Firebird Envirogreen Slimline Combi C26 Combi Oil boiler frequently asked questions

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

Suitable for a house or a flat, the Firebird Envirogreen Slimline Combi C26 combi boiler is worth considering if you want a combi boiler.

In many properties, combi boilers are more suitable than traditional types of boiler. Combi boilers heat water instantly on demand, which they draw directly from the mains supply, removing the need for storage tanks that can take up valuable space in your home.

A combi boiler is often the right choice for a smaller property, particularly if your home doesn't have a useable loft. As water is heated and delivered immediately rather than being kept warm for hours in an immersion tank, combi boilers reduce oil usage, thereby minimising your heating costs.

The main disadvantage of combi boilers is that they can only heat a certain amount of water at any one time. This means that, if two people are using different taps or showers within your home at the same time, the flow of heated water to each will be reduced, as will the water pressure and temperature.

Should I choose a Firebird Envirogreen Slimline Combi C26 combi boiler for my house or flat?

Whether this Firebird Envirogreen Slimline Combi C26 Combi boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions - it means how powerful it is.

The output level of a boiler tells you how much power it has to heat the water coming from your taps and warming up your radiators. The higher the output level, the greater the volume of water it can heat up.

If the output (measured in kilowatts) is too high, you'll pay higher oil bills and your water will be piping hot. Too low and the water coming out of your taps and being fed into your radiators will often be lukewarm.

The Firebird Envirogreen Slimline Combi C26 combi outputs at a maximum of 26 kW, so which types of property would this Firebird Envirogreen Slimline Combi C26 Combi boiler be appropriate for?

A boiler engineer would recommend that, at this level of output, the most suitable type of property for this Firebird Envirogreen Slimline Combi C26 Combi boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.

When choosing a combi boiler for your home, you need to think about "flow rates" as well as output rates. This Firebird Envirogreen Slimline Combi C26 Combi boiler's flow rate is 16 L/m.

This indicates the maximum volume of hot water (measured in litres per minute) that your boiler can heat then distribute to your taps, showers and radiators at any one time. The greater the demand for hot water in your home, the higher the flow rate you will require.

However, all combi boilers like the Firebird Envirogreen Slimline Combi C26 draw water directly from the mains and heat it instantly.

This means that they can only heat and distribute water at the rate it enters the property (the "mains pressure" rate). For example, if your mains pressure is 11 litres per minute, this will be the highest flow rate you can achieve even if your boiler's flow rate is 17l/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

The Firebird Envirogreen Slimline Combi C26 is 855 mm [H] by 520 mm [W] by 600 mm [D] in size.

While a large number of properties in the UK still feature floor-standing boilers like the Firebird Envirogreen Slimline Combi C26, the more compact wall-hung models are now the preferred options for most homeowners keen for more living space for themselves and their families. It is possible to replace your floor-standing unit with a wall-hung and more compact boiler but please note that much of the pipework could need replacing, making the overall cost of installation higher.

Your new compact will save you money on your oil bills every quarter, however, and those savings should cover the costs within a few years.

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 non-condensing or condensing?

The Firebird Envirogreen Slimline Combi C26 is a condensing oil boiler - we’d strongly recommend that you choose the very latest condensing model for your home.

Condensing boilers run on either gas or oil and are manufactured specifically to improve energy efficiency. They do this by capturing and recycling the warmth present in flue exhaust gases and water vapour condensation into more usable heat the system can use, meaning they're far more efficient and cost less to run.

Is the Firebird Envirogreen Slimline Combi C26 combi boiler 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.

Gas boilers are responsible for dangerous atmospheric levels of nitrogen dioxide emissions in Britain's biggest cities and, overall, 14% of the UK’s greenhouse gases are produced by our domestic central heating systems.

Is the Firebird Envirogreen Slimline Combi C26 combi an environmentally friendly choice for your home? Let’s have a look at the figures.

By law, the minimum level of energy efficiency for boilers manufactured in the UK is 92%, equivalent to a good SEDBUK “A” rating. Prior to April 2018, the minimum was 88% - boilers whose energy efficiency levels were 88% or 89% were given a "B" rating on the SEDBUK scale and those at 90% or higher were given an "A".

The energy efficiency rating awarded to each boiler indicates the amount of energy that is wasted when in operation.

Following testing, the Firebird Envirogreen Slimline Combi C26 was given a 93% energy efficiency rating and a SEDBUK grading of "A".

