Glow worm Betacom4 30 Combi Gas boiler frequently asked questions

Glow Worm Betacom4 30 - a regular, combi or system boiler?

The Glow Worm Betacom4 30 is a combi boiler you may wish to consider if you want this type of boiler for your house or flat.

In older British homes, traditional boilers required you to find room for one or more storage tanks. One tank would keep hot water warm and the other stored cold water for later heating. Manufacturers introduced combi boilers to the UK in the 1970s so that homeowners could get the warmth and hot water they needed without having to sacrifice too much valuable space – remember that residential property in this country is among the smallest in the Western world.

Combi boilers deliver hot water to your radiators and taps using water they draw directly from the mains supply. As mains water travels through a combi boiler, the technology within it heats the cold water instantly and on demand. The hot water is then distributed throughout your house.

Combi boilers have one drawback, however: they can only heat a certain amount of water within a given time. For example, if someone uses the shower and another person uses the hot water tap at the same time, water pressure drops because water reaches each point differently.

Is the Glow Worm Betacom4 30 combi boiler a suitable option for my house or flat?

Selecting the right boiler for your property means selecting a boiler that is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - its "output".

The output rate tells you how much energy your boiler has to use to provide you and your family with hot water and central heating. A higher output rate means that it can heat greater volumes of water.

Please be aware, though - if you choose a boiler whose output is too low, the water in your radiators and coming from your taps may not be warm enough. Conversely, if you choose a boiler with too high an output, you'll pay more for gas than is necessary.

The Glow Worm Betacom4 30 combi boiler has an output level of 30 kW, so which types of property would it be appropriate for?

An experienced Gas Safe boiler installer would recommend that the Glow Worm Betacom4 30 combi boiler would be an ideal installation option for medium-sized homes and larger apartments with 10-15 radiators and two 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 Betacom4 30 Combi boiler is 12 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.

Betacom4 30 – non-condensing or condensing?

Condensing boilers like the Glow Worm Betacom4 30 improve energy efficiency and reduce your annual expenditure on gas.

They do this by capturing and recycling the warmth still present in water vapour condensation and flue exhaust gases to, for example, increase the temperature of the colder water returning from your radiators.

Condensing boilers are also much better for the environment because they emit fewer greenhouse gases.

How energy efficient is the Glow Worm Betacom4 30 combi boiler?

With more and more of us concerned about environmental issues and climate change, how we heat our homes has become an important issue to many homeowners.

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.

If you decide to install a Glow Worm Betacom4 30 combi in your home, will you be helping the environment with your choice? Let’s have a look at the figures.

All boilers manufactured and installed in the UK are required to have an energy efficiency rating of 92% or above (or a good “A” SEDBUK rating). Before April 2018, when the law changed, the minimum energy efficiency level permissible was 88% (86-90% is a SEDBUK "B" rating and 90%+ is an "A" rating).

A boiler's energy efficiency rating indicates the amount of energy used and wasted during normal operational performance.

Following its assessment, the Glow Worm Betacom4 30 was given an efficiency rating of 89.2% and a SEDBUK grading of "B".

The ERP (or Energy Related Products Directive) is a European regulation governing products which require energy to operate throughout their lives and encourages manufacturers to create products that are more environmentally friendly.

The legislation is designed to reduce the potential for harmful gas emissions during manufacturing and actual use right through to the point of final disposal.

For the Glow Worm Betacom4 30, the ERP rating is "A" for heat and "A" for hot water production.

Is this Glow Worm Betacom4 30 combi covered by a warranty?

The Glow Worm Betacom4 30 boiler comes with a parts and labour warranty lasting 5 years.

Glow worm Betacom4 30 Combi Gas boiler frequently asked questions

Is the Glow Worm Betacom4 30 a combi boiler, system boiler or regular boiler?

Looking for a gas combi boiler for your flat or house? Then the Glow Worm Betacom4 30 may be an option you should consider.

Combi boilers have much to recommend them - not least the fact that they save a lot of space. Combination (or combi) boilers were introduced by manufacturers in the 1970s to provide practical central heating and hot water distribution to smaller properties - remember that UK houses and flats tend to be among the smallest in the developed world.

Traditional boilers require one or more storage tanks to keep hot water warm and to store water for heating later. In contrast, combi boilers draw water directly from the mains supply and heat it instantly, removing the need for a storage tank. The heated water is then distributed to your taps and radiators on demand.

While combi boilers are suitable choices for many properties, especially those without a loft, there is also a disadvantage in using them. Water is heated instantly and the volume of water that can be heated at any one time is limited. This can result in less water being sent to taps and showers if more than one is being used simultaneously. In these instances, the water pressure to both points will drop.

Is the Glow Worm Betacom4 30 combi boiler from the Betacom4 range a suitable choice for my house or flat?

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".

Output measures in kilowatts how much power a boiler can use when heating water for your radiators or taps. The higher the output rate, the more water it can heat.

If the output rate is too low, your hot water might often be only lukewarm, and if it is too high, you will be paying more for your gas than you need to.

The Glow Worm Betacom4 30 combi boiler has an output of 30 kW, so which types of property would it be most appropriate for?

A boiler engineer would be likely to recommend that this Glow worm Betacom4 30 Combi 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.

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 Betacom4 30 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 Betacom4 30 Combi boiler's flow rate is 12 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.


The size of the Glow Worm Betacom4 30

The dimensions of the Glow Worm Betacom4 30 are TBC mm [H] x TBC mm [W] x TBC mm [D].

Is the Glow Worm Betacom4 30 a condensing or non-condensing boiler?

Condensing gas boilers like the Glow Worm Betacom4 30 are more energy-efficient and choosing one for your home will cut the amount you pay every year for your gas.

They do this by capturing the heat in water vapour condensation and in exhaust gases which would normally be expelled via the flue. They then recycle that heat, returning it to the system to, among other tasks, reheat colder water that is returning to your boiler from your radiators.

Is the Glow Worm Betacom4 30 combi an energy-efficient boiler?

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.

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.

If you decide to install a Glow Worm Betacom4 30 combi in your home, will you be helping the environment with your choice? Let’s have a look at the figures.

In the UK, by law, all boilers manufactured since April 2018 must have a SEDBUK “A” rating and operate to a minimum level of 92% energy efficiency. Prior to this, the minimum was 88% – 88/89% would score a "B" and 90% or more an "A" on the SEDBUK scale.

The energy efficiency rating measures the amount of energy a boiler consumes when it's in use and how much it loses on non-core operations.

Following testing, the Glow Worm Betacom4 30 was given an efficiency rating of 89.2% and a SEDBUK grading of "B".

The Energy Related Products Directive (ERP) was introduced in 2015 and it applies to all products that consume energy throughout their lifetime, including during the manufacturing process and at the point of final disposal.

The purpose of the ERP is to ensure that companies create products that are kinder to the environment by reducing both the energy they use and the harmful emissions they produce.

The Glow Worm Betacom4 30 has an ERP rating of "A" for heat and "A" for hot water production.

How many years does the warranty period cover on a Glow Worm Betacom4 30 boiler?

The Glow Worm Betacom4 30 boiler has a warranty covering parts and labour costs for up to 5 years after installation.
