Is there a boiler that can double as a swimming pool heater?

Makes a indirect heater that will work off a properly sized boiler. http://www.htproducts.com/products/pool/index.html

    Boiler & Swimming Pool Heater

    Is there such a thing as a boiler, that can have one open loop for heating a swimming pool, and the traditional closed loops for steam heat (baseboard) radiators?

  • Not that I'm aware of because cast iron doesn't like chlorine among other things and there is the problem of oxygen in the water too. There ARE pool heaters that can be used as a zone off your boiler though. I put in a Weil Mclain type for my neighbors and it works quite well.

    We have the Maxi-Flo pool heater, that is a tube and shell design that would isolate the boiler from the pool water. It is available from 95K to 400K.

    All you need is a heat exchanger between the pool and the boiler, and you can use any boiler you want to heat a pool.

    While the heat exchangers work, be careful about how they are piped to your existing boiler - assuming it is a conventional atmospheric non-condensing type.

    You need to be aware / prevent a condition called sustained flue gas condensation. Simply put, if the return water temp to your boiler is too low, the flue gases will condense forming acid. They can rot out your exhaust piping, void your warranty. You could also thermally shock your boiler and cause it to crack or leak.

    I am not trying to scare you from using these products, they work great - just be sure your system is controlled and piped properly to prevent this

    Pool Heat

    I've been heating my pool for 9 years with an Energy Kinetics System 2000 (approx 95,000 btu input oil)and a stainless steel plate heat exchanger. It is piped just like any other zone and the thermostat is in the return line coming from the pool. It raises 18,500 gallons of water from mid 50 degree range to 80 in 2 days. Some care needs to be taken to prevent cold water from returning to the boiler for too long. A bypass would be a good way to regulate it. I have not had any corrosion issues and have used brass barb adapters to make the connection between the filter and the heat exchanger.
