Firebird Enviromax Blue Supreme Slimline 20 heat only Oil boiler frequently asked questions

What type of boiler is Firebird’s Enviromax Blue Supreme Slimline 20 - system, regular or combi?

You may wish to consider installing the Firebird Enviromax Blue Supreme Slimline 20 if you are looking for a heat only boiler for your house or flat.

You may hear a heat only boiler described as a standard boiler, a regular boiler, or a conventional boiler but the terms mean the same. Heat only boilers require a hot water cylinder (usually stored in a landing or airing cupboard) and a cold water storage tank (usually stored in the loft) to operate. Your water is kept warm by the hot water cylinder throughout the day.

A heat only boiler lets you schedule the hot water and central heating you want for set times of the day. However, you'll have to wait before having a bath or shower if you forget to set it and there's no hot water left in the tank.

If you have a bigger family or more than one bathroom, a heat only boiler is a better option than a combi boiler in many cases. This is because a combi boiler struggles to maintain water volume, pressure and temperature to multiple points in a home simultaneously.

Is the Firebird Enviromax Blue Supreme Slimline 20 heat only boiler a suitable option for my house or flat?

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

Your boiler’s output is a measurement of the power it has available to heat the volume of water required for your taps and radiators. The higher the output rate, the more water it can heat.

You need to be careful to select a boiler with the optimal level of output for your property though. That's because, if your boiler output is too low, your water and radiators will often not be as hot as you want them to be. If the output is too high, you’ll be paying more for oil than you need to.

The output of the Firebird Enviromax Blue Supreme Slimline 20 heat only is 20 kW, so which types of property would this Firebird Enviromax Blue Supreme Slimline 20 heat only boiler be appropriate for?

An experienced Gas Safe boiler installer would recommend that the Firebird Enviromax Blue Supreme Slimline 20 heat only boiler would be an ideal installation option for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


Firebird Enviromax Blue Supreme Slimline 20 dimensions

The Firebird Enviromax Blue Supreme Slimline 20 occupies a space of TBC mm high by TBC mm wide and TBC mm deep.

If you want to replace your floor-standing boiler with a more compact, wall-mounted model, this will give you and your family more space. Hundreds of thousands of homes in the UK still use floor-standing boilers like the Firebird Enviromax Blue Supreme Slimline 20, but wall-mounted models have been the most popular choice for homeowners over the last two decades. We can replace your floor-mounted unit with a wall-mounted unit, but please be aware that the cost of installation will be higher if we need to replace your current piping.

However, you can recoup this investment in full over a few years with the savings you make on your oil bills.

Is the Firebird Enviromax Blue Supreme Slimline 20 a condensing or non-condensing boiler?

The Firebird Enviromax Blue Supreme Slimline 20 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 Enviromax Blue Supreme Slimline 20 heat only considered 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.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

Will installing a Firebird Enviromax Blue Supreme Slimline 20 heat only be a positive contribution to the environment? Let's see what the experts say.

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 Enviromax Blue Supreme Slimline 20 is rated as 97.4% energy efficient, equivalent to a "A" SEDBUK rating.

In 2015, new legislation was introduced by the EU to encourage manufacturers to develop more energy-efficient products that emit fewer harmful gases throughout their lifetime.

The Energy Related Products Directive (ERP) applies to all products that consume energy, including during the manufacturing process, at the point of final disposal, and all points in between.

The ERP rating of the Firebird Enviromax Blue Supreme Slimline 20 is "A".

How many years' warranty does the Firebird Enviromax Blue Supreme Slimline 20 heat only come with?

The Firebird Enviromax Blue Supreme Slimline 20 boiler comes with a 2 year warranty for parts and labour.

Firebird Enviromax Blue Supreme Slimline 20 heat only Oil boiler frequently asked questions

Firebird Enviromax Blue Supreme Slimline 20 - a regular boiler, combi boiler or system boiler?

When looking for a heat only boiler for your house or flat, the Firebird Enviromax Blue Supreme Slimline 20 might be a suitable option for you.

You can program a heat only boiler (sometimes called a standard boiler, a regular boiler or a conventional boiler) to provide hot water and heating at particular times of the day. Heat only boilers consist of a cold water tank (often housed out of sight in the loft), a hot water cylinder with an immersion heater (normally situated in an airing or landing cupboard), and a control panel.

Regular boilers are best suited for large households with many members, at least two of whom often need hot water at the same time.

Is the Firebird Enviromax Blue Supreme Slimline 20 heat only boiler a suitable option for my house or flat?

Whether this Firebird Enviromax Blue Supreme Slimline 20 heat only boiler is right for your property depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output rating indicates how much energy a boiler can use in providing you with hot water and heat when you need it from your radiators and taps. The greater the output, the more water it can heat.

It's better to take advice on this from a registered installer because, if your boiler output is too low, your water and radiators might not get as hot as you would like them to be. However, if the output level is too high, you'll end up paying more on your oil bills than you need to.
