Glow worm Energy 12kW System Gas boiler frequently asked questions

What type of boiler is Glow Worm’s Energy 12kW - system, regular or combi?

Looking for a gas system boiler for your house or flat? If you are, the Glow Worm Energy 12kW boiler may be worth considering.

For homes that have a higher-than-average demand for hot water and heating and for larger properties, system boilers are a more suitable option than the more popular combi boilers.

Combi boilers heat water on demand but the amount of water they can actually deliver to taps is determined by the mains water pressure, flow rate and power. System boilers instead use a hot water cylinder that stores and keeps water hot throughout the day. As long as you remember to program the times you want hot water and the cylinder still has water left in it, you should have hot water whenever you need it.

And, unlike heat only boilers that also require a cold water storage tank to work (normally fitted in the loft), system boilers don't, meaning they're quicker, easier and cheaper to install.

Should I install a Glow Worm Energy 12kW system boiler in my house or apartment?

Selecting the right boiler for your home means choosing 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".

Your boiler’s output is a measurement of the power it has available to it to heat the water you need for your radiators or for when you turn on a tap, bath or shower. A higher output rate means it has more power and can heat more water.

It's important to choose an output that matches the demand for water in your home because if your boiler has too low an output, you'll often find only lukewarm water comes out of your taps or heats your radiators. If it’s too high, you’ll be paying more for your gas than you need to.

The Glow Worm Energy 12kW system has an output of 12 kW, so which types of property would this Glow worm Energy 12kW System boiler be appropriate for?

A Gas Safe boiler installer would recommend that this Glow worm Energy 12kW System boiler would provide adequate heating and hot water for smaller homes and apartments with up to up to 10 radiators and one bathroom.


How big is the Glow Worm Energy 12kW?

The size of the Glow Worm Energy 12kW boiler is 700 mm high, 390 mm wide, and 280 mm deep.

Glow Worm Energy 12kW – non-condensing or condensing?

The Glow Worm Energy 12kW 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.

Does the Glow Worm Energy 12kW system protect the environment?

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

About 14% of the greenhouse gases we produce in the UK come from the power needed for central heating. In bigger British cities, gas boilers are a significant source of nitrogen dioxide emissions.

Will choosing to install a Glow Worm Energy 12kW system in your home help the environment? Let's review the figures.

All boilers manufactured and installed in the UK are required to have an energy efficiency rating of 92% or above (or a good “A” SEDBUK rating). Before April 2018, when the law changed, the minimum energy efficiency level permissible was 88% (86-90% is a SEDBUK "B" rating and 90%+ is an "A" rating).

A boiler's energy efficiency rating indicates the amount of energy used and wasted during normal operational performance.

Following its assessment, the Glow Worm Energy 12kW was given an efficiency rating of 89.3% and a SEDBUK grading of "B".

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 12kW is "A".

How long am I covered by the warranty for if the Glow Worm Energy 12kW breaks down?

A parts and labour warranty of 2 years is included with the Glow Worm Glow Worm Energy 12kW boiler.

Glow worm Energy 12kW System Gas boiler frequently asked questions

Is the Glow Worm Energy 12kW a regular, combi or system boiler?

If you are searching for a system boiler for your house or flat, the Glow Worm Energy 12kW is certainly one to consider.

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.

Is a Glow Worm Energy 12kW system boiler appropriate for my house or apartment?

Whether this Glow worm Energy 12kW System boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions - it means how powerful it is.

A boiler’s output is a measurement of the amount of power it can use to provide hot water to your taps and radiators. The higher its output rate, the more water it can heat.

If your new boiler’s output is too low, your hot water might not be as hot as you want it to be. If it's too high, you’ll be paying more for gas than you need to.

The output of the Glow Worm Energy 12kW system boiler is 12 kW, so which types of property would this be appropriate for?

An experienced boiler engineer would recommend that this Glow worm Energy 12kW System boiler would be a suitable installation choice for smaller homes and apartments with up to 10 radiators and one bathroom.


How large is a Glow Worm Energy 12kW boiler?

The Glow Worm Energy 12kW boiler measures 700 mm [H] x 390 mm [W] x 280 mm [D] in size.

Is the Glow Worm Energy 12kW non-condensing or condensing?

We always recommend to clients that they select the very latest condensing boiler for their home.

Condensing boilers like the Glow Worm Energy 12kW are more efficient with the gas they use in operation, meaning that you'll benefit from lower fuel bills. Condensing boilers are also better for the environment.

They achieve their efficiency by capturing and recycling the heat still present in the water vapour condensation and flue exhaust gases created when a boiler burns gas to get the energy it needs. It then reuses that recycled heat to perform a number of tasks, including heating the colder water that comes back to your boiler via the radiator.

Is the Glow Worm Energy 12kW system good for the environment?

As the British public has become more conscious of climate change, many homeowners consider the environment when choosing how to heat their homes.

Approximately 14% of the UK's greenhouse gas production is caused by our central heating systems. The gas boilers in larger urban areas of Britain are mainly responsible for emissions of toxic nitrogen dioxide.

Will installing a Glow Worm Energy 12kW system in your home be a positive contribution to the environment? The figures below will tell you more.

By law, boilers manufactured and supplied in the UK must achieve a SEDBUK rating of "A" and work at a 92% minimum efficiency. Before April 2018, a minimum of 88% energy efficiency needed to be achieved (88/89% = SEDBUK "B" and 90% = SEDBUK "A").

Following official testing, the Glow Worm Energy 12kW was given an efficiency rating of 89.3% with a SEDBUK rating of "B".

Energy efficiency is a measure of how much energy is used and how much is wasted when a boiler is operating.

The Energy Related Products Directive (ERP) came into force in 2015. This legislation was introduced to encourage manufacturers to create more energy-efficient products and it covers all products that consume energy during their lifetimes, including energy used during production and at the point of disposal.

The ERP assessors assigned a rating of "A" when testing the Glow Worm Energy 12kW.

Is there a warranty on the Glow Worm Energy 12kW system boiler if it breaks down?

You receive a parts and labour warranty of 2 years with the Glow Worm Energy 12kW boiler.
