88 kW pool heat exchanger for effective pool water heating

88 kW shell-and-tube heat exchanger for heating pool water

Technical Details:

  • Nominal capacity of a pool heat exchanger B300 - 88 kW

A 88 kW pool heat exchanger achieves its power output when using water-to-water media, assuming a temperature difference between them of 60 degrees Celsius (100% efficiency).

Efficiency in the case of temperature difference between the media:

60 °C = 100%
50 °C = 85%
40 °C = 70%
30 °C = 55%
The nominal flowrates values are also required to achieve the declared capacity.

Using glycol as a heat transfer medium reduces efficiency to 85-92%, depending on the glycol concentration. Take it into account if you heat up your pool with solar collectors or monoblock heat pump.

  • Nominal flowrates: 42/325 l/min (one of opportunities)
  • Permitted media - all except so called agressive media, including ammonia and salt/sea water

If you want to use salt water you should use a exchanger made of titanium - for example a titanium heat exchanger B300 of 88 kW

  • Maximal temperature - up to 208°C (406 °F)

Basic application of this pool heat exchanger - B300

  • The primary application is as a heat exchanger for heating water in pools, spas, or hot tubs
  • Heat exchanger for systems with low pressure drops - e.g., for underfloor heating (with proper selection)
  • Defrosting driveways and parking lots.
  • Fireplaces, boilers, and other heating devices related to central heating and domestic hot water
  • Industrial application as oil coolers, engine coolers, drive systems, and sample coolers in boiler installations

Connecting a B300 heat exchanger for heating a pool

  • K1 - heating water - IN
  • K2 - heated water - OUT
  • K3 - heated water - IN
  • K4 - heating water - OUT

Pool heat exchangers, including models used for heating water in the pool such as all those from the Nordic Tec B-Series, are connected in a counter-current manner to achieve maximum heat transfer efficiency. Failure to connect them in this way results in significant limitations in efficiency, effectively leading to the dysfunction of pool heating.

Tubular heat exchangers - not only for heating pool water

Pool heat exchangers are devices designed to efficiently and economically heat water in a pool in cooperation with a specific heat source, which can be a heat pump, solar panel, as well as traditional heat sources - like a heating boiler or fireplace. Unlike classical HE, modern pool heat exchangers are not constructed with plates (such a design - like a plate heat exchanger -  would create too much resistance to flow, resulting in high pump consumption at relatively high flow rates of pool water). To generate minimal pressure losses, these tubular heat exchangers are tube-based, allowing water to flow freely.
Essentially tubular heat exchangers are essential components of pool heating systems, regardless of the primary heat source in the heating setup.

Heat exchanger for swimming pools Nordic Tec B300 in marinization

Heat exchangers for swimming pools - including the B300 model, are also suitable for marinization - as boat engine coolers, using onboard water as the cooling medium. This type of construction is called engine marinization using a shell-and-tube heat exchanger or simply engine marinization. The reason why these models of tubular heat exchangers are chosen instead of cheaper plate counterparts is the same as that which determines their use for pools ( relatively low pressure losses, which translates into cooling efficiency ).
Additionally, pool heat exchangers are less prone to clogging compared to plate heat exchangers, having relatively small gaps - between the plates susceptible to dirt accumulation. While this is not a problem in heating installations using pre-treated water, it would be a serious issue in marinization. This is a secondary application discovered by individuals from another industry - who began to utilize these models independently of their main purpose, which is pool heating.

Selection of a pool heat exchanger for marinization | B300

When making a selection of a pool heat exchanger for marinization for a boat engine - to function as a cooler, it should be chosen by converting the engine power into kW. Typically the engine power is given in HP; after conversion to kW, it should be as compatible as possible with the nominal power of the heat exchanger, also given in kilowatts. If possible, the heat exchanger should be slightly oversized, but if not feasible, it should be selected so that the nominal power is not less than 90% of the engine's nominal power given in kiloWatts. In this case  we can guarantee that the cooler will function efficiently for a considerable period.

However, it's important to remember that stainless steel pool heat exchangers are not intended for use with seawater or saltwater. Similarly to pools with seawater, it's worth replacing them with a titanium heat exchanger. Titanium heat exchangers, though, are significantly more expensive, and despite this, many people choose to use steel models even in vessels navigating the sea, knowing that after some time, the heat exchanger may develop leaks or malfunction. When used with seawater, this usage is not covered by warranty.
