Baxi Platinum+ 40 Combi Gas boiler frequently asked questions

Is the Baxi Platinum+ 40 boiler a standard, combi or system model?

If you are considering installing a combi boiler in your house or flat, then the Baxi Platinum+ 40 boiler is certainly worth investigating.

The UK has some of the smallest homes in the Western world, which is partly why combi boilers were introduced in the 1970s. Traditional boilers require one or more large storage tanks which they use to either heat water and keep it warm or store water intended for heating later. These tanks took up a lot of space in people's homes.

Combi boilers save space because they don't require these tanks to operate. Instead, combis draw water direct from your mains supply then instantly heat and distribute it on demand.

The biggest disadvantage in using combi boilers is that they have a maximum capacity volume for heating water. While this may not be an issue in a small household, it could be for a larger household where there is higher demand for hot water. When more than one person is using the water, it is distributed between the two points, reducing the pressure and temperature at each point.

Is the Baxi Platinum+ 40 combi boiler suitable for my house or apartment?

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

The output rate tells you how much energy your boiler has to use to provide you and your family with hot water and central heating. A higher output rate means that it can heat greater volumes of water.

Please be aware, though - if you choose a boiler whose output is too low, the water in your radiators and coming from your taps may not be warm enough. Conversely, if you choose a boiler with too high an output, you'll pay more for gas than is necessary.

The Baxi Platinum+ 40 combi boiler has an output level of 40 kW, so which types of property would it be appropriate for?

A Gas Safe boiler installer would recommend that this Baxi Platinum+ 40 Combi boiler would be a suitable choice for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

With combi boilers like the Baxi Platinum+ 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 Platinum+ 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 Platinum+ 40?

The size of the Baxi Platinum+ 40 boiler is 700 mm high, 390 mm wide, and 285 mm deep.

Is the Baxi Platinum+ 40 condensing or non-condensing?

We recommend the Baxi Platinum+ 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 Platinum+ 40 combi boiler 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.

Around 14% of the greenhouse gases produced in the UK is a result of our central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in some of our largest cities.

Would choosing the Baxi Platinum+ 40 combi help the environment? Let's see what the statistics suggest.

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 Platinum+ 40 was given an efficiency rating of 93% and a SEDBUK grading of "A".

The Energy Related Products (ERP) Directive is important European legislation that aims to limit energy use and harmful gas emissions during the manufacturing process, when the product is in use, and after it is disposed of.

For the Baxi Platinum+ 40, the ERP Heat rating is "A" and the ERP Water rating is "A".

What warranty do I get if I purchase the Baxi Platinum+ 40 boiler?

The Baxi Platinum+ 40 is covered by a parts and labour warranty of 5 years following installation.

Baxi Platinum+ 40 Combi Gas boiler frequently asked questions

Is the Baxi Platinum+ 40 boiler a combi, system or regular boiler?

If you’re looking for a combi boiler for your house or flat, then the Baxi Platinum+ 40 is one you may wish to consider.

Combination or combi boilers are highly efficient and save a lot of space in your home. Combi boilers heat water directly from the mains when you turn on a tap and, as a result, you don’t need a hot water storage cylinder or a cold water tank in the roof space.

These boilers are, therefore, suitable for smaller homes and especially those without a loft. They are also cost-effective as the water is heated instantly and distributed on demand rather than being stored. Combi boilers are the most popular type of boilers in the UK and replacing an older boiler with a new combi boiler will reduce your gas bills significantly.

However, there are downsides to this type of boiler. If you take a shower while someone else is using a tap, less water will reach each point of usage at lower rates of pressure and temperatures as combi boilers can only heat a certain volume of water at any given time.

Is the Baxi Platinum+ 40 combi suitable for my house or flat?

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

The amount of hot water you get from showers, bathrooms, and sinks and heat from your radiators depends on your boiler's output (measured in kilowatts). The higher the level of output, the better your home will be heated and you can be more certain that the water from your taps will be as hot as you want.

However, you must be careful. You might not get the hot water you want if your boiler output is too low. If it's too high, you'll be paying more than you need to for gas.

With the Baxi Platinum+ 40 combi's output at 40 kW, which types of property would this Baxi Platinum+ 40 Combi boiler be most appropriate for?

Most experienced Gas Safe boiler installers would recommend this Baxi Platinum+ 40 Combi boiler as a suitable option for larger properties including detached homes with no more than 15 or more radiators and two or more bathrooms.

You also need to choose a combi boiler with the right flow rate for where you live.

A combi boiler's flow rate is the maximum volume of water (measured in litres per minute) that it can heat and distribute to your radiators, taps and showers at the same time. This Baxi Platinum+ 40 Combi boiler's flow rate is 16 L/m.

However, combi boilers like the Baxi Platinum+ 40 draw water directly from the mains and heat it instantly.

If your mains pressure is 12 litres per minute, your boiler can only heat and distribute hot water at a rate of 12 litres per minute even if it has a higher flow rate.

Combi boilers also struggle when multiple people in your home want to use hot water at the same time - for example, someone running the hot water tap in the kitchen and two people wanting to shower in separate bathrooms.

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 Platinum+ 40 in millimetres

The Baxi Platinum+ 40 has the following dimensions - 700 mm high, 390 mm wide, and 285 mm deep.

Is the Baxi Platinum+ 40 a condensing or non-condensing boiler?

We recommend that you choose a condensing boiler wherever possible like the Baxi Platinum+ 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 Platinum+ 40 combi good for the environment?

With more and more people concerned about climate change, how we heat our homes and the damage it does to the environment is increasingly being questioned by British homeowners.

Dangerous levels of nitrogen dioxide emissions in larger UK cities are caused by gas boilers in domestic properties, and 14% of the UK’s greenhouse gas production is as a result of central heating.

Would installing a Baxi Platinum+ 40 combi boiler in your home be a green choice? 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 Platinum+ 40 was given an efficiency rating of 93% and a band rating of "A".

In 2015, the Energy Related Products Directive (ERP) came into force. The legislation applies to all products that consume energy in production, during their active life, and at the point of final disposal.

The ERP was introduced to incentivise manufacturers to create products that emitted fewer harmful gases with the larger aim of protecting the wider environment.

The Baxi Platinum+ 40 has been awarded an ERP rating of "A" for heat and "A" for water.

What is the length of the warranty on the Baxi Platinum+ 40?

The Baxi Platinum+ 40 boiler is provided with a parts and labour warranty lasting 5 years.
