Solareast Heat Pump Ltd. offers a reliable and efficient R290 air-to-water heating and cooling system
Outlet Water Temperature Up To 75℃
The R290 Air To Water Heat Pump is designed for heating and cooling, making it compatible with floor heating and cooling, air source floor heating, fan coil units, and radiators.
It can heat water up to 75°C, making it ideal for cold climates.
When paired with a water tank, it ensures a steady supply of hot water for homes and businesses.
This high quality air to water heat pump is designed for long-lasting efficiency.
Multi-Temperature Zone – Easy Control
This heating and cooling system allows users to set different temperatures for different rooms.
You can adjust heating and hot water settings separately, making it more convenient and energy-efficient.
The system automatically adjusts the temperature to save energy and keep indoor conditions comfortable.
It is a comfortable air to water heat pump, perfect for customized home heating.
Quality Assurance
Every air to water heat pump for floor heating undergoes multiple quality tests before shipping.
Each unit undergoes four essential quality inspections:
✅ Incoming Materials Inspection – Ensures that only high-quality raw materials are used.
✅ Helium Inspection – Detects even the smallest leaks for maximum efficiency.
✅ Halogen Inspection – Ensures no refrigerant leakage, improving reliability.
✅ Commodity Inspection – Verifies overall product quality before shipment.
Before delivery, all units undergo a final halogen test, ensuring only the best-quality and stable air to water heat pump performance for long-term reliability.
Laboratory
Solareast has a $3 million testing lab for heat pump systems.
We test our heat pumps from -30°C to 52°C to ensure they work in all climates.
Our labs include:
✅ Explosion-proof testing – Ensures safety under extreme conditions.
✅ Water flow testing – Optimizes heat transfer and energy use.
Certificates
Our high strength air to water heat pump meets strict global standards.
Certifications include:
✅ CE – Meets European safety and performance requirements.
✅ KEYMARK – Recognized certification for heat pump quality.
✅ ErP – Ensures energy efficiency.
✅ BAFA – Eligible for government subsidies in Germany.
✅ MCS – Certified for renewable energy systems.
✅ SG Ready – Works with smart energy grids.
Our production uses advanced automation for better quality:
✅ Laser Cutting – Creates precise parts for longer-lasting products.
✅ Powder Coating – Protects the surface for better durability.
✅ High-Pressure Foaming – Improves insulation and saves energy.
✅ Bending Technology – Ensures perfect assembly.
The 18KW R290 Air To Water Heat Pump is built for energy efficiency. It uses less electricity than traditional systems. Thanks to its high COP, it produces more heat with less power, helping users save on energy costs.
Yes! Our high-quality air-to-water heat pump works well in temperatures as low as -30°C. It has defrosting technology to keep it running smoothly in winter.
Installation usually takes 1-2 days. A certified HVAC installer will connect the heat pump water heater to your system. If used for hot water, a water tank is recommended.
The price of a heat pump is important for buyers. If you are comparing the price of heat pump models, Solareast provides cost-effective and energy-efficient solutions.
Our energy saving air to water heat pump helps lower electricity bills.
Customers get top heat pumps that use eco-friendly R290 refrigerant.
Choosing the best heat pump for heating means getting high efficiency, stable performance, and long-term cost savings.
If you are looking for the best heat pump for heating, Solareast's R290 model offers excellent energy efficiency, low operating costs, and long-term reliability.
