The Sun Spring 07 is a powerful plug and play heat pump for smaller pools and is compatible with all market leading brands. (Bestway, Intex etc)
The environmentally friendly and energy saving air source heat pump produces a slow temperature rise of 1 to 3° C per 24 hours.
When the heat pump is started for the first time, it must be operated continuously until the desired temperature (set temperature) is reached. In this case, the filter pump must operate 24 hours a day.

The temperature rise time of a heat pump depends on a number of parameters:
- Pool water volume
- pump capacity and filtration time
- initial water temperature and desired water temperature (difference between the two temperatures)
- Climate and wind effect
- Pool covered or not (thermal protection, etc.)
- Pool construction; wooden with liner, 100% liner, polyester, above ground, etc.

Formula to roughly calculate the temperature rise of a pool heat pump (April - August):
Temperature rise time (hours) = [volume (m3) x temperature difference (desired temperature - initial temperature) x 1.5] / returned pump power 6.7 kW.

Example with a concrete case for a SUN07:
- 15 m³ pool
- Initial water temperature: 15 ° C / Desired temperature: 28 ° C with temperature difference = 13 ° C (28 - 15)
- Heat pump power: 6,7 kW
- Filtration time: 24h / 24
- Climatic conditions: moderate climate (April - August)
- Wind exposure: low
- Pool cover: yes
- Pool model: standard (without overflow)

Temperature rise time = [15 × 13 × 1.5] / 6.7 = 44 hours or approximately 2 days.

Special formula for early season (April - June):
In the pre-season (with a minimum ambient air of 15 ° C), the previous formula must be multiplied by a coefficient (2.5).
Using our example:
Temperature rise time = [15 × 13 × 2.5] / 6.7 = 73 hours × 2 or approximately 3 days.

IMPORTANT: A pool that is not protected by a pool cover will lose between 4 and 5 ° C per night, while a covered pool will lose between 1 and 2 ° C.

Please note:
This is an estimate based on ideal conditions. There is a big difference between different pools.
For example:
A pool with a wooden perimeter and a cover has less heat loss than a pool With a self-supporting pool wall, which also lose over the large surface of the wall, which is not insulated.
On the other hand, in the summer it is a pool that is 100% exposed to the sun and absorbs more heat through the walls than a pool with a wooden cover.
The floor on which the pool is installed also affects heat loss through direct contact with the ground.

Tip: In the pre-season, do not start the heat pump until the temperature does not fall below 8° C during the nights in the start-up phase, in order to obtain optimal thermal performance.