All products that consume energy throughout their lifespan must comply with the Energy Related Products (ERP) Directive.

Companies are legally obliged to reduce harmful gas emissions at all stages of a product's life cycle, from initial manufacturing right through to final disposal as well as when the product is in actual use.

The Firebird Envirogreen Slimline Combi C26 scores "A" for heat and "A" for water.

If the Firebird Envirogreen Slimline Combi C26 combi boiler breaks down, am I covered?

Firebird Envirogreen Slimline Combi C26 Combi Oil boiler frequently asked questions

Firebird Envirogreen Slimline Combi C26 - combi, system or regular boiler?

The Firebird Envirogreen Slimline Combi C26 is a combi boiler you may wish to consider if you want this particular type of boiler for your house or flat.

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

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

Boiler output is measured in kilowatts and tells you how much power a boiler can use to heat the water your taps, showers and radiators need. The higher the output, the more power it has.

When choosing a boiler, you should choose one that can cope with the peak demand for hot water in your home and not just your typical usage.

If its output is too low, sometimes your hot water will not be hot enough, but if your boiler's output is too high for your needs, your oil bills will go up and not down.

The output of the Firebird Envirogreen Slimline Combi C26 combi 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 boiler installers would recommend that this Firebird Envirogreen Slimline Combi C26 Combi boiler would be suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

Please remember to consider "flow rates" as well when choosing your new boiler. All combi boilers including the Firebird Envirogreen Slimline Combi C26 draw water from the mains.

Each combi boiler has its own flow rate (measured in litres per minute) - this tells you how much water it can heat and distribute to your home’s taps and radiators straight from the mains. This Firebird Envirogreen Slimline Combi C26 Combi boiler's flow rate is 16 L/m.

There is no benefit to you in choosing a combi with a high flow rate if your mains pressure is low - save money by buying a boiler whose flow rate is equal to or slightly more than the pressure in your water pipes.

In addition, if you have a lot of radiators and bathrooms in your home or you have a large household that often uses lots of hot water at the same time, like for regular morning and evening showers, a combi boiler may not be suitable.

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 Slimline Combi C26 have?

The Firebird Envirogreen Slimline Combi C26 measures 855 mm tall, 520 mm wide, and 600 mm deep.

Because of their convenient and compact size, wall-hung boilers have become the popular choice for homeowners over the last 20 years. Yet while hundreds of thousands of UK properties still use floor-standing boilers like the Firebird Envirogreen Slimline Combi C26, many consider switching to wall-mounted units to create extra living space.

We can replace your floor-standing boiler if you wish but there may be an additional cost if we have to replace much of your existing pipework. The savings you make on your oil bills every quarter should repay that investment within a few years.

Please also note that if you’re choosing to replace an existing heat only or system boiler with the Firebird Envirogreen Slimline Combi C26, you will need to budget for the removal of your hot water cylinder and/or expansion tank.

Please contact PlumbProud for professional information and guidance on the best course of action and we’ll share our advice with you.

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

We recommend that, if possible, you choose a condensing boiler like the Firebird Envirogreen Slimline Combi C26.

Condensing boilers are more energy-efficient. They achieve this efficiency by capturing the heat present in flue exhaust gases and water vapour condensation and recycling that heat to, for example, warm colder water coming back from your radiators.

By choosing the latest condensing boiler, you'll also notice a significant reduction in your oil bills, particularly if you're replacing a boiler more than 15 years old.

Does the Firebird Envirogreen Slimline Combi C26 combi protect the environment?

With more and more of us concerned about environmental issues and climate change, how we heat our homes has become an important issue to 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.

Let's take a closer look at whether installing a Firebird Envirogreen Slimline Combi C26 combi would be a good choice for the environment.

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 Firebird Envirogreen Slimline Combi C26 was rated at 93% with a SEDBUK grading of "A".

Energy-efficient boilers help the environment as they require less fuel and emit fewer harmful gases. In 2015, the EU introduced the Energy Related Products Directive (ERP), the aim of which was to ensure that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

The legislation aims to conserve energy at all life cycle stages from initial production to actual use by the customer, through to the point of disposal.

The Firebird Envirogreen Slimline Combi C26 has been given an ERP rating of "A" for heat and "A" for water.

What length of warranty does the Firebird Envirogreen Slimline Combi C26 come with?

Parts and labour charges incurred for repairs made to your new Firebird Envirogreen Slimline Combi C26 are covered by a 2 year warranty.
