Safety Requirements and Product Limitation Considerations
- Warning: If the installation of the unit requires new high-amperage electrical outlets, all electrical work must be performed by a licensed electrician.
- Consider the cold air evacuation path the unit will have. A pool heat pump must be installed in such a way that the cold air flow is unobstructed and preferably directed out of a backyard, if the backyard is fully enclosed with a fence, for maximum running efficiency.
- On the air inlet side, the heat pump doesn't need as much clearance, but you should consult the manufacturer’s installation guide for specific clearance measurements to avoid overheating or reduced efficiency.
- Be aware that pool heat pumps generate noise while operating (see table specifications above). Consider placing the unit in an area where noise will not be disruptive, especially if located near living spaces or neighbors.
- Regular scheduled maintenance, such as cleaning the evaporator coil, is essential for optimal performance. Refer to the manufacturer’s installation guide for the recommended service schedule by a qualified technician.
- If you live in a region with freezing temperatures, be sure to winterize the heat pump according to the manufacturer’s recommendations to prevent damage to internal components.
- Consider the energy consumption of a pool heat pump. Please be aware of the running costs, you can use our industry-leading heat load calculators to get an estimate of annual running costs.
Frequently Asked Questions (FAQs)
Q. What size heat pump should I get?
A. This depends on several factors, including the size of your pool, a number of the pool's heat
loading factors, including location, the use of a transparent pool cover, your desired water temperature, and when during the year you expect
to bring the pool up to temperature from a cold start. Try our heat pump sizing calculator. It will accurately tell you what size heat pump you need
for your specific pool heat loading as well as heat-up times, and whether a particular heat pump will be able to heat a pool to a specified
temperature. It will also give you an excellent indication of heating costs.
Q. Can I install an electric heat pump myself?
A. It is recommended to have a professional install the heat pump, especially if any electrical work is
required. However, for the plumbing side, installations are not too difficult if you're handy and the instructions provided by the manufacturer
are clear. The most common mistake in heat pump installations is failing to provide a clear path for the spent cold, dry air to be ejected away
from the backyard and pool area.
Q. What’s the coldest temperature a heat pump will continue to work at?
A. This depends on the manufacturer and the specific heat pump, but on average, heat pumps can operate in
temperatures as low as 0°C and as high as 40°C.
Q. What is a heat pump's COP?
A. The Coefficient of Performance (COP) measures the efficiency of the heat pump. It is defined as the ratio
of the heat energy output to the electrical energy input. For example, a COP of 5 means that for every 1kW unit of energy consumed, the heat pump
produces 5kW units of thermal heat. COP factors are not the best indicators of heat costs, as manufacturers will typically tout peak COP factors in
favorable conditions. You really should use a de-rated SCOP (Seasonal Coefficient of Performance), as this takes into consideration the average COP
factor the heat pump will run at across the season, as well as de-rating factors for poor airflow (if any), unit aging effects over its life, and air
fin cleanliness, all of which will decrease the SCOP factor.
Q. I use salt in my pool rather than chlorine. Will this damage the heat pump?
A. Most modern heat pumps are designed to handle saltwater pools. However, it is important to check with the
manufacturer to ensure that your specific model is compatible with saltwater.
Q. Should I cover the heat pump in winter?
A. Yes, a winter cover protects your heat pump from the elements and extends its lifespan. Use a cover designed
for your model to ensure proper ventilation and protection.
Q. Can I install a heat pump in my pool plant room?
A. It is generally not recommended to install a heat pump in an enclosed space like a pool plant room because it
needs adequate airflow to operate efficiently. However, if you can provide an outlet from the plant room through which the heat pump can eject the air
unimpeded into an area that clears it from the pool and the plant room's entrance, then yes, you can install the heat pump in a plant room.
Q. How are the units delivered?
A. Heat pump units are typically delivered by freight carriers on a wooden pallet. Note, they are very heavy,
approximately 40-80kg depending on the size of the unit. The delivery driver will have a pallet jack to unload the unit using a tailgate truck. You will
need two people to move the unit around. The units are packaged securely to prevent damage during transport, but it's important to inspect the unit upon
arrival for any visible damage and take pictures for proof of damage.
