Air that is exhausted from a building, to maintain favorable indoor air quality, has been cooled (summer) or heated (winter) to the typical space temperature of 70 to 75F. An air-to-air heat exchanger is the answer to this problem. $436.72 $253.50 Save $183.22. Order) 4 YRS CN . However, instead of a finned-tube heat exchanger used by air-to-air heat pumps, the condenser of air-to-water heat pumps often is a brazed plate heat exchanger. The water heater does two jobs it heats the water that we'll use in the house, and some of that hot water is piped over to the hydronic furnace to heat the air passing over the hydronic coil. Typically, air-to-water heat pumps have a CoP of around 3, which means they generate three units of heat for each unit of electricity used. Cold fresh air flows inside the tubes, is preheated by the exhaust air und then brought into the process - realizing an efficient heat recovery. The pitch is dependent on the heat transfer coefficient on the inside of the tubes. Outdoor Wood Furnaces, Wood Boilers, and Water to Air Heat Exchangers After years in the home heating system business with Alternative Heating & Supplies, our team has expanded to create our own quality Unit heaters, air-handlers, and now a full array of Heat Exchangers.
