Modern efficiency meets heritage at Corpus Christi College with
Hamworthy Heating H
amworthy Heating has supplied its Modumax mk3 modular condensing boilers and Powerstock calorifiers to Corpus Christi College, University of Cambridge. Installed within a Grade I Listed building; the new system delivers an efficient heating and hot water solution tailored to the unique challenges of the site. The project involved replacing an ageing plant room in the basement of the college, where access was severely restricted and space limited. These constraints ruled out traditional large-scale plant equipment and required a compact system that could be transported through narrow doorways without structural alterations.
The chosen system features four Modumax mk3 floor-standing condensing boilers (196 / 392V) delivering 1,532 kW total across eight modules. These are integrated with two Hamworthy Heating Powerstock PS500 indirect calorifiers to provide domestic hot water for the college.
The Modumax mk3 range is designed with retrofit projects in mind. The modular format allows boilers to be dismantled and manoeuvred into confined spaces before being reassembled in position, providing the flexibility needed for heritage environments where plantroom layout and access present unique challenges. By combining the modular boilers with Powerstock calorifiers, the system delivers efficient heating and a reliable domestic hot water supply for the college. To ensure precision, the project team used Hamworthy’s 3D digital design tools to plan the plant room layout in detail. This enabled much of the pipework to be prefabricated offsite streamlining installation, and ensuring new equipment could be delivered in stages. Visit

Nuaire switches to 100% recycled plastic in Drimaster-Eco Positive Input Ventilation (PIV) systems
T
he UK’s first Positive Input Ventilation (PIV) system, the Drimaster from Nuaire, has evolved once more! As from October 2025, the Drimaster-Eco has swapped its casing from a virgin ABS plastic to a recycled plastic. The switch will result in a reduction of 167 tons of equivalent embodied carbon over the period of a year.
PIV technology was invented by Nuaire in 1972 and was recognised
as a groundbreaking, highly effective cure for condensation dampness and its associated problems – including harmful black mould - within residential properties. PIV systems draw fresh air present in the loft space, filter that air, then gently disperse it into the home via a central diffuser at a continuous rate. This creates a positive pressure within the home that forces stale, damp air and pollutants out through the natural leakage gaps found in every UK property, both old and new. Tried and tested, Drimaster PIV units are installed in over a million homes in the UK and are particularly popular with social housing providers due to their cost-effectiveness, speedy install (Drimaster-Eco can be installed in a loft in less than an hour), longevity (many Nuaire Drimaster PIVs have been in operation for over 20 years), and non- disruptive nature for residents.
Moving from the virgin ABS plastic to 100% recycled plastic will not impact the quality of the Nuaire Drimaster-Eco PIV units, although customers will notice a change in colour from the blue plastic to black.

WilSon Energy launches new range of HIUs
I
ntegrated heating, metering, pre-payment and billing & bureau specialist WilSon Energy has launched its own range of Heat Interface Units (HIUs), suitable for any heat network in residential homes and commercial developments. After several months working with Europe’s leading heating engineering groups, WilSon has developed a high quality, low maintenance range of HIUs for the UK market offering a versatile, cost effective and energy efficient solution. The WilSon HIU W1 to W6 deliver a range of electric twin plate, single plate, mechanical twin plate and hybrid HIU options, ideal for heat pump applications and suitable for new build or refurbishment projects, as well as heat network upgrades.
Andy Wilkinson, CEO at WilSon Energy, said: “Designed by experienced engineers with simplicity of installation and servicing in mind, WilSon’s new range of HIUs are easy to install and configure. They can connect to any type of meter through a MBus or Modbus open communication connection, providing easy access to data for meter readings, remote diagnostics and data analytics. Following BESA testing, we’re also really pleased that the units offer the highest energy efficiency performance in the market by VWART (Volume Weighted Average Return Temperature). “Remote access to the unit via the cloud means that heat network performance and efficiency can be monitored and managed off-site with the delivery of real time information. The HIUs can be set up to bring back 45 parameters for data analysis and troubleshooting. All settings can also be securely adjusted remotely.”

ACV UK expands CIBSE-approved CPD portfolio with new module on commercial DHW systems
A
CV UK has expanded its CIBSE-approved CPD portfolio with the launch of a new module: “What You Need to Know – Commercial DHW Systems Now and for the Future”. Designed for building services professionals, the new CPD helps consultants, specifiers and contractors navigate the fast-moving landscape of domestic hot water (DHW) system design in commercial buildings.
With the need to comply with updated regulations and improve system efficiency, the new CPD explores how market demands are shifting and what that means for modern DHW system specification. It also covers key drivers such as changes to Part L, the expanding range of available technologies and how to approach system design in a way that balances carbon reduction, reliability and cost. Participants will also gain insights into demand profiling, system sizing, hybrid strategies and practical considerations such as site constraints and long-term operational performance. Designed for professionals involved in new build projects, plant room upgrades, or refurbishment work, the session provides a clear, practical overview of both the challenges and opportunities shaping the future of commercial DHW. To suit busy working schedules, the CPD lasts 45–60 minutes and can be delivered in person, online, or at ACV’s Expert Academy Training Centres.
