Glow worm Betacom4 30 Combi Gas boiler frequently asked questions

What type of boiler is the Glow Worm Betacom4 30?

You might want to consider the Glow Worm Betacom4 30 for your house or flat if you are looking for a combi boiler.

Traditional boilers need one or more large tanks to work - one to heat and keep water warm for immediate use and the other to store water intended for heating later. Finding space for these large tanks is difficult in British residential property - remember that our houses and flats are among the smallest in the world. This is the problem that combi boilers were designed to solve when they were introduced in the 1970s.

Combi boilers don't need a tank - instead, they instantly heat water drawn from the mains using technology inside the boiler. This hot water is then distributed immediately to your taps or radiators on demand.

The biggest disadvantage to combi boilers is that they have a maximum capacity for heating water, meaning that they work best when only one point within a household wants hot water. For example, if someone is taking a shower and another person uses a hot water tap at the same time, the water pressure, volume and temperature to both points drops.

Should I install a Glow Worm Betacom4 30 combi boiler in my home?

Whether this Glow worm Betacom4 30 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 Betacom4 30 combi is 30 kW, so which types of property would this model be appropriate for?

Most Gas Safe boiler installers would likely recommend that, at this level of output, this Glow worm Betacom4 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 Betacom4 30 in your home, you should consider flow rates as well as output rates. This Glow worm Betacom4 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.


The size of the Glow Worm Betacom4 30

The Glow Worm Betacom4 30 has the following dimensions - TBC mm high, TBC mm wide, and TBC mm deep.

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

Condensing gas boilers like the Glow Worm Betacom4 30 are environmentally friendlier and cheaper to run so, if possible, we strongly recommend that you choose this or one of the very latest models.

Condensing boilers are much more efficient and economical to run because they contain a secondary heat exchanger that captures and recycles the warmth still present in the flue exhaust gases and the water vapour condensation for re-use, meaning that they use less gas to run.

Is the Glow Worm Betacom4 30 combi rated as environmentally friendly?

The effects of climate change on the environment are leading many homeowners to question the damage they might be doing by the way they heat their homes.

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.

Will installing a Glow Worm Betacom4 30 combi be a positive contribution to the environment? Let's see what the experts say.

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 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.

If the Glow Worm Betacom4 30 breaks down, will I be covered by the warranty?

A parts and labour warranty of 5 years is included with the Glow Worm Glow Worm Betacom4 30 boiler.

Glow worm Betacom4 30 Combi Gas boiler frequently asked questions

Which category of boiler does the Glow Worm Betacom4 30 fit into?

If you’re looking for a combi boiler for your house or flat, then the Glow Worm Betacom4 30 is one you may wish to consider.

Traditionally, boilers needed one or more large tanks installed in your property to store their heated water or water that was to be heated later. These tanks were often too large to be practical for most homes so the combi boiler was introduced to Britain in the 1970s by manufacturers to help homeowners overcome this issue.

Instead of using tanks as storage, a combi boiler heats water on demand. It draws water from the mains and heats it instantly on demand before distributing it to wherever it is needed in a property, be it your taps or radiators.

Unfortunately, combi boilers have one main disadvantage for larger properties or larger households. Because they have a maximum volume of water that can be heated on demand at any given time, water pressure, volume and temperature will drop if, for example, someone is taking a shower and another person in your home wants to use a hot water tap at the same time.

Is a Glow Worm Betacom4 30 combi boiler suitable for my house or apartment?

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 Betacom4 30 combi is 30 kW, so which types of property would this Glow worm Betacom4 30 Combi boiler be appropriate for?

An experienced Gas Safe boiler installer would recommend that, at this level of output, the most suitable type of property for this Glow worm Betacom4 30 Combi boiler would be medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

If you are considering installing a combi boiler in your home, you need to consider the flow rate as well as the output rate.

The flow rate is the volume of water (measured in litres per minute) that your boiler can instantly heat up and send around the home. The more demand in your home for water at the same time (for example, two people taking showers in different bathrooms), the higher the flow rate you'll need.

However, the actual flow rate your boiler can deliver is also determined by your mains water pressure. If you choose a boiler with a flow rate of 16l/m but the mains water pressure is 12l/m, your boiler will only perform to 12l/m. 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.


How large is a Glow Worm Betacom4 30 boiler?

The Glow Worm Betacom4 30 boiler is TBC mm high, TBC mm wide, and TBC mm deep.

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

We recommend that, if possible, you choose a condensing boiler like the Glow Worm Betacom4 30.

Condensing boilers are more energy-efficient. They achieve this efficiency by capturing the heat present in flue exhaust gases and water vapour condensation and recycling that heat to, for example, warm colder water coming back from your radiators.

By choosing the latest condensing boiler, you'll also notice a significant reduction in your gas bills, particularly if you're replacing a boiler more than 15 years old.

Is the Glow Worm Betacom4 30 combi considered environmentally friendly?

With environmental issues in the spotlight, more and more homeowners are becoming concerned about how they heat their homes and how much they're contributing towards combatting 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.

Will you be helping the environment if you decide to install a Glow Worm Betacom4 30 combi in your home? Let’s look at 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 Betacom4 30 has an efficiency rating of 89.2% with a SEDBUK grade of "B".

The Energy Related Products Directive (ERP) is European legislation that applies to all products which use or consume energy during their lifespan, including during the manufacturing process and when they're in actual use, right through to the point of final disposal.

The aim is to encourage manufacturers to create new products that are kinder to the environment and create fewer harmful gas emissions.

The Glow Worm Betacom4 30 has an ERP Heat rating of "A" and an ERP Water rating of "A".

What warranty does the Glow Worm Betacom4 30 combi boiler come with?

The Glow Worm Betacom4 30 is supplied with a parts and labour warranty of 5 years.
