sizing water to water heat exchanger

Tony Conner_2

... I'm not sure what you mean by "ambient temp in the equation"? When I refer to not wanting the hot side temp to drop below a certain minimum, I'm thinking about a non-condensing boiler that may not want to see really low return water temps. Typically, the water to water HX itself doesn't care. Is that what you meant?

sizing water to water heat exchanger

I am installing an outdoor wood furnace and I need a heat exchanger to hook the wood stove into my current hydronic heating system. I don't know the BTU's of the wood stove I am estimating to be around 300,000. My furnace is around 110,000 btu's.

HX manufactures have

sizing charts for this. you will need to furnish more info however. Temperatures, delta t, flow rates, amount of btu's to be moved, fluid type, etc.

Contact a rep or manufacture of heat exchangers. tony Conner is around here somewhere. He knows a ton about sizing and supplying heat exchangers.

It's....

... pretty easy to figure - you need to provide the fluids (water, glycol - what kind and percentage, etc), the inlet and outlet temps along with the GPM on the cold side. After that, the only other bit needed is the hot side inlet temp, and the outlet, if there's a point you don't want to drop below. The hot side GPM will be calculated off that. It's simple to shuffle things around, depending on the available data. Sometimes people ask "How much water can I heat with this input?" As long as most of the info is available, the rest can be calculated.

Thanks for the plug, HR.
