Product Introduction
Air vent valve, purpose and operation: Delivery temperatures into the floor system should be maintained between 37 and 44 Degrees C. Temperatures exceeding 44 degrees should be avoided as this may damage the floor and will shorten the working life of the pipe. The air vent valve will control the input blending return water from the floor with hot water from the heat source. Where the heat source is supplying at high temperatures or an uncontrolled appliance such as a wood fire or solar is applied, a buffer tank is recommended.
