Forced circulation systems
Forced circulation systems are the most widespread systems in Central and Northern European countries, as low temperatures are a limiting factor in the location of the boiler. This system consists of the collector, the boiler, the boiler room boiler, the support base, the solar station, the differential thermostat, temperature sensors and various accessories.
The biggest advantages of the forced circulation system, compared to the hot water heater, are the following:
- Less heat loss of the boiler, as it is installed indoors
- System automation
- Greater system flexibility, resulting in greater overall plant efficiency
