Glow worm Energy 12kW System Gas boiler frequently asked questions

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

You may wish to consider installing the Glow Worm Energy 12kW if you are looking for a system boiler for your house or flat.

System boilers are suitable for homes with a higher-than-average demand for central heating and water - for example, larger homes and larger families.

Tell the boiler when you want hot water using the control panel - it draws water from the mains, heats it and keeps it warm throughout the day in the hot water cylinder. As long as you remember to tell the boiler when you want hot water, you have a big enough cylinder, and there's not an unusually high demand for water on a particular day, you should have hot water whenever you need it.

System boilers do not require a cold water storage tank either, unlike heat only boilers, meaning they're cheaper, quicker and easier to install.

Is the Glow Worm Energy 12kW system boiler a suitable choice for my property?

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 12kW system's output at 12 kW, which types of property would this Glow worm Energy 12kW System boiler be most 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.


Glow Worm Energy 12kW size

The Glow Worm Energy 12kW's dimensions are 700 mm [H] x 390 mm [W] x 280 mm [D].

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

The Glow Worm Energy 12kW 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 12kW system a good choice for the environment?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important 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 choosing a Glow Worm Energy 12kW system help in the fight against climate change? What do the performance statistics suggest?

In the UK, by law, all boilers manufactured since April 2018 must have a SEDBUK “A” rating and operate to a minimum level of 92% energy efficiency. Prior to this, the minimum was 88% – 88/89% would score a "B" and 90% or more an "A" on the SEDBUK scale.

The energy efficiency rating measures the amount of energy a boiler consumes when it's in use and how much it loses on non-core operations.

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

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.

If the Glow Worm Energy 12kW breaks down, will I be covered by the warranty?

Glow Worm’s Energy 12kW boiler includes a parts and labour warranty of 2 years.

Glow worm Energy 12kW System Gas boiler frequently asked questions

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

Glow Worm’s Energy 12kW is one you might consider if you’re looking for a system boiler for your house or flat.

System boilers work similarly to heat only boilers in that they need a hot water cylinder (usually installed in the home’s airing or landing cupboard) to operate. Unlike heat only boilers though, system boilers don’t require a separate cold-water tank, making them a more suitable choice in homes with little or no attic space or where homeowners are planning a loft conversion in the future.

Instead of large cold-water tanks, system boilers use built-in circulating pumps to provide hot water to your taps and radiators. This makes them easier to install from scratch as they have one less component to find room for and fit.

System boilers need to be programmed with the time you want heat and hot water - they don't offer hot water on demand like combi boilers.

Is a Glow Worm Energy 12kW system the right boiler for my house or flat?

Whether this Glow worm Energy 12kW 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 12kW system is 12 kW, so which types of property would this model be appropriate for?

An experienced heating engineer would say that this Glow worm Energy 12kW System boiler's level of output makes it a suitable installation for smaller homes and apartments with up to 10 radiators and one bathroom.


How large is the Glow Worm Energy 12kW?

The Glow Worm Energy 12kW stands at 700 mm tall, 390 mm wide and 280 mm deep.

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

We recommend the Glow Worm Energy 12kW as it is a modern condensing gas boiler from a trusted manufacturer with a reputation for supplying highly energy-efficient boilers.

Condensing boilers capture the heat still present in water vapour condensation and flue exhaust gases and recycle it back into the heating system. With this extra energy, your boiler can, among other tasks, reheat colder water coming back from your radiators without having to burn more gas.

Condensing boilers significantly reduce your quarterly gas costs and they're better for the environment.

Is the Glow Worm Energy 12kW system boiler an environmentally friendly choice?

How we heat our homes is an issue which many homeowners worry about as the world combats climate change and environmental damage.

Central heating creates 14% of the UK’s greenhouse gases. And in Britain's larger cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Would installing a Glow Worm Energy 12kW system boiler in your home be a green choice? 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 12kW was awarded an efficiency rating of 89.3% with a SEDBUK band rating of "B".

The Energy Related Products Directive (ERP) is European legislation that applies to all products which use or consume energy during their lifespan - this includes during the manufacturing process and when they're in use, right through to the point of final disposal.

The aim is to encourage manufacturers to create new products that are kinder to the environment and which create fewer harmful gas emissions.

The Glow Worm Energy 12kW has an ERP Heat rating of "A".

If the Glow Worm Energy 12kW system boiler breaks down, am I covered?

The Glow Worm Energy 12kW boiler has a warranty covering parts and labour costs for up to 2 years after installation.
