Glow worm Essential 28 Combi Gas boiler frequently asked questions

What type of boiler is the Glow Worm Essential 28 - regular, system or combi?

Suitable for a house or a flat, the Glow Worm Essential 28 combi boiler is worth considering if you want a combi boiler.

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 28 combi boiler the right choice for my house or apartment?

Selecting the right boiler for your property means selecting 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".

The output of a boiler is measured in kilowatts. The output level determines the maximum power a boiler can use in heating the water needed for the baths, showers, taps and radiators in your home.

It's important to choose a boiler with an appropriate level of output for your property. Your boiler should be able to cope with periods of peak demand in your property and not just your average usage.

An output rate that is too low will result in an inadequate supply of hot water, while an output that is too high will mean the boiler will cost more to run than is necessary.

The output of the Glow Worm Essential 28 combi is 28 kW kilowatts, so which types of property would this be appropriate for?

Most experienced boiler engineers would recommend that this Glow worm Essential 28 Combi boiler would be suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

When choosing a combi boiler for your home, you need to think about "flow rates" as well as output rates. This Glow worm Essential 28 Combi boiler's flow rate is 12 L/m.

This indicates the maximum volume of hot water (measured in litres per minute) that your boiler can heat then distribute to your taps, showers and radiators at any one time. The greater the demand for hot water in your home, the higher the flow rate you will require.

However, all combi boilers like the Glow Worm Essential 28 draw water directly from the mains and heat it instantly.

This means that they can only heat and distribute water at the rate it enters the property (the "mains pressure" rate). For example, if your mains pressure is 11 litres per minute, this will be the highest flow rate you can achieve even if your boiler's flow rate is 17l/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.


Glow Worm Essential 28 - size in millimetres

The Glow Worm Essential 28 is TBC mm tall, TBC mm wide, and TBC mm deep.

Is the Glow Worm Essential 28 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 Essential 28 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.

How energy efficient is the Glow Worm Essential 28 combi boiler?

With more and more people concerned about climate change, how we heat our homes and the damage it does to the environment is increasingly being questioned by British 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 choosing the Glow Worm Essential 28 combi boiler be an environmentally friendly decision? Here's what the figures say.

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 28 has an efficiency rating of 89.3% with a SEDBUK grade of "B".

Does the Glow Worm Essential 28 combi boiler come with a warranty?

The parts and labour warranty on the Glow Worm Essential 28 lasts for 3 years.

Glow worm Essential 28 Combi Gas boiler frequently asked questions

Is the Glow Worm Essential 28 a system boiler, a combi boiler or a regular boiler?

Suitable for a house or a flat, the Glow Worm Essential 28 combi boiler is worth considering if you want a combi boiler.

One of the reasons the combi boiler was introduced to Britain in the 1970s was because residential properties are among the smallest in the world. More traditional boilers require one or more large tanks to be stored around the home to function.

A combi boiler is a self-contained unit that draws water from the mains then heats and distributes it instantly and on demand - no tanks are needed.

They are the most popular type of boilers in the UK and offer only one major disadvantage - there is a maximum volume of water that can be heated at any one time. If that limit is exceeded by, for example, two people using a hot water tap at the same time, there will be a drop in water pressure, temperature and volume to both taps.

Is a Glow Worm Essential 28 combi the right boiler for my house or flat?

Selecting the right boiler for your property means selecting 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".

The output of a boiler is measured in kilowatts. The output level determines the maximum power a boiler can use in heating the water needed for the baths, showers, taps and radiators in your home.

It's important to choose a boiler with an appropriate level of output for your property. Your boiler should be able to cope with periods of peak demand in your property and not just your average usage.

An output rate that is too low will result in an inadequate supply of hot water, while an output that is too high will mean the boiler will cost more to run than is necessary.

The output of the Glow Worm Essential 28 combi is 28 kW kilowatts, so which types of property would this be appropriate for?

A Gas Safe boiler installer would say that this Glow worm Essential 28 Combi boiler's level of output makes it suitable for installing in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

You also need to choose a combi boiler with the right flow rate for where you live.

A combi boiler's flow rate is the maximum volume of water (measured in litres per minute) that it can heat and distribute to your radiators, taps and showers at the same time. This Glow worm Essential 28 Combi boiler's flow rate is 12 L/m.

However, combi boilers like the Glow Worm Essential 28 draw water directly from the mains and heat it instantly.

If your mains pressure is 12 litres per minute, your boiler can only heat and distribute hot water at a rate of 12 litres per minute even if it has a higher flow rate.

Combi boilers also struggle when multiple people in your home want to use hot water at the same time - for example, someone running the hot water tap in the kitchen and two people wanting to shower in separate bathrooms.

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 28 boiler?

The Glow Worm Essential 28 is TBC mm in height, TBC mm in width and TBC mm in depth.

Glow Worm Essential 28 – condensing or non-condensing?

The Glow Worm Essential 28 is a condensing boiler – we recommend to all clients that they choose the very latest condensing boilers because their efficiency continues to improve year after year.

Condensing boilers recycle heat from both water vapour condensation and flue exhaust gases via a secondary heat exchanger. With this heat, it performs other tasks like warming up colder water returning from your radiator without having to use more gas.

You will save money on your gas bills every year by choosing a condensing boiler as well as benefitting the environment.

Is the Glow Worm Essential 28 combi environmentally friendly?

With more and more people concerned about climate change, how we heat our homes and the damage it does to the environment is increasingly being questioned by British homeowners.

In the UK, central heating systems account for 14% of greenhouse gas production. Gas boilers in particular are responsible for emissions of dangerous nitrogen dioxide in British cities.

Would installing a Glow Worm Essential 28 combi boiler in your home help combat climate change? What do the figures suggest?

Boilers manufactured or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to this, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The Glow Worm Essential 28 has been given a rating of 89.3% for energy efficiency, equivalent to a SEDBUK "B" rating.

Will I be covered if the Glow Worm Essential 28 combi breaks down?

Parts and labour charges incurred during a repair on the Glow Worm Glow Worm Essential 28 boiler are covered by a 3 year warranty.
