Let Hoval help take the stress out of choosing your heat pump, by knowing what to expect, and what you want from it beforehand.

Many architects and designers are keen to install heating solutions that don’t stand in the way of sustainability. And that’s why we are seeing more and more buildings having their heating and hot water provided by heat pumps. However, choosing which type of heat pump to rely on is no mean feat. There are so many different criteria to factor in to ensure that you end up with the perfect solution – design, integration, and spacing requirements are just a few on an extremely extensive list. But if you consider all of the points below, you will be sure to find just what you need for your project in no time.

Space required – which heat pump will fit?

The top choice of heat pump for your home is ultimately going to come down to the space available in the building. Nowadays, particularly in London, we are seeing more and more buildings with extremely small amounts of space to install pumps and/or plant rooms, luckily, Hoval offer a wide range of tailor made solutions... so you're sure to find your perfect fit.


A geothermal heat pump with an output of 7 kW requires a flat surface of around 300 m2. In this case, energy is extracted by surface collectors.

The way energy is extracted by geothermal heat pumps with deep boreholes means that this solution saves on space, but you are faced with higher costs and more building work as a result.

Roughly the same amount of space is required for water heat pumps, which require wells to be created. There are plenty of specific rules and regulations to follow here. For example, you will have to consider the distance between neighbouring wells and the depth of your own well. If you want to go down this route, you will need to get in touch with the local authorities for further information.

Air source heat pumps have an outdoor unit, which means they take up less space. The fact that they are also easy to integrate makes them an ideal choice for renovation projects.

Noise – how loud should my air source heat pump be?

If you are leaning towards an air source heat pump, you’ll have to give some thought to the noise element.

The noise produced by a piece of technical equipment should not exceed an acceptable level, which varies from location to location, and building to building, with some areas requiring a very low level of noise. This is something to consider when choosing your heat pump, as they all make varying amounts of noise. Your local Hoval Area Sales Manager can help you with this.
