  • 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...
  • 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...
  • How to calculate the "delta T" for a radiator
    AEL Heating Solutions Ltd
    After you have worked out the heat requirement for your room (AEL's easy-to-use BTU calculator will help you do this), how can you check that the radiator you have chosen will provide enough heat output? There is a simple...
  • Five biggest challenges for HVAC in large open spaces
    Reznor
    Business owners and facilities managers want to improve their employee’s environment whilst managing the running costs and their carbon footprint. These factors are important when selecting HVAC equipment for premises,...
  • 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,...
  • 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...
  • Heating outputs: what is a BTU and what is a watt?
    AEL Heating Solutions Ltd
    When discussing the heat output required for a room, It can be confusing when one engineer works with BTU’s and another works with watts. So what is a BTU and what is a watt? BTU and watt are both used to measure the heating...
