Glow worm Essential 24 Combi Gas boiler frequently asked questions

What kind of boiler is the Glow Worm Essential 24 - standard, combi or system?

The Glow Worm Essential 24 is a combi boiler you may wish to consider if you want this particular type of boiler for your house or flat.

A combi boiler could be a better choice than a standard boiler if space is at a premium in your home. Combi boilers draw water directly from the mains supply and heat it instantly, removing the need for a hot water cylinder and a cold water tank.

Water is heated on demand and then distributed directly to your taps and showers. This means that combi boilers use less fuel and so reduce your gas bills.

The main disadvantage to combi boilers is that they can only heat a limited volume of water at any given time. If more than one tap or shower is in use, the hot water supply to both could be restricted and both the water pressure and temperature will drop.

Should I install a Glow Worm Essential 24 combi 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 Essential 24 combi outputs at a maximum of 24 kW, so which types of property would this Glow worm Essential 24 Combi boiler be appropriate for?

Most Gas Safe engineers would suggest that the most suitable type of property for installing a Glow Worm Essential 24 combi boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.

Please remember too that all combi boilers draw water from the mains - they have no storage tanks. Combis heat the water from the mains on demand and then send it to wherever it's needed in the house, like a radiator, a bathroom or a kitchen.

The speed at which it can do this is called the "flow rate", which is measured in litres per minute. If you have a lot of radiators and bathrooms in your home and multiple people are regularly trying to use the hot water at one time, such as in the morning or evening, you'll need a combi with a high flow rate. This Glow worm Essential 24 Combi boiler's flow rate is 12 L/m.

However, it's not that simple. Combis can only draw water from the mains at the speed it's delivered. If the flow rate of the local water supply is 11l/m, you shouldn't purchase a boiler with a flow rate of 17l/m because it will never be able to use that extra capacity.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


What size is a Glow Worm Essential 24 boiler?

The Glow Worm Essential 24 measures TBC mm high and TBC mm wide by a depth of TBC mm.

Is the Glow Worm Essential 24 condensing or non-condensing?

This Glow Worm Essential 24 is a condensing gas boiler - we always recommend that clients choose the latest condensing models to benefit from the technology, which continues to improve year after year.

Condensing boilers capture the heat still present in flue exhaust gases and water vapour condensation, processing them through a secondary heat exchanger to, among other tasks, heat colder water returning from your radiators.

By selecting a modern condensing boiler, you'll save money on your gas bills as well as benefitting the wider environment.

Is the Glow Worm Essential 24 combi environmentally friendly?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

Would choosing the Glow Worm Essential 24 combi be an environmentally-friendly choice? If so, let's look at its performance figures.

All boilers manufactured after April 2018 in the UK must be rated as an “A” on the SEDBUK grading system, subject to a minimum energy efficiency rating of 92% or above. Before that, the minimum rate was 88% - boilers with an energy efficiency of 88% or 89% were given a “B” rating. Boilers scoring 90% or more were given an "A" rating.

The energy efficiency rating for a boiler describes the amount of energy it uses and how much goes to waste in operation.

The Glow Worm Essential 24 has an efficiency rating of 89.3% with a SEDBUK grade of "B".

What is the warranty period on a Glow Worm Essential 24 combi boiler?

You receive a parts and labour warranty of 3 years with the Glow Worm Essential 24 boiler.

Glow worm Essential 24 Combi Gas boiler frequently asked questions

What type of boiler is Glow Worm’s Essential 24 - system, regular or combi?

If you’re looking for a combi boiler for your house or flat, you may wish to the consider the Glow Worm Essential 24.

Traditional boilers need one or more large tanks to work - one to heat and keep water warm for immediate use and the other to store water intended for heating later. Finding space for these large tanks is difficult in British residential property - remember that our houses and flats are among the smallest in the world. This is the problem that combi boilers were designed to solve when they were introduced in the 1970s.

Combi boilers don't need a tank - instead, they instantly heat water drawn from the mains using technology inside the boiler. This hot water is then distributed immediately to your taps or radiators on demand.

The biggest disadvantage to combi boilers is that they have a maximum capacity for heating water, meaning that they work best when only one point within a household wants hot water. For example, if someone is taking a shower and another person uses a hot water tap at the same time, the water pressure, volume and temperature to both points drops.

Is a Glow Worm Essential 24 combi boiler suitable for my house or apartment?

You should make sure that the boiler you install in your property 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 has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your gas bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Glow Worm Essential 24 combi's output at 24 kW, which types of property would this Glow worm Essential 24 Combi boiler be most appropriate for?

A PlumbProud heating engineer would recommend that this Glow worm Essential 24 Combi boiler is suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

With all combi boilers, you need to consider the "flow rate" as well as the output rate when making your decision.

Like all combi boilers, the Glow Worm Essential 24 draws water from the mains. It instantly heats that water and then distributes it to the parts of your home which need it - taps, radiators, bathrooms, and so on. This Glow worm Essential 24 Combi boiler's flow rate is 12 L/m.

There is no benefit to purchasing a boiler with a high flow rate if the local water pressure is not that good - a high flow rate doesn't mean that your combi can draw more water from the mains.

In addition, if you live in a home with a large number of radiators and more than one bathroom and if more than one person regularly wants to use hot water at a time, a combi boiler may struggle to provide enough water at a hot enough temperature.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


What size is the Glow Worm Essential 24 boiler?

The Glow Worm Essential 24 measures TBC mm tall, TBC mm wide, and TBC mm deep.

Is the Glow Worm Essential 24 a condensing or non-condensing boiler?

The Glow Worm Essential 24 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 choosing the Glow Worm Essential 24 combi boiler environmentally friendly?

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

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.

Let's take a closer look at whether installing a Glow Worm Essential 24 combi would be a good choice for the environment.

All boilers manufactured and supplied in the UK are assigned two energy efficiency ratings. By law, they must achieve a SEDBUK "A" rating subject to a minimum efficiency level of 92%. Prior to that, the minimum was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90% and above an "A" grade).

The ratings awarded to the Glow Worm Essential 24 are 89.3% with a SEDBUK rating of "B".

Does a Glow Worm Essential 24 combi boiler come with a warranty period?

The Glow Worm Essential 24 boiler comes with a parts and labour warranty lasting 3 years.
