the norm - even in small commercial premises. Schools, small offices, community hubs or modest multi-occupancy blocks are increasingly pairing technologies such as heat pumps, pellet boilers or solar thermal with underfloor heating or low- temperature radiators. But this trend comes certain challenges for system designers and installers and failure


to address them will lead to the production of destructive contaminants, noise, whilst needing to manage the dissolved gases within the system water – principally oxygen and nitrogen.


Positioning a deaerator


It’s not always obvious where to fit a deaerator, but the best location is usually on the flow side. In traditional heating systems that are run at high temperatures, deaerators are usually fitted at the hottest part of the

systems - especially spread across multiple storeys or with underfloor heating loops - the path of gases
