Air Source Heat Pump Installation: Your Comprehensive Guide

As the UK government aims for net-zero carbon emissions by 2050, more homeowners are considering energy-efficient alternatives for heating their homes. One such sustainable solution is the Air Source Heat Pump (ASHP), which uses heat from the outside air to warm your home and hot water.

The installation process of an ASHP, while intricate, can be made simple and seamless with a skilled installer. This blog post will guide you through the key steps and considerations during an ASHP installation.

Pre-Installation Assessment

Before the installation begins, a thorough survey of your home and its surroundings is vital. This step helps determine the right size and type of ASHP for your property. An oversized or undersized pump could lead to inefficiencies and higher running costs, so precise calculations are crucial. At Herts Air Source, we perform an in-depth heat loss calculation to ensure the ASHP is perfectly tailored to your home’s requirements.

Selecting the Right Spot

The outdoor unit of the ASHP needs to be placed in an area where it can easily extract heat from the air. This is usually a spot that is open to the wind and does not collect snow or leaves. The unit should also be installed on a firm base such as a concrete slab to minimise vibration and noise.

Installing the ASHP

After the suitable ASHP system and location have been determined, the installation process can begin. This involves fitting the outdoor unit, indoor cylinder, connecting refrigerant pipes and ensuring all electrical connections are properly made. Herts Air Source experts ensure a smooth and efficient installation process, adhering to all MCS installation standards.

Additional Features

Depending on your specific needs, you might opt for additional features, such as underfloor heating, which can work very effectively with an ASHP due to its low operating temperatures.

System Setup and User Education

Setting up the ASHP system correctly is vital to ensure it operates efficiently. After the installation, at Herts Air Source, we take the time to educate you on how to use your new heating system. It’s crucial to understand the change from a traditional gas boiler to an ASHP; it works best at lower temperatures and is most efficient when left on continuously.

Aftercare and Follow-ups

After the installation, it’s essential to keep the system maintained for optimal performance. We provide a 12-month support package to ensure your system continues to run efficiently and offer a free 6-month review, during which we visit your property to check the system.


Switching to an ASHP is a decision that has significant benefits both environmentally and financially. However, correct installation is key to realising these benefits. At Herts Air Source, we are committed to providing top-notch installation services, keeping the process transparent and ensuring that your ASHP system delivers maximum efficiency. With a dedicated team of skilled installers and a customer-centric approach, we aim to make the switch to an ASHP seamless and beneficial for you.
