Comparison Against Traditional Systems
The Hydra-Dan Units are highly efficient in comparison to the traditional systems (the gas/oil boiler and the electric heat) used to heat process water. By utilizing waste heat from the R2 City Multi outdoor unit for the Booster and HEX unit, it is possible to supply hot water with high efficiency. Each unit is relatively safe, generates no CO2 emission gases and easy to maintain.