Q. Do I still need a pool cover if I have a heat pump?
A. Yes, using a pool cover can significantly reduce heat losses and dramatically lower the running costs of your
heat pump by retaining the heat in your pool overnight. If you dislike pool covers, consider using one overnight and/or at the start and end of the pool
season, as heating costs without one in the peak of summer are not that high.
Q. Can I combine solar with a heat pump?
A. Yes, combining solar heating with a heat pump can be an efficient way to heat your pool. Using solar to provide
heat during sunny days and the heat pump to top up the temperature in the afternoon if solar heating was insufficient is ideal, as heat pumps would then
get the benefit of warmer afternoon air temperatures. Solar pool heating systems typically harvest most of their energy by about 3pm, so running a heat
pump after that is ideal.
Q. What kind of maintenance is required?
A. Regular maintenance includes cleaning the heat pump's main heat exchange fins and any filters, checking for
debris around the unit, performing any self-diagnostics, and having a professional inspect and service the unit annually to ensure it is operating efficiently.
Q. What size pipe outlets are on the units?
A. Pipe outlet sizes can vary depending on the model and manufacturer. Typically, they range from 40PVC to 50PVC.
Check your heat pump’s specifications for the exact size.
Q. How fast can the pool be heated by the heat pump?
A. This depends on several factors, including the size of your pool, a number of the pool's heat loading factors,
including location, the use of a transparent pool cover, your desired water temperature, when during the year you expect to bring the pool up to temperature,
and its starting temperature. Try our heat pump sizing calculator.
It will accurately tell you if a particular heat pump will be able to heat a pool to a specified temperature and the time it will take to do so for your specific pool heat loading factors.
Q. How loud is the pump?
A. Noise levels vary by model, but most modern heat pumps are designed to operate quietly, typically around 50-60
decibels, similar to the noise level of a conversation at home.
Q. What are “Inverter Driven” heat pumps?
A. Inverter-driven heat pumps use variable-speed technology to adjust the compressor's speed, providing more precise
temperature control and higher energy efficiency compared to traditional on/off heat pumps.
Q. Should I oversize my heat pump for better COP efficiency?
A. Oversizing your heat pump can improve COP efficiency because the unit won't have to work as hard to maintain the
desired temperature. However, it's important to balance efficiency with cost and avoid significantly oversizing if you don't plan on swimming during adverse
weather conditions.
Q. What kind of electrical socket specification do I need?
A. This depends on the size of the heat pump. It is recommended to leave this aspect to a qualified electrician to
ensure correct and safe installation.
Q. Do you ship to any location?
A. No, we only ship to locations that can be serviced by the supplying manufacturer. The listing will indicate which
locations a particular heat pump can be shipped to.
Q. How much does it cost to heat a swimming pool?
A. This depends on several factors, including the size of your pool, a number of the pool's heat loading factors,
including location, the use of a transparent pool cover, your desired water temperature, and when during the year you want to be swimming. Try our
heat pump sizing calculator.
It will give accurate running costs for any particular scenario.
Q. Can I plumb my heat pump into an independent line, or do I plumb it into the main filter line?
A. It is generally recommended to plumb the heat pump into the main filter line to ensure proper water circulation and filtration.
Q. How does a heat pump compare to other pool heating options like gas heaters or solar panels?
A. Heat pumps are generally more energy-efficient and cost-effective compared to gas heaters, though gas heaters can
heat the pool more quickly. Solar panels are the most environmentally friendly and cost-effective solution in the long run, but they are dependent on sunny
weather and may not be sufficient on their own in cooler climates. They also require a decent roof space.
Q. What is the expected lifespan of a heat pump?
A. With proper maintenance, a heat pump can last between 10 to 20 years. Regular servicing and following the
manufacturer's guidelines can help maximize the lifespan of the unit.
Q. Are heat pumps environmentally friendly?
A. Yes, heat pumps are considered environmentally friendly compared to gas heaters, but this strongly depends on the
source of your electricity, i.e., whether or not it's produced by burning fossil fuels. The most environmentally friendly option is, of course, solar.
Q. Can a heat pump be used for both heating and cooling the pool?
A. Yes, some heat pump models offer both heating and cooling functions, allowing you to maintain a comfortable pool
temperature year-round.
Q. How long does it take to install a pool heat pump?
A. Installation time can vary based on the complexity of the setup, but typically it takes between 1 to 2 days.
This includes installing the foundation (if required), setting up the unit, connecting the plumbing and electricity, and testing the installation.
