Firebird Envirogreen Combipac C20 Combi Oil boiler frequently asked questions

Is this Firebird Envirogreen Combipac C20 boiler a combi, system or regular boiler?

Firebird’s Envirogreen Combipac C20 is one you might consider if you’re looking for a combi boiler for your house or flat.

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.

Should I install a Firebird Envirogreen Combipac C20 combi boiler in my house or apartment?

You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".

Your boiler should be able to cope with peak hot water demand in your property and not just your average hot water usage. The output rate of a boiler is measured in kilowatts and tells you how much power a boiler can use to provide hot water to your taps, showers and radiators.

If the output of your boiler is too low, there will often be times when your water isn't as hot as you want. But if your boiler output is too high, it will be more costly to run (often unnecessarily).

The output of the Firebird Envirogreen Combipac C20 combi boiler is 20 kW kilowatts. Which types of property would this be appropriate for?

A Gas Safe boiler installer would recommend that this Firebird Envirogreen Combipac C20 Combi boiler would provide adequate heating and hot water for smaller homes and apartments with up to up to 10 radiators and one bathroom.

Flow rates are important when choosing a combi boiler as well as output rates.

A combi boiler's flow rate (measured in litres per minute) describes how much water it can instantly heat then distribute to the taps and radiators in your home - you will need to factor this into your decision on a new combi boiler. This Firebird Envirogreen Combipac C20 Combi boiler's flow rate is 16 L/m.

If you have a lot of radiators and bathrooms in your home and there's lots of demand within your household for hot water at the same time (like morning or evening showers and baths), you'll need a boiler with a high flow rate.

However, it's not quite that simple. If your local mains water pressure is low, you're not going to gain any benefit from choosing a combi boiler with a high flow rate because that higher flow rate doesn't mean it can draw more water from the mains pipes.
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 Combipac C20 - size in millimetres

The Firebird Envirogreen Combipac C20 is 945 mm tall, 720 mm wide, and 625 mm deep in size.

There are several benefits to choosing an external, floor-standing combi boiler like the Firebird Envirogreen Combipac C20. External boilers free up space indoors and reduce internal noise pollution to almost zero. They are also easier for an engineer to access if a problem develops and an external boiler reduces the chances of carbon monoxide leaking into your property.

External boilers are fitted in weatherproof housing and are perfect for homes that require oil-fired heating because they are not connected to mains gas. Leakage is always a possibility with oil boilers but, as this Firebird Envirogreen Combipac C20 Combi boiler is fitted outside your home, there is likely to be much less damage to your property if it leaks and no odour of oil in your home.

Is the Firebird Envirogreen Combipac C20 non-condensing or condensing?

This Firebird Envirogreen Combipac C20 is a condensing oil boiler - we always recommend that clients choose the latest condensing models to benefit from the technology, which continues to improve year after year.

Condensing boilers capture the heat still present in flue exhaust gases and water vapour condensation, processing them through a secondary heat exchanger to, among other tasks, heat colder water returning from your radiators.

By selecting a modern condensing boiler, you'll save money on your oil bills as well as benefitting the wider environment.

Is the combi Firebird Envirogreen Combipac C20 boiler energy efficient?

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.

14% of the UK’s greenhouse gas production comes from central heating. In the bigger cities, gas boilers in particular are responsible for dangerous levels of nitrogen dioxide emissions.

Let's take a closer look at whether installing a Firebird Envirogreen Combipac C20 combi would be a good choice for the environment.

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 Combipac C20 was given an efficiency rating of 93% and a band rating of "A".

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

Its purpose is to encourage manufacturers to offer products that are kinder to the environment by reducing harmful gas emissions at all stages, from production and end use right through to disposal.

The ERP rating for the Firebird Envirogreen Combipac C20 is "A" for heat and "A" for water.

What warranty do I get if I purchase the Firebird Envirogreen Combipac C20 boiler?

You receive a parts and labour warranty of 2 years with the Firebird Envirogreen Combipac C20 boiler.

Firebird Envirogreen Combipac C20 Combi Oil boiler frequently asked questions

Is the Firebird Envirogreen Combipac C20 a system boiler, a combi boiler or a regular boiler?

