Heating and Ventilation

structrual health

The founders of Cornerstone have a significant history dealing with fire and flood incidents and, our clear knowledge of structural and atmospheric moisture behaviour in affected buildings alongside a transparent reporting process was soon noticed by clients including NHBC, Private Surveyors and Social Housing landlords seeking to determine root causes for a reported damp, condensation and mould problem.

With these prevailing issues every winter period, Cornerstone are conscious of the need for a uniform approach that will serve to deliver credible diagnosis alongside specific guidance for building occupants and structural owners/landlords/managers with particular emphasis on the safety of those who use and occupy the buildings.


extra boost

The Radfan Extra Boost is the latest model in the Radfan range, but designed with air/ground source heat pump system applications in mind.

Just as the Classic Radfan, this model helps make residents feel warmer more quickly so potentially reducing their energy bills, and reduces the conditions which promote the growth of mould.

energy costs

Cottsway is West Oxfordshire’s largest housing provider and has over 5,100 homes across Oxfordshire, Gloucestershire, Wiltshire and Worcestershire. Cottsway are working to reduce carbon emissions and energy costs for customers in these homes and are working with Sava to help achieve these objectives.

What did Cottsway want to achieve?
At the beginning of the project Cottsway held only enough energy data to calculate ratings within Sava Intelligent Energy for a small number of properties. Cottsway had commissioned a large number of EPCs over several years which they no longer had access to. Cottsway also held a lot of useful energy data in separate asset datasets such as PV information and gas boiler makes and models.


With over 80,000 units manufactured and sold in the UK since 2013, Radfan enables residents to feel warmer more quickly, potentially saving energy costs.

By circulating air within the rooms where they are situated also helps dispel the conditions which promote mould growth. 


Designed to prevent the need for the installation of both a tundish and a dry trap, whilst still preventing smells and odours passing through.

Altecnic, the leading supplier of hydronic solutions and part of the Caleffi Group, have launched a new Dry Trap Tundish. Unlike any other tundish on the market, the Altecnic Dry Trap Tundish boasts a patented, anti-splash design with a transparent chamber that provides a visual indicator for discharge and is fully compliant with G3 building regulations.  


Leading British ventilation manufacturer, Vent-Axia, will showcase its latest continuous ventilation solutions at this year’s InstallerSHOW at the NEC, Birmingham (27-29 June 2023). Located in the BEAMA1 Village, visitors to Vent-Axia’s stand will be able to discover simple solutions designed to remove the risk to installers when retrofitting ventilation by ensuring compliance with the latest Part F (Means of Ventilation) of the Building Regulations. On show will be a range of continuous ventilation including Vent-Axia’s app-controlled Lo-Carbon Svara, its highly efficient Lo-Carbon NBR dMEV C, and the Vent-Axia PureAir Sense with odour sense technology.

fuel poverty

Paul Taylor, Head of Renewables for Panasonic UK discusses how social housing providers can help tackle fuel poverty at the root, using heat pumps to provide more energy efficient homes.

The government’s recent release of new research exploring the challenges faced by fuel-poor households in winter 2022/23, has brought renewed focus to the conversation on tackling fuel poverty. It is in no doubt that Housing Associations want to do all they can to help mitigate the impact of rising energy prices on tenants and leaseholders. However, with gas supplies continuing to be disrupted by the impact of the war in Ukraine, there is a need to seriously invest in energy efficient alternative technologies to the gas boiler, to support those who cannot afford the rise in energy bills.
