Glow worm Ultimate3 30 Combi Gas boiler frequently asked questions

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

The Glow Worm Ultimate3 30 may be worth considering if you are looking for a combi boiler for your house or flat.

In the past, most boilers needed one or more storage tanks to operate - one to store warm water and the other for storing water to be heated later. But storage tanks are problematic in properties where space is at a premium and particularly where there is no loft. Many properties in the UK are small and so manufacturers introduced combi boilers in the 1970s to eliminate the need for tanks.

With a combi boiler, the hot water for your radiators and taps is delivered on demand. The boiler instantly heats water it draws directly from the mains internally. It then distributes the heated water around your home at mains pressure as you need it.

It is important to bear in mind that, while combi boilers have many benefits, they can only heat a certain volume of water at any given time. This means that, if you run a shower at the same time as someone else is doing the washing up in the kitchen, the volume of water passing to each point will drop, causing a fall in pressure.

Is the Glow Worm Ultimate3 30 combi boiler a suitable option for my house or flat?

It's best to choose a boiler whose size or "output" is right for your property. With a boiler, however, size does not mean how big the boiler is, it means how much power it has.

The amount of hot water you get from showers, bathrooms, and sinks and heat from your radiators depends on your boiler's output (measured in kilowatts). The higher the level of output, the better your home will be heated and you can be more certain that the water from your taps will be as hot as you want.

However, you must be careful. You might not get the hot water you want if your boiler output is too low. If it's too high, you'll be paying more than you need to for gas.

With the Glow Worm Ultimate3 30 combi's output at 30 kW, which types of property would this Glow worm Ultimate3 30 Combi boiler be most appropriate for?

A PlumbProud heating engineer would likely recommend that this Glow worm Ultimate3 30 Combi boiler is suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

You also need to choose a combi boiler with the right flow rate for where you live.

A combi boiler's flow rate is the maximum volume of water (measured in litres per minute) that it can heat and distribute to your radiators, taps and showers at the same time. This Glow worm Ultimate3 30 Combi boiler's flow rate is 12 L/m.

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

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.

Combi boilers also struggle when multiple people in your home want to use hot water at the same time - for example, someone running the hot water tap in the kitchen and two people wanting to shower in separate bathrooms.

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.


Glow Worm Ultimate3 30 size

The Glow Worm Ultimate3 30 is TBC mm high by TBC mm wide by TBC mm deep.

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

We recommend that you select a condensing boiler like the Glow Worm Ultimate3 gas Glow Worm Ultimate3 30 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 30 combi an environmentally friendly boiler?

How we heat our homes has become a major issue for many people worried about climate change and environmental issues in general.

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.

Do the available figures suggest that installing the Glow Worm Ultimate3 30 combi 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 30 was given an efficiency rating of 89.6% 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.

Will I be covered if the Glow Worm Ultimate3 30 combi breaks down?

The Glow Worm Ultimate3 30 boiler comes with a parts and labour warranty lasting 10 years.

Glow worm Ultimate3 30 Combi Gas boiler frequently asked questions

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

If you are considering installing a combi boiler in your house or flat, then the Glow Worm Ultimate3 30 boiler is certainly worth investigating.

Combination or combi boilers are highly efficient and save a lot of space in your home. Combi boilers heat water directly from the mains when you turn on a tap and, as a result, you don’t need a hot water storage cylinder or a cold water tank in the roof space.

These boilers are, therefore, suitable for smaller homes and especially those without a loft. They are also cost-effective as the water is heated instantly and distributed on demand rather than being stored. Combi boilers are the most popular type of boilers in the UK and replacing an older boiler with a new combi boiler will reduce your gas bills significantly.

However, there are downsides to this type of boiler. If you take a shower while someone else is using a tap, less water will reach each point of usage at lower rates of pressure and temperatures as combi boilers can only heat a certain volume of water at any given time.

Would the Glow Worm Ultimate3 30 combi be a suitable boiler for my house or flat?

To determine that, we need to consider the size of the boiler. However, size doesn't refer to how big a boiler is - it means the size of its "output".

Your boiler’s output is a measurement of the power it has available to heat the volume of water required for your taps and radiators. The higher the output rate, the more water it can heat.

You need to be careful to select a boiler with the optimal level of output for your property though. That's because, if your boiler output is too low, your water and radiators will often not be as hot as you want them to be. If the output is too high, you’ll be paying more for gas than you need to.

The output of the Glow Worm Ultimate3 30 combi is 30 kW, so which types of property would this Glow worm Ultimate3 30 Combi boiler be appropriate for?

An experienced PlumbProud Gas Safe boiler installer would recommend that this Glow worm Ultimate3 30 Combi boiler is suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

When choosing a combi boiler like the Glow Worm Ultimate3 30, you need to consider the "flow rate" as well as the output rate. Flow rates (measured in litres per minute) indicate the volume of hot water that the boiler can heat up and then distribute to your taps and radiators.

However, combi boilers draw water from the mains and this means they can only heat the amount of water that actually enters your property.

What this means is that, if your mains pressure is 12 litres per minute, that is your boiler's effective flow rate even if it has the capacity to process 18 litres per minute. This Glow worm Ultimate3 30 Combi boiler's flow rate is 12 L/m.

To give you an idea of the flow rate you might need, a power shower typically requires around 12 litres of water per minute and a basin tap requires 4-8 litres 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.


Making space for the Glow Worm Ultimate3 30

The Glow Worm Ultimate3 30 is TBC mm tall, TBC mm wide, and TBC mm deep in size.

Ultimate3 30 – condensing or non-condensing?

This Glow Worm Ultimate3 30 is a condensing gas boiler - we always recommend that clients choose the latest condensing models to benefit from the technology, which continues to improve year after year.

Condensing boilers capture the heat still present in flue exhaust gases and water vapour condensation, processing them through a secondary heat exchanger to, among other tasks, heat colder water returning from your radiators.

By selecting a modern condensing boiler, you'll save money on your gas bills as well as benefitting the wider environment.

Is the Glow Worm Ultimate3 30 combi good for the environment?

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

As much as 14% of the UK’s greenhouse gas production derives from our domestic central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in Britain's largest cities.

Will choosing to install a Glow Worm Ultimate3 30 combi in your home help the environment? Let's review the 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 parts and labour warranty offered with this Glow worm Ultimate3 30 Combi boiler covers you for 10 years.
