Glow worm Energy 30kW Combi Gas boiler frequently asked questions

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

The Glow Worm Energy 30kW boiler could be suitable for your house or flat if you are looking for a new combi boiler.

The UK has some of the smallest homes in the Western world, which is partly why combi boilers were introduced in the 1970s. Traditional boilers require one or more large storage tanks which they use to either heat water and keep it warm or store water intended for heating later. These tanks took up a lot of space in people's homes.

Combi boilers save space because they don't require these tanks to operate. Instead, combis draw water direct from your mains supply then instantly heat and distribute it on demand.

The biggest disadvantage in using combi boilers is that they have a maximum capacity volume for heating water. While this may not be an issue in a small household, it could be for a larger household where there is higher demand for hot water. When more than one person is using the water, it is distributed between the two points, reducing the pressure and temperature at each point.

Is the Glow Worm Energy 30kW combi boiler suitable for my house or apartment?

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

Your boiler’s output is a measurement of the power it has available to it to heat the water you need for your radiators or for when you turn on a tap, bath or shower. A higher output rate means it has more power and can heat more water.

It's important to choose an output that matches the demand for water in your home because if your boiler has too low an output, you'll often find only lukewarm water comes out of your taps or heats your radiators. If it’s too high, you’ll be paying more for your gas than you need to.

The Glow Worm Energy 30kW combi has an output of 30 kW, so which types of property would this Glow worm Energy 30kW Combi boiler be appropriate for?

Most experienced boiler engineers would recommend that this Glow worm Energy 30kW Combi boiler would be suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

With combi boilers, flow rates are as important a consideration as output rates.

All combi boilers draw water from the mains. They then heat this water instantly whenever it's needed and distribute it to your radiators and taps.

A boiler's "flow rate" describes how much water a boiler can draw from the mains at any one time, which it then heats and sends around your home (measured in litres per minute). This Glow worm Energy 30kW Combi boiler's flow rate is 13 L/m.

If your home has a large number of radiators, a lot of bathrooms, or multiple people who wish to use the hot water at the same time, your combi boiler may not be able to draw as much water from the mains as it needs to serve everyone, regardless of how high the flow rate is.

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 Energy 30kW

The Glow Worm Energy 30kW measures 700 mm in height and has a width of 390 mm and a depth of 280 mm.

Energy 30kW – condensing or non-condensing?

The Glow Worm Energy 30kW boiler is a condensing gas boiler and we recommend that you select one of the latest models if possible.

Condensing boilers reduce homeowners' gas bills and are better for the environment. They do this by capturing and recycling the heat still present in the flue exhaust gases and water vapour condensation produced when boilers burn gas to generate the power they need to operate.

Is the Glow Worm Energy 30kW combi environmentally friendly?

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.

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

If you would like your next boiler to help in the fight against climate change, would the Glow Worm Energy 30kW combi be a suitable choice?

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 Energy 30kW was given an efficiency rating of 89.2% and a SEDBUK grading of "B".

The Energy Related Products Directive grades products according to the energy they consume and the harmful gas emissions they create, from manufacturing right through to final disposal, including how they're used by customers between these two points.

The Glow Worm Energy 30kW is rated "A" for heat and "A" for water.

How long is the warranty period on a Glow Worm Energy 30kW combi boiler?

The parts and labour warranty on the Glow Worm Energy 30kW covers all repair-related costs for 2 years while the heat exchange warranty covers you for [Heat Exchange Warranty] years.

Glow worm Energy 30kW Combi Gas boiler frequently asked questions

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

If you’re looking for a combi boiler for your house or flat, you may wish to the consider the Glow Worm Energy 30kW.

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.

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

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.

Boiler output is measured in kilowatts and tells you how much power a boiler can use to heat the water your taps, showers and radiators need. The higher the output, the more power it has.

When choosing a boiler, you should choose one that can cope with the peak demand for hot water in your home and not just your typical usage.

If its output is too low, sometimes your hot water will not be hot enough, but if your boiler's output is too high for your needs, your gas bills will go up and not down.

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

An experienced Gas Safe boiler installer would recommend that the Glow Worm Energy 30kW combi boiler would be an ideal installation option 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 Energy 30kW in your home, you should consider flow rates as well as output rates. This Glow worm Energy 30kW Combi boiler's flow rate is 13 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 Energy 30kW in millimetres

The Glow Worm Energy 30kW is 700 mm high by 390 mm wide by 280 mm deep.

Is the Glow Worm Energy 30kW condensing or non-condensing?

We always recommend to clients that they select the very latest condensing boiler for their home.

Condensing boilers like the Glow Worm Energy 30kW are more efficient with the gas they use in operation, meaning that you'll benefit from lower fuel bills. Condensing boilers are also better for the environment.

They achieve their efficiency by capturing and recycling the heat still present in the water vapour condensation and flue exhaust gases created when a boiler burns gas to get the energy it needs. It then reuses that recycled heat to perform a number of tasks, including heating the colder water that comes back to your boiler via the radiator.

Is the Glow Worm Energy 30kW combi environmentally friendly?

Many homeowners are now worried about climate change and the damage they do to the environment from heating their homes has become a subject of increasing concern.

Central heating produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

Would installing the Glow Worm Energy 30kW combi in your home be an environmentally friendly decision? Let's look closely at the figures.

An energy efficiency rating of 92% or above is a legal requirement for all boilers manufactured and installed in the UK today. 92% is equivalent to a low-to-middle "A" grade on the "Seasonal Efficiency of Domestic Boilers" (SEDBUK) scale.

Energy efficiency measures how much energy a boiler uses and wastes in the course of its normal operation. The lower the waste, the lower your gas bills.

The Glow Worm Energy 30kW was awarded an efficiency rating of "89.2%", equivalent to a "B" rating on the SEDBUK system.

The Energy Related Products Directive, also known as ERP, is European legislation that intends to reduce energy consumption related to products right from the initial manufacturing process through to eventual final disposal.

The purpose of the directive is to encourage manufacturers to create new products that are kinder to the environment and which result in lower overall harmful gas emissions through a product's entire life cycle.

The Glow Worm Energy 30kW has a rating of "A" for heat and "A" for water.

Is there a warranty on the Glow Worm Energy 30kW combi boiler if it breaks down?

On the Glow Worm Energy 30kW, the manufacturer offers a parts and labour warranty of 2 years.
