Warmpac and of many other manufacturers and suppliers already use this method as it is essential to choose the right heat pump for the job! Heat need is calculated by measuring three factors:
This approach positions you as an expert and helps you sell more expensive pumps.
With these arguments, customers can be convinced that their basic budgets may not be coherent with their needs or that they should look to amortize a more expensive but more powerful heat pump over time.
The heat pump ventilation system to pick basically depends on the characteristics of the habitat, as Guylene BONTRON-GROS and Bernard PHILIPPE from Warmpac explained.

Although standards exist for pool heat pump performance ratings, they do not include the complete cycle (in particular de-icing) nor variations in weather (wind, seasonality…).
So take account of these factors to boost performance and save on long-term pool heating costs.
Concerning environmental conditions, the FPP estimates that the best performances are reached with an ambient air T° of 15°C, water inlet at 26°C and outflow at 28°C.
If the evaporator is under-dimensioned, the heat pump may have to execute up to three 10 to 15 minutes de-icing cycles every hour. With an evaporator of the correct size, de-icing cycles can be reduced to a few minutes per hour. This means the heat pump will run less to heat the pool water.
Pump noise is an important factor, especially if your client has neighbors likely to complain. Warmpac states that if the difference between the initial temperature and the desired temperature is small, the compressor functions at 20 Hertz, which is equivalent to a whisper or the noise from a refrigerator.
To improve user comfort, it is possible on some models to limit compressor noise. Warmpac also suggests comparing noise levels at 1 m, 5 m and 10 m when choosing a pool heat pump.
Pool heat pump regulations evolve over time and quite soon, French customers will have to plan maintenance and check-up every two years. Anticipate your clients’ fears by proposing a wifi connection to make these checks remotely! You can deliver a certificate proving that the pump is not leaking, which saves time for everyone. Your clients appreciate your foresight and you can intervene at once if a problem occurs and know exactly what material and human resources you have to mobilize.
How to sell pool automation to your customers
Connectivity is now an important decision factor in purchasing and often makes the difference between two similar products. If your customer has connection problems, you can suggest the installation of Carrier Current nodes or a wifi repeater.
We would like to thank Warmpac for sharing its field-experience feedback with everyone in the profession. The pool and spa sector has a host of enthusiastic experts who will meet up at the end of for a new edition of Piscine Global Europe. This ultra-high quality trade show is a “must”!!!

A heat pump is an essential investment for heating your pool. However, choosing the right heat pump can be a challenging task given the wide range of options available. This article offers guidelines and insights to help you make the best choice for your particular situation.
The size of your pool is one of the most important factors when choosing a heat pump. The capacity of a heat pump must match the size of the pool to ensure efficient heating.
If your pool is too large for the heat pump you choose, you will find that the water does not reach the desired temperature or that the pump has to run constantly, leading to unnecessary energy costs.
Therefore, it is essential to make the proper calculations. A general rule of thumb is that you need at least 1 kW of heating capacity per 4m² of pool area.
When choosing the right heat pump, it is also important to consider other factors, such as the location of the pool and the average outdoor temperatures in your area. In areas with colder winters, you may need to choose a more powerful heat pump to ensure the pool remains at a comfortable temperature year-round. In addition, wind and sunshine can also have a significant impact on the pool water temperature, affecting the efficiency of the heat pump.
Furthermore, it is a good idea to consider how often and when you plan to use the pool. If you plan to use the pool frequently, a higher capacity heat pump may be worth the investment because it can heat up faster and keep the water at a constant temperature. This can be especially important for families with children or for people who like to swim in the evenings. So it's not just the size of the pool that matters, but also your usage patterns and the specific conditions of your environment.

When choosing a heat pump, people can often make common mistakes. One common mistake is underestimating the heating capacity required. It is also a mistake to look only at the initial cost without considering long-term operating costs. A cheaper pump may seem attractive in the short run, but it may be more expensive in the long run due to inefficient operation.
It is also important to consider the supplier's warranty and customer service. A good warranty can save you a lot of money in the long run.
Another common mistake is ignoring installation requirements. Heat pumps often require specific conditions for optimal operation, such as adequate space and proper building insulation. Failure to properly assess these factors can lead to suboptimal heat pump performance, resulting in higher energy costs and shorter system life.
In addition, it is essential to consider the type of heat pump that best suits your situation. There are different types of heat pumps, such as air-water, water-water and ground-water systems, each with their own advantages and disadvantages. Making an informed choice based on your specific needs and the characteristics of your home can have a significant impact on the efficiency and effectiveness of your heating system.
When choosing a heat pump for your pool, there are other important factors to consider besides the size of the pool and the type of heat pump.
In addition, it is also essential to consider the installation requirements of the heat pump. Some models require a specific location or additional space for ventilation, which may affect your garden layout. It is advisable to consult a professional installer who can advise you on the best placement and installation of your heat pump so that it can function optimally.
Another factor to consider is the maintenance required to keep the heat pump in good working order. Regular maintenance can help extend the life of the pump and keep it running efficiently. This includes checking the filters, cleaning the condenser and checking the refrigerant levels. By establishing a proper maintenance plan, you can ensure that your investment in a heat pump will pay for itself in the long run.
When selecting a heat pump, you can choose between vertical and horizontal models. The choice may depend on available space and your specific installation requirements.
Vertical heat pumps take up less floor space, which can be an advantage in tight spaces. However, this type of pump often has a more expensive installation because it requires more drilling. In addition, vertical systems are often more energy efficient because they can be placed deeper into the ground, where the temperature is more constant. This can lead to lower energy costs and a faster payback in the long run.
Horizontal heat pumps are often easier to install and can be cheaper, but require more space. It is essential to assess which variant best suits your situation. With horizontal systems, it is important to consider soil conditions and the presence of trees or other obstacles that may affect efficiency. In addition, these systems may be better suited to larger gardens or plots, where there is sufficient space to lay the pipes without sacrificing available garden space.
The heating capacity of a heat pump is expressed in kilowatts (kW) and indicates how much heat the pump can provide. A general guideline is that you need about 1 kW of heat to heat and maintain the temperature of 4 m³ of water. You can calculate the capacity needed by dividing the volume of your pool (in m³) by 4. For example, for a pool with a capacity of 20 m³, you will need a heat pump of at least 5 kW.
The Coefficient of Performance (COP) indicates the efficiency of the heat pump. A higher COP value means a more efficient pump. It is important to note that the COP value varies with the ambient temperature. At lower temperatures, the COP value will be lower. Therefore, it is essential to look at the COP value at the temperature corresponding to your desired swimming season. For example:
Heat pumps are ideal for efficiently heating top-up pools. Thanks to their compact size and energy-efficient operation, you enjoy pleasantly hot water even on cooler days. They are easy to install, consume little power thanks to a high COP value and keep the water at a stable temperature.
