Glow worm Essential 24 Combi Gas boiler frequently asked questions

Is the Glow Worm Essential 24 a regular, combi or system boiler?

The Glow Worm Essential 24 is an option you may wish to consider if you’re looking for a combi boiler for your house or flat.

Traditional boilers consist of one or more large tanks that take up a lot of space in people's homes. One tank heats water and keeps it warm and the other stores water for heating later.

In contrast, a combi boiler is a much smaller stand-alone unit. Instead of requiring water tanks, it draws cold water from the mains. When hot water is needed for a shower, for the washing up, or the dishwasher, the cold water is heated instantly by the boiler and distributed to where it is needed.

The main disadvantage of combi boilers is that there is a limit to how much water they are capable of heating at the same time. For instance, water pressure, volume and temperature will be adversely affected if more than one individual in the home needs hot water at the same time.

Is a Glow Worm Essential 24 combi the right boiler for my house or flat?

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 Essential 24 combi is 24 kW, so which types of property would this Glow worm Essential 24 Combi boiler be appropriate for?

Most boiler engineers would recommend that a boiler with this output level would be most suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

Flow rates are important when choosing a combi boiler as well as output rates.

A combi boiler's flow rate (measured in litres per minute) describes how much water it can instantly heat then distribute to the taps and radiators in your home - you will need to factor this into your decision on a new combi boiler. This Glow worm Essential 24 Combi boiler's flow rate is 12 L/m.

If you have a lot of radiators and bathrooms in your home and there's lots of demand within your household for hot water at the same time (like morning or evening showers and baths), you'll need a boiler with a high flow rate.

However, it's not quite that simple. If your local mains water pressure is low, you're not going to gain any benefit from choosing a combi boiler with a high flow rate because that higher flow rate doesn't mean it can draw more water from the mains pipes.
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 is TBC mm tall, TBC mm wide, and TBC mm deep in size.

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

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.

In the UK, central heating is responsible for 14% of greenhouse gas production. Domestic gas boilers emit large quantities of nitrogen dioxide in British cities.

Would choosing the Glow Worm Essential 24 combi boiler be an environmentally friendly decision? Here's what the figures say.

The energy efficiency rating for a boiler describes the amount of energy it uses and wastes during operation and there are two different ways to measure it.

All boilers manufactured and supplied in the UK must have a SEDBUK rating of “A” subject to a minimum energy efficiency score of 92% or above. Before April 2018, the minimum energy efficiency score was 88% (88/89% = "B" SEDBUK rating, 90%+ = "A" SEDBUK rating).

The Glow Worm Essential 24 scored an efficiency rating of 89.3% and a SEDBUK band rating of B.

What is the warranty period for the Glow Worm Essential 24?

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

Glow worm Essential 24 Combi Gas boiler frequently asked questions

Is the Glow Worm Essential 24 a regular, combi or system boiler?

You may wish to consider installing the Glow Worm Essential 24 if you are looking for a combi boiler for your house or flat.

Traditionally, most boilers required you to find space in your property for one or more large storage tanks. These tanks would either keep water warm or hold it in reserve for later heating. Manufacturers originally introduced combi boilers to offer homeowners the same level of warmth and hot water without taking up as much space – remember that the UK has some of the smallest homes in the Western world.

With a combi boiler, the hot water needed for your radiators and taps is provided on demand. Water from the mains passes through your combi boiler and the technology within it instantly heats the cold water. It then distributes that hot water around your home.

The biggest drawback for combi boilers is that they have a maximum capacity in volume for heating water. This means that if someone wants to use the shower while another person wants to use a hot water tap, the amount of water reaching each point falls, resulting in a drop in water pressure.

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

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 Essential 24 combi's output is 24 kW, so which types of property would this Glow worm Essential 24 Combi boiler be appropriate for?

A PlumbProud boiler 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 combi boilers, you need to consider the flow rate as well as the output rate. The flow rate (shown in litres per minute) measures how much water your boiler can draw from the mains which it then instantly heats and distributes to your taps and radiators.

However, a high flow rate is of little to no value if your local water pressure is low. If your local mains water pressure is 10l/m and your flow rate is 12l/m, your boiler will only be able to process 10l/m.

If you live in an area with high water pressure but your household has multiple bathrooms and/or radiators and many members of your household want to use hot water at the same time (like morning or evening baths or showers), it's unlikely that you'll be able to find a combi with a high enough flow rate.

As an indication, a power shower needs about 10 litres of water per minute, whereas the flow rate of this Glow worm Essential 24 Combi boiler is 12 L/ml/m.

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.


How large is a Glow Worm Essential 24 boiler?

The Glow Worm Essential 24 is TBC mm high by TBC mm wide by TBC mm deep.

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

The Glow Worm Essential 24 is a condensing gas boiler - we strongly suggest that you choose either this model or a recently released model if at all possible.

A condensing boiler captures and recycles the warmth present in flue exhaust gases and water vapour condensation created by the burning of gas to warm up the water coming back into your boiler - for example, from your radiators.

Condensing boilers cost less to run (lower gas bills) and are better for the environment.

Is the Glow Worm Essential 24 combi good for the environment?

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.

Central heating systems are responsible for 14% of greenhouse gas emissions in the UK. You may also be aware that the gas boilers we use emit dangerous nitrogen dioxide in large volumes in the bigger British cities.

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 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".

How long is the warranty offered by the manufacturer for the Glow Worm Essential 24 boiler?

The parts and labour warranty on the Glow Worm Essential 24 covers all repair-related costs for 3 years while the heat exchange warranty covers you for [Heat Exchange Warranty] years.
