Producing Hot Water from a Heat Recovery VRV System
Producing hot water from a heat recovery VRV system is one of the most energy-efficient means of providing hot water within a building. We can provide high and low-temperature hot water for bathrooms, wash basins, underfloor heating, and radiators, and even provide heated water for handling unit applications.
Features
- Air-to-water connection to VRV for applications such as bathrooms, sinks, underfloor heating, radiators, and air handling units
- Leaving water temperature range from 25 to 80°C without electric heater
- “Free” heating and hot water production provided by transferring heat from areas requiring cooling to areas requiring heating or hot water
- Uses heat pump technology to produce hot water efficiently, providing up to 17% savings compared to a gas boiler
- Possibility to connect thermal solar collectors to the domestic hot water tank
- Super wide operating range for hot water production from -20 to +43°C ambient outdoor temperature
- Saves time on system design as all water-side components are fully integrated with direct control over leaving water temperature
- Various control possibilities with weather-dependent set point or thermostat control
- The indoor unit and domestic hot water tank can be stacked to save space, or installed next to each other, if only limited height is available
- No gas connection or oil tank needed
- Connectable to VRV IV heat recovery
