Super-insulated pipework

4-pipe system for heating and domestic hot water

The benefits of placing the heating and the domestic hot water pipes in the same insulation system are lower investment costs, shorter installation time and reduction of energy losses.

The dimensions are available from 20 to 125mm. Any combination of pipes can be used which results in an easy-to-use flexible system.
