Project: Replace sanitary hot water heating – Air Source Heat Pump
Product: MHI Q-ton System
An air source heat pump installed at Bristol University delivers 2,500 litres per day of sanitary hot water at 65°C. The Q-ton system, manufactured by MHIAE (Mitsubishi Heavy Industries Air Conditioning Europe) has reduced annual running costs by 75% and is saving CO₂ emissions by 67%.
The accommodation block at Bristol University houses 48 students for nine months a year. As with many university halls of residence in the UK, the building was using expensive conventional immersion elements for heating water. The site energy manager was looking for a sustainable solution to be retro-fitted to replace the outdated immersion elements.
The new effective sustainable retrofit solution was fitted by installers ASHP. The MHIAE Q-ton system connects to 1000 litre hot water storage tank to deliver sufficient sanitary hot water to students. The new domestic hot water system has been bought in compliance with the current building regulations and is supplied in line with BREEAM.
