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

The Glow Worm Energy 30kW boiler is an option you may wish to consider if you're looking for a system boiler for your house or flat.

System boilers are suitable for homes with a higher-than-average demand for central heating and water - for example, larger homes and larger families.

Combi boilers heat water on demand but the amount of water they can actually deliver to taps is determined by the mains water pressure, flow rate and power. System boilers instead use a hot water cylinder that stores and keeps water hot throughout the day. As long as you remember to program the times you want hot water and the cylinder still has water left in it, you should have hot water whenever you need it.

System boilers do not require a cold water storage tank either, unlike heat only boilers, meaning they're cheaper, quicker and easier to install.

Is a Glow Worm Energy 30kW system boiler appropriate for my house or apartment?

Whether this Glow worm Energy 30kW System boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions, however - it means how powerful it is.

Measured in kilowatts, a boiler's output level is an indication of the amount of power it has available to it to heat the water coming from your taps and for warming your radiators. The greater the output level, the more water it can heat.

If you choose a boiler whose output level is too low, you'll often find that the water is not as hot as you want it to be. If you choose a boiler whose level is too high, you'll be paying higher gas bills than you need to for years to come.

The output of the Glow Worm Energy 30kW system is 30 kW, so which types of property is this Glow worm Energy 30kW System boiler appropriate for?

A Gas Safe engineer would recommend that the Glow Worm Energy 30kW system boiler would be an ideal installation option for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

How large is a Glow Worm Energy 30kW boiler?

The Glow Worm Energy 30kW is 700 mm in height, 390 mm in width and 280 mm in depth.

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

Condensing boilers convert the warmth present in flue exhaust gases and water vapour condensation into heat which they then recycle to increase the temperature of the colder water returning to your system.

We recommend that homeowners choose a condensing boiler like the Glow Worm Energy 30kW for this reason - the more recent your model the better because the technology improves every year.

You'll benefit from lower quarterly gas bills and condensing boilers are also much more environmentally friendly.

Is the Glow Worm Energy 30kW system boiler environmentally friendly?

How we heat our homes and the effect that has on climate change has become important to many homeowners worried about the environment.

In the UK, central heating is responsible for 14% of greenhouse gas production. Domestic gas boilers emit large quantities of nitrogen dioxide in British cities.

Would choosing a Glow Worm Energy 30kW system help the environment? Let’s see what the performance figures suggest.

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 Energy 30kW was awarded an efficiency rating of 89.3%, equivalent to a SEDBUK grade of "B".

The Energy Related Products (ERP) Directive is a European directive which applies to all products that consume energy over their lifetime.

It encourages companies to create products that are environmentally friendlier at all life cycle stages, including initial manufacturing and end use right through to final disposal, with the aim of reducing harmful gas emissions.

The Glow Worm Energy 30kW is rated "A".

What is the warranty period on a Glow Worm Energy 30kW system boiler?

The Glow Worm Energy 30kW boiler comes with a 2 year warranty for parts and labour.
