Description
Solar hot water, with the cylinder where you want it.
Forced circulation solar systems are designed for installations with large hot water needs, such as apartment blocks, hospitals, sports facilities and hotels, and also for homes, when the tank cannot sit above the collectors for aesthetic or structural reasons.
The Mastersol BL2 consists of a vertical hot water cylinder of 150 or 200 litres, triple energy, with two fixed heat exchangers, and Mastersol selective solar collectors with a total area of 2.5 to 5 m², depending on the model. It comes with flat-roof frames for the collectors, the Mastersol pre-assembled forced circulation kit (solar pump station), a differential thermostat with sensors, a closed expansion vessel, an automatic filling valve, antifreeze and the connection materials for the collectors, in quantities that match the collectors.
The electric heating element is an option: single-phase 3 kW or three-phase 6, 9 or 12 kW, with or without a thermostat. The differential thermostat compares the collector temperature with the cylinder's and starts the circulator of the pump station when the sun can give heat.
The cylinder is lined inside with Direct Glass liquid enamel, fired at 850 °C, 400 microns thick (DIN 4753 Teil 3 & 6). Mastersol has an ISO 9001 quality management system for the production and sale of solar and electric water heaters.
