Baxi Duo-tec 40 Combi Gas boiler frequently asked questions

Is the Baxi Duo-tec 40 a combi, system or regular boiler?

The Baxi Duo-tec 40 boiler could be suitable for your house or flat if you are looking for a new combi boiler.

Traditional boilers often have up to two tanks that either store heated water or water to be heated later. Boiler manufacturers introduced combi boilers in the 1970s to avoid the need for those big tanks. Combi boilers allow homeowners to benefit from the reliable central heating and hot water level they want but without having to give up so much space within their properties - remember that homes in the UK are among the smallest in the developed world.

Your taps and radiators get the hot water they need with a combi boiler. Combi boilers draw cold water direct from the mains which is then heated instantly on demand and distributed to your radiators and taps.

However, combi boilers cannot heat very large volumes of water, which is their main disadvantage. So, for example, when someone wants to take a shower while another person wants to use a hot water tap to do the dishes, water pressure and quantity to both points decreases.

Would the Baxi Duo-tec 40 combi be a suitable boiler for my house or flat?

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

Your boiler’s output is a measurement of the power it has available to it to heat the water you need for your radiators or for when you turn on a tap, bath or shower. A higher output rate means it has more power and can heat more water.

It's important to choose an output that matches the demand for water in your home because if your boiler has too low an output, you'll often find only lukewarm water comes out of your taps or heats your radiators. If it’s too high, you’ll be paying more for your gas than you need to.

The Baxi Duo-tec 40 combi has an output of 40 kW, so which types of property would this Baxi Duo-tec 40 Combi boiler be appropriate for?

An experienced Gas Safe boiler installer would be likely to recommend that this Baxi Duo-tec 40 Combi boiler is capable of providing heating and hot water to 15 or more radiators and two or more bathrooms and would therefore be most suitable for larger properties including detached homes.

With all combi boilers, you need to consider the "flow rate" as well as the output rate when making your decision.

Like all combi boilers, the Baxi Duo-tec 40 draws water from the mains. It instantly heats that water and then distributes it to the parts of your home which need it - taps, radiators, bathrooms, and so on. This Baxi Duo-tec 40 Combi boiler's flow rate is 16 L/m.

There is no benefit to purchasing a boiler with a high flow rate if the local water pressure is not that good - a high flow rate doesn't mean that your combi can draw more water from the mains.

In addition, if you live in a home with a large number of radiators and more than one bathroom and if more than one person regularly wants to use hot water at a time, a combi boiler may struggle to provide enough water at a hot enough temperature.

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.


The size of the Baxi Duo-tec 40

The dimensions of the Baxi Duo-tec 40 are 780 mm [H] x 450 mm [W] x 345 mm [D].

Is the Baxi Duo-tec 40 a condensing or non-condensing boiler?

We recommend the Baxi Duo-tec 40 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 the Baxi Duo-tec 40 combi boiler environmentally friendly?

How we heat our homes has become a major issue for many people worried about climate change and environmental issues in general.

About 14% of the greenhouse gases we produce in the UK come from the power needed for central heating. In bigger British cities, gas boilers are a significant source of nitrogen dioxide emissions.

Would installing a Baxi Duo-tec 40 combi boiler in your home be a green choice? Let's look at the numbers.

The Baxi Duo-tec 40 has been awarded an efficiency rating of 92% and a SEDBUK band rating of "A".

In the UK, all boilers manufactured and supplied must have an energy efficiency rating of at least 92% or a SEDBUK "A" grade. Until April 2018, the minimum rating was 88% (88% and 89% are equivalent to a SEDBUK "B" rating and anything higher is rated "A").

A boiler's energy efficiency rating describes the amount of energy it uses and wastes when in normal operation.

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 Baxi Duo-tec 40 has been given an ERP rating of "A" for heat and "A" for water.

What is the length of the warranty on the Baxi Duo-tec 40?

The Baxi Duo-tec 40 is supplied with a parts and labour warranty of 7 years.

Baxi Duo-tec 40 Combi Gas boiler frequently asked questions

Is the Baxi Duo-tec 40 boiler a combi, regular or a system boiler?

If you want a combi boiler for your flat or house, the Baxi Duo-tec 40 might be an option for you to consider.

Traditional boilers need one or more large tanks to work - one to heat and keep water warm for immediate use and the other to store water intended for heating later. Finding space for these large tanks is difficult in British residential property - remember that our houses and flats are among the smallest in the world. This is the problem that combi boilers were designed to solve when they were introduced in the 1970s.

Combi boilers don't need a tank - instead, they instantly heat water drawn from the mains using technology inside the boiler. This hot water is then distributed immediately to your taps or radiators on demand.

The biggest disadvantage to combi boilers is that they have a maximum capacity for heating water, meaning that they work best when only one point within a household wants hot water. For example, if someone is taking a shower and another person uses a hot water tap at the same time, the water pressure, volume and temperature to both points drops.

Is a Baxi Duo-tec 40 combi boiler suitable for my apartment or house?

It's best to choose a boiler whose size or "output" is right for your property. With boilers, however, size does not mean how big a boiler is, it means how much power it has.

A boiler’s output indicates the amount of power it can use when heating the water which it then sends to your taps and radiators. The higher the output rate, the more water it can heat.

If a boiler’s output is too low, there will be times when your hot water might not be as hot as you want it to be. If it is too high, you’ll likely be paying more than you need to for your gas.

Measured in kilowatts, the Baxi Duo-tec 40 combi's output level is 40 kW, so which types of property would this Baxi Duo-tec 40 Combi boiler be an appropriate choice for?

An experienced PlumbProud Gas Safe boiler installer would almost certainly recommend that this Baxi Duo-tec 40 Combi boiler would be most suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

With combi boilers like the Baxi Duo-tec 40, 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 Baxi Duo-tec 40 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 is the size of the Baxi Duo-tec 40?

The Baxi Duo-tec 40 is 780 mm high by 450 mm wide by 345 mm deep.

Is the Baxi Duo-tec 40 a condensing or non-condensing boiler?

We recommend that you choose a condensing boiler wherever possible like the Baxi Duo-tec 40 - try to go for the latest model, if possible, to take advantage of improving technology.

Condensing boilers capture and recycle the warmth still present in the water vapour condensation and in flue exhaust emissions created by burning gas to make them more efficient and economical to run.

You will save money on your gas bills too, plus condensing boilers are friendlier to the environment.

Is the Baxi Duo-tec 40 combi good for the environment?

More and more homeowners are aware of the importance of how we heat our homes and its impact on climate change and other environmental issues.

With central heating being responsible for 14% of greenhouse gas emissions in the UK, your choice of boiler matters. Gas boilers are also responsible for the significant atmospheric volumes of dangerous nitrogen dioxide emissions in larger British cities.

Would the environmental impact of installing a Baxi Duo-tec 40 combi in your home be positive? Let's look at the numbers.

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 Baxi Duo-tec 40 was given an efficiency rating of 92% 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 Baxi Duo-tec 40 is "A" for heat and "A" for water.

Does the Baxi Duo-tec 40 combi boiler come with a warranty?

The Baxi Duo-tec 40 is supplied with a parts and labour warranty of 7 years.
