The air in this broiler house was not well circulated. As a result, the warmth and the oxygen were in the upper part of the house while there was a high CO2 concentration on floor level. Multiheat modified the Multiheat warm water heating system to improve the air circulation, resulting in this Multi-Unit. This Multi-Unit does not have the heat exchanger module like the hot water heater has. Instead, the Multi-Unit is being used to take the warm and oxygen-rich air from the top of the building, and divide it through the poultry house at a height of about 1 meter. As a result, there is a 20% energy reduction and the humidity in the broiler house has significantly reduced. The piping was made in a modular way so it is easy to clean.
