Glow worm Energy 15kW System Gas boiler frequently asked questions

Is the Glow Worm Energy 15kW a system boiler, a combi boiler or a regular boiler?

If you’re looking for a system boiler for your house or flat, you may wish to the consider the Glow Worm Energy 15kW.

As with a heat only boiler, a system boiler requires the installation of a hot water cylinder but they do not need a cold water tank to work. This makes them suitable choices for homeowners planning a loft conversion or for properties without a loft or very limited attic space.

The primary heating and hot water system components are built in to system boilers and you can use the control panel to set the times that you wish your heating and hot water to be available. Hot water is stored in the cylinder for use throughout the day, but if you don't set your timer, heat and hot water will not be available instantly.

A system boiler can supply multiple taps and showers simultaneously and is suitable for both large families and properties with more than one bathroom - combi boilers struggle to do this.

Is the Glow Worm Energy 15kW system boiler suitable for my house or apartment?

Whether this Glow worm Energy 15kW System boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions - it means how powerful it is.

A boiler’s output is a measurement of the amount of power it can use to provide hot water to your taps and radiators. The higher its output rate, the more water it can heat.

If your new boiler’s output is too low, your hot water might not be as hot as you want it to be. If it's too high, you’ll be paying more for gas than you need to.

The output of the Glow Worm Energy 15kW system boiler is 15 kW, so which types of property would this be appropriate for?

A PlumbProud Gas Safe engineer would recommend that the most suitable type of property for a Glow Worm Energy 15kW system would be smaller homes and apartments containing up to 10 radiators and providing hot water for one bathroom.


How big is the Glow Worm Energy 15kW?

Glow Worm’s Energy 15kW is 700 mm tall, 390 mm wide, and 280 mm deep.

Is the Glow Worm Energy 15kW non-condensing or condensing?

Condensing gas boilers like the Glow Worm Energy 15kW are environmentally friendlier and cheaper to run so, if possible, we strongly recommend that you choose this or one of the very latest models.

Condensing boilers are much more efficient and economical to run because they contain a secondary heat exchanger that captures and recycles the warmth still present in the flue exhaust gases and the water vapour condensation for re-use, meaning that they use less gas to run.

How does the Glow Worm Energy 15kW system rate environmentally?

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about climate change.

Central heating produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

Would installing the Glow Worm Energy 15kW system in your home be an environmentally friendly decision? Let's look closely at the 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 Energy 15kW are 89.3% with a SEDBUK rating of "B".

The Energy Related Products (ERP) directive is Europe-wide legislation designed to reduce harmful gas emissions at all points of a product's life cycle - from the production process to its actual end use right through to final disposal.

The Glow Worm Energy 15kW has a rating of "A".

Does a Glow Worm Energy 15kW system boiler come with a warranty period?

The parts and labour warranty on the Glow Worm Energy 15kW lasts for 2 years.

Glow worm Energy 15kW System Gas boiler frequently asked questions

What kind of boiler is the Glow Worm Energy 15kW - standard, combi or system?

The Glow Worm Energy 15kW is an option you may wish to consider if you’re looking for a system boiler for your house or flat.

This type of boiler is better for larger homes and larger families where the demand for water is likely to be higher.

System boilers use a cylinder that draws water from the mains, heats it and then keeps it warm. The cylinder stores a large amount of water, meaning that you should have hot water all day. To be certain of this, make sure that you program your boiler to draw and heat water to meet times when demand is greater, like first thing in the morning before you and your family members go to work or school, and for the evening when everyone gets home.

Unlike heat only boilers, you won't need to find room in your attic for a cold water storage tank - suitable if you don't have an attic, your attic space is very limited, or you are planning an attic conversion in the near future.

Is the Glow Worm Energy 15kW system boiler a suitable option for my house or flat?

Whether this Glow worm Energy 15kW System boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions - it means how powerful it is.

The output level of a boiler tells you how much power it has to heat the water coming from your taps and warming up your radiators. The higher the output level, the greater the volume of water it can heat up.

If the output (measured in kilowatts) is too high, you'll pay higher gas bills and your water will be piping hot. Too low and the water coming out of your taps and being fed into your radiators will often be lukewarm.

The Glow Worm Energy 15kW system outputs at a maximum of 15 kW, so which types of property would this Glow worm Energy 15kW System boiler be appropriate for?

A boiler engineer would recommend that, at this level of output, the most suitable type of property for this Glow worm Energy 15kW System boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.


How big is the Glow Worm Energy 15kW?

The Glow Worm Energy 15kW is 700 mm tall, 390 mm wide, and 280 mm deep.

Is the Glow Worm Energy 15kW a condensing or non-condensing boiler?

We strongly recommend that you choose a condensing boiler like the Glow Worm Energy 15kW - the technology is improving every year so the newer the boiler, the better.

A condensing boiler captures and recycles the warmth still present in flue exhaust gases and water vapour condensation into heat, allowing it to perform more efficiently on tasks like heating the colder water returning from your radiators.

They also offer significant annual savings on household gas bills as well as being more environmentally friendly.

Is the Glow Worm Energy 15kW system environmentally friendly?

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 produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

Would the environmental impact of installing a Glow Worm Energy 15kW system in your home be positive? Let's look at the numbers.

In the UK, by law, all boilers manufactured since April 2018 must have a SEDBUK “A” rating and operate to a minimum level of 92% energy efficiency. Prior to this, the minimum was 88% – 88/89% would score a "B" and 90% or more an "A" on the SEDBUK scale.

The energy efficiency rating measures the amount of energy a boiler consumes when it's in use and how much it loses on non-core operations.

Following testing, the Glow Worm Energy 15kW was given an efficiency rating of 89.3% and a SEDBUK grading of "B".

The Energy Related Products (ERP) directive is Europe-wide legislation designed to reduce harmful gas emissions at all points of a product's life cycle - from the production process to its actual end use right through to final disposal.

The Glow Worm Energy 15kW has a rating of "A".

How long am I covered by the warranty for if the Glow Worm Energy 15kW breaks down?

Glow Worm offers a parts and labour warranty of 2 years on the Glow Worm Energy 15kW.
