Inquiry (采购产品): Heat Exchanger. August 9, 2006 Attn: Tech Support Gentlemen, I am using a (6) ton water to water heat pump to heat water for my hot water electric boiler system and chill water for the chilled water coil in my air handler. I had considered using a Heat Transfer Products SSU-45. They did not think the coil would transfer enough heat to my boiler circuit. The boiler circuit has a Taco 0011 pump which pumps 22 GPM. The heat pump water is supposed to be 130 Degrees F when heating. All suggestions and help appreciated.
