Modern Efficiency Meets Heritage at Corpus Christi College with Hamworthy Heating

 

Hamworthy Heating, a trusted British manufacturer and supplier of commercial heating and hot water products, 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.

 

Hamworthy Heating’s Modumax mk3 range is specifically 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 both 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 approach enabled much of the pipework to be prefabricated offsite, which streamlined the installation, and ensured that new equipment could be delivered in stages and installed in a single operation.

 

“The 3D models allowed us to coordinate the plant room before we even stepped on site. It saved time and helped everything run efficiently. Careful delivery planning also meant the installation could be completed in one single day,” explains Geoff Bunton of Bunton M&E Services.

 

The completed upgrade now provides Corpus Christi College with a robust, futureproof heating and hot water system that improves efficiency, reduces emissions, and meets the demands of its academic community, all while preserving the integrity of its historic setting.

Rinnai is continuously expanding and updating its entire product offering to include all fuels and appliances for installation as stand-alone units or as part of hybrid systems for larger commercial sites.

Rinnai’s extensive product range now includes a wide selection of electric technologies. Rinnai’s Infinit-E range is an optional three-phase all-electric water storage heater for commercial hot water applications. All Rinnai electric storage hot water heaters are designed with flexibility in mind.

All units are fitted with between one and six titanium elements. The KW rating  of the Infinit-E range is scalable from 12kw to 72kw ensuring that all units are suitable for a wide variety of applications. All electrical elements can be fitted to a single-phase supply, should site limitations dictate. Each element within the appliance range has its own controllable thermostat with a temperature range of between 49 and 90 degrees Celsius. All elements are fuse protected and there is no need for expensive sacrificial anodes due to a tough stainless-steel build.

Each cylinder is manufactured with stainless steel adding durability and enabling extensive warranties. The use of stainless steel also makes the Infinit-E range lightweight and easily manoeuvrable and handled when compared to glass-lined variants. The empty weight of the Infinit-E is 54kg maximum.

All-electric systems can benefit from Rinnai’s modulating smart electric cylinder range – ensuring that the only direct electricity used is to fill the performance gap from a renewable heat source.

Rinnai’s range of electric products also include monobloc air source heat pumps that are available in an assortment of variants, from 4kW to 110kW. Rinnai’s heat pump technology ensures that up to and including seven units can be cascaded together.

A cascaded system means that multiple heat pumps can work in conjunction allowing for a level of functioning synchronicity that produces greater operational performance for larger commercial applications.

All Rinnai commercial heat pumps use LOW-GWP including R32 and R290, renowned for reducing electricity consumption by up to 10% and for holding a lower global warming potential (GWP). Rinnai’s HPI heat pump range is ratified with an ERP rating of A +++ and includes an operational ability to switch between settings of heating, hot water, and cooling.

Rinnai’s HPI air source heat pumps, hybrid formations, electrical formats and hydrogen gas mix powered water heaters are part of the H3 range of products. All new models are designed to embolden decarbonisation, energy efficiency and reduce customer costs by offering practical, economic and technically feasible solutions to all UK customers.

Rinnai is now offering a NEW and FREE customer service that designs the ideal heating and hot water system suited specifically to the customer’s property requirements. A hot water and heating system designed to the specific needs of any site or application ensures that savings can be made in purchase and running costs, as well reducing carbon emissions.

Some properties are better suited towards a specific heating and hot water delivery system. For example, hybrid heat pump or solar thermal with BioLPG options could be considered the better solution for heating and hot water delivery when thinking of off-grid rural locations especially those with high demand for heating and hot water – hotels, residential care homes, health centres etc.

Inner-city occupants could be advised to look at utilising either hybrid designs, including hydrogen-ready units for gas blends of up to 20% along with products and systems of technical and practical feasibility.

If say, a customer owns an urban retirement community consisting of three Edwardian houses with a mixture of heating and hot water delivery applications, Rinnai can design and install ONE WHOLE system that guarantees maximum output and minimises fuel and operational costs whilst considering the feasibility of the solution from the perspective of the building and budget.

Not only will Rinnai advise the customer on what system should be installed, Rinnai will design a heating and hot water system that complements the customer’s site, uniquely. Whichever location or dwelling, Rinnai can offer and design a heating and hot water system that will help reduce costs and carbon emissions.

Adds operations director of Rinnai Mr Goggin:

“We have positioned the Rinnai name as a company that offers the highest quality product and best available value with service excellence. It is a position of responsibility and we have maintained a stance of doing the absolute best we can for customers. We believe implicitly in this basic premise – we do the best we can, and we achieve what our customers want and expect. And that includes anticipating the future. We are manufacturers of proven excellence and are using our core competencies of design engineering solutions to suit all possible future needs and fuels.”

Rinnai offers a range of decarbonising and cost reducing energy options applicable to all types of properties. Heat pump, BioLPG, solar and hydrogen can fulfil all domestic and commercial energy demands.

Rinnai’s new heating and hot water delivery design service is an integral part of Rinnai’s H3 range of products.
