Firebird Envirogreen Slimline Combi C26 Combi Oil boiler frequently asked questions

What kind of boiler is the Firebird Envirogreen Slimline Combi C26 - standard, combi or system?

If you are searching for a combi boiler for your house or flat, the Firebird Envirogreen Slimline Combi C26 is certainly one to consider.

Traditional boilers have one or more large tanks in which they store either heated water or water to be heated later. Manufacturers originally introduced combi boilers to the market in the 1970s to enable homeowners to save space - UK residential properties are among the smallest in the Western world.

Combi boilers don't need these tanks because they draw water directly from the mains and instantly heat it on demand thanks to the technology inside the boiler. Combi boilers then distribute this hot water to your home’s taps and radiators when needed.

The most significant disadvantage of combi boilers is that they are not ideal in larger homes where multiple people might want hot water at the same time – for example, if someone is having a shower while another wants to wash dishes in the kitchen. This is because combi boilers have a maximum volume of water that they can heat. When two people want hot water at the same time, the water temperature, pressure and volume delivered to both points drop.

Should I install a Firebird Envirogreen Slimline Combi C26 combi boiler in my home?

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

A boiler’s output indicates the amount of power it can use when heating the water which it then sends to your taps and radiators. The higher the output rate, the more water it can heat.

If a boiler’s output is too low, there will be times when your hot water might not be as hot as you want it to be. If it is too high, you’ll likely be paying more than you need to for your gas.

Measured in kilowatts, the Firebird Envirogreen Slimline Combi C26 combi's output level is 26 kW, so which types of property would this Firebird Envirogreen Slimline Combi C26 Combi boiler be an appropriate choice for?

Most Gas Safe engineers would suggest that the most suitable type of property for installing a Firebird Envirogreen Slimline Combi C26 combi boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.

In addition to output rates, you need to consider a combi boiler's flow rate when making your choice.

The flow rate of your boiler dictates the maximum volume of water (measured in litres per minute) that it can heat and distribute to your taps, showers and radiators at any one time.

However, a combi boiler like the Firebird Envirogreen Slimline Combi C26 can only heat and deliver water at the rate at which it actually enters your property. For this reason, you should also find out what the mains pressure to your house is before purchasing a boiler.

It's pointless spending more money on a boiler with a 17l/m flow rate if the local water pressure is 11l/m. To give you an indication of average water demand, a power shower typically requires 12 litres of water per minute and a basin tap 4-8 litres. This Firebird Envirogreen Slimline Combi C26 Combi boiler's flow rate is 16 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.


Firebird Envirogreen Slimline Combi C26 - size in millimetres

The dimensions of the Firebird Envirogreen Slimline Combi C26 are 855 mm [H] x 520 mm [W] x 600 mm [D].

Compact wall-hung boilers have been the most popular boiler installation choice over the past two decades. If you have a floor-standing boiler in your home like the Firebird Envirogreen Slimline Combi C26 and you want to replace it with a wall-mounted unit so that you and your family have more space to live, this is possible - however, please note that there may be an additional premium on fitting costs if your current pipework needs replacing.

The savings you make on your oil bills over the coming years will cover the cost of installation completely.

Please also bear in mind that if you’re considering replacing your current standard or system boiler with the Firebird Envirogreen Slimline Combi C26, you will need to have your hot water cylinder and/or expansion tank removed.

For information and guidance on the best course of action, please contact PlumbProud and we’ll share our advice with you.

Is the Firebird Envirogreen Slimline Combi C26 a condensing or non-condensing boiler?

The Firebird Envirogreen Slimline Combi C26 is a condensing oil boiler - this is the type of boiler we recommend to most clients because they're better for the environment and they will save money on annual fuel bills.

A condensing boiler captures and recycles the warmth still present in both the flue exhaust gases and water vapour condensation created when oil is burned to provide your boiler with power.

This means it needs less oil to operate and it uses this extra energy to perform a number of tasks, including heating the colder water that comes back to the boiler from the radiators in your home.

Is the Firebird Envirogreen Slimline Combi C26 combi rated as environmentally friendly?

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

Central heating creates 14% of the UK’s greenhouse gases. And in Britain's larger cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Will you be helping the environment if you decide to install a Firebird Envirogreen Slimline Combi C26 combi in your home? Let’s look at the figures.

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 Firebird Envirogreen Slimline Combi C26 is rated as 93% energy efficient, equivalent to a "A" SEDBUK rating.

The ERP, short for the Energy Related Products Directive, is a European directive aimed at encouraging manufacturers to create products that are environmentally friendlier at all stages, including during manufacturing, when the product is in active use, right through to the point of final disposal.

The Firebird Envirogreen Slimline Combi C26 has a rating of "A" for heat and "A" for hot water production.

Does a Firebird Envirogreen Slimline Combi C26 combi boiler come with a warranty period?

The Firebird Envirogreen Slimline Combi C26 boiler has a warranty covering parts and labour costs for up to 2 years after installation.

Firebird Envirogreen Slimline Combi C26 Combi Oil boiler frequently asked questions

Is the Firebird Envirogreen Slimline Combi C26 boiler a combi, system or regular boiler?

