Which category of boiler does the Baxi EcoBlue Advance 40 fit into?

Looking for a gas combi boiler for your house or flat? If you are, the Baxi EcoBlue Advance 40 boiler may be worth considering.

Traditionally, most boilers required you to find space in your property for one or more large storage tanks. These tanks would either keep water warm or hold it in reserve for later heating. Manufacturers originally introduced combi boilers to offer homeowners the same level of warmth and hot water without taking up as much space – remember that the UK has some of the smallest homes in the Western world.

With a combi boiler, the hot water needed for your radiators and taps is provided on demand. Water from the mains passes through your combi boiler and the technology within it instantly heats the cold water. It then distributes that hot water around your home.

The biggest drawback for combi boilers is that they have a maximum capacity in volume for heating water. This means that if someone wants to use the shower while another person wants to use a hot water tap, the amount of water reaching each point falls, resulting in a drop in water pressure.

Is the Baxi EcoBlue Advance 40 combi boiler suitable for my house or apartment?

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 Advance 40 Combi boiler be appropriate for given its output of 40 kW?

Most experienced Gas Safe engineers would likely recommend that, at this level of output, this Baxi EcoBlue Advance 40 Combi boiler would be a suitable choice for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

Please remember too that all combi boilers draw water from the mains - they have no storage tanks. Combis heat the water from the mains on demand and then send it to wherever it's needed in the house, like a radiator, a bathroom or a kitchen.

The speed at which it can do this is called the "flow rate", which is measured in litres per minute. If you have a lot of radiators and bathrooms in your home and multiple people are regularly trying to use the hot water at one time, such as in the morning or evening, you'll need a combi with a high flow rate. This Baxi EcoBlue Advance 40 Combi boiler's flow rate is 16 L/m.

However, it's not that simple. Combis can only draw water from the mains at the speed it's delivered. If the flow rate of the local water supply is 11l/m, you shouldn't purchase a boiler with a flow rate of 17l/m because it will never be able to use that extra capacity.

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.

Baxi EcoBlue Advance 40 size

The dimensions of the Baxi EcoBlue Advance 40 are 763 mm [H] x 450 mm [W] x 345 mm [D].

EcoBlue Advance 40 – condensing or non-condensing?

We recommend that, if possible, you choose a condensing boiler like the Baxi EcoBlue Advance 40.

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 gas bills, particularly if you're replacing a boiler more than 15 years old.

Is choosing the Baxi EcoBlue Advance 40 combi boiler environmentally friendly?

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.

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.

Let's take a closer look at whether installing a Baxi EcoBlue Advance 40 combi would be a good choice for the environment.

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 Baxi EcoBlue Advance 40 is rated as 93% energy efficient, equivalent to a "A" SEDBUK rating.

The Energy Related Products (ERP) directive is Europe-wide legislation designed to reduce harmful gas emissions at all points of a product's life cycle - from the production process to its actual end use, right through to final disposal.

The Baxi EcoBlue Advance 40 has a rating of "A" for heat and "A" for water.

How many years' warranty does the Baxi EcoBlue Advance 40 combi come with?

The Baxi EcoBlue Advance 40 boiler comes with a parts and labour warranty of 10 years.
