  • 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 dependent on four key factors....

  • 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 hot water supply pipe branched off the main feed pipe to supply the radiator. The water passes through the radiator coming...

  • Why use Linear Drainage?
    Component Developments
    Functional Advantages: channels are a hygienic and efficient way of conveying waste water from equipment discharge and floor washing; water is efficiently disposed of at the source, rather than flowing across the floor to a spot gully subsequently causing a slip hazard; simple to install; large reservoir capacity; channel systems can be utilised...

  • Timber floors and underfloor heating
    Underfloor heating can be installed with most types of timber floors quite effectively. Care must be taken however in the design of the system and the flooring materials used to ensure a trouble-free system. Heat output The heat output from a timber floor system is limited by the timber floor itself. As timber is an insulant, it restricts the...

  • Underfloor heating versus radiators
    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...

  • Heat pumps and underfloor heating
    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 installation. Suitability Lower energy use in buildings relies mainly on the building being constructed with high levels of insulation...

  • 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...

  • 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"...

  • Prevention of explosions when boiler house fires occur
    Introduction The most common fuels in use for space and water heating are oil, natural gas and liquid petroleum gas (LPG). By far the most popular, clean and cost-effective solutions are natural gas or LPG. The traditional safety measure derived from the time of oil-fired boiler houses is the use of a fusible link placed above the each boiler. The...

  • Reducing heating / cooling pump consumption by over 50%
    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...

  • Fight against plagiarism: protecting the future
    Counterfeit products can cause significant damage, not to mention the non-quantifiable reputation damage suffered by manufacturers as a result of products that are often of low quality. The best way to deal with this is to use property rights, such as the patent, and to use correct, reliable sales channels. Making solutions exclusive and...

    Component Developments
    LEISURE AND SPORT Contract award levels were 13.4% lower than May, and 0.5% lower than June 2016. In the three months to June the value of contracts was £1.3billion, which was 42.6% lower than the previous three months. This was an increase of 20.9% compared to the same period in 2016 indicating that while there have been recent falls there is...

  • Expansion joints and underfloor heating
    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...

  • Carpets, underlays and underfloor heating
    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 its tog rating (1 tog being equivalent to 0.1W/m2K. The higher the tog value the better insulator it is. So the lower the tog...
