Stage 1 Take the room dimensions in metres Width m Length m calculate the volume (W x L x H) = Height m cubic metres Stage 2 Heating requirements per room type Living Room / Dining Room / Bathroom multiply volume as calculated in Stage 1 by 50 = Bedroom Watts required volume multiply volume as calculated in Stage 1 by 40 = Kitchen / Hallway volume Watts required volume multiply volume as calculated in Stage 1 by 30 = Why is it important with some of the models that the flow is in a specific connection position? Some of the design radiators have baffles inside the water-carrying tubes to divert the water flow around the whole radiator to maximize efficiency. Check the installation instructions to see if this applies to the radiator before it is installed. Watts required Stage 3 Other factors for consideration Is the property exposed? a Does the room have large areas of glazing? b Are the windows double glazed? c If factor ‘a’ applies, increase the Watts required at Stage 2 by 15% If factor ‘b’ applies, increase the Watts required at Stage 2 by 20% If factor ‘c’ applies, decrease the Watts required at Stage 2 by 10% If factor ‘a’ and ‘b’ apply, increase the Watts required at Stage 2 by 35% If factor ‘a’ and ‘c’ apply, increase the Watts required at Stage 2 by 5% If factor ‘b’ and ‘c’ apply, increase the Watts required at Stage 2 by 10% If factor ‘a’, ‘b’ and ‘c’ apply, increase the Watts required at Stage 2 by 25% Please note that this calculator is provided as a guide only. To convert Watts to BTUs, multiply by 3.412. For an approximate conversion from ΔT50°C to ΔT60°C, multiply the ΔT50°C output by 1.2. Terms and Conditions of Trading A complete copy of the company’s terms and conditions of trading are available on our website www.zehnder.co.uk In addition to the Terms and Conditions, please note the following: All delivery times quoted are estimates only. Prices quoted include free delivery to the UK mainland for radiators and towel rails. Orders for valves, fans, elements and accessories with a net order value under £100 are subject to a processing charge of £10 + VAT Returned goods for credit will only be accepted by prior arrangement (confirmed in writing), within 8 weeks of the date of despatch, where the goods are part of our stock range and where the goods are as fit for sale on their return as they were on delivery. If goods have been fitted this is deemed as acceptance of their quality. We cannot accept the return of non-stock goods. You are responsible for ensuring the suitability, conformity and interoperability of the goods or indicative system design suggestions provided by us with your heating system and your design requirements. It is important that you undertake such verification with an appropriately qualified expert third party Where a radiator is returned as no longer required and an alternative radiator is not ordered a 25% restocking fee plus a £10 administration fee will be charged (unless the goods were defective when delivered). If a radiator is no longer required but an alternative radiator is ordered, either a restocking fee of £25 or 25% of the value (whichever is the lower) will be charged, but the administration fee will be waived. We warrant the goods for a period of 5 years for steel radiators, 10 years for stainless steel and aluminium radiators, 2 years for radiator electrical componentry and 3 years for extractor fans, from the date of delivery. The warranty is subject to correct installation to current standards/water treatments and use. Radiators with steel components (other than stainless steel) must not be installed on a domestic hot water circuit. If a stainless steel or brass product is to be installed on the domestic hot water circuit, a check should be made with the local water authority to ensure that dezincification is not a common occurrence. Artificially softened water should not be used to fill radiators. For FAQ radiator/water-related information, visit www.fernox.com.

Bathroom Zones The diagram below shows a bathroom divided into four clear zones: 0, 1, 2 and outside zones. Please note, the diagram is only a guide and is NOT to scale. Please refer to I.E.E Wiring Regulations (BS 7671:2008) for detailed information. Zone 0: Inside the bath Zone 1: Area above bath / shower tray to a height of 2.25m. Minimum rating of IPX4 should be used unless water spray will be present. In this case, a rating of IPX5 should be used. Zone 2: Area stretching 0.6m from zone 1. Minimum rating of IPX4 should be used here. Outside Zones: No water spray is likely to be used here, therefore, no IP rating is required. IP Rating: “X” denotes level of security against dust particles. Second digit denotes level of “watertightness”. IPX5: Protected against low pressure water jets IPX4: Protected against splashing water 50 What is an inhibitor and why should it be used in a central heating system? An inhibitor is a chemical mix that should be added to the central heating system water to prevent corrosion and to prolong the life of the system. When new or additional radiators are being installed, the system should be drained, cleaned and flushed in accordance with BS7593 and a good quality chemical water treatment inhibitor should be added to the heating system. Can steel and aluminium radiators be put on the same system? Yes, as long as an inhibitor for mixed metal systems is used. In reality, most systems are already mixed metal, as many have aluminium heat exchangers in the boiler, plus copper pipes and steel radiators already installed. Why is it important to use dual energy installations correctly? Simultaneous use of the electrical element and the central heating system should be avoided as this will shorten the life of the element and invalidate the warranty. Correct use is as follows: In summer when the central heating is switched off, vent the radiator to ensure there is no air present, then close the flow valve (only) and activate the immersion heater. In winter, de-activate the immersion heater and open the flow valve. What is the difference between outputs listed at ΔT60°C and ΔT50°C? ΔT60°C allows for older boiler systems, whilst ΔT50°C is the new European testing standard for modern boilers, such as condensing boilers, which have lower flow and return temperatures. Therefore, to avoid radiators being incorrectly sized, it is important to know the system’s temperatures and take them into consideration. © Zehnder (retail) - A Division of Zehnder Group UK Ltd.
