Page 4: Introduction To The Smartrad
SmartRad planning manual – Issue 1 – 15 April 2010 1 Introduction to the SmartRad The SmartRad is a stylish and modern alternative that out performs traditional radiators. At the heart of the SmartRad is a heat exchanger with a large surface area, which allows effective transfer of heat into the room even at low flow temperatures. -

SmartRad planning manual – Issue 1 – 15 April 2010 Figure 1: Radiator sizes based upon a “Double convection” design with an output of 1537W Figure 2: SmartRad size based upon fan speed 2 setting with an output of 1537W. 2.1.3 Lower Water content The SmartRad contains only a fraction of the water compared to a traditional radiator. -
Page 6: Low Surface Temperature
SmartRad planning manual – Issue 1 – 15 April 2010 With the SmartRad the lower water flow temperatures and increased mixing of the air by the fan mean that there is less temperature stratification, meaning that the average room temperature is in fact lower, meaning there is less heat loss to the ceiling and upper walls. -

Page 13: Water Connection
SmartRad planning manual – Issue 1 – 15 April 2010 5.4 Water Connection There are a number of different plumbing options which the installer can adapt depending on the project as shown in Figure 5. The inlet and outlet pipes on the heat exchanger are plain 15mm pipe. Note that on the left hand side of the product the pipes pass in front of each other but on the right hand side pass side by side as shown in Figure 6. -

SmartRad planning manual – Issue 1 – 15 April 2010 Figure 6: Note the different orientation of the flow and return pipes on the LHS and RHS. 5.5 Corrosion inhibitors The use of anticorrosion inhibitors is permitted with SmartRad. A general rule is that SmartRad system should be given the same protection as a wet radiator system. -
Page 15: Typical Applications
SmartRad planning manual – Issue 1 – 15 April 2010 6 Typical applications The SmartRad is highly versatile; it can be used in conjunction with radiators or in conjunction with under floor heating. In all cases it is important to ensure that there is always an adequate flow of hot water at the correct temperature through the SmartRad throughout the entire heating season. -
Page 16: Controls And Control Strategies
SmartRad planning manual – Issue 1 – 15 April 2010 Controls and Control strategies Figure 7: SmartRad controls 6.5 Mixed SmartRad and Radiator circuits It is permissible to place radiators and SmartRads on the same heating system however the flow rates and MWT through each product should be considered to ensure that they give the desired output. -
Page 17: Individual Smartrad Control Plug In Controllers
SmartRad planning manual – Issue 1 – 15 April 2010 This means that the entire heating system can be enabled by a central timer clock which controls a circulating pump. The added advantage of SmartRad over radiators with TRVs is that the thermal mass of the SmartRad is much lower so therefore less heat is wasted when the system is turned off. -
Page 18: Designing The System For Maximum Efficiency
SmartRad planning manual – Issue 1 – 15 April 2010 7 Designing the system for Maximum Efficiency 7.1 Choosing a Mean Water Temperature (MWT) The MWT is the average between the inlet and outlet across the radiator. Feedback from customers is that a MWT of 40⁰C gives adequate air off temperatures. - Page 19 SmartRad planning manual – Issue 1 – 15 April 2010 demand. Care should be taken when setting the weather compensation curves that the Mean Water temperature does not fall too low, so that the air off temperatures starts to feel cool. For a heat pump a lower mean system temperature gives a higher Coefficient of Performance.
