Glow worm Ultimate3 25 System Gas boiler frequently asked questions

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

Suitable for a house or a flat, the Glow Worm Ultimate3 25 system boiler is worth considering if you want a system boiler.

System boilers share many similarities with more traditional heat only boilers, like the need to program the times you want them to provide you with heat and hot water - just use the control panel to do this.

Where they differ from regular boilers is that they do not require a separate cold-water tank - everything is done within the hot water cylinder, which contains built-in circulating pumps. This makes them easier to install as there is one less component to fit and makes them more suitable for properties with no loft space, smaller lofts or for homeowners who are considering converting their loft.

As long as you have programmed your system boiler in advance, you will have the hot water you need ready for whenever you want to use it. Once the water is heated, it will remain available, warm, inside the tank until it’s all used up. It will then draw more water from the mains to start heating so that it can provide heat and hot water for the times you've told the system boiler you need it.

Is a Glow Worm Ultimate3 25 system a suitable choice for my house or flat?

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 Ultimate3 25 system's output is 25 kW, so which types of property would this Glow worm Ultimate3 25 System boiler be appropriate for?

An experienced Gas Safe boiler installer would recommend that the Glow Worm Ultimate3 25 system boiler would be an ideal installation option for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


How large is a Glow Worm Ultimate3 25 boiler?

The dimensions of the Glow Worm Ultimate3 25 are TBC mm [H] x TBC mm [W] x TBC mm [D].

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

The Glow Worm Ultimate3 25 is a condensing gas boiler - this is the type of boiler we recommend to most clients because they're better for the environment and they will save money on annual fuel bills.

A condensing boiler captures and recycles the warmth still present in both the flue exhaust gases and water vapour condensation created when gas is burned to provide your boiler with power.

This means it needs less gas to operate and it uses this extra energy to perform a number of tasks, including heating the colder water that comes back to the boiler from the radiators in your home.

How energy efficient is the Glow Worm Ultimate3 25 system boiler?

How we heat our homes and the damage this does to the environment has become a pressing concern for many homeowners worried about the effects and impact of climate change.

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.

Is the Glow Worm Ultimate3 25 system boiler an environmentally friendly choice for your home? Here’s what the figures say.

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.

What is the length of the warranty on the Glow Worm Ultimate3 25?

The Glow Worm Ultimate3 25 boiler is covered by a parts and labour warranty of 5 years.

Glow worm Ultimate3 25 System Gas boiler frequently asked questions

What type of boiler is the Glow Worm Ultimate3 25?

Looking for a gas system boiler for your house or flat? If you are, the Glow Worm Ultimate3 25 boiler may be worth considering.

System boilers work similarly to heat only boilers in that they need a hot water cylinder (usually installed in the home’s airing or landing cupboard) to operate. Unlike heat only boilers though, system boilers don’t require a separate cold-water tank, making them a more suitable choice in homes with little or no attic space or where homeowners are planning a loft conversion in the future.

Instead of large cold-water tanks, system boilers use built-in circulating pumps to provide hot water to your taps and radiators. This makes them easier to install from scratch as they have one less component to find room for and fit.

System boilers need to be programmed with the time you want heat and hot water - they don't offer hot water on demand like combi boilers.

Is a Glow Worm Ultimate3 25 system boiler appropriate 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?

An experienced PlumbProud Gas Safe boiler installer would recommend that this Glow worm Ultimate3 25 System boiler is suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


What are the proportions of a Glow Worm Ultimate3 25 boiler?

The Glow Worm Ultimate3 25 is TBC mm [H] by TBC mm [W] by TBC mm [D] in size.

Is this Glow Worm boiler condensing or non-condensing?

The Glow Worm Ultimate3 25 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 Ultimate3 25 system environmentally friendly?

How we heat our homes and the effect that has on climate change has become important to many homeowners worried about the environment.

Central heating creates 14% of the UK’s greenhouse gases. And in Britain's larger cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Will choosing to install a Glow Worm Ultimate3 25 system in your home help the environment? Let's review the figures.

An energy efficiency rating of 92% or above is a legal requirement for all boilers manufactured and installed in the UK today. 92% is equivalent to a low-to-middle "A" grade on the "Seasonal Efficiency of Domestic Boilers" (SEDBUK) scale.

Energy efficiency measures how much energy a boiler uses and wastes in the course of its normal operation. The lower the waste, the lower your gas bills.

The Glow Worm Ultimate3 25 was awarded an efficiency rating of "89.7%", equivalent to a "B" rating on the SEDBUK system.

What warranty does the Glow Worm Ultimate3 25 system boiler come with?

A parts and labour warranty of 5 years is included with the Glow Worm Glow Worm Ultimate3 25 boiler.
