Choosing the Ideal Location
To ensure the optimum performance of your pool heat pump, it is crucial to choose a suitable location with excellent air flow. Here are some guidelines for selecting the right spot for your heat pump:
- Outdoor Installation: The heat pump should be installed outdoors to receive an adequate supply of fresh air.
- Clearances: For horizontal fan heat pumps, allow a minimum of 300mm behind the unit and 2 metres in front. Vertical fan models require at least 600mm clearance around the sides and no obstructions above.
- Avoid Obstacles: Ensure the expelled air will not encounter obstacles like hedges, fences or walls, which could cause recirculation and reduce efficiency.
Understanding Water Flow Rates
The water flow rate through your heat pump is crucial for efficient operation. Check the manufacturer’s specifications for the required flow rate and ensure your pool pump and filter can meet this demand.
- Backwash Regularly: Regularly backwash your pool filter to maintain an adequate water flow rate.
- Water Flow Meters: Use a water flow meter to measure the flow rate through your pipes. These are available in our “Accessories” section.
Preparing a Stable Base
A level and sound base is essential for your heat pump. You can use a concrete base, paving slabs laid on sand, or timber decking. Ensure the base can handle condensation water from the heat pump, as it can produce considerable amounts during operation.
- Mounting Feet and Slabs: We offer mounting feet and lightweight slabs to raise the heat pump off the ground and reduce noise and vibration.
Addressing Electrical Requirements
Before purchasing a pool heat pump, ensure your electrical supply can support the running and startup currents for the unit. Here are some essential electrical considerations:
- Dedicated Breaker: Install a dedicated breaker for the heat pump in your electrical consumer unit.
- Type D Circuit Breaker: Use a type “D” circuit breaker to accommodate the higher current at startup without tripping.
- Armoured Cable: Use armoured cable to prevent accidental damage and run it to a rotary isolator switch within 1 metre of the heat pump.
- RCD Protection: The outdoor electrical circuit should be protected by an RCD.
Efficient Plumbing Setup
To add a heat pump to your existing pool pipework system, follow these steps:
- Determine the size of your existing pipes (common sizes in the UK are 1.5″ or 2″; 50mm is more common in Europe).
- Acquire the appropriate size connectors and elbows.
- If you have an existing pool heater (e.g., gas or oil boiler), leave it in place and connect the heat pump in line with the existing boiler for rapid pool heat-up or to supplement heat in cold weather
Installing a Bypass Valve
A bypass valve can be a valuable addition to your pool heat pump system. Benefits of installing a bypass valve include:
- Allowing water to bypass the heat pump when it is not in use, reducing wear and tear.
- Providing a simple method for isolating the heat pump during maintenance.
- Enabling easy adjustment of the water flow rate through the heat pump for optimal performance.
Final System Check
Before using your newly-installed pool heat pump, double-check the following:
- Ensure all electrical connections are secure and carried out by a qualified electrician.
- Confirm that the plumbing connections are leak-free and secure.
- Test the heat pump’s performance by running it through a complete heating cycle.
By following these guidelines and best practices, you can ensure your swimming pool heat pump installation is successful, efficient, and long-lasting.
