Glow worm Ultimate3 35 Combi Gas boiler frequently asked questions

What type of boiler is Glow Worm’s Ultimate3 35 - system, regular or combi?

The Glow Worm Ultimate3 35 boiler could be suitable for your house or flat if you are looking for a new 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 a Glow Worm Ultimate3 35 combi a suitable choice for my house or flat?

Whether this Glow worm Ultimate3 35 Combi boiler is right for where you live 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 of a boiler is measured in kilowatts and indicates how much energy it can use to heat the water needed for your radiators, taps and showers. The greater the output, the more water it can heat.

A boiler whose output is too high will give you hot water and warm radiators but also higher gas bills, whereas a boiler whose output is too low will result in cheaper gas bills but the water might not always be as hot as you want it to be.

The output of the Glow Worm Ultimate3 35 combi is 35 kW, so which types of property would this model be appropriate for?

To most experienced Gas Safe boiler installers, the Glow Worm Ultimate3 35 combi Ultimate3 would be most suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

In addition to output rates, you need to consider a combi boiler's flow rate when making your choice.

The flow rate of your boiler dictates the maximum volume of water (measured in litres per minute) that it can heat and distribute to your taps, showers and radiators at any one time.

However, a combi boiler like the Glow Worm Ultimate3 35 can only heat and deliver water at the rate at which it actually enters your property. For this reason, you should also find out what the mains pressure to your house is before purchasing a boiler.

It's pointless spending more money on a boiler with a 17l/m flow rate if the local water pressure is 11l/m. To give you an indication of average water demand, a power shower typically requires 12 litres of water per minute and a basin tap 4-8 litres. This Glow worm Ultimate3 35 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.


How large is the Glow Worm Ultimate3 35?

The Glow Worm Ultimate3 35 measures TBC mm in height and has a width of TBC mm and a depth of TBC mm.

Glow Worm Ultimate3 35 – condensing or non-condensing?

We recommend that you select a condensing boiler like the Glow Worm Ultimate3 gas Glow Worm Ultimate3 35 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.

Is the Glow Worm Ultimate3 35 combi an energy-efficient boiler?

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on climate change.

Approximately 14% of the UK's greenhouse gas production is caused by our central heating systems. The gas boilers in larger urban areas of Britain are mainly responsible for emissions of toxic nitrogen dioxide.

Will you be helping the environment if you decide to install a Glow Worm Ultimate3 35 combi in your home? Let’s look at the figures.

Under current UK law, all boilers must achieve a minimum energy efficiency level of 92% (a low to good SEDBUK "A" rating). The minimum level was raised from its previous 88% in April 2018.

Energy efficiency scores are intended to inform consumers of the amount of energy used and wasted when a boiler is in normal operation.

The Glow Worm Ultimate3 35 was awarded an efficiency rating of 89.7% with a SEDBUK band rating of "B".

How long am I covered by the warranty for if the Glow Worm Ultimate3 35 breaks down?

You receive a parts and labour warranty of 10 years with the Glow Worm Ultimate3 35 boiler.

Glow worm Ultimate3 35 Combi Gas boiler frequently asked questions

Is the Glow Worm Ultimate3 35 a system, regular or combi boiler?

The Glow Worm Ultimate3 35 may be worth considering if you are looking for a combi boiler for your house or flat.

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 Ultimate3 35 combi boiler a suitable choice for my property?

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 35 combi's output is 35 kW, so which types of property would this Glow worm Ultimate3 35 Combi boiler be appropriate for?

A PlumbProud Gas Safe engineer would recommend that this Glow worm Ultimate3 35 Combi boiler is suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

With combi boilers, you need to consider the flow rate as well as the output rate. The flow rate (shown in litres per minute) measures how much water your boiler can draw from the mains which it then instantly heats and distributes to your taps and radiators.

However, a high flow rate is of little to no value if your local water pressure is low. If your local mains water pressure is 10l/m and your flow rate is 12l/m, your boiler will only be able to process 10l/m.

If you live in an area with high water pressure but your household has multiple bathrooms and/or radiators and many members of your household want to use hot water at the same time (like morning or evening baths or showers), it's unlikely that you'll be able to find a combi with a high enough flow rate.

As an indication, a power shower needs about 10 litres of water per minute, whereas the flow rate of this Glow worm Ultimate3 35 Combi boiler is 14 L/ml/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 dimensions does a Glow Worm Ultimate3 35 have?

The size of the Glow Worm Ultimate3 35 boiler is TBC mm high, TBC mm wide, and TBC mm deep.

Is the Glow Worm Ultimate3 35 a condensing or non-condensing boiler?

The Glow Worm Ultimate3 35 is a condensing gas boiler - where possible, we always recommend to clients that they choose one of the very latest condensing boilers to take advantage of this technology, which improves year after year.

Condensing boilers are more energy-efficient as they capture and recycle the heat contained in flue exhaust gases and water vapour condensation. They then use this heat to perform tasks like warming up colder water returning to the boiler from the radiators.

By choosing a condensing boiler, you'll help the environment as well as save money on your gas bills.

How does the Glow Worm Ultimate3 35 combi rate environmentally?

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on climate change.

About 14% of the greenhouse gases we produce in the UK come from the power needed for central heating. In bigger British cities, gas boilers are a significant source of nitrogen dioxide emissions.

Would choosing the Glow Worm Ultimate3 35 combi help the environment? Let's see what the statistics suggest.

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 35 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 warranty period on a Glow Worm Ultimate3 35 combi boiler?

You receive a parts and labour warranty of 10 years with the Glow Worm Ultimate3 35 boiler.
