The Hybrid maintains a balanced temperature throughout the year by incorporating some simple, yet sophisticated technology. The system is comprised of a number of 'Hybrid' units (typically one per zone), interconnected by way of a piping loop. The temperature balance is maintained by absorbing heat from, or rejecting heat to, the water in the loop as needed. Each unit operates independently with its own thermostat. This allows individuals to select the temperature suitable for that space. During much of the year the heat input to the loop from cooling will offset the heat withdrawn from the loop for heating, creating a highly efficient, balanced system. A small boiler and fluid cooler are installed for instances when either heating or cooling loads are predominant. A user friendly central panel allows you to control the pumps, boiler and cooler.
