When it comes to modern home heating, flexibility and reliability are key. That’s where Tongyi’s air to water heat pump system takes performance to the next level with two advanced features: the cascade function and the Additional Heating System (AHS).
Cascade Function: Scalable Heating for Every Need
The cascade system allows up to 8 heat pump units to work together under one controller, perfectly balancing household heating and hot water needs. Whether it’s keeping your home warm or ensuring a steady supply of hot water, multiple units can operate simultaneously for different tasks—or share demand between them. This makes the air to water heat pump system ideal for larger households or commercial spaces where energy demands fluctuate.
Additional Heating System (AHS): Backup Power When You Need It
Even the most efficient systems may require a boost during peak demand or in extremely cold weather. That’s where the AHS (Additional Heating System) comes in. It integrates seamlessly with the heat pump setup and can include:
- A backup heater or gas boiler, controlled by the unit’s smart system.
- Solar and tank booster heaters (TBH) for raising domestic hot water temperature.
- A 3-way valve that automatically switches between heating mode and DHW (domestic hot water) mode.
This ensures comfort and efficiency all year round, giving homeowners peace of mind that hot water and heating will always be available, no matter the weather.
Smarter Living, Greater Savings
By combining cascade operation with the flexibility of the AHS, Tongyi’s air to water heat pump system adapts to different household sizes, weather conditions, and energy needs—delivering both efficiency and reliability.
