Heat Pumps Today

Retrofit with eco-friendly results Q-Ton hits the spot Info www.warmflow.co.uk Warmflow has been keeping families warm across the UK & Ireland for over 50 years. With a state of the art 150,000sq ft manufacturing facility located in Northern Ireland and a sales & distribution oce in Telford, Warmflow has been at the forefront of home heating technological innovation. In this case study, we will focus on heat pumps where Warmflow has helped to significantly boost the energy eciency of a historic rural house, with the retrofitting of a more eco-friendly and cheaper heating system. The Warmflow Zeno air source heat pump was selected as the ideal solution to replace an existing oil boiler at the property – which dates back to Georgian times. The new Zeno heat pump provides heat for a space of around 2,000 sq. ft. Installer Brian Graham recommended this heat pump as he felt is was one of the most ecient appliances in its class. Brian said: “The customer wanted the heat pump installed without a cylinder, so it only generates heat and not hot water. The Citadines Holborn-Covent Garden London originally had gas-fired boilers, which provided potable hot water to the apart’hotel’s 192 apartments and communal breakfast area. Citadines required a replacement that could provide water at high temperatures, whilst ensuring minimal environmental impact. The project at the hotel, which is part of The Ascott Limited portfolio – CapitaLand’s wholly owned lodging business unit – is part of CapitaLand’s 2030 Sustainability Master Plan.

This made it reasonably handy to fit the new heat pump on the exterior wall, and we used the existing flue hole to fit the pipes, so we didn’t need to carry out too much additional work.” GB Renewables Sales Manager Niel said, “The Air Source Heat Pump units can be easily integrated into heating systems, oer excellent energy savings and can help reduce the end user’s carbon footprint,” he added. “In this case, the homeowner wanted a more energy-ecient and environmentally friendly heating solution for her home, and she has expressed her delight at the results. Controls She also commented that the controller was extremely easy to use, with very little training needed. Underfloor heating had already been installed in the property, and heat pumps and underfloor heating systems pair together very well. This is because the underfloor heating requires lower flow temperatures of 35 degrees, meaning the heat pump in turn uses less electricity.” Niel Rumbold, GB Renewables Sales Manager
