  • 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 resting on its laurels, because new developments continue to boost the energy efficiency and overall effectiveness of heating...

  • Expansion joints and underfloor heating
    Warmafloor
    Expansion joints and crack inducers All screeds expand and contract to some degree so allowance has to be made for this. The perimeter insulation fitted with underfloor heating allows for some of this, however large areas will need to have expansion joints or crack inducer cuts in the screed itself to allow movement and avoid screed cracking...

  • 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 of hot water when higher than normal demands occur. Plate heat exchangers are easy to maintain and present no risk of bacterial contamination of the water....

  • 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 underfloor heating is installed, perimeter wall insulation and floor insulation panels with a fitted moisture barrier are...

  • 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, accounting for as much as 30% of total running costs....

  • Five benefits of switching to EC fans in HVAC equipment
    Airedale International Air Conditioning
    For many businesses, a 20% reduction in energy costs represents the same bottom line benefit as a 5% increase in sales (The Carbon Trust). However, reducing energy consumption in a building, on an ever decreasing budget, is one of the biggest challenges for facility and energy managers...

  • 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 where pipework is held in place by cable ties affixed to the wire mesh. - For joisted or batten floors a clip rail system is...

  • 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. Radiators transfer heat into a room largely by convection from a hot metal surface. Because the surface of the radiator 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 correctly. When you use any Frese dynamic valve, you avoid overflow and the pump has to handle no more than the volume of...

  • 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 aesthetically more pleasing to look at than a steel panel radiator. Q I have standard pressed steel radiators, can I replace...

  • 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 calculation to check if the radiator will provide sufficient heat output. You must check the “delta T”. What is the "delta T"...
