* Nominal power - 16 kW (55 kBTU/h)
The swimming pool heat exchanger B85 achieves its nominal power - so 25 kW - when using water/water as the medium ( without the use of glycol or any antifreeze fluids ) with a temperature delta of 60 °C (between the 2 sides of a HE). It doesn't mean - for example- that the pool heat exchanger B85 is capable to perform 25 kW with low temperature supply - for example in combination with a low temperature heat source as - heat pumps.
In the case of decreasing the temperature delta - between the hot side and the pool side, the final heat transfer, measured in kW, decreases up to the following scheme:
The tubular heat exchanger B85 is not suitable for saltwater, sea water or any water with salt. Check the titanium equivalent - the pool heat exchanger 25 kW titanium for saltwater.
Nominal flow rates of a HE:
When it comes to the pool heating - it is strongly advised - to have a higher flow rate on the pool water side, compared to the heating side (heat source side). This ensures a proper, balanced temperature increase - without the need to introduce a significant volume of hot water into the pool, which could be dangerous and not comfortable
The connections for the media of HE B85:
The suggested pool volume
- Nominally 10-30 m3 with nominal conditions, when having a 60°C temperature difference between the media and appropriate flow rates.
- In practice, with lower temperature supply than the one mentioned, the pool heat exchanger 25 kW can handle smaller pool heating or water tanks such as jacuzzis, whirlpools or hut tubs. It is still one of the smallest heat exchanger of this type on the European market

Heat exchange surface area - is indeed a crucial parameter - determining the efficiency of swimming pool heat exchangers. In fact it is the vital parameter of every type of a heat exchanger, inluding classic Plate models. As we see in the above chart - the B85 pool heat exchanger is the 2nd smallest HE among all the shell and tube heat exchangers in Nordic Tec Catalogue. It is designed so - for small garden pools, but also for spa or hot water tanks (jacuzzis or hot tubs).

The counterflow rule (as we can see in the schema above) means that the heating medium (for example the hot water from the boiler or a heat pump) must flow in the opposite direction to the pool water. The rule is a key, it should be definitely applied in case for swimming pool heating or heating of hot tubs. All Nordic Tec heat exchangers for swimming pools - the direction of flow can be freely changed, the water can flow in both directions. It is important to note however - that forgeting the counterflow principle will definitely reduce heat exchange efficiency, and our pool heating fo may not meet its performance expectations.
If you nned a heat exchanger for hot tub, the B85 by Nordic Tec is an excellent choice. It is capable of effectively heating garden pools - but it it can efficiently heat water in a jacuzzi or hot tub too, even if you require a higher temperature than what is typically found in regular pools. Whether you have an open-flame heating device - like a wood-fired stove or a fireplace for a wood-burning jacuzzi, or an adapted home heating system powered by a condensing boiler, coal boiler, pellets, wood burner, or any other fuel - a heat pump, there is a viable option to connect the water circulation system with the heat source using this specific heat exchanger for hot tub.
