Small Home Comfort: Flamingo's 3.5kW R32 Heat Pump Delivers All-in-One Heating, Cooling, and Hot Water for Tiny Living
In an era where compact living is on the rise—think container homes, tiny houses, and cozy spaces under 35㎡—efficient, multi-functional HVAC solutions are more crucial than ever. Guangdong Flamingo New Energy Technology Co., Ltd. is proud to unveil the NL-B1S/R32, a compact 3.5kW air source heat pump designed specifically for small house projects. Powered by a premium Panasonic compressor and utilizing eco-friendly R32 refrigerant, this all-in-one unit provides seamless air heating, air cooling, and domestic hot water capabilities, ensuring year-round comfort without the bulk or complexity of traditional systems.
Tailored for Tiny Living: Compact Power for Spaces Up to 35㎡
Ideal for container houses or modest dwellings, the NL-B1S/R32 packs robust performance into a sleek footprint of just 960mm x 380mm x 563mm and a lightweight 45kg design. With a rated heating capacity of 3.5kW and input power of 1kW, it delivers reliable warmth even in harsh winters, achieving a maximum outlet water temperature of up to 60℃ for hot showers and underfloor heating. In summer, it switches effortlessly to cooling mode, chilling water down to a refreshing 12℃ for air conditioning via fan coil units—perfect for maintaining a cool oasis in tight quarters.
"This heat pump is a game-changer for off-grid or space-constrained living," says a Flamingo spokesperson. "Homeowners in container projects or tiny homes no longer need separate systems for heating, cooling, and hot water. It's plug-and-play efficiency that fits seamlessly into modern, minimalist lifestyles."
Advanced Features for Smart, Sustainable Comfort
