Glow worm Ultimate3 25 System Gas boiler frequently asked questions

Glow Worm Ultimate3 25 - a regular, combi or system boiler?

You may wish to consider installing the Glow Worm Ultimate3 25 if you are looking for a system boiler for your house or flat.

System boilers are suitable for homes with a higher-than-average demand for central heating and water - for example, larger homes and larger families.

Tell the boiler when you want hot water using the control panel - it draws water from the mains, heats it and keeps it warm throughout the day in the hot water cylinder. As long as you remember to tell the boiler when you want hot water, you have a big enough cylinder, and there's not an unusually high demand for water on a particular day, you should have hot water whenever you need it.

System boilers do not require a cold water storage tank either, unlike heat only boilers, meaning they're cheaper, quicker and easier to install.

Is the Glow Worm Ultimate3 25 system boiler suitable for my house or apartment?

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 Ultimate3 25 system outputs at a maximum of 25 kW, so which types of property would this Glow worm Ultimate3 25 System boiler be appropriate for?

A boiler engineer would be likely to recommend that this Glow worm Ultimate3 25 System boiler is capable of providing heating and hot water to 10-15 radiators and two bathrooms and would therefore be most suitable for medium-sized homes and larger apartments.


The dimensions of the Glow Worm Ultimate3 25 are

The Glow Worm Ultimate3 25 is TBC mm high by TBC mm wide by TBC mm deep.

Is the Glow Worm Ultimate3 25 non-condensing or condensing?

We always recommend to clients that they select the very latest condensing boiler for their home.

Condensing boilers like the Glow Worm Ultimate3 25 are more efficient with the gas they use in operation, meaning that you'll benefit from lower fuel bills. Condensing boilers are also better for the environment.

They achieve their efficiency by capturing and recycling the heat still present in the water vapour condensation and flue exhaust gases created when a boiler burns gas to get the energy it needs. It then reuses that recycled heat to perform a number of tasks, including heating the colder water that comes back to your boiler via the radiator.

Is the Glow Worm Ultimate3 25 system an energy-efficient boiler?

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

Do the available figures suggest that installing the Glow Worm Ultimate3 25 system in your property would be an environmentally friendly choice?

By law, boilers manufactured and supplied in the UK must achieve a SEDBUK rating of "A" and work at a 92% minimum efficiency. Before April 2018, a minimum of 88% energy efficiency needed to be achieved (88/89% = SEDBUK "B" and 90% = SEDBUK "A").

Following official testing, the Glow Worm Ultimate3 25 was given an efficiency rating of 89.7% with a SEDBUK rating of "B".

Energy efficiency is a measure of how much energy is used and how much is wasted when a boiler is operating.

Am I covered if my Glow Worm Ultimate3 25 system boiler breaks down?

On the Glow Worm Ultimate3 25, the manufacturer offers a parts and labour warranty of 5 years.

Glow worm Ultimate3 25 System Gas boiler frequently asked questions

Glow Worm Ultimate3 25 - a regular boiler, combi boiler or system boiler?

If you want a system boiler for your flat or house, the Glow Worm Ultimate3 25 might be an option for you to consider.

System boilers require a hot water cylinder to work (normally stored in an airing or landing cupboard) but, unlike heat only boilers, they do not require a cold water tank. This makes them more suitable for homes that do not have lofts, where attic space is limited or where a loft conversion is being considered.

You program your heating and hot water to come on via the control panel. But if you forget to set the timer, you will have to wait a while for the water to heat up. Hot water is stored in the cylinder for use throughout the day and can be distributed to multiple showers and taps at the same time without a loss of pressure or temperature (something combi boilers really struggle with). For this reason, a system boiler is a suitable option for large families and homes with more than one bathroom.

As no cold-water tank is needed with a system boiler and many major system components are built into it, this type of boiler can be easier to install than a standard boiler.

Is the Glow Worm Ultimate3 25 system boiler the right choice for my house or apartment?

Whether this Glow worm Ultimate3 25 System boiler is right for your property depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output rating indicates how much energy a boiler can use in providing you with hot water and heat when you need it from your radiators and taps. The greater the output, the more water it can heat.

It's better to take advice on this from a registered installer because, if your boiler output is too low, your water and radiators might not get as hot as you would like them to be. However, if the output level is too high, you'll end up paying more on your gas bills than you need to.

Which types of property would this Glow worm Ultimate3 25 System boiler be appropriate for given its output of 25 kW?

A boiler engineer would be likely to recommend that this Glow worm Ultimate3 25 System boiler is capable of providing heating and hot water to 10-15 radiators and two bathrooms and would therefore be most suitable for medium-sized homes and larger apartments.


What dimensions does a Glow Worm Ultimate3 25 have?

The Glow Worm Ultimate3 25 is TBC mm tall, TBC mm wide, and TBC mm deep.

Glow Worm Ultimate3 25 – non-condensing or condensing?

We recommend that you select a condensing boiler like the Glow Worm Ultimate3 gas Glow Worm Ultimate3 25 for your home if possible because of the environmental benefits and the money you'll save on your gas bills.

Condensing boilers are much more energy-efficient than older, non-condensing models as they capture and recycle the heat still present in the water vapour condensation and flue exhaust gases that your boiler creates when burning gas for reuse.

How energy efficient is the Glow Worm Ultimate3 25 system?

As more of us are increasingly concerned about climate change, how we heat our homes and its impact on the environment has become an issue of importance to homeowners.

Central heating accounts for 14% of greenhouse gas emissions in the UK. In larger British cities, gas boilers emit dangerous levels of nitrogen dioxide into the atmosphere.

Will installing a Glow Worm Ultimate3 25 system be a positive contribution to the environment? Let's see what the experts say.

All boilers manufactured and installed in the UK are required by law to have an energy efficiency rating of at least 92%, equivalent to a good “A” rating on the SEDBUK scale. Before this, the minimum was 88% (ratings of 88% and 89% are equivalent to a high “B” SEDBUK rating and anything 90% or higher is an "A" rating).

A boiler's energy efficiency rating is designed to let you know how much energy is used and wasted during normal functioning.

The Glow Worm Ultimate3 25 was given an efficiency rating of 89.7% and a band rating of "B".

How long am I covered by the warranty for if the Glow Worm Ultimate3 25 breaks down?

A parts and labour warranty of 5 years is included when you purchase the Glow Worm Ultimate3 25 boiler through PlumbProud.
