Firebird Envirogreen 20 Combi Oil boiler frequently asked questions

Is the Firebird Envirogreen 20 a combi boiler, system boiler or regular boiler?

If you’re looking for a combi boiler for your house or flat, then the Firebird Envirogreen 20 is one you may wish to consider.

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 20 combi boiler suitable for my apartment or house?

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 Firebird Envirogreen 20 combi's output at 20 kW, which types of property would this Firebird Envirogreen 20 Combi boiler be most appropriate for?

A boiler engineer would recommend that, at this level of output, the most suitable type of property for this Firebird Envirogreen 20 Combi boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.

You should also consider a combi boiler's "flow rate" when making your choice.

The flow rate indicates how much water it can take from the mains supply at any one time (measured in litres per minute), which it then heats and distributes to different points in your home like your bathroom, kitchen and radiators. This Firebird Envirogreen 20 Combi boiler's flow rate is 16 L/m.

Combi boilers have no storage tanks like system or heat only boilers. This means that if the water pressure where you live is low, there's no benefit in spending money on a combi with a high flow rate because a high flow rate doesn't mean it can draw any more water from the mains.

In addition, there might be lots of people in your household who want to use hot water at the same time while also having the central heating on. Given that average mains pressure in the UK is between 10 and 12 litres per second and a power shower usually requires about 12 litres of water per minute, a combi boiler might not be the right choice for you and your family.

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 20 size

The Firebird Envirogreen 20 is 845 mm [H] by 595 mm [W] by 614 mm [D] in size.

Many homes in the UK still have floor-standing boilers like the Firebird Envirogreen 20, even though wall-hung boilers have become the product of choice for most homeowners over the last 20 years. If you'd like to replace your existing floor-standing boiler with a compact, wall-mounted boiler to create more space for you and your family, please bear in mind that your pipework may need to be replaced in addition to the cost of the boiler and its installation.

Savings on your oil bills will eventually completely pay for the one-time investment but it will take a few years.

Please be aware that if you replace your existing heat only or system boiler with the Firebird Envirogreen 20, you'll also need to remove your hot water cylinder and/or expansion tank.

Please contact PlumbProud for further advice if you are unsure how to proceed. Our friendly team will be happy to assist you in making the right decision.

Firebird Envirogreen 20 – condensing or non-condensing?

Condensing boilers like the Firebird Envirogreen 20 improve energy efficiency and reduce your annual expenditure on oil.

They do this by capturing and recycling the warmth still present in water vapour condensation and flue exhaust gases to, for example, increase the temperature of the colder water returning from your radiators.

Condensing boilers are also much better for the environment because they emit fewer greenhouse gases.

Is the Firebird Envirogreen 20 combi environmentally friendly?

More and more homeowners are aware of the importance of how we heat our homes and its impact on climate change and other environmental issues.

Central heating systems are responsible for 14% of greenhouse gas emissions in the UK. You may also be aware that the gas boilers we use emit dangerous nitrogen dioxide in large volumes in the bigger British cities.

Do the available figures suggest that installing the Firebird Envirogreen 20 combi in your property would be an environmentally friendly choice?

Boilers manufactured or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to this, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The Firebird Envirogreen 20 has been given a rating of 93% for energy efficiency, equivalent to a SEDBUK "A" rating.

The aim of the Energy Related Products (ERP) Directive is to reduce the harmful gas emissions created during a product’s manufacture and active end use right through to its disposal.

The ERP rating for the Firebird Envirogreen 20 is "A" for heat and "A" for water.

Is there a warranty on the Firebird Envirogreen 20 combi boiler if it breaks down?

The Firebird Envirogreen 20 boiler has a warranty covering parts and labour costs for up to 2 years after installation.

Firebird Envirogreen 20 Combi Oil boiler frequently asked questions

Is the Firebird Envirogreen 20 a standard, combi or system boiler?

If you’re looking for a combi boiler for your house or flat, you may wish to the consider the Firebird Envirogreen 20.

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 oil 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.

Is the Firebird Envirogreen 20 combi suitable for my house or flat?

To determine that, we need to consider the size of the boiler. Size doesn't mean how big the boiler is - it means how big its "output" is.

This Firebird Envirogreen 20 Combi boiler gets its power from oil and the power it's capable of producing is measured in kilowatts - the output rate is actually a kilowatt rate. The higher the output rate, the more kilowatts a boiler can use when heating water.

If you choose a boiler whose output rate is too low, it may not have enough power to make your water as hot as you would like. If you choose a boiler whose output rate is too high, you won't have to put up with lukewarm water but you will face higher oil bills.

The Firebird Envirogreen 20 combi boiler has an output level of 20 kW, so which types of property would it be appropriate for?

A PlumbProud boiler engineer would recommend that this Firebird Envirogreen 20 Combi boiler is suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

Please remember too that all combi boilers draw water from the mains - they have no storage tanks. Combis heat the water from the mains on demand and then send it to wherever it's needed in the house, like a radiator, a bathroom or a kitchen.

The speed at which it can do this is called the "flow rate", which is measured in litres per minute. If you have a lot of radiators and bathrooms in your home and multiple people are regularly trying to use the hot water at one time, such as in the morning or evening, you'll need a combi with a high flow rate. This Firebird Envirogreen 20 Combi boiler's flow rate is 16 L/m.

However, it's not that simple. Combis can only draw water from the mains at the speed it's delivered. If the flow rate of the local water supply is 11l/m, you shouldn't purchase a boiler with a flow rate of 17l/m because it will never be able to use that extra capacity.

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 dimensions does a Firebird Envirogreen 20 have?

The measurements of the Firebird Envirogreen 20 are 845 mm by 595 mm by 614 mm.

There are hundreds of thousands of properties whose central heating systems are powered by floor-standing boilers like the Firebird Envirogreen 20. 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're considering replacing your existing heat only or system boiler with the Firebird Envirogreen 20, you will also need to remove the hot water cylinder and/or expansion tank.

For information and guidance on the best course of action, please contact PlumbProud and we'll share our thoughts.

Is the Firebird Envirogreen 20 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 Firebird Envirogreen 20 for this reason - the more recent your model the better because the technology improves every year.

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

Is the combi Firebird Envirogreen 20 boiler energy efficient?

With growing concern among the public about accelerating climate change, how we heat our homes and the impact this has on the environment has become a major topic of concern for many homeowners.

About 14% of the greenhouse gases we produce in the UK come from the power needed for central heating. In bigger British cities, gas boilers are a significant source of nitrogen dioxide emissions.

Would choosing the Firebird Envirogreen 20 combi help the environment? Let's see what the statistics suggest.

Boilers manufactured after April 2018 in the UK must achieve an "A" on the SEDBUK grading system as well as score a minimum of 92% on a separate energy efficiency test. Prior to that, the minimum was 88% - boilers rated at 88% and 89% were given a “B” rating (90% and higher were given an "A").

An energy efficiency rating describes how much energy the boiler uses and how much it wastes when in use.

The Firebird Envirogreen 20 was awarded an efficiency rating of 93% with a SEDBUK grading of "A".

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 20 has a rating of "A" for heat and "A" for hot water production.

Am I covered if the Firebird Envirogreen 20 combi boiler breaks down?

The Firebird Envirogreen 20 boiler comes with a 2 year warranty for parts and labour.
