Heat Pump or Solar Panel Pool Heating

Heat Pump Pool Heating Explained

---

1. What is a heat pump?

A heat pump is a highly efficient heating system that works much like an air-conditioner in reverse. It extracts heat energy from the surrounding air and transfers it into your pool water, increasing the water temperature and extending your swimming season.

---

2. How does a heat pump work?

The unit absorbs heat from the outdoor air and transfers it through a heat exchanger. Pool water is circulated through the heat pump, warmed, and returned to the swimming pool. A built-in thermostat automatically maintains your chosen temperature.

---

3. What size heat pump do I need?

The correct size depends on:

• Pool surface area

• Pool water volume

• Desired water temperature

• Ambient climate conditions

We assess your pool and recommend the right unit to ensure fast, efficient heating.

---

4. Where is the heat pump installed?

Heat pumps are installed outdoors near your pool pump and filtration system. They do not require covering and should not be enclosed — proper airflow is essential for performance.

---

5. How complex is installation?

Installation is straightforward. Requirements include:

• A dedicated 220-volt electrical circuit

• Connection to your existing pool pump system

• Adequate space for airflow

• A level surface (existing concrete slab or new one if needed)

If your pool uses a chlorinator, it must be placed downstream with a check valve to prevent chemical damage.

---

6. What are the running costs?

Heat pumps are one of the most economical pool-heating options, using:

• Free heat from the air, and

• Low electrical consumption to run the compressor

Solar heating is the only lower-cost option — but it heats only when sunlight is available.

---

7. Is maintenance required?

Maintenance is minimal. Simply:

• Keep the unit free of leaves/debris

• Maintain balanced pool water chemistry

• If near the coast, rinse the evaporator coils occasionally to prevent salt build-up

---

8. Can a heat pump heat the pool overnight?

Yes — depending on pool size and outdoor temperature. Once your pool reaches your desired temperature, the heat pump will maintain it consistently throughout the season.

---

9. What are kW and BTU?

• kW = kilowatt, a measure of electrical power

• BTU = British Thermal Unit, a measure of heating output
  (1 kW = 3,412 BTU)

---

10. What does COP mean?

COP (Coefficient of Performance) indicates energy efficiency — the ratio of heat output to electricity consumed. A higher COP means lower running costs and better efficiency.

---

11. Why use a solar blanket/pool cover?

A pool cover significantly reduces heat loss and evaporation — the biggest cause of heat loss. A quality cover can reduce heat loss by 50% to 95%, helping maintain temperature and reduce energy costs.

---

12. Will the heat pump run continuously?

No. Once you set the desired temperature, the thermostat monitors the water temperature and activates the unit only when needed.

---

13. How is the heat pump controlled?

Through a programmable digital control panel with a thermostat and temperature display.

---

14. Minimum operating temperature

AQUA-HEAT heat pumps feature a de-ice system and can continue heating efficiently at temperatures near 0°C, suitable for winter conditions.

---

15. Will the heat pump ever need more refrigerant?

The refrigeration system is factory-sealed. The refrigerant (Freon) should last for the life of the unit. Only in rare cases, such as physical damage causing a leak, would a recharge be required.
