    Wilo
    While fitting high-efficiency circulating pumps is now mandatory, Gary Wheatley, Wilo UK’s Training and Technical Manager, believes that there is a huge opportunity around the replacement of existing inefficient models.
  • Underfloor heating versus radiators
    Warmafloor
    Radiators Radiators distribute heat by convection currents which can result in draughts and hot spots. The floor will be coldest zone of the room as hot air rises, whilst the space above your head will be the warmest part.
  • Installing wet underfloor heating: an introduction
    Warmafloor
    How do I operate the system? By a room thermostat in each room. How is the pipe attached to the floor? - A popular system is where pipe is held in position with clips through the insulation. - A wire grid system is available...
  • AEL cast iron radiators – FAQ
    AEL Heating Solutions Ltd
    Q What are the advantages of using cast iron radiators? A Cast Iron radiators retain their heat and therefore emit heat for longer periods into your room unlike a modern pressed steel radiator. Cast iron radiators are also...
  • 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...
  • Rainwater harvesting – simply common sense
    Wilo
    Gary Wheatley, Training and 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...
  • Heat pumps and underfloor heating
    Warmafloor
    Heat pumps are now widely used in preference to boilers, and can work ideally with underfloor heating. However, they are not suitable for all applications and the following guidance is provided for application and...
  • Building Management Systems and energy efficiency

  • Carpets, underlays and underfloor heating
    Warmafloor
    Carpets and underlays have thermal resistance characteristics that will reduce the heat output when fitted over an underfloor heating system. The thermal resistance of a specific type of carpet or underlay is indicated by...
  • Screeds over underfloor heating
    Warmafloor
    Except for buildings where the concrete slab is left exposed, such as a warehouse, all concrete floors are covered with a screed layer which provides a final level finish onto which is installed the floorcovering. When...
  • 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...
  • 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...
  • 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...
  • 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,...
