Glow worm Energy 35kW Combi Gas boiler frequently asked questions

Is the Glow Worm Energy 35kW boiler a standard, combi or system model?

Glow Worm’s Energy 35kW is one you might consider if you’re looking for a combi boiler for your house or flat.

In the past, most boilers needed one or more storage tanks to operate - one to store warm water and the other for storing water to be heated later. But storage tanks are problematic in properties where space is at a premium and particularly where there is no loft. Many properties in the UK are small and so manufacturers introduced combi boilers in the 1970s to eliminate the need for tanks.

With a combi boiler, the hot water for your radiators and taps is delivered on demand. The boiler instantly heats water it draws directly from the mains internally. It then distributes the heated water around your home at mains pressure as you need it.

It is important to bear in mind that, while combi boilers have many benefits, they can only heat a certain volume of water at any given time. This means that, if you run a shower at the same time as someone else is doing the washing up in the kitchen, the volume of water passing to each point will drop, causing a fall in pressure.

Should I choose a Glow Worm Energy 35kW combi 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 - its "output".

The output rate tells you how much energy your boiler has to use to provide you and your family with hot water and central heating. A higher output rate means that it can heat greater volumes of water.

Please be aware, though - if you choose a boiler whose output is too low, the water in your radiators and coming from your taps may not be warm enough. Conversely, if you choose a boiler with too high an output, you'll pay more for gas than is necessary.

The Glow Worm Energy 35kW combi boiler has an output level of 35 kW, so which types of property would it be appropriate for?

A heating engineer would recommend that this Glow worm Energy 35kW Combi boiler would provide adequate heating and hot water for larger properties including detached homes with up to 15 or more radiators and two or more bathrooms.

If you are considering installing a combi boiler in your home, you need to consider the flow rate as well as the output rate.

The flow rate is the volume of water (measured in litres per minute) that your boiler can instantly heat up and send around the home. The more demand in your home for water at the same time (for example, two people taking showers in different bathrooms), the higher the flow rate you'll need.

However, the actual flow rate your boiler can deliver is also determined by your mains water pressure. If you choose a boiler with a flow rate of 16l/m but the mains water pressure is 12l/m, your boiler will only perform to 12l/m. This Glow worm Energy 35kW Combi boiler's flow rate is 14 L/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.


What is the size of the Glow Worm Energy 35kW?

The Glow Worm Energy 35kW's dimensions are 700 mm [H] x 390 mm [W] x 280 mm [D].

Is the Glow Worm Energy 35kW a non-condensing or condensing boiler?

The Glow Worm Energy 35kW is a condensing gas boiler - we strongly recommend that you choose one of the latest condensing models if possible.

With a condensing boiler, you save money on your gas bills because your boiler captures and recycles the heat present in the flue exhaust gases and water vapour condensation for re-use, meaning they operate far more economically and efficiently.

Is the Glow Worm Energy 35kW combi boiler environmentally friendly?

With environmental issues in the spotlight, more and more homeowners are becoming concerned about how they heat their homes and how much they're contributing towards combatting climate change.

As much as 14% of the UK’s greenhouse gas production derives from our domestic central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in Britain's largest cities.

Will choosing to install a Glow Worm Energy 35kW combi in your home help the environment? Let's review the figures.

All boilers manufactured and supplied in the UK must achieve an energy efficiency rating of at least 92% (an "A" SEDBUK grade). This is higher than the previous 88%, which was a legal requirement prior to April 2018.

The energy efficiency rating is used to work out how much energy a boiler both uses and wastes when it's switched on and working correctly - its standard functioning and operation.

The Glow Worm Energy 35kW is rated as 89.2% energy efficient, equivalent to a "B" SEDBUK rating.

The Energy Related Products Directive (ERP) intends to reduce the amount of energy consumed by individual products over their entire lifetime, from the initial manufacturing process to final disposal and at all points in between.

The legislation is designed to encourage manufacturers to create products that are more environmentally friendly and which result in a reduction in harmful gas emissions.

The ERP rating for the Glow Worm Energy 35kW is "A" for heat and "A" for hot water production.

What length of warranty does the Glow Worm Energy 35kW come with?

