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

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

If you’re looking for a heat only boiler for your house or flat, then the Glow Worm Energy 25kW is one you may wish to consider.

Heat only boilers (often referred to as standard boilers, regular boilers or conventional boilers) need both a hot water cylinder and a cold water tank to work. The hot water cylinder heats and keeps warm the water you need and is normally installed in either a utility room or attic. The cold water tank holds water which it passes to the hot water cylinder depending on how you've programmed your boiler.

When you program a heat only boiler, you set the times and days when you want central heating and hot water to be available. However, if you don't remember to program your boiler and there's no water left in the hot water cylinder, you may have to wait up to an hour for hot water to come out of your taps.

Heat only boilers can cope with the demand for hot water from multiple taps and sources around your home simultaneously. That's why they're better for larger homes than combi boilers - combi boilers struggle when more than one hot tap is turned on. This is because they have a maximum capacity of water they can heat and distribute at any one time, meaning water pressure, temperature and volume to each tap drops.

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

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

Most experienced boiler engineers would recommend that this Glow worm Energy 25kW heat only boiler would be suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


What size is the Glow Worm Energy 25kW boiler?

The Glow Worm Energy 25kW is 700 mm tall, 375 mm wide, and 280 mm deep in size.

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

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 rated as environmentally friendly?

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on climate change.

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.

Would choosing a Glow Worm Energy 25kW heat only help the environment? Let’s see what the performance figures suggest.

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 25kW was given an efficiency rating of 89.2% and a SEDBUK grading of "B".

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".

Am I covered if the Glow Worm Energy 25kW heat only boiler breaks down?

The manufacturer offers a parts and labour warranty of 2 years on the Glow Worm Energy 25kW boiler to new customers.

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

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

The Glow Worm Energy 25kW is worthy of consideration if you're looking for a heat only boiler for your flat or house.

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 the Glow Worm Energy 25kW heat only boiler suitable for 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 25kW heat only has an output of 25 kW, so which types of property would this Glow worm Energy 25kW heat only boiler be appropriate for?

Most experienced boiler engineers would recommend that this Glow worm Energy 25kW heat only boiler would be suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


Making space for the Glow Worm Energy 25kW

The dimensions of the Glow Worm Energy 25kW are 700 mm [H] x 375 mm [W] x 280 mm [D].

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

Because of their increased energy efficiency, we recommend to all customers that they select one of the latest condensing boilers. Condensing boilers capture the heat from water vapour condensation and flue exhaust gases and recycle that heat to warm water entering the boiler (for example, from your radiators).

The Glow Worm Energy 25kW is a condensing gas boiler and choosing this model will result in a likely substantial reduction in your fuel bills, particularly if you're replacing an older, inefficient, non-condensing boiler.

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

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

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.

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

All new British boilers must perform to a legal minimum energy efficiency of 92% (a low to good SEDBUK "A" rating). Prior to April 2018, the target was 88% (86-90% = SEDBUK "B" and 90%+ = SEDBUK "A").

Efficiency ratings are intended to let consumers know how much energy a boiler uses in its day-to-day activities and how much energy goes to waste.

The Glow Worm Energy 25kW was awarded an efficiency rating of 89.2%, equivalent to a SEDBUK grade of "B".

Energy-efficient boilers help the environment as they require less fuel and emit fewer harmful gases. In 2015, the EU introduced the Energy Related Products Directive (ERP) with the aim of ensuring that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

This legislation aims to conserve energy at all life cycle stages, from initial production through to actual use by a customer and up to the point of disposal.

The Glow Worm Energy 25kW has been given an ERP rating of "A".

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

The Glow Worm Energy 25kW is supplied with a parts and labour warranty of 2 years.