You might want to consider the Firebird Envirogreen Slimline Combi C26 for your house or flat if you are looking for a combi boiler.

Combi boilers provide hot water or heating for your home on demand. You just need to turn the tap to get hot water or switch on the radiator and you’ll feel your home warm up within minutes.

In contrast, traditional boilers required either one or two large storage tanks to work - one to heat and keep water warm and the other to hold cold water for later heating. If the immersion tank was empty, it wasn’t uncommon to wait up to an hour for enough hot water to fill a bath, for example.

Combi boilers draw cold water from the mains and then heat it instantly whenever it's needed, all from one small unit.

The one disadvantage to combi boilers is that, if more than one point is in use at any one time (for example, if someone is taking a shower and another person turns on a hot water tap elsewhere in the property), water pressure, temperature and volume drop to both points.

Is a Firebird Envirogreen Slimline Combi C26 combi boiler right for my house or apartment?

It's best to choose a boiler whose size or "output" is right for your home.

The more hot water and heat you want, the higher the output level of your boiler should be. Output is measured in kilowatts and it describes the maximum level of power your boiler has to heat water.

If your output level is too low, your boiler will not have the power it needs to get your water as hot as you want it, particularly when there's a lot of demand for it. Choose a boiler whose output level is too high and you'll have all the hot water you need but will be paying too much for it through higher oil bills.

Which types of property would this Firebird Envirogreen Slimline Combi C26 Combi boiler be appropriate for given its output of 26 kW?

A Gas Safe boiler installer would recommend that this Firebird Envirogreen Slimline Combi C26 Combi boiler would provide adequate heating and hot water for smaller homes and apartments with up to up to 10 radiators and one bathroom.

With combi boilers, you need to consider the flow rate as well as the output rate. The flow rate (shown in litres per minute) measures how much water your boiler can draw from the mains which it then instantly heats and distributes to your taps and radiators.

However, a high flow rate is of little to no value if your local water pressure is low. If your local mains water pressure is 10l/m and your flow rate is 12l/m, your boiler will only be able to process 10l/m.

If you live in an area with high water pressure but your household has multiple bathrooms and/or radiators and many members of your household want to use hot water at the same time (like morning or evening baths or showers), it's unlikely that you'll be able to find a combi with a high enough flow rate.

As an indication, a power shower needs about 10 litres of water per minute, whereas the flow rate of this Firebird Envirogreen Slimline Combi C26 Combi boiler is 16 L/ml/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.


What size is the Firebird Envirogreen Slimline Combi C26 boiler?

The size of the Firebird Envirogreen Slimline Combi C26 boiler is 855 mm high, 520 mm wide, and 600 mm deep.

There are hundreds of thousands of properties whose central heating systems are powered by floor-standing boilers like the Firebird Envirogreen Slimline Combi C26. If you're considering switching from your current floor-standing to a new wall-mounted model to free up space inside your home for you and your family, we can do this work for you. However, when you change the type of boiler in your home, please bear in mind that we often need to replace the piping at extra cost.

However, given the quarterly savings you'll make on your oil bills as a result of switching, you should be able to recoup your investment in full within a few years.

If you are considering the Firebird Envirogreen Slimline Combi C26 as a replacement for your existing heat only or system boiler, you'll also have to budget for the removal of your hot water cylinder and/or your expansion tank.

If you would like professional information and guidance on the best choices for your home, please contact PlumbProud for advice.

Is the Firebird Envirogreen Slimline Combi C26 non-condensing or condensing?

Condensing oil boilers like the Firebird Envirogreen Slimline Combi C26 are more energy-efficient and choosing one for your home will cut the amount you pay every year for your oil.

They do this by capturing the heat in water vapour condensation and in exhaust gases which would normally be expelled via the flue. They then recycle that heat, returning it to the system to, among other tasks, reheat colder water that is returning to your boiler from your radiators.

How energy efficient is the Firebird Envirogreen Slimline Combi C26 combi boiler?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of climate change.

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.

Would the environmental impact of installing a Firebird Envirogreen Slimline Combi C26 combi in your home be positive? Let's look at the numbers.

All boilers manufactured and installed in the UK are required by law to have an energy efficiency rating of at least 92%, equivalent to a good “A” rating on the SEDBUK scale. Before this, the minimum was 88% (ratings of 88% and 89% are equivalent to a high “B” SEDBUK rating and anything 90% or higher is an "A" rating).

A boiler's energy efficiency rating is designed to let you know how much energy is used and wasted during normal functioning.

The Firebird Envirogreen Slimline Combi C26 was given an efficiency rating of 93% and a band rating of "A".

The Energy Related Products Directive (ERP) intends to reduce the amount of energy consumed by individual products over their entire lifetime, from the initial manufacturing process to final disposal and at all points in between.

The legislation is designed to encourage manufacturers to create products that are more environmentally friendly and which result in a reduction in harmful gas emissions.

The ERP rating for the Firebird Envirogreen Slimline Combi C26 is "A" for heat and "A" for hot water production.

Will I be covered if the Firebird Envirogreen Slimline Combi C26 combi breaks down?

The Firebird Envirogreen Slimline Combi C26 boiler comes with a parts and labour warranty lasting 2 years.
