  • 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...
  • Why district heating for communal housing is on the rise
    Stokvis Energy Systems
    Properly specified district communal schemes in blocks of flats or across larger developments can provide energy efficiencies and are simpler to administer than unit based approaches. This article explores right sizing,...
  • 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...
  • 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...
  • 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...
  • 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...
  • 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...
  • Increasing heating efficiency with plate heat exchangers
    Stokvis Energy Systems
    How using modern modulating low water content gas boilers in combination with compact modulating low water content plate heat exchangers can meet hot water demand reliably, safely and economically, whatever the type of...
  • 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...
  • 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...
  • 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...
  • 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...
  • 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...
  • 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,...
  • 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...
