technologies, Go Geothermal Ltd. specified 18 Low-H2O Jaga Strada DBE radiators throughout the home, which were installed, along with the heat pump itself, by Trimark Future Energy Systems. Sean Sowden, property owner and
co-founder of Go Geothermal Ltd. outlined how his ambition of renewable energy refurbishment translated into the practical heating of the property. He said: “Minstrel’s Barn was previously fuelled through oil, which is extremely expensive and inefficient in large indoor spaces, such as the barn. “We decided to install a ground source heat pump as an alternative, supported by the use of solar thermal energy (to heat Domestic Hot Water and to pre-heat the Glycol up to 20O
C),
and set ourselves the target of achieving the most efficient closed loop ground source heat pump in the UK. With a coefficient performance (COP) ratio of at least 6.5, which has been achieved by enhancing the brine temperature from solar integration.” Jaga’s Low H2O radiators have been tested by BRE in the UK and validated again by KIWA in the Netherlands as one of the most economical in the world. The radiators require just a tenth of the water of a standard steel panelled equivalent, which means they can generate savings of between 5 and 16 per cent, compared to standard steel-panel radiators as they have less water to heat. They can quickly and efficiently heat a room, even when connected to environmentally-friendly or low water temperature heating systems, which provide a viable alternative to expensive and less responsive underfloor heating systems. Mr Sowden continues: “Given the heritage of the building, we had to ensure we retained its character. As such, we needed a heating solution that could work effectively with a heat
aldwell’s Minstrels Barn, a traditional barn in North Yorkshire, underwent a major refurbishment to convert it to a
pump whilst accommodating the building’s defining features. For example, keeping the original oak floor in some rooms, as well as decorative floor tiling in others, meant that underfloor heating wasn’t an option. Energy efficient radiators became the natural choice. “My work with Go Geothermal Ltd. means that I have come across Jaga radiators before
and I was familiar with what they are capable of, particularly with regards to their effectiveness with low temperature systems such as a heat pump.” The temperature of the water being
circulated around the house had previously averaged at 65O
C to 38 O C, with the introduction of the
ground source heat pump the water generally circulates at between 30O can reach as high as 49O
C, though it C if required. For most
radiators, achieving adequate levels of comfort from such temperatures would be a real challenge, particularly given the large spaces within the property that needed to be heated. Designed to be entirely compatible with low
temperatures, the Dynamic Boost Effect (DBE) technology works through the use of small, quiet fans attached to the heat exchangers that draw air over the element to boost the Low-H2O radiator’s output by three times. As a result, the output, efficiency and responsiveness of the radiators are improved, and an extra boost of heat can be initiated as and when required. Research published last year by the UK
Energy Research Centre and University of Sussex Centre on Innovation and Energy Demand
found that energy efficient improvements to home heating, insulation, lighting and appliances could reduce the energy consumed in UK households each year by a quarter, and knock £270 off the average annual bill of £1,100. What’s more, such investment could also deliver a net benefit to the UK economy of £7.5 billion. Therefore, it’s crucial for developers to consider energy efficient heating products when refurbishing existing homes and building new ones. Mr Sowden added: “Since the Jaga radiators
have been installed, our energy bills have fallen significantly, and the house is lovely and warm 24/7. I really like the responsiveness of the radiators, which also turn off as soon as the desired temperature is reached so that there is no wasted heat. Furthermore, the low surface temperatures of the Strada’s casing make them entirely safe for the home scenario. “Jaga themselves were supportive through- out the entire project. They were able to visit the site for measurements and recommendations, and subsequently provide us with 18 Strada DBE radiators with different specifications in terms of height, length and output. Ultimately, we couldn’t be happier with the end result.” Working in conjunction with Trimark Future
Energy Systems Ltd., who designed and installed the system, both Jaga and Go Geothermal Ltd. have contributed towards realising a forward-thinking project based on tried and tested technologies that will future proof the building’s heating system for years to come.
