1. What Is an Air-to-Air Heat Pump and Why should be it?

The growing popularity of renewable energy sources has spurred the nowadays folk to be more eco-conscious, a trend that is reflected by a continuous endorsement of alternative energy technologies for meeting daily household needs. One of the so-called ‘green know-how’ devices that currently enjoys a growing interest from customers (homeowners, ‘green’ advocates, businesses) is the Air source heat pump. This innovative household appliance is gradually becoming the heating system of choice not only for homeowners that are concerned with environmental sustainability but also for those who are looking to get cost-efficient heating as well.

Air source heat pumps can save you thousands of pounds, and tonnes of CO2, and reliably keep your home warm for the next two decades.

Buying a heat pump will cut your carbon footprint by 44%, on average

And they’re on the rise. From April 2022, the government’s Boiler Upgrade Scheme can cut your air source heat pump costs by £5,000 – or give you £6,000 towards a ground source heat pump.

2. Choosing the Right Air Source Heat Pump

If you have a new-build property, just follow the handy table below to get the perfect size of heat pump for your home.

Generally, the bigger the house the bigger the heat pump.

However, these figures must be taken with a pinch of salt. It is not a guaranteed equation, because there are many things that could affect the calculation.

Important questions need to be answered about:

• Insulation, property fabric, and heat loss;
• Size of radiators and/or underfloor heating;
• The number of rooms in the property;
• The types of rooms and their uses, such as Sauna;
• The desired indoor temperature for different rooms;
• Seasonal temperature fluctuations;

The number of different types of rooms is a consideration because some rooms need to be heated more intensively than others; for example, living rooms generally need to be kept warmer than bedrooms, and bathrooms are warmer still. So the number and type of rooms add up to determine the overall heat demand of the house and therefore the size of the heat pump.

If you have poor insulation and/or no underfloor system, you can still use a heat pump to warm your home – it’ll just need to be bigger to make up for these shortfalls.

We will perform a calculation based on the age of the property, its size, the number and size of its rooms and radiators, and whether it has single or double glazing.

Also, check your insulation level and whether you’ve installed underfloor heating pipes.

As noted above, the selection of the right heat pump is a complex and scrupulous process involving a number of calculations that will account for the property’s heating necessities and determine the required air heat pump’s heating capacity to meet these needs on a daily basis. The first step is to determine the rate of the building’s heat losses. This rate can be calculated by using the following formula:

Q = S*(t int. – t ext.)*(1+Σ*β)*n/Rr

where:

“S” is the walls’ surface

“t int.” is the indoor air temperature

“t ext.” is the outdoor air temperature

“β” is the coefficient measuring the impact of the surrounding environment

“n” – additional heat losses

“Rr” – thermal resistance

The resulting data will be used for calculating the property’s total heat losses on the basis of which the annual energy consumption will be established. Next, one should calculate the time it takes for a pump to heat a designated area and the electric power it consumes while doing so. These calculations will help you choose the air-to-air heat pump that is right for your home.

But you don’t just want any extra heating system. You want the best heat pump, the one that will suit your home perfectly, and provide the greatest value for money. We’ve got you covered.
