Glow worm Energy 12kW heat only Gas boiler frequently asked questions

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

The Glow Worm Energy 12kW is a gas heat only boiler.

If your home has more than one bathroom or you have a large family which uses a lot of hot water, a heat only boiler (sometimes called a regular boiler, a conventional boiler or a standard boiler) is likely to be the best option for you. Heat only boilers require both a hot water or immersion cylinder and a cold water tank. Once the water in the cylinder is heated, you can use this hot water throughout the day and it can feed multiple taps and showers at the same time.

This is in contrast to a combi boiler which can only heat a limited amount of water at any one time. This can cause a problem if two or more taps and showers are being used simultaneously as the temperature, pressure and volume to all points will drop.

Heat only boilers allow you to program the times that you wish heat and hot water to be available. However, if you forget to do this and the immersion cylinder is empty, you may have to wait up to an hour before hot water becomes available again.

If your property already has a water tank and cylinder, it will nearly always be cheaper to replace like for like and not choose a different type of boiler. In addition to new pipework, you may need to replace older radiators that may be unable to cope with the higher water pressure delivered by other types of boiler.

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

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

Boiler output is measured in kilowatts and tells you how much power a boiler can use to heat the water your taps, showers and radiators need. The higher the output, the more power it has.

When choosing a boiler, you should choose one that can cope with the peak demand for hot water in your home and not just your typical usage.

If its output is too low, sometimes your hot water will not be hot enough, but if your boiler's output is too high for your needs, your gas bills will go up and not down.

The output of the Glow Worm Energy 12kW heat only is 12 kW, so which types of property would this Glow worm Energy 12kW heat only boiler be an appropriate choice for?

A PlumbProud heating engineer would recommend that this Glow worm Energy 12kW heat only boiler is suitable for smaller homes and apartments with up to 10 radiators and one bathroom.


Glow Worm Energy 12kW dimensions

The Glow Worm Energy 12kW measures 700 mm tall, 375 mm wide, and 280 mm deep.

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

The Glow Worm Energy 12kW 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.

How energy efficient is the Glow Worm Energy 12kW heat only boiler?

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

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 choosing the Glow Worm Energy 12kW heat only boiler be an environmentally friendly decision? Here's what the figures say.

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 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 12kW has an ERP rating of "A".

Is this Glow Worm Energy 12kW heat only covered by a warranty?

The parts and labour warranty on the Glow Worm Energy 12kW lasts for 2 years.

Glow worm Energy 12kW heat only Gas boiler frequently asked questions

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

The Glow Worm Energy 12kW boiler could be suitable for your house or flat if you are looking for a new heat only boiler.

Heat only boilers are sometimes called standard boilers, regular boilers or conventional boilers but they are actually the same thing. For a heat only boiler, you'll need to find space for both a cold-water tank and an immersion hot water cylinder - most households choose the attic for the former and a landing cupboard or airing cupboard for the latter. The immersion cylinder is the part of the system that keeps your hot water warm.

You program your boiler to provide you with the hot water you want at certain times, such as when you want to have a bath or a shower. However, if you don't remember to program your boiler, you'll have to wait for it to heat up if the hot water has run out.

A regular boiler is the most suitable choice if you have a larger family or if there is more than one bathroom in your home - the more popular combi boilers do not work well in homes where there is high and often simultaneous demand for hot water.

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

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 12kW heat only is 12 kW, so which types of property would this Glow worm Energy 12kW heat only boiler be appropriate for?

Most experienced heating engineers would likely recommend that, at this level of output, this Glow worm Energy 12kW heat only boiler would be a suitable choice for smaller homes and apartments with up to 10 radiators and one bathroom.


What size is the Glow Worm Energy 12kW boiler?

The Glow Worm Energy 12kW is 700 mm tall, 375 mm wide, and 280 mm deep.

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

We recommend that, if possible, you select one of the very latest condensing gas boilers on the market like the Glow Worm Energy 12kW.

Condensing boilers are better for the environment because they capture and recycle the heat still present in flue exhaust gases and water vapour condensation for re-use, meaning lower greenhouse gas emissions.

They're also a lot cheaper to run meaning that, if you're replacing a very old and inefficient boiler, the savings on your gas bill over 5-10 years add up to more than you pay for the boiler itself.

Is the Glow Worm Energy 12kW heat only boiler rated as environmentally friendly?

With more and more of us concerned about environmental issues and climate change, how we heat our homes has become an important issue to many homeowners.

Around 14% of the greenhouse gases produced in the UK is a result of our central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in some of our largest cities.

Would installing the Glow Worm Energy 12kW heat only in your home be an environmentally friendly decision? Let's look closely at the figures.

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 ERP, short for the Energy Related Products Directive, is a European directive aimed at encouraging manufacturers to create products that are environmentally friendlier at all stages, including during manufacturing, when the product is in active use, and right through to the point of final disposal.

The Glow Worm Energy 12kW has a rating of "A" .

Does the Glow Worm Energy 12kW heat only boiler come with a warranty?

The parts and labour warranty offered with this Glow worm Energy 12kW heat only boiler covers you for 2 years.
