HONWO’s R290 Monoblock ATW Heat Pump brings together the most advanced features in modern HVAC: ultra-low-carbon R290 refrigerant (GWP 3/ODP 0) for a truly green footprint, industry-leading seasonal efficiency up to A+++ at 35 °C water temperature, and high-temperature output up to 80 °C. Engineered for extreme climates, it delivers hot water at 55 °C even at –25 °C ambient and 75 °C at –10 °C.
Uses natural R290 refrigerant with GWP of only 3 and zero ODP.
Achieves seasonal energy efficiency class A+++ at 35 °C water temperature.
All-DC inverter technology (compressor, fan, pump) for minimal power draw and stable COP up to 6.1.
Provides hot water up to 75 °C at –10 °C ambient and 55 °C at –25 °C ambient.
Max leaving water temperature (LWT) up to 80 °C (without e-heater assisted).
Sound pressure as low as 35 dB(A) at 3 m for whisper-quiet comfort.
Six-stage antifreeze protection ensures stable winter performance.
2-zone independent temperature control for personalized comfort and bill savings.
Smart app integration with remote monitoring, software updates, and fault alerts.
Hermetic, explosion-proof control box for enhanced reliability.
Color touchscreen controller with intuitive UI, Wi-Fi, Modbus, and multilingual support.
Noise-reduction casing with shock-absorbing mounts.
Equipped with the industry-standard SG-Ready interface, this heat pump can receive external load-management signals—such as time-of-use price cues or grid-frequency notifications—to automatically adjust its runtime and maximize self-consumption of onsite renewables (e.g. PV) or participate in demand-response programs. This ensures you get the lowest operating costs, helps stabilize the public grid during peak periods, and makes your HVAC system “future-proof” as Europe’s energy networks evolve.
Grid-Friendly Demand-Response: Temporarily shed or shift heating to off-peak times at the grid operator’s signal, reducing strain on the network and earning potential tariff rebates.
PV-Smart Operation: When paired with a solar inverter or smart energy manager, the SG-Ready interface lets the heat pump soak up excess PV generation, storing solar energy as heat rather than exporting at low feed-in tariffs.
Standardized BWP Certification: Conforms to the German Heat Pump Association’s SG-Ready specification, guaranteeing compatibility across all major European smart-grid platforms.
By combining R290’s ultra-low GWP and high COP with SG-Ready intelligence, you gain a truly low-carbon, low-cost heating solution optimized for tomorrow’s energy systems.
Residential Homes: Replace gas boilers with zero-carbon heating and hot water.
Multi-Zone Apartments: Simultaneously manage living room, bedroom, and study comfort.
Commercial Spaces: Offices, small hotels, and retail stores seeking low-noise, high-efficiency heating.
Extreme Climates: Reliable heating even at –25 °C, ideal for Northern European and cold-region installations.
