BTEsolar Revolutionizes Green Heating: Unveiling Innovations in Air-to-Water Heat Pumps

In the global pursuit of clean and sustainable energy solutions, air-to-water heat pumps have emerged as a cornerstone of eco-friendly heating systems. BTEsolar, a front-runner in the heat pump industry, is spearheading this transition with its cutting-edge technology, rigorous certifications, and customer-centric product lineup—all detailed in its comprehensive Heat Pump Catalog(OCR).pdf. From demystifying heat pump basics to launching game-changing new products like the Thermalux Series, the company is redefining what it means to deliver efficient, low-carbon heating for homes and commercial spaces worldwide.

What Is an Air-to-Water Heat Pump? The Science Behind Sustainable Heating

Heat pump water heater is a kind of high-efficiency and energy-saving hot water equipment. It adopts advanced heat pump technology to convert low-temperature heat in the air into high-temperature heat energy, and provides users with a large amount of constant-temperature hot water.

Heat pump water heaters bring comfort and convenience to your life. 

Devotion Thermax Heat Pump

Devotion Thermax Air to Water Heat Pump is a sustainable. Low-carbon heating solution for your home.While most other heating systems rely on fossil fuels. Devotion utilizes renewable sources of energy to generate heat by combining 25% ectricity and 75% outside air, making Thermax heat pump a green alternative to your old boiler.

The working principle hinges on a refrigerant cycle: the heat pump absorbs ambient air heat (even in cold climates), amplifies it via advanced compressors, and transfers it to water for heating systems (like radiators, floor heating, or fan coil units) or domestic hot water use. For users, this translates to constant-temperature hot water, consistent indoor heating, and long-term energy savings—addressing the key pain points of traditional heating: high carbon output, fluctuating temperatures, and excessive utility bills.

BTEsolar: A Trusted Name Backed by Global Certifications

Credibility in the heat pump industry starts with compliance to strict international standards, and BTEsolar leaves no room for compromise. As outlined in the catalog, its products boast a suite of prestigious certifications, including CE, EMC, MCS, RoHS, and Keymark—ensuring they meet safety, performance, and environmental benchmarks across Europe and beyond. The company also adheres to ERP Energy Labeling requirements, with many models achieving top-tier energy ratings, a testament to their exceptional efficiency. 

Headquartered at No.2228 Jinghua Avenue, Economic Development Zone, Dezhou, Shandong, China, BTEsolar operates with a clear mission: “To create green and comforts” and maintain “leadership in clean and sustainable heating energy”.

Product Spotlight: Thermax Series—Proven Performance for All Climates

The Thermax Series, a star product line in BTEsolar’s catalog, is designed to tackle diverse climate challenges while delivering uncompromising efficiency. Available in two installation forms—MONO (all-in-one) and Split—it caters to different space and layout needs, making it versatile for homes and small commercial buildings.

Key Variants of the Thermax Series

Thermax R32 MONO A: Equipped with a HIGHLY R32 DC inverter compressor, this model operates continuously even at -25℃ (-13°F) and delivers outlet water temperatures up to 60℃ (140°F)—ideal for cold regions. Its R32 refrigerant balances efficiency with environmental responsibility, though it is complemented by the even greener R290 in later series.

Thermax R32 MONO B: Adds optional 3kW~9kW PTC electric auxiliary heating (via Heatwell components) for extreme cold, plus a 3.5-inch color LCD touch screen controller and WiFi/4G/APP remote control. The unibody anodized aluminum panel enhances durability while maintaining a sleek design.

Thermax R32 MONO L: Built for larger capacity needs (10kW/12kW/16kW), it features a Mitsubishi R32 DC inverter twin rotary compressor for enhanced performance. It also includes “SG Ready” technology for automatic smart grid integration, allowing the pump to adjust energy use based on peak/low electricity hours—cutting heating costs further.

Thermax R32 Split: Offers flexible installation with up to 9m copper pipe connection, perfect for spaces where the outdoor unit needs to be placed away from the indoor system. The R32 refrigerant charge is limited to <1.8kg, meeting strict safety standards. 

Across all Thermax models, efficiency is a constant: COP (Coefficient of Performance) values reach up to 4.81 for heating at 35℃ outlet water temperature, meaning for every 1kW of electricity input, users get up to 4.81kW of heat output—far exceeding the efficiency of gas boilers.

Game-Changer Alert: The New Thermalux Series with Low-GWP R290 Refrigerant

In 2023, BTEsolar raised the bar with the launch of the Thermalux Series—its latest high-end, triple-supply heat pump line. The standout feature? The use of R290 refrigerant, which has an ultra-low Global Warming Potential (GWP) of just 3. This is a massive leap forward compared to traditional refrigerants like R32 (GWP=657) or R410A (GWP=2088), making the Thermalux Series a game-changer for eco-conscious consumers and businesses.

Why the Thermalux Series Stands Out

Extreme Climate Adaptability: It operates reliably at temperatures as low as -35℃ (-31°F) and delivers outlet water temperatures up to 75℃ (167°F)—outperforming the Thermax Series and ensuring comfort even in frigid regions.

Quiet Operation: The HIGHLY precision frequency control silent R290 compressor reduces noise by up to 6dB in sensitive frequency bands, with operating noise as low as 50dB(A) within 1 meter—perfect for residential areas.

Enhanced Vapor Injection (EVI) Technology: EVI boosts heating performance and energy output, especially in low temperatures, ensuring consistent heat even when ambient air temperatures drop sharply.

Integrated Hydraulic System: For added convenience, the Thermalux Series can be paired with BTEsolar’s Hydraulic Mono system—an all-in-one solution that includes a 250L domestic hot water tank, 60L buffer tank, and expansion tank. This eliminates the need for separate water system installations, saving time and space for installers and users alike.

Beyond Heating: Poolar Series for Commercial & Recreational Needs

Recognizing the demand for efficient pool heating, BTEsolar’s Poolar Series caters to swimming pools ranging from 50 to 500 square meters. With single modules spanning 7kW to 28kW, it is ideal for hotels, resorts, and large residential complexes.

Key features of the Poolar Series include: 

Anti-Corrosion Spiral Titanium Tube: Ensures durability in pool water environments, resisting rust and wear for long-term use.

R32 DC Inverter Compressor: Delivers efficient heating with EEV (Electronic Expansion Valve) control for precise temperature regulation.

Smart Control: Optional 4.1-inch color touch screen remote control with WiFi/4G/APP support, allowing users to monitor and adjust pool temperatures remotely—optimizing energy use and ensuring the pool is ready when needed.

Real-World Application: Certifications, Compatibility, and User-Centric Design

BTEsolar’s heat pumps are not just technologically advanced—they are designed to integrate seamlessly into existing heating systems. The catalog highlights that Thermax and Thermalux models are compatible with solar collectors, gas furnaces, and boilers, making them a flexible addition to any energy setup. 

For example, in cold European climates, the Thermax MONO L’s -25℃ operation and AI defrosting system (with multi-level intelligent defrosting) ensures uninterrupted heating during winter. In contrast, the Thermalux Series’ -35℃ capability makes it suitable for harsh northern regions like Scandinavia. Both series also support up to 8 units in parallel, controlled by a single controller—ideal for larger commercial buildings requiring scalable heating solutions. 

Safety and sustainability are further reinforced by RoHS certification (ensuring no hazardous substances) and Smart Grid Ready functionality, which allows the heat pumps to use excess electricity from photovoltaic systems—turning solar energy into usable heat and reducing reliance on the grid.
