Pool Heater using Hydronic boiler

DanDan Posts: 388Member
We have an unheated in-ground pool. We just updated our home boiler system to a high output Buderus G215. Im thinking about options for heating the pool. Im wondering which option would be cheaper or easier to install and run: (1) a separate heater just for the pool, or (2) connect the pool to my Buderus. Any thoughts?

    I would connect to the boiler

    Use a flate plate heat exchanger that is built for chlorinated water. Should be cheaper than installing a whole new heater.

    as a stainless steel HX tank for use as a pool heater.
    Biggest issue is probably getting the piping from the pool pump to the boiler.

    I'd also consider...

    ... a solar pool heater.

    These are typically not that expensive and the heat is free. Plus, they work best when you need them, i.e. all summer. If you build a simple drainback system the collector can even stagnate once the water in the pool becomes too hot.

    plate and frame

    for you a plate and frame heat exchanger will work nicely, just make sure you use a 3 way valve to bypass some of the hot water into the return line for extra insurance as not to shock the boiler. I know buderus can run low, but its a extra precaution.

    not necessary on the Buderus

    he has a G215 which requires no set flow or temp.

  • ever think of....

    Constantin,

    Ever think of putting PEX tube in the pool deck to cool the pool for comfortable feet AND heat the pool?

    We have even used the snow melt in driveways to heat the pool and cool the driveway :-)

    could use pex tube under the pool......

    although it might be difficult getting it under there.

    pools can consume a lot of BTU

    got enough boiler output to drive that type of load?

    I'd also suggest a shell and tube type HX. Triangle or Weil McLain are my favorites, they can handle the pools side flow easily and have large connections.
