Main Eco Compact 25kW Combi Gas boiler frequently asked questions

Is the Main Eco Compact 25kW a regular, combi or system boiler?

When looking for a combi boiler for your house or flat, the Main Eco Compact 25kW might be a suitable option for you.

Combination or combi boilers are highly efficient and save a lot of space in your home. Combi boilers heat water directly from the mains when you turn on a tap and, as a result, you don’t need a hot water storage cylinder or a cold water tank in the roof space.

These boilers are, therefore, suitable for smaller homes and especially those without a loft. They are also cost-effective as the water is heated instantly and distributed on demand rather than being stored. Combi boilers are the most popular type of boilers in the UK and replacing an older boiler with a new combi boiler will reduce your gas bills significantly.

However, there are downsides to this type of boiler. If you take a shower while someone else is using a tap, less water will reach each point of usage at lower rates of pressure and temperatures as combi boilers can only heat a certain volume of water at any given time.

Would the Main Eco Compact 25kW combi be a suitable boiler for my house or flat?

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 Main Eco Compact 25kW combi is 25 kW, so which types of property would this Main Eco Compact 25kW Combi boiler be appropriate for?

Most experienced heating engineers would likely recommend that, at this level of output, this Main Eco Compact 25kW Combi boiler would be a suitable choice for smaller homes and apartments with up to 10 radiators and one bathroom.

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 Main Eco Compact 25kW Combi boiler's flow rate is 10 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 big is the Main Eco Compact 25kW?

The Main Eco Compact 25kW is 700 mm in height, 390 mm in width and 285 mm in depth.

Eco Compact 25kW – condensing or non-condensing?

The Main Eco Compact 25kW is a condensing gas boiler - where possible, we always recommend to clients that they choose one of the very latest condensing boilers to take advantage of this technology, which improves year after year.

Condensing boilers are more energy-efficient as they capture and recycle the heat contained in flue exhaust gases and water vapour condensation. They then use this heat to perform tasks like warming up colder water returning to the boiler from the radiators.

By choosing a condensing boiler, you'll help the environment as well as save money on your gas bills.

Is the Main Eco Compact 25kW combi a good choice for the environment?

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.

With central heating being responsible for 14% of greenhouse gas emissions in the UK, your choice of boiler matters. Gas boilers are also responsible for the significant atmospheric volumes of dangerous nitrogen dioxide emissions in larger British cities.

Would choosing a Main Eco Compact 25kW combi help in the fight against climate change? What do the performance statistics suggest?

All boilers manufactured and supplied in the UK must achieve an energy efficiency rating of at least 92% (an "A" SEDBUK grade). This is higher than the previous 88%, which was a legal requirement prior to April 2018.

The energy efficiency rating is used to work out how much energy a boiler both uses and wastes when it's switched on and working correctly - its standard functioning and operation.

The Main Eco Compact 25kW is rated as 93% energy efficient, equivalent to a "A" SEDBUK rating.

The Energy Related Products Directive (ERP) was introduced in 2015 and it applies to all products that consume energy throughout their lifetime, including during the manufacturing process and at the point of final disposal.

The purpose of the ERP is to ensure that companies create products that are kinder to the environment by reducing both the energy they use and the harmful emissions they produce.

The Main Eco Compact 25kW has an ERP rating of "A" for heat and "A" for hot water production.

What warranty do I get if I purchase the Main Eco Compact 25kW boiler?

Main offers a parts and labour warranty of 5 years on the Main Eco Compact 25kW.

Main Eco Compact 25kW Combi Gas boiler frequently asked questions

Main Eco Compact 25kW - a regular boiler, combi boiler or system boiler?

If you are considering installing a combi boiler in your house or flat, then the Main Eco Compact 25kW boiler is certainly worth investigating.

One of the reasons the combi boiler was introduced to Britain in the 1970s was because residential properties are among the smallest in the world. More traditional boilers require one or more large tanks to be stored around the home to function.

A combi boiler is a self-contained unit that draws water from the mains then heats and distributes it instantly and on demand - no tanks are needed.

They are the most popular type of boilers in the UK and offer only one major disadvantage - there is a maximum volume of water that can be heated at any one time. If that limit is exceeded by, for example, two people using a hot water tap at the same time, there will be a drop in water pressure, temperature and volume to both taps.

Would the Main Eco Compact 25kW combi be a suitable boiler for my house or flat?

Whether this Main Eco Compact 25kW Combi 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 Main Eco Compact 25kW combi is 25 kW, so which types of property is this Main Eco Compact 25kW Combi boiler appropriate for?

Most Gas Safe boiler installers would recommend that this Main Eco Compact 25kW Combi boiler would be suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

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 Main Eco Compact 25kW Combi boiler's flow rate is 10 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.


What size is the Main Eco Compact 25kW boiler?

The dimensions of the Main Eco Compact 25kW are 700 mm [H] x 390 mm [W] x 285 mm [D].

Is the Main Eco Compact 25kW condensing or non-condensing?

The Main Eco Compact 25kW is a condensing gas boiler - we strongly recommend that you choose one of the latest condensing models if possible.

With a condensing boiler, you save money on your gas bills because your boiler captures and recycles the heat present in the flue exhaust gases and water vapour condensation for re-use, meaning they operate far more economically and efficiently.

Is the Main Eco Compact 25kW 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.

Central heating accounts for 14% of greenhouse gas emissions in the UK. In larger British cities, gas boilers emit dangerous levels of nitrogen dioxide into the atmosphere.

Would installing a Main Eco Compact 25kW combi boiler in your home be a green choice? Let's look at the numbers.

All boilers manufactured in the UK from April 2018 must achieve a SEDBUK “A” grade and an energy efficiency rating of 92% or above. Before that, the minimum was 88% - efficiency ratings of 88% and 89% were scored a “B” and 90%+ an "A".

A boiler's energy efficiency rating describes how much energy it uses and wastes during its standard operation.

The energy efficiency of the Main Eco Compact 25kW was rated at 93% with a SEDBUK grading of "A".

The Energy Related Products (ERP) Directive is important European legislation that aims to limit energy use and harmful gas emissions during the manufacturing process, when the product is in use, and after it is disposed of.

For the Main Eco Compact 25kW, the ERP Heat rating is "A" and the ERP Water rating is "A".

Am I covered if my Main Eco Compact 25kW combi boiler breaks down?

The Main Eco Compact 25kW boiler comes with a parts and labour warranty lasting 5 years.
