Air Source Heat Pump Installation

Overview

Installing an air source heat pump can be a straightforward task if you follow the manufacturer's and our recommendations. This can be done by a competent pool owner, local plumber or pool engineer.

If you cannot find anyone to install this for you, don't panic! Email us info@poolandspacentre.co.uk and we will try to put you in touch with someone who will.

Location

A good fresh air supply is required for the heat pump to work at its best so outdoors is normally best. When choosing your spot, you need to make sure there won't be anything blocking the fans which draw the air in.

If it is a horizontal fan, you don't want anything blocking in front or behind the unit. For example, if the heat pump is situated in front of a wall, it won't have the fresh air supply required. The minimum clearance for horizontal fans is to have at least 2m in front and 300mm behind.

If it is a vertical fan, you don't want anything covering the top or sides, as it will recirculate the same air and it will not perform to its best. They will require plenty of clearance above and at least 600mm at the sides.

You will also need to consider what the heat pump will be fitted onto. It will need to be level and sturdy, whether it is decking, concrete or paving slabs.

In certain humid conditions, some heat pumps will produce condensation so you will need to consider a way of dealing with this if you are mounting on decking or in a specific location. Some units come with a hose connection so you can divert water to elsewhere.

Most of the heat pumps we sell, will not make much noise and give out little vibrations but you can use anti-vibration mounting feet to help cut down on this.

Connecting to your pool plumbing

Your heat pump will require a certain flow rate in order for it to work. Your flow rate will be determined by your pool filter and pump. If you are installing above or below water level, you will need to ensure your pool circulation can cope with this. If you are unsure, please contact us and we will help you.

We sell heat pumps which run on a single and three-phase supply so you will need to check what you have.

Your heat pump should be installed after the filter and normally last before the water is returned to the pool. Unless you have some sort of chlorination system. If installed before this, it could cause problems such as corrosion in the heat exchanger.

Most of our heat pumps come with 50mm inlets and outlets but will work with 1.5-inch pipe. If your existing plumbing is different, we will have the necessary adaptors in stock to work around this.

We advise fitting valves on the inlet/outlet lines and one in between, so you can shut off water flow to the heat pump. We supply these in our shop
