Turning waste heat into hot water


London food distribution charity Felix is using BEIJER REF SEC200 heat recovery technology to help deliver hot water with almost zero energy consumption. Felix rescues surplus food and delivers it to community organisations and schools. The SEC200 was installed at its Deptford site as part of a major refrigeration project. The system recovers waste heat from


the refrigeration plant and uses it to supply hot water to the site’s new canteen, utility room, shower room and first-floor toilets. “Performance has been excellent,” says William Liggett at KDH Projects. “After several months of continuous operation, the data shows almost zero energy


consumption for hot water production. The SEC200 is recovering so much waste heat that it’s effectively delivering free hot water. The results match, and in some areas exceed, our expectations.” William adds that the standout benefit


for both contractor and customer has been the reduction in hot water energy use. “The system has virtually eliminated the need for traditional water heating, delivering significant ongoing cost savings.”


The Deptford installation follows earlier SEC200 projects for Felix, with the charity now installing the technology across new sites. ▄ www.beijerref.com


Historic church replaces ageing heating system


St Peter’s Scottish Episcopal Church in Galashiels has replaced its ageing gas heating system with HERSCHEL INFRARED Halo heaters as part of its move towards lower carbon heating. The Category C listed


church, which is more than 175 years old, had been facing challenges from high ceilings, large open spaces and limited insulation. Its previous gas system was also becoming increasingly difficult and expensive to maintain. Following research into


different heating technologies, including heat pumps, electric radiators and infrared systems, the church selected Herschel’s infrared heating. Three Halo 9.6kW heaters were installed in the nave, alongside two Horizon heaters positioned to avoid obstructing the building’s stained-glass windows. The installation was


completed in around a EIBI | SEPTEMBER 2026


week by Herschel Installation Services, including cabling, controls, commissioning and heater fitting.


The church says the new


system has reduced energy use, with heating now switched on around half an hour before services compared with more than two hours previously. It also says


maintenance requirements have been significantly reduced. The system includes


smart controls, allowing heating to be adjusted remotely when the building is used outside of regular services. The project was completed on time and within budget. ▄ www.herschel-infrared. co.uk


Upgraded hot water system for busy dairy farm


A family-owned dairy farm in County Down is benefitting from the replacement of an expensive-to-run electric heating system with three NAVIEN NPE tankless water heaters. The simple switch from electric to gas has significantly reduced operating costs, with estimated savings of 30–40%. The new Navien system runs


automatically, providing instant hot water 24/7, with gas being topped up only once a month. A reliable hot water system is crucial for feeding calves, cleaning and looking after sick animals and has


improved the overall efficiency of the everyday tasks at the farm. Automatic monitoring and scheduled


topping-up of gas usage means that staff can rely on the system without needing to keep an eye on it, giving them the time back to carry out more essential tasks on the farm. Each water heater tracks its own gas consumption, allowing customers to remotely check when the gas needs topping up by using a connected app from their chosen gas company that comes to top up gas once it has hit a certain level. The NPE water heaters can be joined


together if there is a high demand, making it ideal for busy farms. Features include freeze protection and easy-to-access components, so repair or maintenance can be quickly carried out. ▄ Navien.co.uk


Heat pumps support hospital redevelopment


Air source heat pumps from PANASONIC Heating & Cooling have been installed as part of the redevelopment of Goodmayes Hospital, helping provide a fully electric heating system for the refurbished NHS facility. The Victorian building, which had stood unused for decades, was redeveloped by North East London Foundation Trust with support from M&E consultant Donabie Associates and heating systems specialist DiscreteHeat. The project required an alternative to gas heating while meeting the demands of a modern healthcare environment. Panasonic supplied a


cascade system comprising three 30kW Aquarea M Series T-CAP air source heat pumps. Two units provide heating, while a third acts as a standby unit during maintenance. The system was selected for its ability


to operate at low water temperatures while maintaining heating output in colder weather. The heat pumps are


paired with DiscreteHeat’s ThermaSkirt EasyClean heating system, which combines heat distribution with the function of a skirting board. The system was chosen after alternatives such as ceiling-mounted radiant panels and underfloor heating were ruled out


because of the building’s historic features. The pairing of


low-temperature emitters with Panasonic’s high-efficiency heat pumps ensures optimal system performance throughout the year. This approach helps reduce energy consumption, lower operational costs, and maximise renewable heating benefits.▄ www.aircon.panasonic. eu/GB_en
