Furnace Exhaust Heat Recovery System

Cain industries is a leading designer and producer of combustion exhaust heat transfer products.

Furnace exhaust heat recovery system. It is a gas to gas heat exchanger placed on the stack of the furnace that preheats incoming air with exhaust gas. A healthy climate heat recovery ventilator hrv helps keep your air fresh without creating a potentially uncomfortable situation. Performance of upstream and downstream equipment must be considered pressure drops and thermal design consitions of existing equipment will be affected by the retrofit. All hrvs direct a supply of fresh outdoor air into your house while exhausting stale indoor air outside.

Waste heat recovery from exhaust streams may complicate or alter the performance of exhaust duction or environmental control and abatement equipment. Holding the heat a heat recovery ventilator hrv is similar to a balanced ventilation system except it uses the heat in the outgoing stale air to warm up the fresh air. That s the insides of one here. Designs rely on tubes or plates to transfer heat from the exhaust gas to the combustion air and keep the streams from mixing.

They reduce the costs of heating ventilated air in the winter by transferring heat from the warm inside exhaust air to the fresh but cold outside supply air. Energy recovery ventilation systems provide a controlled way of ventilating a home while minimizing energy loss. Understanding the heat recovery ventilator system an hrv is a fan equipped box about the size of a small mechanic s tool chest. This is our 20yrs old inefficient furnace when connected to the furnace exhaust heat recovery system heat from furnace exhaust that is vented out of the structure being heated enters the fehrs and.

A recuperator is the most widely used heat recovery device.
