STELRAD SEES SUCCESS FOR ‘GREEN COMPACT’ RADIATOR SERIES
L
eading radiator manufacturer Stelrad Radiators continues to offer low carbon-emissions steel radiators, with an excellent response so far to this new approach to the reduction of
carbon emissions in the production of steel radiators. Stelrad customers can choose a Green Compact radiator range that contributes directly to a reduction in atmospheric CO₂ emissions today and accelerates decarbonisation in the future. The Green Compact comes with an Environmental Product Declaration (EPD). An EPD transparently reports objective, comparable and third-party verified data about products’ environmental performance over the lifecycle of the radiator. This guarantees a thorough and verifiable declaration in line with the ISO 14025 standard for environmental labels and declarations. The steel utilised in the manufacture of these Green Compact
radiators is XCarb® recycled and renewably produced steel, which is made in an electric arc furnace with high recycled content and 100% renewable electricity. Using this low- emissions steel results in a 66% reduction in CO₂ emissions per tonne of steel, compared with using the same product made via the conventional steelmaking process. Stelrad’s head of marketing Chris Harvey says: “This is proving to be an exciting step for us to take.
Continuing our move towards greener manufacturing and providing better information through the Green Compact EPD fits in perfectly with our Group’s sustainability policy. The Stelrad Green Series comprises of 60 horizontal models from our Green Compact range. The concept is already being well received by many of our customers who are keen to see more sustainable products being utilised in their homes and buildings. As well as the reduction in carbon emissions, no plastic will be used for the outer packaging either, further increasing the sustainability of the product range – and of course, a radiator is 100% recyclable.” Each radiator in the range will continue to bear a ‘Green Series’ radiator badge distinguishing them
from the standard ranges and come with a green packaging label as well to make them stand out from the crowd. “We’ll be rolling the new series out from April 2025 onwards” comments Chris Harvey. “This is an important confirmatory step for us to provide products that use materials with significantly lower carbon emissions and that support the decarbonisation of steel and our partners ArcelorMittal, who are working with market leaders across a variety of industries, to supply decarbonised steel products. We believe that many of our customers are seeking ways of reducing their impact on the environment and will welcome these low carbon-emissions radiators and incorporate them into their projects in the months and years ahead. The EPD is available via our website at
www.stelrad.com.” To find out more about this exciting new range, head for our website.

he Powersaver Dual Flexi 2 from Sangamo is an electronic immersion controller with programmable operation that is suitable for Single, Twin and Dual element immersion heaters. It bridges the gap between the bulky, aged electro-mechanical immersion controllers and the more
complicated digital versions. A table of pre-selectable adjustable programs is offered – covering all of the low rate electricity tariffs, including Economy 7, Economy 10 and Eco 20:20 times. Turn the Installer Switch to the program of choice (refer to Installation and User Instructions). Adjustment is possible to the preset times enabling the program periods to be reduced or cancelled as required. The review button allows ON/OFF times to be checked & there is automatic GMT/BST changeover. There is a ½ hour, 1 hour and 2 hour boost function with a digital display countdown clock, allowing
the user to clearly see boost times. There is also a programmable boost function for further end user convenience; this program is deliberately limited to a maximum of 2 hours, meaning expensive electricity is not being wasted during peak times. The Sangamo range of specialist time switches and heating controls is distributed through Scolmore Group company, ESP.

Grade II Listed London School Achieves Carbon Reduction Through Heat Pump Installation
T
he listed Victorian Gothic Revival ‘Riverside School’ is situated along the Thames, has successfully implemented a comprehensive decarbonisation project, featuring
the Mitsubishi Electric 2*40kW CAHV and a 40kW QAHV heat pump units connected to K-con thermal and potable water vessels. This school has recently been fully refurbished and extended; and underscores the feasibility of integrating sustainable heating solutions within historic buildings. HOB Mechanical Services the mechanical services contract, necessitated the design and installation of a pre-specified Mitsubishi Electric heat pump system. The project presented two primary challenges: space constraints within the designated plant room and to mitigate noise in a densely populated residential area.
Innovative Engineering Solutions: In collaboration with Kooltech, HOB Mechanical Services engineered a bespoke solution to address these challenges. Kooltech's expertise facilitated the integration of their K-con product range, specifically tailored thermal storage vessels. Two custom-fabricated, stainless steel cladded vessels were externally situated freeing up valuable internal plant room space that houses the installation of two 255L stainless domestic hot water cylinders connected to the QAHV heat pump units. To mitigate noise pollution, acoustic enclosures were incorporated into the design, achieving an additional 8dBA reduction from the CAHV air source heat pump units utilised for space heating. This, coupled with the CAHV units' integrated noise reduction capabilities, ensured minimal disruption to the surrounding community. Luke Edwards, Contracts Manager at HOB Mechanical Services, said “Working with Kooltech meant
that we found a solution to meet the stringent needs for this project. They designed the vessels to purposely meet our space issue requirements. This is one of the first projects that we’ve worked with Kooltech directly on, and the ease and speed of service was second to none, we look forward to working with them on future projects as we know that if they do not have an off-the-shelf solution, they are able to customise their K-con products to suit.” Ben Hancock, Head of Southern Sales at Kooltech, added, “With the support of our engineering and K-con
R&D team and our exclusive partnership with Mitsubishi Electric we were able to apply our expertise in the complete system design and integrating components to help deliver the projects tight requirements and create a lasting positive impact with the school and working with H O B Mechanical Services.” The project culminated in the successful installation of a high-efficiency heating and hot water
decarbonisation system, adhering to stringent noise reduction parameters. This project shows how the implementation of sustainable heating solutions in heritage buildings, working together with engineers and suppliers achieves great results.
