Main Eco Compact 18kW System Gas boiler frequently asked questions

Is the Main Eco Compact 18kW boiler a standard, combi or system model?

Looking for a gas system boiler for your flat or house? Then the Main Eco Compact 18kW may be an option you should consider.

System boilers, like regular boilers, require a hot water cylinder (usually placed in a landing or airing cupboard) to work but they don’t require a separate cold water tank. This makes installation quicker and easier and, for homeowners with little loft space or who are considering a loft conversion, they're a more suitable choice.

System boilers don't need separate water tanks because they contain built-in circulating pumps that perform the same task. Just like heat only boilers, they require you to program in the times when you want heating and hot water to be available - they don't offer instant hot water like combi boilers. The cylinders keep whatever water they contain warm, although, if there is no hot water in the tank, you will have to wait up to an hour before hot water will come through your taps.

Is the Main Eco Compact 18kW system suitable for my house or flat?

You should make sure that the boiler you install in your property 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 has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your gas bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Main Eco Compact 18kW system's output at 18 kW, which types of property would this Main Eco Compact 18kW System boiler be most appropriate for?

A PlumbProud boiler engineer would recommend that this Main Eco Compact 18kW System boiler is suitable for smaller homes and apartments with up to 10 radiators and one bathroom.


How large is a Main Eco Compact 18kW boiler?

The Main Eco Compact 18kW is 700 mm tall, 390 mm wide, and 285 mm deep in size.

Is the Main Eco Compact 18kW condensing or non-condensing?

Condensing gas boilers like the Main Eco Compact 18kW 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 Main Eco Compact 18kW system 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.

As much as 14% of the UK’s greenhouse gas production derives from our domestic central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in Britain's largest cities.

If you would like your next boiler to help in the fight against climate change, would the Main Eco Compact 18kW system be a suitable choice?

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 Main Eco Compact 18kW was awarded an efficiency rating of 93%, equivalent to a SEDBUK grade of "A".

The ERP (or Energy Related Products Directive) is European legislation affecting products that consume energy throughout their lifetime.

The aim is to encourage companies to create environmentally friendlier products that reduce harmful gas emissions during manufacturing and when in use by the end client, right through to their eventual disposal.

In the case of the Main Eco Compact 18kW, the ERP rating is "A".

How long is the warranty offered by the manufacturer for the Main Eco Compact 18kW boiler?

Main offers a parts and labour warranty of 5 years on the Main Eco Compact 18kW.

Main Eco Compact 18kW System Gas boiler frequently asked questions

Is the Main Eco Compact 18kW a standard, combi or system boiler?

You may wish to consider installing the Main Eco Compact 18kW if you are 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 Main Eco Compact 18kW system boiler right for my house or apartment?

It's best to choose a boiler whose size or "output" is right for your property. With a boiler, however, size does not mean how big the boiler is, it means how much power it has.

The amount of hot water you get from showers, bathrooms, and sinks and heat from your radiators depends on your boiler's output (measured in kilowatts). The higher the level of output, the better your home will be heated and you can be more certain that the water from your taps will be as hot as you want.

However, you must be careful. You might not get the hot water you want if your boiler output is too low. If it's too high, you'll be paying more than you need to for gas.

With the Main Eco Compact 18kW system's output at 18 kW, which types of property would this Main Eco Compact 18kW System boiler be most appropriate for?

An experienced boiler engineer would recommend that this Main Eco Compact 18kW System boiler would be a suitable installation choice for smaller homes and apartments with up to 10 radiators and one bathroom.


Main Eco Compact 18kW dimensions

The Main Eco Compact 18kW boiler is 700 mm high, 390 mm wide, and 285 mm deep.

Main Eco Compact 18kW – non-condensing or 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 Main Eco Compact 18kW 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.

How energy efficient is the Main Eco Compact 18kW system?

As the British public has become more conscious of climate change, many homeowners consider the environment when choosing how to heat their homes.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

Would installing the Main Eco Compact 18kW system in your home be an environmentally friendly decision? Let's look closely at the figures.

Boilers manufactured in the UK must be tested and, by law, achieve an energy efficiency rating of 92% or above, equivalent to a SEDBUK "A" grade. Most boilers achieve an "A" rating meaning they are at least 88% efficient.

The energy efficiency of a boiler indicates the amount of energy it uses (and wastes) during operation.

The Main Eco Compact 18kW has been assigned an efficiency rating of 93% with a SEDBUK rating of "A".

In 2015, new legislation was introduced by the EU to encourage manufacturers to develop more energy-efficient products that emit fewer harmful gases throughout their lifetime.

The Energy Related Products Directive (ERP) applies to all products that consume energy, including during the manufacturing process, at the point of final disposal, and all points in between.

The ERP rating of the Main Eco Compact 18kW is "A".

If the Main Eco Compact 18kW breaks down, will I be covered by the warranty?

A parts and labour warranty of 5 years is included when you purchase the Main Eco Compact 18kW boiler through PlumbProud.
