UniQube SQ-BPSW Drain Back
Solar Storage Tank - Domestic Water Heater - Stratified Separator Storage Tank
UniQube SQ-BPSW Drain Back
UniQube Drain Back is central heating tank with integrated drain back reservoir made of long life corrosion resistant thermal plastic. This system do not require a check valve, air vent, pressure gauge or expansion tank. Draining reservoir is connected to a heat exchanger that transfers the solar energy to the main solar storage tank.
Installer friendly and space saving
UniQube Drain Back is central heating tank with integrated drain back reservoir made of long life corrosion resistant thermal plastic. This system do not require a check valve, air vent, pressure gauge or expansion tank. Draining reservoir is connected to a heat exchanger that transfers the solar energy to the main solar storage tank.
UniQube suitable for all climates
When designing solar thermal systems, especially in very hot or very cold climates, drain back solar thermal systems are ideal solution.
Solarico drain back tank allows all the water from solar collectors and related piping connections to drain back into the upper reservoir, protecting the system from freezing and overheating.
Heat transfer medium
Drain back solar systems can use water as heat transfer medium! Water has high specific heat capacity, low viscosity and it is inexpensive.
Solar‐supported heating systems
UniQube drain back solar systems can handle summertime overheating. Therefore it is suitable for the systems with oversized collector arrays, which have been upsized to supplement space heating during the heating season.
