Baxi Platinum 28 Combi Gas boiler frequently asked questions

Is the Baxi Platinum 28 a combi, system or regular boiler?

Looking for a gas combi boiler for your house or flat? If you are, the Baxi Platinum 28 boiler may be worth considering.

Combi boilers provide hot water or heating for your home on demand. You just need to turn the tap to get hot water or switch on the radiator and you’ll feel your home warm up within minutes.

In contrast, traditional boilers required either one or two large storage tanks to work - one to heat and keep water warm and the other to hold cold water for later heating. If the immersion tank was empty, it wasn’t uncommon to wait up to an hour for enough hot water to fill a bath, for example.

Combi boilers draw cold water from the mains and then heat it instantly whenever it's needed, all from one small unit.

The one disadvantage to combi boilers is that, if more than one point is in use at any one time (for example, if someone is taking a shower and another person turns on a hot water tap elsewhere in the property), water pressure, temperature and volume drop to both points.

Should I choose a Baxi Platinum 28 combi boiler for my house or flat?

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 Platinum 28 combi's output level is 28 kW, so which types of property would this Baxi Platinum 28 Combi boiler be an appropriate choice for?

To most boiler engineers, the Baxi Platinum 28 combi Platinum would be most suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

Please remember to consider "flow rates" as well when choosing your new boiler. All combi boilers including the Baxi Platinum 28 draw water from the mains.

Each combi boiler has its own flow rate (measured in litres per minute) - this tells you how much water it can heat and distribute to your home’s taps and radiators straight from the mains. This Baxi Platinum 28 Combi boiler's flow rate is 12 L/m.

There is no benefit to you in choosing a combi with a high flow rate if your mains pressure is low - save money by buying a boiler whose flow rate is equal to or slightly more than the pressure in your water pipes.

In addition, if you have a lot of radiators and bathrooms in your home or you have a large household that often uses lots of hot water at the same time, like for regular morning and evening showers, a combi boiler may not be suitable.

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 size is a Baxi Platinum 28 boiler?

The Baxi Platinum 28 boiler is 780 mm high, 450 mm wide, and 345 mm deep.

Is the Baxi Platinum 28 a non-condensing or condensing boiler?

Condensing gas boilers like the Baxi Platinum 28 are environmentally friendlier and cheaper to run so, if possible, we strongly recommend that you choose this or one of the very latest models.

Condensing boilers are much more efficient and economical to run because they contain a secondary heat exchanger that captures and recycles the warmth still present in the flue exhaust gases and the water vapour condensation for re-use, meaning that they use less gas to run.

How does the Baxi Platinum 28 combi boiler rate environmentally?

With growing concern among the public about accelerating climate change, how we heat our homes and the impact this has on the environment has become a major topic of concern for many homeowners.

In the UK, central heating is responsible for 14% of greenhouse gas production. Domestic gas boilers emit large quantities of nitrogen dioxide in British cities.

Would choosing a Baxi Platinum 28 combi help the environment? Let’s see what the performance figures suggest.

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 Platinum 28 was given an efficiency rating of 92% and a SEDBUK grading of "A".

The Energy Related Products (ERP) Directive is a European directive which applies to all products that consume energy over their lifetime.

It encourages companies to create products that are environmentally friendlier at all life cycle stages, including initial manufacturing and end use through to final disposal, with the aim of reducing harmful gas emissions.

The Baxi Platinum 28 is rated "A" for heat and "A" for water.

What warranty does the Baxi Platinum 28 combi boiler come with?

The Baxi Platinum 28 boiler offers a parts and labour warranty of 10 years.

Baxi Platinum 28 Combi Gas boiler frequently asked questions

Is the Baxi Platinum 28 boiler a combi, regular or a system boiler?

The Baxi Platinum 28 boiler is a combi boiler you may wish to consider when looking for a new boiler for your house or flat.

In the past, most boilers needed one or more storage tanks to operate - one to store warm water and the other for storing water to be heated later. But storage tanks are problematic in properties where space is at a premium and particularly where there is no loft. Many properties in the UK are small and so manufacturers introduced combi boilers in the 1970s to eliminate the need for tanks.

With a combi boiler, the hot water for your radiators and taps is delivered on demand. The boiler instantly heats water it draws directly from the mains internally. It then distributes the heated water around your home at mains pressure as you need it.

It is important to bear in mind that, while combi boilers have many benefits, they can only heat a certain volume of water at any given time. This means that, if you run a shower at the same time as someone else is doing the washing up in the kitchen, the volume of water passing to each point will drop, causing a fall in pressure.

Is a Baxi Platinum 28 combi the right boiler for my house or flat?

Whether this Baxi Platinum 28 Combi boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions, however - it means how powerful it is.

Measured in kilowatts, a boiler's output level is an indication of the amount of power it has available to it to heat the water coming from your taps and for warming your radiators. The greater the output level, the more water it can heat.

If you choose a boiler whose output level is too low, you'll often find that the water is not as hot as you want it to be. If you choose a boiler whose level is too high, you'll be paying higher gas bills than you need to for years to come.

The output of the Baxi Platinum 28 combi is 28 kW, so which types of property is this Baxi Platinum 28 Combi boiler appropriate for?

An experienced boiler engineer would recommend that this Baxi Platinum 28 Combi boiler would provide adequate heating and hot water for medium-sized homes and larger apartments with up to 10-15 radiators and two 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 28 Combi boiler is 12 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 big is the Baxi Platinum 28?

The dimensions of the Baxi Platinum 28 are 780 mm [H] x 450 mm [W] x 345 mm [D].

Is the Baxi Platinum 28 a non-condensing or condensing boiler?

We strongly recommend that you choose a condensing boiler like the Baxi Platinum 28 - the technology is improving every year so the newer the boiler, the better.

A condensing boiler captures and recycles the warmth still present in flue exhaust gases and water vapour condensation into heat, allowing it to perform more efficiently on tasks like heating the colder water returning from your radiators.

They also offer significant annual savings on household gas bills as well as being more environmentally friendly.

How environmentally friendly is the Baxi Platinum 28 combi?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important environmental issues.

Nitrogen dioxide emissions in Britain's largest cities are at dangerous levels and this has been caused by gas boilers. In fact, 14% of the UK’s greenhouse gases are produced by central heating.

Would the environmental impact of installing a Baxi Platinum 28 combi in your home be positive? Let's look at the numbers.

Boilers manufactured or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to this, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The Baxi Platinum 28 has been given a rating of 92% for energy efficiency, equivalent to a SEDBUK "A" rating.

The Energy Related Products Directive grades products according to the energy they consume and the harmful gas emissions they create, from manufacturing right through to final disposal, including how they're used by customers between these two points.

The Baxi Platinum 28 is rated "A" for heat and "A" for water.

Does a Baxi Platinum 28 combi boiler come with a warranty period?

A parts and labour warranty of 10 years is included with the Baxi Baxi Platinum 28 boiler.