Firebird’s Envirogreen Combipac C20 is one you might consider if you’re looking for a combi boiler for your house or flat.

Traditionally, boilers needed one or more large tanks installed in your property to store their heated water or water that was to be heated later. These tanks were often too large to be practical for most homes so the combi boiler was introduced to Britain in the 1970s by manufacturers to help homeowners overcome this issue.

Instead of using tanks as storage, a combi boiler heats water on demand. It draws water from the mains and heats it instantly on demand before distributing it to wherever it is needed in a property, be it your taps or radiators.

Unfortunately, combi boilers have one main disadvantage for larger properties or larger households. Because they have a maximum volume of water that can be heated on demand at any given time, water pressure, volume and temperature will drop if, for example, someone is taking a shower and another person in your home wants to use a hot water tap at the same time.

Should I install a Firebird Envirogreen Combipac C20 combi boiler in my house or apartment?

Selecting the right boiler for your property means selecting a boiler that is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - its "output".

The output rate tells you how much energy your boiler has to use to provide you and your family with hot water and central heating. A higher output rate means that it can heat greater volumes of water.

Please be aware, though - if you choose a boiler whose output is too low, the water in your radiators and coming from your taps may not be warm enough. Conversely, if you choose a boiler with too high an output, you'll pay more for oil than is necessary.

The Firebird Envirogreen Combipac C20 combi boiler has an output level of 20 kW, so which types of property would it be appropriate for?

A PlumbProud heating engineer would recommend that this Firebird Envirogreen Combipac C20 Combi boiler is suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

With combi boilers like the Firebird Envirogreen Combipac C20, you need to take the flow rate into account as well as the output rate.

Combi boilers draw water from the mains and then instantly heat that water and send it to wherever in your home it's needed. Flow rates, measured in litres per minute, are subject to the mains water pressure in your area. So, for example, if the local mains water pressure is 11 litres per minute and the flow rate of your boiler is 14 litres per minute, the boiler will not be able to process more than 11 litres per minute. The flow rate of this Firebird Envirogreen Combipac C20 Combi boiler is 16 L/m.

If you live in a home with lots of radiators or bathrooms where many people want to use hot water at the same time, a combi boiler may not be able to cope. For reference, a power shower uses about 10 litres of water per minute. If two people want showers at the same time or one person wants a shower and the other hot water from a tap in the kitchen, your boiler may not have a large enough flow rate even if the local mains water pressure is high.

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 are the dimensions of the Firebird Envirogreen Combipac C20 boiler?

The Firebird Envirogreen Combipac C20 measures 945 mm in height and has a width of 720 mm and a depth of 625 mm.

4% of the British population rely on oil-powered boilers for hot water and central heating - the Firebird Envirogreen Combipac C20 is an external, floor-standing combi boiler which runs on oil.

For homeowners concerned about the possibility of oil leakages inside their homes, external boilers provide protection against both indoor oil damage from leakage and the unpleasant and hard-to-shift odours those leaks create. They are supplied with weatherproof housing so can function in all weathers, and they're also much easier for a service engineer to work on.

Is the Firebird Envirogreen Combipac C20 condensing or non-condensing?

Condensing boilers like the Firebird Envirogreen Combipac C20 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.

What energy efficiency ratings have been awarded to the Firebird Envirogreen Combipac C20 combi?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.

Nitrogen dioxide emissions in Britain's largest cities are at dangerous levels and this has been caused by gas boilers. In fact, 14% of the UK’s greenhouse gases are produced by central heating.

Is the Firebird Envirogreen Combipac C20 combi an environmentally friendly choice for your home? Let’s have a look at the figures.

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 Firebird Envirogreen Combipac C20 was awarded an efficiency rating of 93%, equivalent to a SEDBUK grade of "A".

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

Its purpose is to encourage manufacturers to offer products that are kinder to the environment by reducing harmful gas emissions at all stages, from production and end use right through to disposal.

The ERP rating for the Firebird Envirogreen Combipac C20 is "A" for heat and "A" for water.

If the Firebird Envirogreen Combipac C20 breaks down, will I be covered by the warranty?

The Firebird Envirogreen Combipac C20 is supplied with a parts and labour warranty of 2 years.
