Baxi EcoBlue 21 heat only Gas boiler frequently asked questions

Is the Baxi EcoBlue 21 boiler a combi, system or regular boiler?

If you’re looking for a heat only boiler for your house or flat, then the Baxi EcoBlue 21 is one you may wish to consider.

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 Baxi EcoBlue 21 heat only boiler a suitable option for my house or flat?

It's best to choose a boiler whose size or "output" is right for your home.

The more hot water and heat you want, the higher the output level of your boiler should be. Output is measured in kilowatts and it describes the maximum level of power your boiler has to heat water.

If your output level is too low, your boiler will not have the power it needs to get your water as hot as you want it, particularly when there's a lot of demand for it. Choose a boiler whose output level is too high and you'll have all the hot water you need but will be paying too much for it through higher gas bills.

Which types of property would this Baxi EcoBlue 21 heat only boiler be appropriate for given its output of 21 kW?

A Gas Safe boiler installer would say that this Baxi EcoBlue 21 heat only boiler's level of output makes it suitable for installing in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


The size of the Baxi EcoBlue 21 in millimetres

The Baxi EcoBlue 21 is 625 mm in height, 370 mm in width and 270 mm in depth.

Is the Baxi EcoBlue 21 condensing or non-condensing?

The Baxi EcoBlue 21 is a condensing boiler – we recommend to all clients that they choose the very latest condensing boilers because their efficiency continues to improve year after year.

Condensing boilers recycle heat from both water vapour condensation and flue exhaust gases via a secondary heat exchanger. With this heat, it performs other tasks like warming up colder water returning from your radiator without having to use more gas.

You will save money on your gas bills every year by choosing a condensing boiler as well as benefitting the environment.

Is the Baxi EcoBlue 21 heat only environmentally friendly?

How we heat our homes is an issue which many homeowners worry about as the world combats climate change and environmental damage.

Approximately 14% of the UK's greenhouse gas production is caused by our central heating systems. The gas boilers in larger urban areas of Britain are mainly responsible for emissions of toxic nitrogen dioxide.

Is the Baxi EcoBlue 21 heat only an environmentally friendly choice for your home? Let’s have a look at the figures.

All boilers manufactured and installed in the UK are required to have an energy efficiency rating of 92% or above (or a good “A” SEDBUK rating). Before April 2018, when the law changed, the minimum energy efficiency level permissible was 88% (86-90% is a SEDBUK "B" rating and 90%+ is an "A" rating).

A boiler's energy efficiency rating indicates the amount of energy used and wasted during normal operational performance.

Following its assessment, the Baxi EcoBlue 21 was given an efficiency rating of 89.2% and a SEDBUK grading of "B".

The Energy Related Products (ERP) Directive's aim 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 Baxi EcoBlue 21 is "TBC".

How long is the warranty offered by the manufacturer for the Baxi EcoBlue 21 boiler?

Parts and labour charges incurred for repairs made to your new Baxi EcoBlue 21 are covered by a 2 year warranty.

Baxi EcoBlue 21 heat only Gas boiler frequently asked questions

Baxi EcoBlue 21 - combi, system or regular boiler?

If you are searching for a heat only boiler for your house or flat, the Baxi EcoBlue 21 is certainly one to consider.

Heat only boilers (often referred to as conventional boilers, standard boilers or regular boilers) consist of a large cold water tank, hot water cylinder with an immersion heater, and a control panel. The cold water tank is often situated in a loft or attic while the hot water cylinder tends to be located in an airing or landing cupboard.

The major advantage of a heat only boiler compared to the more contemporary combi boiler is that it’s possible to run more than one appliance requiring hot water at the same time. With a combi boiler, switching two hot water taps on at the same time will lead to a drop in water pressure, temperature and volume to both points.

Best suited for larger homes, you can program hot water and central heating for times and days that suit you and your family. However, if you forget to set the timer and your hot water cylinder is empty, then you may have to wait up to an hour before you run a bath.

Would the Baxi EcoBlue 21 heat only be a suitable choice of boiler for my house or flat?

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.

The output rate of a boiler tells you how much power it has available to it for heating the water that comes out of your taps and warms your radiators. A higher output rate means that your boiler has more power at its disposal.

You need to make sure you select a boiler with the right output rate. That's because, if your output rate is too high, then your boiler will have more power than it needs but it will cost too much to run. If the output rate is too low, your water may often not be hot enough.

The Baxi EcoBlue 21 heat only's output is 21 kW, so which types of property would this Baxi EcoBlue 21 heat only boiler be appropriate for?

Most experienced Gas Safe boiler installers would suggest that the Baxi EcoBlue 21 heat only boiler would be a suitable choice for installation in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


What are the proportions of a Baxi EcoBlue 21 boiler?

The Baxi EcoBlue 21 boiler is 625 mm high, 370 mm wide, and 270 mm deep.

Is this Baxi boiler non-condensing or condensing?

We recommend the Baxi EcoBlue 21 as it is a modern condensing gas boiler from a trusted manufacturer with a reputation for supplying highly energy-efficient boilers.

Condensing boilers capture the heat still present in water vapour condensation and flue exhaust gases and recycle it back into the heating system. With this extra energy, your boiler can, among other tasks, reheat colder water coming back from your radiators without having to burn more gas.

Condensing boilers significantly reduce your quarterly gas costs and they're better for the environment.

Is choosing the Baxi EcoBlue 21 heat only boiler environmentally friendly?

Price and performance are two important issues when choosing a boiler but now, for many people in the UK, so is the environmental impact of how we heat our homes and its effect on climate change.

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

Would choosing the Baxi EcoBlue 21 heat only help the environment? Let's see what the statistics suggest.

In the UK, by law, all boilers manufactured since April 2018 must have a SEDBUK “A” rating and operate to a minimum level of 92% energy efficiency. Prior to this, the minimum was 88% – 88/89% would score a "B" and 90% or more an "A" on the SEDBUK scale.

The energy efficiency rating measures the amount of energy a boiler consumes when it's in use and how much it loses on non-core operations.

Following testing, the Baxi EcoBlue 21 was given an efficiency rating of 89.2% and a SEDBUK grading of "B".

The Energy Related Products Directive grades products according to the energy they consume and the harmful gas emissions they create, from manufacturing right through to final disposal, including how they're used by customers between these two points.

The Baxi EcoBlue 21 is rated "A".

How long is the warranty period on the Baxi EcoBlue 21 heat only boiler?

You receive a parts and labour warranty of 2 years with the Baxi EcoBlue 21 boiler.
