Customer Brief:
In January 2024, Warmco were asked to install five Powrmatic natural gas fired, warm air, cabinet heaters and 21 de-stratification fans into three, large steel processing and steel-holding workshops in Cheshire. This customer occupied three workshop areas, which were heated by older, floor-standing warm air heaters and they wanted to update them by installing more efficient, cost-effective heating into the spaces. They wanted us to design a heating system which would take the chill out of the air in the space, with the capacity to heat the space to 13c, when it is -3c outside. The primary purpose was to prevent condensation forming on their coils of steel though it was also to raise the temperatures for the staff slightly.
Features of the Heating System:
Into the largest, 31,000 sq ft area we installed two CX300 Powrmatic cabinet heaters. The CX300 heater has a maximum heat output of 298kw, which can be used to get the area up to temperature. However, once this has been achieved, it has the capacity to modulate its heat output down to 99kw. This modulation feature offers a typical fuel cost saving of up to 30% against standard non-modulating models of heater. We also put two more CX300s into a second workshop of 26,000sq ft and a CPX200 into the final 9,000sq ft workshop (which can modulate from 200 kw down to 140 on low fire). As these buildings were 12m high, we were also asked to install 21 CECx Calecon de-stratification fans, which together could be used to redistribute 11,040m3/hr of warm air per hour, which would otherwise gather in the upper reaches of the building. Typically, the addition of fans can also also offer the end user a fuel cost saving of around 25% to 30%; a huge potential saving in spaces of this volume. The heaters also have four adjustable air distribution nozzle heads, so that the warm air emitted can be directed into different areas. Due to the increased energy efficiency and the reduced NOX levels, the heaters installed are fully compliant with the latest ErP regulations EU 2015/1188, Directive 2009/125/EC – LOT 21 Tier 1.
This project was completed in two weeks, during which time our engineers worked to create minimal disruption to our valued customer. As these were high buildings with fragile roofs, we worked with a specialist rope access company to ensure the safety of our roofing contractors as they fitted the flues on the roof. As is standard, we gave a one-year labour and two years’ parts warranty on the completed heating system.
