15% and reduce the efficiency of a boiler by 3%. Black iron oxide sludge or magnetite contributes around 95% of system debris and is the number one cause of heating system problems by a significant margin. The prevention and removal of magnetite is one of the most efficient methods of delivering energy efficiency and chemical treatment specialists such as Adey are responsible for technologies which achieve the best results. Chemicals, system cleaners and inhibitors have been used extensively for
half a century, yet investment in chemical innovation in the last decade has stagnated. In a recent survey of installers commissioned by Adey, when asked if they used chemicals, 99% saying they did. However, only 21% said quality was the deciding factor when purchasing chemicals, suggesting that chemical water treatment is underperforming and only offering homeowners a ‘fit and forget’ solution.
Solving homeowner problems C
hemical treatments are critical to maintaining optimum central heating system efficiency and there are a number of innovations on the market which offer a solution.
In systems of all shapes and sizes, corrosion occurs as the water and
oxygen reacts with the metal pipework as it flows around the system, leaving a residue of thick, black magnetite sludge. Left unchecked, this can cause many issues from blocked or noisy radiators and pipework, to bacterial growth, poor circulation and heat transfer. In homes, these damaging deposits can reduce heat transfer by as much as
From Adey’s point of view, its most recent innovations include an advanced range of high performance chemicals designed to transform heating system cleaning, maintenance and protection. These are said to help installers take a more proactive approach to dosing. Exclusive to professional installers, the MC and MC+ chemicals are said to provide a solution to the day-to-day problems faced by installers. Working with its MagnaClean filters, the chemicals are said to provide an
integrated protection and improved performance over the lifetime of the system. The company has developed and tested an extensive range of chemical innovations at its UKAS accredited state-of-the-art laboratory which is dedicated to ongoing product development, investigating and delivering advances in chemical performance, and is home to the water testing service Adey provides for customers.

Heat loss calculators get radiator sizing right
telrad Radiators, the radiator manufacturer, has launched two new improved advanced heatloss calculator programmes.
It’s an online tool that has been used for years
by dedicated heating system designers and heating engineers. The very latest versions – one a comprehensive version, the other a simpler more basic one – offer a free and simpler way to get sizing of radiators right, first time. 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 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. To do a professional job, it 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. The new systems feel much more like a standalone application than a web page although they are still run in a web browser. 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. Interaction feels faster than the old system and smoother too, due to the single page interface. Data can be cached locally,
removing the requirement for the user to be continually online while using the application. There’s a new Room Planner with the new
system. It offers more accurate positioning and sizing of walls and surfaces. The interface for selecting wall, floor and ceiling types is simplified, as is the interface for specifying doors and windows.
The latest versions are available for download
from the Stelrad website, where installers can also see the full range of Stelrad radiators including the new ranges added to the system. The heat loss calculators are one-stop shops for choosing the right radiator product for the right project and help in accurately sizing radiators for a heating system. They are aimed at all Stelrad users, from one off self-builders and home renovators, to architects and specifiers, and housing developers. They’re available as downloads only via
www.stelrad.com Installers can click on Heat Loss Calculators, and follow the instructions.
