Looking for something a little cheaper? There are plenty of other combi boilers available in their range, such as the Baxi 600.

For smaller properties, there’s the Baxi 624. And for those with average hot water and central heating demand, you’ll be looking towards the more powerful Baxi 630. Better still, the 600 is a compact boiler with a long warranty; we’ve written a quick guide to the Baxi 600 compact here.

Baxi Platinum Combi Reviews

Online reviews are always an interesting read. Although there aren’t a tonne of reviews on Baxi’s Platinum combi boilers, there are some.

One place worth mentioning is Reevoo; here, you can find separate reviews for several combi boilers from this range (although there doesn’t seem to be a Baxi Platinum 33 review). Based on all the reviews, however, the range has average score of 9.2/10 at time of writing.

Baxi Platinum Combi Boiler Size

There’s one big question we often get: will Baxi’s Platinum combi boiler fit in a kitchen cupboard? And, the answer is no.

Baxi designed the Platinum combi range with heat output, not size, in mind. The dimensions mean it’s just slightly too big for a kitchen cupboard. As we’ve mentioned above, if you want a 24kW/30kW Baxi compact boiler, you should consider the Baxi 624 and 630 models instead.

Baxi Platinum Flow Rate

Baxi have made sure the Platinum range really stands out. Not only are they excellent value for money, they are extremely powerful. The larger Baxi Platinum+ 40kW combi boilers have a 0.5L higher flow rate than the equivlent Worcester.

Model Heat Output Hot Water Output Hot WaterFlow Rate
Platinum 24HE 24kW 24kW 9.8 L/minute
Platinum 28HE 24kW 28kW 11.5 L/minute
Platinum 33HE 28kW 33kW 13.5 L/minute
Platinum 40HE 32kW 40kW 16.4 L/minute

Baxi Platinum Warranty

As we’ve already mentioned, this range comes with an impressive 10-year parts and labour warranty. The terms and conditions of the warranty can be found here.

We mention this in most of our boiler reviews — avoid cheap boilers with a 2-year warranty. At the end of the day, if a boiler manufacturer anticipates boiler repairs being needed after 2 years, that’s the warranty they’ll give. And after spending thousands on boiler installation, the last thing you want is to be forking out for repairs just 24 months down the line.

Typically, we’d advise heading for a boiler that has a warranty in excess of 5 years. And in that respect, Baxi’s warranty blows the majority of other boilers out of the water.

Remember, like most boiler manufacturers, Baxi stipulate that the boiler must be serviced annually by a Gas Safe engineer for the warranty to remain effective.

Suitable Property Size

The table below gives you an idea of which Platinum combi boiler size your property will need.

Model Property
Platinum 24 kW Combi Smaller properties with 5-6 radiators and 1 bathroom
Platinum 28 kW Combi Small properties with 5-8 radiators and 1 bathroom
Platinum 33 kW Combi Mid-range properties with 3-4 bedrooms and up to 10 radiators
Platinum 40 kW Combi Large properties with up to 15 radiators and the ability to power 2 showers at once

It’s worth noting that this table is simply a guideline. Different properties have different central heating and hot water demands.

Also, note that if your household has exceptional hot water flow rate demands, you should consider a different boiler type altogether. A combination boiler supplies hot water on-demand, relying on the mains water pressure; this means it won’t suffice if you’ve got several taps and the central heating system all running at once. If this sounds like your situation, then you should consider a system boiler instead.

You can use this clickable form to determine which boiler you need for your property.

ErP Space Heating Efficiency Rating

Like most new boilers from leading brands, the Platinum combi is incredibly efficient, with an ErP A-rating for energy efficiency (90% efficiency).

And that’s important. New rules related to Boiler Plus mean that boilers need to be this efficient (this doesn’t retroactively apply to old boilers).

Given it’s high efficiency, it’s not just compliant with Boiler Plus, it’s also endorsed by the Energy Saving Trust.

What kind of fuel does your boiler use?

Installation Flexibility

Baxi’s Platinum range comes equipped with frost thermostat, which gives you the flexibility to install the boiler in an environment where you’d expect the temperatures to be quite low. We’re talking about garages, lofts, and other parts of your home where the temps can plummet below zero and freeze the water inside the boiler’s brass hydraulics — something you want to avoid if you want the boiler to last long.

Before you decide where to install your boiler, however, make sure that you have sufficient side clearance. For Baxi’s Platinum range combi boilers, the clearances are as follows:

  • Side clearance = 5mm
  • Upper clearance = 200mm
  • Lower clearance = 150mm
  • Front clearance = 5mm in operation, 450mm for service

Baxi Platinum Alternatives

Naturally, Worcester have a full line-up of boilers that rival the Platinum combi range.

As a quick guide, the Worcester Bosch Greenstar 400 25kW would be a suitable alternative to the Baxi 24 kW Platinum, whilst the Greenstar 4000 30kW Worcester’s equivalent of the 28 kW Platinum. You can get online prices for both via Heatable.

Worcester Bosch Greenstar 4000

Another option to consider is the Ideal Vogue, which we’ve covered in detail here. This is really a matter of personal preference, as they both have 10-year warranties and a similar price point. For instance, the Ideal C40 Vogue and Baxi’s Platinum 40kW are both around the £1,200 mark (boiler only).

If you’re looking for a cheaper alternative, still with a good warranty, it’s worth considering the Baxi Duo Tec and Ideal Logic Plus. Both boilers weigh in with a decent warranty of 7 years. More importantly, they are over £250 cheaper at most plumbing merchants.

Baxi Platinum Review Verdict

As far as boilers with a 10-year warranty go, the Baxi Platinum offers a well-designed, affordable option. These boilers have reliable components, an outstanding energy efficiency rating, and a user-friendly control system. The long warranty is a testament to Baxi’s quality, and the reasonable price point is certainly appealing.
