Is the Potterton Promax Ultra 24kW a standard, combi or system boiler?

You may wish to consider installing the Potterton Promax Ultra 24kW if you are looking for a heat only boiler for your house or flat.

If your home has more than one bathroom or you have a large family that uses a lot of hot water, a heat only boiler (sometimes called a regular boiler, a conventional boiler or a standard boiler) is likely to be the best option for you. Heat only boilers require both a hot water or immersion cylinder and a cold water tank. Once the water in the cylinder is heated, you can use this hot water throughout the day and it can feed multiple taps and showers at the same time.

This is in contrast to a combi boiler which can only heat a limited amount of water at any one time. This can cause a problem if two or more taps and showers are being used simultaneously as the temperature, pressure and volume to all points will drop.

Heat only boilers allow you to program the times that you wish heat and hot water to be available. However, if you forget to do this and the immersion cylinder is empty, you may have to wait up to an hour before hot water becomes available again.

If your property already has a water tank and cylinder, it will nearly always be cheaper to replace like for like and not choose a different type of boiler. In addition to new pipework, you may need to replace older radiators that may be unable to cope with the higher water pressure delivered by other types of boiler.

Is the Potterton Promax Ultra 24kW heat only boiler suitable for my house or apartment?

Whether this Potterton Promax Ultra 24kW heat only 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 Potterton Promax Ultra 24kW heat only boiler is 24 kW, so which types of property would this be appropriate for?

Most experienced Gas Safe boiler installers would suggest that the Potterton Promax Ultra 24kW heat only boiler would be a suitable choice for installation in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

What is the size of the Potterton Promax Ultra 24kW?

The size of the Potterton Promax Ultra 24kW boiler is 625 mm tall, 370 mm wide, and 270 mm deep.

Is the Potterton Promax Ultra 24kW condensing or non-condensing?

The Potterton Promax Ultra 24kW is a condensing gas boiler - this is the type of boiler we recommend to most clients because they're better for the environment and they will save money on annual fuel bills.

A condensing boiler captures and recycles the warmth still present in both the flue exhaust gases and water vapour condensation created when gas is burned to provide your boiler with power.

This means it needs less gas to operate and it uses this extra energy to perform a number of tasks, including heating the colder water that comes back to the boiler from the radiators in your home.

Is the Potterton Promax Ultra 24kW heat only an energy-efficient boiler?

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.

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 Potterton Promax Ultra 24kW heat only help the environment? Let’s see what the performance figures suggest.

Every boiler manufactured and supplied in the UK must have an energy efficiency rating of 92% (SEDBUK “A” rating). These minimums were made law in April 2018 - before that, the minimum energy efficiency rating was 88% (88%/89% = "B" SEDBUK grade, 90%+ = "A" SEDBUK grade).

The Potterton Promax Ultra 24kW was awarded an efficiency rating of 89.1% and a band rating of "A".

Energy efficiency ratings for boilers describe the amount of energy they use and waste when switched on and working.

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 emit fewer harmful gases with the larger aim of protecting the wider environment.

The Potterton Promax Ultra 24kW has been awarded an ERP rating of "A".

Is there a warranty on the Potterton Promax Ultra 24kW heat only boiler if it breaks down?

The Potterton Promax Ultra 24kW boiler is covered by a parts and labour warranty of 2 years.
