Product Description

The Envirogreen System C20 is a highly reliable internal oil boiler, designed and manufactured by Firebird.

How efficient is the Envirogreen System C20?

The Envirogreen System C20 is a highly efficient boiler as shown by its 92.5% efficiency rating and ErP A-rating.

Where can this boiler be installed?

Firebird have designed this boiler to be installed in a kitchen or utility room. It’s a floor-standing unit that can fit underneath a standard kitchen worktop, helping to save you some much needed space around the home.

Will this size boiler suit my home?

An output rating of 20kW makes the Envirogreen C20 best suited to smaller homes with 1 bathroom and not such an excessive need for heating and hot water.

What options does this boiler come with?

As well as this 20kW model, the Envirogreen System range also includes boilers with output ratings of 26 kW, 35 kW and 44 kW. As well as the range of outputs, an external unit is also available, if you’re looking to save space around the home, plus you can also take your pick of combi and regular systems too.

Will the Envirogreen C20 save me money?

Thanks to being highly efficient, the Envirogreen C20 will help to keep your energy bills as low as possible. In addition, its compact size makes installation that bit easier which will help to save you money too. Also, front servicing access will keep the price of servicing and repairs down too.

Is a system boiler suitable for my home?

System boilers send hot water to the radiators and a sealed hot water storage cylinder with the important parts of the system being built into the boiler, making it more compact and easier to service than a regular boiler.

What are the key features of the Envirogreen system?

Some of the many features of the Firebird boiler include a low NOx and blue flame option, a fully insulated and acoustic design for ultra quiet operation, a durable casing with a high quality finish, PCB controller, highly accurate thermistor with anti-cycling functions, a patented heat exchanger design, factory-fitted expansion vessel and circulating pump and a low pressure switch to protect the boiler in the unlikely event of system water loss.

Does this boiler come with a warranty?

Firebird boilers are covered with a standard 2 year warranty, so you can have peace of mind that you are getting a highly reliable unit that won’t let you down. There’s also the option to upgrade your warranty to up to 10 years for increased cover.
