On a mobile device, users can save short cuts to the heat loss calculators on their home screen making it feel even more like an app. The new systems feel much more like a standalone application than a web page although they are still run in a web browser. There’s no better way than to use Stelrad’s heat loss calculators – which have all the information embedded that allows you to do this.
#RADIATOR CALCULATION TOOL PROFESSIONAL#
To do a professional job, it clearly makes sense to use the right components and to make a few relatively quick calculations to ensure that what you recommend, delivers exactly what the customer needs in his or her home. To ensure that the maximum energy efficiency level is obtained from a heating system – and by definition, that emissions are lowered and energy costs are reduced for the householder – it’s vital that the radiators on that system are correctly sized, to reflect the size and shape of the room they’re in and to take into account the materials used in that room’s construction, in particular taking into consideration the levels of insulation that have been incorporated. Simply click on to the Stelrad web site at click on Heat Loss Programme, register – and you’re away. And what’s even better, they’re still free. The very latest versions – one a comprehensive version, the other a simpler more basic one – offer an even simpler way to get sizing of radiators right, first time. It’s an online tool that has been used for years by dedicated heating system designers and heating engineers. A combination of a larger radiator and fixing thermal board to the ceiling in the bedroom.Stelrad Radiators has launched 2 new advanced Heatloss calculator programmes, formerly known as ‘STARS’.Fixing thermal board to the internal surfaces of all walls and ceilings with no changes made to the heating radiator.A change of radiator to improve the size of the heat output with no changes made to the structure.The XCC was used to model the changes that would occur using various scenarios including: The initial preference of the local authority was to improve the thermal resistance of the bedroom walls and roof construction by fixing thermal board to the internal wall and ceiling surfaces of the bedroom. Several options for remedial action were then considered.ĭiscussions were had with the property owner whose preference was to improve the heating. The Excess Cold Calculator (XCC) was used to assess the design heat losses and confirmed that, for the bedroom in question, it would not be possible to achieve a healthy internal room temperature over the winter months. Upon first inspection there was some concern about the ability of the heating provided to adequately heat the bedroom of concern, particularly taking into account the un-typical number of heat loss surfaces overall and the thermal resistance of the flat roof given the small radiator output size. The boiler is a relatively modern noncondensing combination boiler and is in good condition. The room has a small central heating radiator as part of the heating distribution system serving the flat. It has three external, heat-loss walls but has been provided with a post-2002 double-glazed window of pvc-u construction. The bedroom of concern is located at the rear in the part of the construction under the flat roof. The first floor flat comprises of a lounge/kitchen, bathroom and two bedrooms. The roof space under the pitched roof was found to have a glass-fibre quilt of around 150mm depth. It is considered that any insulation originally provided will be fairly minimal. It does not appear that cavity wall insulation was provided and neither is there any evidence that additional insulation was provided to the flat roof. The property has since been converted into a ground and first floor flat. The original house wall construction would be un-insulated cavity walling. This extension appeared to be of un-insulated cavity wall insulation under a flat roof. The flat is on the first floor of an original end-terrace inter-war local authority house that was extended at the rear over two stories during the early 1980s. A complaint was received from a private tenant advising that his heating was insufficient to heat one bedroom in his flat and that he was suffering from significant condensation mould in the same room.
