Hello all and Merry Christmas,
We are in the process of planning the replacement of our 50-year old heating boiler serving a residential block of 12 flats with a total of 60 radiators. It is a vented single-pipe heating system, which has not been properly maintained, and we only recently installed a commercial magnetic filter to filter out as much sludge as we can prior to the replacement. We will be installing a 100kw boiler. I know that we could also install two 50kw boilers, but this is a matter for a different post. A heat exchanger will protect the new boiler from the old vented system. Our installer suggested that we use the following pool heat exchanger, because it has 2 inch connections matching our 2 inch pipes and also has larger waterways so that it does not get clogged.
POOL HEAT EXCHANGER NORDIC B300 88KW (300KBTU/H)
Pool Heat Exchanger NORDIC B300 88kW (300kBTU/h) - https://nordictec-store.com/b-line-pool-heat-exchangers/171-pool-heat-exchanger-nordic-b300-88kw-300kbtuh.html
How suitable is this pool heat exchanger for our purposes? I am concerned that it may not be as efficient as a normal heat exchanger. Also, the suggested heat exchanger is 88kw, yet the new boiler will be 100kW.
I can order a normal heat exchanger with 2 inch connectors and to address the clogging issue I could use a CMX inline filter like this one here from Addey: MagnaClean CMX® | ADEY - https://www.adey.com/product/magnaclean-cmx The medium and large models can also be used inline.
I would appreciate your feedback.
Below is information for the pool heat exchanger:

Pool&Spa Heat Exchanger B300
Nordic Tec B-Serie
Nominal Capacity: 88kW
based on 60 °C difference between heating and heated medium (water to water),
with counter-courent work
Material: Stainless steel 316L
Heat Exchange surface: 0.64 m²
Connections: 2x 2" & 2x 1 1/2"
Important Note: If one of media is glicol, the capacity will be only 85-90% of nominal one
Pool&Spa Heat Exchanger B300
Nordic Tec B-Serie
Technical Details:
Nominal value 88kW (power/capacity) is based on 60 °C difference
between heating water and pool water (calculations are different for other media).
If there is other temperature difference, the capacity is following:
60 °C = 100%
50 °C = 85%
40 °C = 70%
30 °C = 55%
The nominal flowrates values are also required to achieve the declared capacity.
Nominal flowrates: 42/325 l/min (one of opportunities)
