Bosch debuted its propane air source heat pump at the European trade show ISH in 2023.
The Compress 6800i AW heat pump is designed for retrofit installations and new buildings, both for single and multi-family homes. It has a heating capacity of 3.9 kW to 6.7 kW, measures 800 mm x 1,100 mm x 540 mm, and weighs 143 kg.
It has a coefficient of performance (COP) of 4.8, according to the company’s data sheet. The air source temperature can range from -22 to 45 C. The heat pump can purportedly produce hot water up to 75 C, and up to 65 C with external air down to -10 C. Its seasonal coefficient of performance (SCOP) for heating water to 35 C varies between 4.57 and 4.58, while the SCOP for 55 C applications varies from 3.32 to 3.51.
Bosch claims the Compress 6800i AW is the quietest heat pump in its portfolio. The noise level ranges from 51.2 dB(A) to 57.5 dB(A) during the day, and between 43.4 dB(A) to 46.2 dB(A) during the night. “
