Glow worm Energy 25kW heat only Gas boiler frequently asked questions

Glow Worm Energy 25kW - a regular, combi or system boiler?

The Glow Worm Energy 25kW is a heat only boiler you may wish to consider if you want this particular type of boiler for your house or flat.

If your home has more than one bathroom or you have a large family that 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.

Would the Glow Worm Energy 25kW heat only boiler be suitable 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.

The output rate of a boiler tells you how much power it has available to it for heating the water that comes out of your taps and warms your radiators. A higher output rate means that your boiler has more power at its disposal.

You need to make sure you select a boiler with the right output rate. That's because, if your output rate is too high, then your boiler will have more power than it needs but it will cost too much to run. If the output rate is too low, your water may often not be hot enough.

The Glow Worm Energy 25kW heat only's output is 25 kW, so which types of property would this Glow worm Energy 25kW heat only boiler be appropriate for?

An experienced Gas Safe boiler installer would recommend that, at this level of output, the most suitable type of property for this Glow worm Energy 25kW heat only boiler would be medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


What size is a Glow Worm Energy 25kW boiler?

The Glow Worm Energy 25kW is 700 mm [H] by 375 mm [W] by 280 mm [D] in size.

Is the Glow Worm Energy 25kW condensing or non-condensing?

We strongly recommend that you choose a condensing boiler like the Glow Worm Energy 25kW - the technology is improving every year so the newer the boiler, the better.

A condensing boiler captures and recycles the warmth still present in flue exhaust gases and water vapour condensation into heat, allowing it to perform more efficiently on tasks like heating the colder water returning from your radiators.

They also offer significant annual savings on household gas bills as well as being more environmentally friendly.

Is the Glow Worm Energy 25kW heat only boiler environmentally friendly?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of climate change.

Gas boilers are responsible for dangerous atmospheric levels of nitrogen dioxide emissions in Britain's biggest cities and, overall, 14% of the UK’s greenhouse gases are produced by our domestic central heating systems.

Is the Glow Worm Energy 25kW heat only boiler an environmentally friendly choice for your home? Here’s what the figures say.

By law, the minimum level of energy efficiency for boilers manufactured in the UK is 92%, equivalent to a good SEDBUK “A” rating. Prior to April 2018, the minimum was 88% - boilers whose energy efficiency levels were 88% or 89% were given a "B" rating on the SEDBUK scale and those at 90% or higher were given an "A".

The energy efficiency rating awarded to each boiler indicates the amount of energy that is wasted when in operation.

Following testing, the Glow Worm Energy 25kW was given a 89.2% energy efficiency rating and a SEDBUK grading 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 25kW has an ERP Heat rating of "A".

If the Glow Worm Energy 25kW breaks down, will I be covered by the warranty?

The Glow Worm Energy 25kW boiler has a warranty covering parts and labour costs for up to 2 years after installation.

Glow worm Energy 25kW heat only Gas boiler frequently asked questions

Is the Glow Worm Energy 25kW a system boiler, a combi boiler or a regular boiler?

When looking for a heat only boiler for your house or flat, the Glow Worm Energy 25kW might be a suitable option for you.

Heat only boilers, also known as regular or conventional boilers, need enough space for a hot water cylinder with an immersion heater (usually found in a landing cupboard) and a cold-water tank (usually found in a loft). The hot water cylinder keeps water warm and the cold water tank stores water that it passes to the hot water cylinder when required or programmed to do so.

You control how your heat only boiler works by programming it to heat water and provide central heating at the times and on the dates you choose. But if you forget to set times and dates and your hot water cylinder is empty, you may have to wait up to an hour before you have hot water again in your home.

Heat only boilers are often the best choice for a larger family or a property with multiple bathrooms as, unlike with combi boilers, there is no drop in water pressure, temperature or volume when more than one person wants hot water.

Should I install a Glow Worm Energy 25kW heat only boiler in my home?

You should make sure that the boiler you choose for your property is the right "size". And size doesn't mean its physical dimensions. Size means how much power it has - the "output".

A boiler's output level measures how much power it can use to provide you with the hot water you need for your radiators and taps. If a boiler has a high output rate, it can heat greater volumes of water.

If you choose a boiler with too low an output, you'll find that the water coming out of your taps and in your radiators won't be as hot as you want it to be. Choosing one whose output is too high means you'll pay more than you need to for the gas your boiler needs to work.

The Glow Worm Energy 25kW heat only outputs at a maximum of 25 kW, so which types of property would this Glow worm Energy 25kW heat only boiler be appropriate for?

An experienced PlumbProud heating engineer would recommend that the most suitable type of property for a Glow Worm Energy 25kW heat only would be medium-sized homes and larger apartments containing 10-15 radiators and providing hot water for two bathrooms.


Glow Worm Energy 25kW - size in millimetres

The Glow Worm Energy 25kW is 700 mm [H] by 375 mm [W] by 280 mm [D] in size.

Is the Glow Worm Energy 25kW a condensing or non-condensing boiler?

The Glow Worm Energy 25kW is a condensing gas boiler - where possible, we always recommend to clients that they choose one of the very latest condensing boilers to take advantage of this technology, which improves year after year.

Condensing boilers are more energy-efficient as they capture and recycle the heat contained in flue exhaust gases and water vapour condensation. They then use this heat to perform tasks like warming up colder water returning to the boiler from the radiators.

By choosing a condensing boiler, you'll help the environment as well as save money on your gas bills.

Is the Glow Worm Energy 25kW heat only an energy-efficient boiler?

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

In Britain's bigger cities, gas boilers, in particular, are responsible for dangerous levels of nitrogen dioxide emissions. Overall, 14% of all of the UK’s greenhouse gas production comes from heating our homes.

Would the environmental impact of installing a Glow Worm Energy 25kW heat only in your home be positive? Let's look at the numbers.

Every boiler manufactured and supplied in the UK must have an energy efficiency rating of 92% (SEDBUK “A” rating). These minimums were made law in April 2018 - before that, the minimum energy efficiency rating was 88% (88%/89% = "B" SEDBUK grade, 90%+ = "A" SEDBUK grade).

The Glow Worm Energy 25kW was awarded an efficiency rating of 89.2% and a band rating of "B".

Energy efficiency ratings for boilers describe the amount of energy they use and waste when switched on and working.

The Energy Related Products (ERP) Directive is important European legislation that aims to limit energy use and harmful gas emissions during the manufacturing process, when the product is in use, and after it is disposed of.

For the Glow Worm Energy 25kW, the ERP Heat rating is "A".

Does the Glow Worm Energy 25kW heat only boiler come with a warranty?

Glow Worm offers a parts and labour warranty of 2 years on the Glow Worm Energy 25kW.
