Baxi Platinum 40 Combi Gas boiler frequently asked questions

Which category of boiler does the Baxi Platinum 40 fit into?

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

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 Platinum 40 combi boiler appropriate for my house or apartment?

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?

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

With combi boilers, you need to consider the flow rate as well as the output rate. The flow rate (shown in litres per minute) measures how much water your boiler can draw from the mains which it then instantly heats and distributes to your taps and radiators.

However, a high flow rate is of little to no value if your local water pressure is low. If your local mains water pressure is 10l/m and your flow rate is 12l/m, your boiler will only be able to process 10l/m.

If you live in an area with high water pressure but your household has multiple bathrooms and/or radiators and many members of your household want to use hot water at the same time (like morning or evening baths or showers), it's unlikely that you'll be able to find a combi with a high enough flow rate.

As an indication, a power shower needs about 10 litres of water per minute, whereas the flow rate of this Baxi Platinum 40 Combi boiler is 16 L/ml/m.

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.


How large is a Baxi Platinum 40 boiler?

The Baxi Platinum 40 is 780 mm [H] by 450 mm [W] by 345 mm [D] in size.

Is the Baxi Platinum 40 condensing or non-condensing?

Condensing boilers like the Baxi Platinum 40 improve energy efficiency and reduce your annual expenditure on gas.

They do this by capturing and recycling the warmth still present in water vapour condensation and flue exhaust gases to, for example, increase the temperature of the colder water returning from your radiators.

Condensing boilers are also much better for the environment because they emit fewer greenhouse gases.

Is the Baxi Platinum 40 combi rated as environmentally friendly?

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.

As much as 14% of the UK’s greenhouse gas production derives from our domestic central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in Britain's largest cities.

Would choosing a Baxi Platinum 40 combi help the environment? Let’s see what the performance figures suggest.

An energy efficiency rating of 92% or above is a legal requirement for all boilers manufactured and installed in the UK today. 92% is equivalent to a low-to-middle "A" grade on the "Seasonal Efficiency of Domestic Boilers" (SEDBUK) scale.

Energy efficiency measures how much energy a boiler uses and wastes in the course of its normal operation. The lower the waste, the lower your gas bills.

The Baxi Platinum 40 was awarded an efficiency rating of "92%", equivalent to a "A" rating on the SEDBUK system.

The Energy Related Products Directive (ERP) intends to reduce the amount of energy consumed by individual products over their entire lifetime, from the initial manufacturing process to final disposal and at all points in between.

The legislation is designed to encourage manufacturers to create products that are more environmentally friendly and which result in a reduction in harmful gas emissions.

The ERP rating for the Baxi Platinum 40 is "A" for heat and "A" for hot water production.

How long am I covered by the warranty for if the Baxi Platinum 40 breaks down?

The parts and labour warranty on the Baxi Platinum 40 lasts for 10 years.

Baxi Platinum 40 Combi Gas boiler frequently asked questions

Baxi Platinum 40 - a regular, combi or system boiler?

The Baxi Platinum 40 boiler is an option you may wish to consider if you're looking for a combi boiler for your house or flat.

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 a suitable option for my house or flat?

Whether this Baxi Platinum 40 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.

A boiler’s output is a measurement of the amount of power it can use to provide hot water to your taps and radiators. The higher its output rate, the more water it can heat.

If your new boiler’s output is too low, your hot water might not be as hot as you want it to be. If it's too high, you’ll be paying more for gas than you need to.

The output of the Baxi Platinum 40 combi boiler is 40 kW, so which types of property would this be 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.

With combi boilers, flow rates are as important a consideration as output rates.

All combi boilers draw water from the mains. They then heat this water instantly whenever it's needed and distribute it to your radiators and taps.

A boiler's "flow rate" describes how much water a boiler can draw from the mains at any one time, which it then heats and sends around your home (measured in litres per minute). This Baxi Platinum 40 Combi boiler's flow rate is 16 L/m.

If your home has a large number of radiators, a lot of bathrooms, or multiple people who wish to use the hot water at the same time, your combi boiler may not be able to draw as much water from the mains as it needs to serve everyone, regardless of how high the flow rate is.

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.


How big is the Baxi Platinum 40?

The size of the Baxi Platinum 40 boiler is 780 mm tall, 450 mm wide, and 345 mm deep.

Is the Baxi Platinum 40 condensing or non-condensing?

We always recommend to clients that they select the very latest condensing boiler for their home.

Condensing boilers like the Baxi Platinum 40 are more efficient with the gas they use in operation, meaning that you'll benefit from lower fuel bills. Condensing boilers are also better for the environment.

They achieve their efficiency by capturing and recycling the heat still present in the water vapour condensation and flue exhaust gases created when a boiler burns gas to get the energy it needs. It then reuses that recycled heat to perform a number of tasks, including heating the colder water that comes back to your boiler via the radiator.

Is choosing the Baxi Platinum 40 combi boiler environmentally friendly?

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about 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 the environmental impact of installing a Baxi Platinum 40 combi in your home be positive? Let's look at the numbers.

All boilers manufactured after April 2018 in the UK must be rated as an “A” on the SEDBUK grading system, subject to a minimum energy efficiency rating of 92% or above. Before that, the minimum rate was 88% - boilers with an energy efficiency of 88% or 89% were given a “B” rating. Boilers scoring 90% or more were given an "A" rating.

The energy efficiency rating for a boiler describes the amount of energy it uses and how much goes to waste in operation.

The Baxi Platinum 40 has an efficiency rating of 92% with a SEDBUK grade of "A".

The Energy Related Products Directive intends to encourage all manufacturers to reduce the harmful gas emissions associated with the products they make, from the manufacturing stage to final disposal, including when they are in active use.

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

How long am I covered by the warranty for if the Baxi Platinum 40 breaks down?

The Baxi Platinum 40 boiler has a warranty covering parts and labour costs for up to 10 years after installation.
