Glow worm Ultimate3 30 Combi Gas boiler frequently asked questions

Is the Glow Worm Ultimate3 30 a combi, system or regular boiler?

If you are searching for a combi boiler for your house or flat, the Glow Worm Ultimate3 30 is certainly one to consider.

Boilers traditionally required the installation of one or more large tanks around your property. These were filled with water that was either being heated or was to be heated later. British homes are among the smallest in the world so, to solve the space problem, manufacturers introduced combi boilers in the 1970s to offer homeowners the warmth and hot water supply they needed while taking up much less space.

A combi boiler is designed to heat both radiators and taps on demand and at the same time. Water from the mains passes through a combi boiler and the boiler's technology instantly turns it into hot water. Your boiler then distributes the hot water throughout your home.

The main disadvantage of combi boilers is that they have a maximum water volume capacity. What this means is that, if one person is using the shower while another uses a hot tap simultaneously, less water gets to each area, resulting in a fall in water pressure at both points.

Is a Glow Worm Ultimate3 30 combi boiler suitable for my house or apartment?

You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".

Your boiler should be able to cope with peak hot water demand in your property and not just your average hot water usage. The output rate of a boiler is measured in kilowatts and tells you how much power a boiler can use to provide hot water to your taps, showers and radiators.

If the output of your boiler is too low, there will often be times when your water isn't as hot as you want. But if your boiler output is too high, it will be more costly to run (often unnecessarily).

The output of the Glow Worm Ultimate3 30 combi boiler is 30 kW kilowatts. Which types of property would this be appropriate for?

A PlumbProud Gas Safe boiler installer would recommend that the level of output from this Glow worm Ultimate3 30 Combi boiler would make it a suitable installation option for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

When choosing a combi boiler for your home, you need to think about "flow rates" as well as output rates. This Glow worm Ultimate3 30 Combi boiler's flow rate is 12 L/m.

This indicates the maximum volume of hot water (measured in litres per minute) that your boiler can heat then distribute to your taps, showers and radiators at any one time. The greater the demand for hot water in your home, the higher the flow rate you will require.

However, all combi boilers like the Glow Worm Ultimate3 30 draw water directly from the mains and heat it instantly.

This means that they can only heat and distribute water at the rate it enters the property (the "mains pressure" rate). For example, if your mains pressure is 11 litres per minute, this will be the highest flow rate you can achieve even if your boiler's flow rate is 17l/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 size is a Glow Worm Ultimate3 30 boiler?

Glow Worm’s Ultimate3 30 is TBC mm tall, TBC mm wide, and TBC mm deep.

Is the Glow Worm Ultimate3 30 non-condensing or condensing?

The Glow Worm Ultimate3 30 is a condensing gas boiler - we strongly suggest that you choose either this model or a recently released model if at all possible.

A condensing boiler captures and recycles the warmth present in flue exhaust gases and water vapour condensation created by the burning of gas to warm up the water coming back into your boiler - for example, from your radiators.

Condensing boilers cost less to run (lower gas bills) and are better for the environment.

Is the Glow Worm Ultimate3 30 combi boiler an environmentally friendly choice?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

Would choosing the Glow Worm Ultimate3 30 combi be an environmentally-friendly choice? If so, let's look at its performance figures.

All boilers manufactured after April 2018 in the UK must be rated as an “A” on the SEDBUK grading system, subject to a minimum energy efficiency rating of 92% or above. Before that, the minimum rate was 88% - boilers with an energy efficiency of 88% or 89% were given a “B” rating. Boilers scoring 90% or more were given an "A" rating.

The energy efficiency rating for a boiler describes the amount of energy it uses and how much goes to waste in operation.

The Glow Worm Ultimate3 30 has an efficiency rating of 89.6% with a SEDBUK grade of "B".

How many years does the warranty period cover on a Glow Worm Ultimate3 30 boiler?

The manufacturer offers a parts and labour warranty of 10 years on the Glow Worm Ultimate3 30 boiler to new customers.

Glow worm Ultimate3 30 Combi Gas boiler frequently asked questions

What type of boiler is the Glow Worm Ultimate3 30 - regular, system or combi?

You may wish to consider installing the Glow Worm Ultimate3 30 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 30 combi boiler a suitable choice for my property?

You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".

Your boiler should be able to cope with peak hot water demand in your property and not just your average hot water usage. The output rate of a boiler is measured in kilowatts and tells you how much power a boiler can use to provide hot water to your taps, showers and radiators.

If the output of your boiler is too low, there will often be times when your water isn't as hot as you want. But if your boiler output is too high, it will be more costly to run (often unnecessarily).

The output of the Glow Worm Ultimate3 30 combi boiler is 30 kW kilowatts. Which types of property would this be appropriate for?

Most Gas Safe boiler installers would likely recommend that, at this level of output, this Glow worm Ultimate3 30 Combi boiler would be a suitable choice for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

If you are thinking about installing a combi boiler like the Glow Worm Ultimate3 30 in your home, you should consider flow rates as well as output rates. This Glow worm Ultimate3 30 Combi boiler's flow rate is 12 L/m.

The flow rate indicates the maximum volume of water (measured in litres per minute) that your boiler can heat up and send to your radiators, taps and showers at any one time. The more taps and showers that could be in use simultaneously or the greater the number of radiators you have, the higher the flow rate you need.

However, you should establish what the mains pressure is at your property as a combi boiler can only heat the water that comes into your home.

For example, if your mains pressure is 12 litres per minute, your boiler can only heat and distribute hot water at a rate of 12 litres per minute even if it has a higher flow rate capacity. Typically, a power shower will require 10 litres of water per minute.

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 are the dimensions of the Glow Worm Ultimate3 30 boiler?

The Glow Worm Ultimate3 30's dimensions are TBC mm [H] x TBC mm [W] x TBC mm [D].

Is the Glow Worm Ultimate3 30 condensing or non-condensing?

Because of their increased energy efficiency, we recommend to all customers that they select one of the latest condensing boilers. Condensing boilers capture the heat from water vapour condensation and flue exhaust gases and recycle that heat to warm water entering the boiler (for example, from your radiators).

The Glow Worm Ultimate3 30 is a condensing gas boiler and choosing this model will result in a likely substantial reduction in your fuel bills, particularly if you're replacing an older, inefficient, non-condensing boiler.

How does the Glow Worm Ultimate3 30 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.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

Will choosing to install a Glow Worm Ultimate3 30 combi in your home help the environment? Let's review the figures.

The energy efficiency rating for a boiler describes the amount of energy it uses and wastes during operation and there are two different ways to measure it.

All boilers manufactured and supplied in the UK must have a SEDBUK rating of “A” subject to a minimum energy efficiency score of 92% or above. Before April 2018, the minimum energy efficiency score was 88% (88/89% = "B" SEDBUK rating, 90%+ = "A" SEDBUK rating).

The Glow Worm Ultimate3 30 scored an efficiency rating of 89.6% and a SEDBUK band rating of B.

How long am I covered by the warranty for if the Glow Worm Ultimate3 30 breaks down?

Glow Worm’s Ultimate3 30 boiler includes a parts and labour warranty of 10 years.