On the Glow Worm Energy 35kW, the manufacturer offers a parts and labour warranty of 2 years.

Glow worm Energy 35kW Combi Gas boiler frequently asked questions

What type of boiler is the Glow Worm Energy 35kW?

The Glow Worm Energy 35kW is a combi boiler you may wish to consider if you want this type of boiler for your house or flat.

Traditional boilers often have up to two tanks that either store heated water or water to be heated later. Boiler manufacturers introduced combi boilers in the 1970s to avoid the need for those big tanks. Combi boilers allow homeowners to benefit from the reliable central heating and hot water level they want but without having to give up so much space within their properties - remember that homes in the UK are among the smallest in the developed world.

Your taps and radiators get the hot water they need with a combi boiler. Combi boilers draw cold water direct from the mains which is then heated instantly on demand and distributed to your radiators and taps.

However, combi boilers cannot heat very large volumes of water, which is their main disadvantage. So, for example, when someone wants to take a shower while another person wants to use a hot water tap to do the dishes, water pressure and quantity to both points decreases.

Should I install a Glow Worm Energy 35kW combi boiler in my house or apartment?

It's best to choose a boiler whose size or "output" is right for your home.

The more hot water and heat you want, the higher the output level of your boiler should be. Output is measured in kilowatts and it describes the maximum level of power your boiler has to heat water.

If your output level is too low, your boiler will not have the power it needs to get your water as hot as you want it, particularly when there's a lot of demand for it. Choose a boiler whose output level is too high and you'll have all the hot water you need but will be paying too much for it through higher gas bills.

Which types of property would this Glow worm Energy 35kW Combi boiler be appropriate for given its output of 35 kW?

A PlumbProud Gas Safe engineer would recommend that this Glow worm Energy 35kW Combi boiler is suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

With all combi boilers, the "flow rate" (measured in litres per minute) is as important a consideration as output rate when choosing which model to go for. This Glow worm Energy 35kW Combi boiler's flow rate is 14 L/m.

Like all combi boilers, the Glow Worm Energy 35kW 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.

However, the water in the mains pipe that feeds your boilers has its own flow rate - normally between 10 and 12l/m. So if you choose a combi with a flow rate of 14l/m but local water pressure is equivalent to 11l/m, your boiler will actually operate at 11l/m - below its capacity.

In addition, if different family members want hot water at the same time (like for regular morning and evening showers) and your boiler has to provide hot water to your radiators at the same time, a combi boiler may not be suitable.

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.


The size of the Glow Worm Energy 35kW

The size of the Glow Worm Energy 35kW boiler is 700 mm tall, 390 mm wide, and 280 mm deep.

Glow Worm Energy 35kW – non-condensing or condensing?

We recommend that, if possible, you select one of the very latest condensing gas boilers on the market like the Glow Worm Energy 35kW.

Condensing boilers are better for the environment because they capture and recycle the heat still present in flue exhaust gases and water vapour condensation for re-use, meaning lower greenhouse gas emissions.

They're also a lot cheaper to run meaning that, if you're replacing a very old and inefficient boiler, the savings on your gas bill over 5-10 years add up to more than you pay for the boiler itself.

Is the Glow Worm Energy 35kW combi an energy-efficient boiler?

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

The heating of our homes accounts for 14% of the UK's greenhouse gas emissions. Especially in the big cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Will choosing to install a Glow Worm Energy 35kW combi in your home help the environment? Let's review the figures.

The energy efficiency rating of the Glow Worm Energy 35kW is 89.2% with a SEDBUK band rating of "B".

Energy efficiency tests record how much energy is wasted on non-core functions during an operation.

By law, all boilers manufactured and supplied in the UK must have a minimum energy efficiency performance level of 92% (equivalent to a SEDBUK "A" grade). Up to April 2018, the minimum performance level was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90%+ an "A" grade).

The aim of the Energy Related Products (ERP) Directive is to reduce the harmful gas emissions created during a product’s manufacture and active end use right through to its disposal.

The ERP rating for the Glow Worm Energy 35kW is "A" for heat and "A" for water.

If the Glow Worm Energy 35kW breaks down, will I be covered by the warranty?

The Glow Worm Energy 35kW boiler is covered by a parts and labour warranty of 2 years.
