Sealed System Heating Equipment
The central heating system most commonly used in Europe and other parts of the world is a sealed system. Ease of installation makes it particularly attractive to the installer, as sealed system alleviates the need to fit, feed and vent tanks in the central heating system.
- System Flexibility - due to components sitting alternatives
- Cost Savings - due to considerably reduced installation time
- No feed and expansion tank - hence avoiding 'pumping over' problems, risk of freezing up etc.
- Longer Life - Due to higher system pressure, boiler noise (localised heating) is significantly reduced or eliminated
- Low Maintenance Cost - as equipment is virtually maintenance free other than for periodic operational checks
- Water supply (water regulations) G.24.1 and 24.2 compliant filling loop
