With a Heating & Cooling Trench Heating system, higher heating outputs and enhanced air flow can be achieved from a low and safe 24V cross-flow, where fans force the air over the finned heat exchanger elements and accelerating the air flow. This makes a Heating & Cooling Trench Heating system an ideal, powerful yet discreet primary heating system or a fast acting secondary heating system, perfect for counteracting downdraught or condensation in highly glazed areas. There is an option to purchase a condensate pump to help remove unwanted liquid from the trench. This product provides the customer with the option of either two pipe or four pipe configurations. The selection of a two pipe or four pipe system largely depends on the piped water system available within a building or sections of a building . With a two pipe water system the supply is either in heating or cooling mode and is switched from one to the other as needed. The two pipe heating and cooling trench heater will deliver warm air when hot water is run through the water supply system, or cold air when it is switched over to a chilled water supply. When a building, or section of a building, has a four pipe water supply, both chilled water for cooling and hot water for heating are supplied in parallel and typically controlled locally via actuators.
