Qube X
Unpressurized hot water storage tank and drain back reservoir
Qube X
There is a polyethylene tank inside filled with energy transfer medium and up to 3 heat exchangers:
- 1 heat exchanger used for providing hygienic hot water
- 2 optional heat exchangers that may be used for:
- 2 additional heat sources like heat pump, any type of boiler, pressurized solar or
- 1 heat source + 1 heat consumer like underfloor heating circuit
- solar thermal connection in a drain back variant
Application
- Renovations of hot water systems
- Large hot water outputs
- Clean hot water in clean spaces
- Where the budget is limited
- Energy efficient installations
- Harshest environment
Benefits
- Lightweight
- Easy to manipulate
- Installer friendly
- Lower transport costs
- Optional electric heater backup (1 or 2)
Hygienic on-demand domestic hot water
- 10÷30% energy savings due to on-demand principle of heating of water for domestic use. It uses energy to heat up the
water only when the user opens the tap - Improved Legionella prevention through the use of continuous flow principle
- Application - in the HORECA industry, kindergartens, schools, hospitals, and residential areas
Water medium for heat transfer instead of glycol
- Water has superior heat transfer properties compared to propylene or ethylene glycol because of a high thermal capacity and
low viscosity. - Unlimited Application - anywhere, including installations where contamination potential is not allowed
- Highest Solar Thermal Efficiency - Water has higher thermal conductivity compared to glycol
- Minimum Maintenance - No need for concentration check up and potential glycol based corrosion
- Low Cost - Glycol solutions are more expensive than water, plus necessary equipment for its handling and maintenance
