Showcasing Our Engineering Expertise

Nestled deep in the rolling hills of the Cotswolds, a beautifully restored old mill house has just stepped into the future of home comfort. The Big Heat Pump Company recently installed the OCHSNER Air hawk 726 , bringing whisper-quiet, high-efficiency heating and hot water to this historic property. Carefully integrated to respect the building’s heritage, the Air Hawk 726 delivers powerful performance without compromising the charm or tranquillity of the rural setting. Its record-breaking low noise levels make it ideal for countryside living, while its ability to achieve high flow temperatures ensures year-round comfort and abundant hot water — even through the chilliest Cotswolds winters. This installation proves that even centuries-old homes can embrace cutting-edge renewable technology, reducing energy bills and carbon footprints while preserving character. It’s a perfect marriage of tradition and innovation — and a shining example of how OCHSNER technology can work seamlessly in heritage settings.

When choosing a heating system, it’s easy to focus on the sticker price or the warranty terms. But the real return on investment comes from choosing a system that won’t need replacing — or re-negotiating service contracts — every 10 years. The heat pump in Unterbergla is living proof: a well-built system, correctly installed, can serve generations.So next time you see a glossy brochure with asterisks around the warranty fine print, ask yourself: Would you rather invest in a promise, or in proof?
