  • 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...
  • 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...
  • What is a solar heating system 'heat dump'
    AEL Heating Solutions Ltd
    A Solar Heating System “Heat Dump” is a thermally conductive central heating heat exchanger such as a FARAL Aluminium radiator that will quickly absorb and disperse high temperature heat away from a Solar Heating System. A...
  • 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...
  • Huge opportunity replacing inefficient circulating pumps
    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.
  • 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...
  • 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...
  • The advantages of using a plate heat exchanger
    AEL Heating Solutions Ltd
    Plate Heat Exchangers are used to either heat up or cool down many different types of fluid. When heating up a fluid such as water the Primary heat source from a boiler or waste water heat recovery system will transfer the...
  • 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...
  • 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...
  • 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...
  • 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,...
  • 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...
  • Fight against plagiarism: protecting the future
    Wilo
    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...
  • 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...
