  • Specifying a low level services strategy
    AET Flexible Space
    Plenum air conditioning systems offer an array of benefits compared with high level services “If it is this good, why isn’t it used more often?” Words often iterated by those learning about underfloor air conditioning for...
  • Single or two pipe central heating system
    AEL Heating Solutions Ltd
    Single pipe central heating system A single pipe central heating system operates through a main single feed hot water supply pipe which comes from the boiler supplying hot water to each radiator. Each radiator has a smaller...
  • Rainwater harvesting – simply common sense
    Wilo
    Gary Wheatley, Training & Technical Manager at Wilo UK, explains what rainwater harvesting is and why implementing it for water reuse makes sense from a financial and ecological point of view. He also gives design guidelines...
  • Solar thermal water heating in the leisure sector
    Stokvis Energy Systems
    The Carbon Trust: "Solar water heating can be very effective for swimming pools and is relatively easy to connect to a conventional heating system." Energy costs in a typical sports centre are second only to labour,...
  • The advantages of using a plate heat exchanger
    AEL Heating Solutions Ltd
    Plate Heat Exchangers are used to either heat up or cool down many different types of fluid. When heating up a fluid such as water the Primary heat source from a boiler or waste water heat recovery system will transfer the...
  • Trench Heating Frequently Asked Questions
    AEL Heating Solutions Ltd
    What is the recommended distance away from a floor level full fronted window that a trench heater should be installed? The recommended distance between an AEL trench heater and a full faced window is usually between 20cm to...
  • How to improve commercial boiler efficiency
    Stokvis Energy Systems
    Within the commercial market today, approximately 70% of boilers with outputs of 30kW and above are wall-hung. Whether these modern condensing boilers actually deliver higher efficiencies than their old counterparts is...
  • Reducing heating / cooling pump consumption by over 50%
    Frese
    The pumps installed in all newer heating and cooling systems are almost always frequency-controlled pumps, which are self-adjusting and regulate according to load. To exploit the pump optimally, it must be set and controlled...
  • What are 'Shell and Tube' heat exchangers
    AEL Heating Solutions Ltd
    Shell and tube heat exchangers are considered one of the most effective types of heat exchanger available in the UK. A shell and tube heat exchanger has a cylindrical shell with a tube bundle in the centre. The high...
  • Specifying NSHEVs for smoke and heat exhaust ventilation
    Bilco UK
    NSHEVs are installed in the roof to provide essential ventilation in the event of a building fire. They open, either by sensors or remote control, to exhaust smoke and noxious fumes. It is a simple concept, utilising simple...
  • Plate heat exchangers for commercial applications
    Stokvis Energy Systems
    A hot water system using a plate heat exchanger (PHE) heats water instantaneously and only when required, making it intrinsically energy-efficient. Calorifiers and direct-fired water heaters are less reliable and can empty...
  • Principles for maximising modern boiler efficiencies
    Stokvis Energy Systems
    What are the options for improving boiler efficiency in new and refurbishment situations? The extent modern condensing boilers actually deliver higher efficiencies compared to their old counterparts depends on a number of...
  • Plate heat exchangers uses in renewable energy schemes
    Stokvis Energy Systems
    Renewable heat sources are increasingly seen as both sustainable and economically attractive by policy makers. High performance plate heat exchangers are ideally suited for a range of applications within renewable energy...
  • What is 'Delta P' in a heating system
    AEL Heating Solutions Ltd
    The Delta P is the pressure drop in a heating system which can be defined as the difference in total pressure between two points (e.g A and B) of a fluid carried through the pipework or heating equipment such as a radiator...
  • Technological advances in boiler manufacturing
    Stokvis Energy Systems
    Technological advances have increased the efficiency of commercial boilers to the extent that established, well-proven technology ensures high efficiency and reliable performance. However, that does not mean the industry is...
