Baxi Duo-tec 33 Combi Gas boiler frequently asked questions

Is the Baxi Duo-tec 33 boiler a combi, regular or a system boiler?

The Baxi Duo-tec 33 may be worth considering if you are looking for a combi boiler for your house or flat.

Traditionally, boilers needed one or more large tanks installed in your property to store their heated water or water that was to be heated later. These tanks were often too large to be practical for most homes so the combi boiler was introduced to Britain in the 1970s by manufacturers to help homeowners overcome this issue.

Instead of using tanks as storage, a combi boiler heats water on demand. It draws water from the mains and heats it instantly on demand before distributing it to wherever it is needed in a property, be it your taps or radiators.

Unfortunately, combi boilers have one main disadvantage for larger properties or larger households. Because they have a maximum volume of water that can be heated on demand at any given time, water pressure, volume and temperature will drop if, for example, someone is taking a shower and another person in your home wants to use a hot water tap at the same time.

Should I install a Baxi Duo-tec 33 combi boiler in my house or flat?

Whether this Baxi Duo-tec 33 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 gas 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 Baxi Duo-tec 33 combi outputs at a maximum of 33 kW, so which types of property would this Baxi Duo-tec 33 Combi boiler be appropriate for?

A Gas Safe boiler installer would say that this Baxi Duo-tec 33 Combi boiler's level of output makes it suitable for installing in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

When choosing a combi boiler like the Baxi Duo-tec 33, you need to consider the "flow rate" as well as the output rate. Flow rates (measured in litres per minute) indicate the volume of hot water that the boiler can heat up and then distribute to your taps and radiators.

However, combi boilers draw water from the mains and this means they can only heat the amount of water that actually enters your property.

What this means is that, if your mains pressure is 12 litres per minute, that is your boiler's effective flow rate even if it has the capacity to process 18 litres per minute. This Baxi Duo-tec 33 Combi boiler's flow rate is 14 L/m.

To give you an idea of the flow rate you might need, a power shower typically requires around 12 litres of water per minute and a basin tap requires 4-8 litres per minute.

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 Baxi Duo-tec 33 have?

The dimensions of the Baxi Duo-tec 33 are 780 mm tall, 450 mm wide, and 345 mm deep.

Is the Baxi Duo-tec 33 a condensing or non-condensing boiler?

We recommend that you select a condensing boiler like the Baxi Duo-tec gas Baxi Duo-tec 33 for your home if possible because of the environmental benefits and the money you'll save on your gas bills.

Condensing boilers are much more energy-efficient than older, non-condensing models as they capture and recycle the heat still present in the water vapour condensation and flue exhaust gases that your boiler creates when burning gas for reuse.

Is the Baxi Duo-tec 33 combi environmentally friendly?

The effects of climate change on the environment are leading many homeowners to question the damage they might be doing by the way they 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 Baxi Duo-tec 33 combi boiler an environmentally friendly choice for your home? Here’s what the figures say.

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 Duo-tec 33 was given an efficiency rating of 92% and a SEDBUK grading of "A".

The ERP (Energy Related Products Directive) applies to all products that consume energy at any time in their lifetime, from manufacture to disposal and all points in between.

This European legislation intends to encourage manufacturers to offer end users products that are better for the environment through the creation of fewer harmful gas emissions at all points of a product's life cycle.

The ERP rating for the Baxi Duo-tec 33 is "A" for heat and "A" for water.

Does a Baxi Duo-tec 33 combi boiler come with a warranty period?

The Baxi Duo-tec 33 boiler is provided with a parts and labour warranty lasting 7 years.

Baxi Duo-tec 33 Combi Gas boiler frequently asked questions

What kind of boiler is the Baxi Duo-tec 33 - standard, combi or system?

If you are searching for a combi boiler for your house or flat, the Baxi Duo-tec 33 is certainly one to consider.

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 gas 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.

Is the Baxi Duo-tec 33 combi boiler from the Duo-tec range a suitable choice 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 Duo-tec 33 combi's output is 33 kW, so which types of property would this Baxi Duo-tec 33 Combi boiler be appropriate for?

Most experienced heating engineers would suggest that the most suitable type of property for installing a Baxi Duo-tec 33 combi boiler in would be medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

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 33 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 33 Combi boiler's flow rate is 14 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.


Where will the Baxi Duo-tec 33 fit in my house?

The Baxi Duo-tec 33's dimensions are 780 mm [H] x 450 mm [W] x 345 mm [D].

Is the Baxi Duo-tec 33 condensing or non-condensing?

The Baxi Duo-tec 33 is a condensing gas boiler - we strongly suggest that you choose either this model or a recently released model if at all possible.

A condensing boiler captures and recycles the warmth present in flue exhaust gases and water vapour condensation created by the burning of gas to warm up the water coming back into your boiler - for example, from your radiators.

Condensing boilers cost less to run (lower gas bills) and are better for the environment.

Is the Baxi Duo-tec 33 combi good for the environment?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.

In Britain's bigger cities, gas boilers, in particular, are responsible for dangerous levels of nitrogen dioxide emissions. Overall, 14% of all of the UK’s greenhouse gas production comes from heating our homes.

Will installing a Baxi Duo-tec 33 combi in your home be a positive contribution to the environment? The figures below will tell you more.

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 Duo-tec 33 was given an efficiency rating of 92% and a SEDBUK grading of "A".

The ERP (or Energy Related Products Directive) is European legislation affecting products that consume energy throughout their lifetime.

The aim is to encourage companies to create environmentally friendlier products that reduce harmful gas emissions during manufacturing and when in use by the end client, right through to their eventual disposal.

In the case of the Baxi Duo-tec 33, the ERP rating is "A" for heat and "A" for hot water production.

How long is the warranty period on a Baxi Duo-tec 33 combi boiler?

The Baxi Duo-tec 33 is supplied with a parts and labour warranty of 7 years.
