Glow Worm Easicom 24 - combi, system or regular boiler?

Suitable for a house or a flat, the Glow Worm Easicom 24 combi boiler is worth considering if you want a combi boiler.

Traditional boilers often have up to two tanks that either store heated water or water to be heated later. Boiler manufacturers introduced combi boilers in the 1970s to avoid the need for those big tanks. Combi boilers allow homeowners to benefit from the reliable central heating and hot water level they want but without having to give up so much space within their properties - remember that homes in the UK are among the smallest in the developed world.

Your taps and radiators get the hot water they need with a combi boiler. Combi boilers draw cold water direct from the mains which is then heated instantly on demand and distributed to your radiators and taps.

However, combi boilers cannot heat very large volumes of water, which is their main disadvantage. So, for example, when someone wants to take a shower while another person wants to use a hot water tap to do the dishes, water pressure and quantity to both points decreases.

Is the Glow Worm Easicom 24 combi boiler suitable for my house or apartment?

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 Easicom 24 combi is 24 kW, so which types of property would this Glow worm Easicom 24 Combi boiler be an appropriate choice for?

A heating engineer would recommend that the Glow Worm Easicom 24 combi boiler would be a suitable installation option for smaller homes and apartments with up to 10 radiators and one bathroom.

With combi boilers like the Glow Worm Easicom 24, you need to take the flow rate into account as well as the output rate.

Combi boilers draw water from the mains and then instantly heat that water and send it to wherever in your home it's needed. Flow rates, measured in litres per minute, are subject to the mains water pressure in your area. So, for example, if the local mains water pressure is 11 litres per minute and the flow rate of your boiler is 14 litres per minute, the boiler will not be able to process more than 11 litres per minute. The flow rate of this Glow worm Easicom 24 Combi boiler is 10 L/m.

If you live in a home with lots of radiators or bathrooms where many people want to use hot water at the same time, a combi boiler may not be able to cope. For reference, a power shower uses about 10 litres of water per minute. If two people want showers at the same time or one person wants a shower and the other hot water from a tap in the kitchen, your boiler may not have a large enough flow rate even if the local mains water pressure is high.

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 proportions of a Glow Worm Easicom 24 boiler?

The Glow Worm Easicom 24 measures TBC mm high and TBC mm wide by a depth of TBC mm.

Is the Glow Worm Easicom 24 a non-condensing or condensing boiler?

The Glow Worm Easicom 24 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 Easicom 24 combi rated as environmentally friendly?

How we heat our homes has become a pressing issue of concern for many homeowners worried about climate change and the environmental impact of their personal choices.

Gas boilers are responsible for dangerous atmospheric levels of nitrogen dioxide emissions in Britain's biggest cities and, overall, 14% of the UK’s greenhouse gases are produced by our domestic central heating systems.

Would installing a Glow Worm Easicom 24 combi boiler in your home be a green choice? Let's look at the numbers.

All new British boilers must perform to a legal minimum energy efficiency of 92% (a low to good SEDBUK "A" rating). Prior to April 2018, the target was 88% (86-90% = SEDBUK "B" and 90%+ = SEDBUK "A").

Efficiency ratings are intended to let consumers know how much energy a boiler uses in its day-to-day activities and how much energy goes to waste.

The Glow Worm Easicom 24 was awarded an efficiency rating of 94%, equivalent to a SEDBUK grade of "A".

How many years does the warranty period cover on a Glow Worm Easicom 24 boiler?

A parts and labour warranty of 3 years is included with the Glow Worm Glow Worm Easicom 24 boiler.
