Glow Worm Energy 15kW breaks down, will I be covered by the warranty?

The Glow Worm Energy 15kW boiler offers a parts and labour warranty of 2 years.
