How to choose a swimming pool heat pump?

JNOD are selling R32 inverter swimming pool heat pump, its heating capacity ranges from 5.5-32Kw. So, it will be a problem for user or wholesaler to choose the suitable heating capacity for different pool sizes. Let us show you 2 methods to choose the suitable.

Simple & General Method

If you do not want to do complicated calculations and do not take into account extreme weather, you can use the following formula: 3KW for 10m³. For example, if you want to heat a 30CBM pool, (30 CBM÷10CBM)* 3KW = 9KW . So, you can choose the 9.5Kw model.

Accurate calculation Method

This method is used to do a very precise calculation on the heating capacity, considering the heating time, water temperature, ambient temperature, etc.

* Step 1: Calculate the needed heating capacity

In the calculation, we usually set the outlet water temperature at 28℃, primary heating time usually is 48hours.

Formula will use: Q=1.163*△t*V ;

W=Q/T

Explanation:    Q = Heat Demand   (KwH)

△t = Temperature Difference (℃)

V = volume of pool （m³）

W = Heat pump capacity(Kw) - usually will add 15-25% of heat loss

T = Hours for heating （H）

Example: A swimming pool 10*4*1.5m, original temperature is 18℃

Answer: set the target temperature into 28℃, heating hour into 48 hours

Q = 1.163*（28-18）*（10*4*1.5）=697.8 KwH

W= (1+15%) *Q/T=1.15*697.8/48=16.72 KW

*Step 2 : Choose the suitable heating capacity depending on working condition

The heating capacity of a heat pump is not constant; it changes with the ambient temperature. Therefore, after calculating the required heating capacity, we also need to choose the model we need according to the ambient temperature.

Still that sample, we calculate that 16.72Kw is needed. If the ambient temperature is around 24-27℃, you can choose the 17.5Kw model; if ambient temp is around 12-15℃, better to choose 25kw model.

Hope this can help you choose suitable models for swimming pool. 

Any question or idea please don’t hesitate to inquire JNOD!

So, what is a heat pump?

A heat pump is part of a home heating and cooling system and is installed outside your home. Like an air conditioner such as central air, it can cool your home, but it’s also capable of providing heat. In cooler months, a heat pump pulls heat from the cold outdoor air and transfers it indoors, and in warmer months, it pulls heat out of indoor air to cool your home. They are powered by electricity and transfer heat using refrigerant to provide comfort all year round. Because they handle both cooling and heating, homeowners may not need to install separate systems to heat their homes. In colder climates, an electric heat strip can be added to the indoor fan coil for additional capabilities. Heat pumps do not burn fossil fuel like furnaces do, making them more environmentally friendly.

Also with water tank inside, it can provide DHW for your kitchen and bathroom.

To achieve heating for our house, there are total three kinds of heat pump we manufacture for our customer. They are:

1. Swimming pool heat pump;

2. Hot water heat pump;

3. Multi function heat pump (heating, cooling & DHW)

WHERE DO HEAT PUMPS WORK BEST?

Homeowners in need of a new heating or cooling system, may consider the type of climate they live in before purchasing a heat pump system. Heat pumps are more common in milder climates, where the temperature does not typically drop below freezing. In colder regions, they can also be combined with EVI system for energy-efficient heating on all but the coldest days.
