Thermostatic kit Watts Italy for solar system and wall-mounted gas boilers
Automation for connection of the solar collector with the gas boiler and the cooperation between them.
Provides uninterrupted hot water to the user for installations that use solar in conjunction with other heat source such as boiler.
Absolutely autonomous, running without power.
Application:
- If the water in the solar tank is already too hot (above the desired setpoint of 45oC), it will automatically mix with cold water through the heat sink so that the water at the outlet has a safe constant temperature.
- When the temperature in the tank is too low (below 45oC), switching to a heat source (gas boiler) which will heat the water and then mix to reach the set-up temperature for the various hot water needs at the building.
Features & Benefits:
- Fully autonomous: energy saving.
- No wires and sensor cables: save time.
- Easy installation for new or old facilities.
- Distribution of hot water to the existing grid at an ideal temperature setting.
- Integrated protection using a thermomechanical valve, and an automatic switching valve. Combination of valves in KIT for easy installation.
Technical data:
- Messon: Drinking water
- Switching valve opening temperature: 45 ° C (factory setting).
- Temperature control valve temperature range: 30oC - 65oC
- Maximum static pressure: 10 bar
- Hot and cold water flow pressure: 0.2 to 5 bar
- Hot water supply temperature: 52 * to 110oC, cold water: 5 to 20oC
