HEATING ELEMENTS Here is a summary of the key differences between the stock model elements.

As Terma manufactures both elements and radiators, we electrify, and have expert knowledge in combining the two together. Here is some key advice regarding heating elements. Wattage Selection Advice To correctly choose the right wattage of element for your towel rail or radiator, you should look at the output of the chosen radiator as central heating (hydronic) in watts and choose an element with the wattage closest to that figure (+/- 100 Watts is fine). If the output of the chosen radiator is only listed in BTUs, the conversion formula is BTUS / 3.41 = Watts. Electrification Advice When making the decision to electrify any towel rail or radiator it is important to check with the manufacturer of that model that it is suitable to work with a heating element. Not all towel rails or radiators are suitable dependant on their design and how the heat will cycle internally around the rail, so avoid electrifying certain models as they won’t work and this will not be the fault of the element. Heating Medium & Air Cushion If filling a rail or radiator yourself it is best to use 85% water with 15% Euthylene Glycol (car anti freeze) (or central heating inhibitor and boiler noise silencer from a DIY store - a capful of each will suffice). The heating medium inside (the water or oil) will expand when hot, so you must ensure you leave a gap at the top of the liquid to allow for this thermal expansion, so only fill your rail or radiator to approx. 90-95% full inside. Horizontal Installation of an Element All heating element can be installed vertically in a radiator or towel rail, however when installing horizontally we advise you purchase either the KTX range (page 81) or the VEO range (page 82), as these have separate probes and you have control over the positioning. See the notes we have made about this on page 81.

Essential Maintenance of any Heating Element Installed as Dual Fuel
KTX-3*
IMPORTANT: Essential maintenance for the safe use of a Terma heating element installed as dual fuel (note: this does not apply to standalone electric towel rails). If this maintenance is not carried out, this could potentially cause the surface to get very hot and towels stored on it could catch fire. To explain: A dual fuel towel rail is not a sealed unit (like a standalone electric model), therefore as the water flows in / out from the boiler air can build up at the top over time. Therefore it is essential to regularly bleed (vent) a dual fuel towel rail to release any build of air, we suggest every 6 months or so. When the towel rail is cold – simply turn the top air vent anti clockwise to open it you’ll hear any air build up hiss and release, when see water you can close the vent. Failure to do this could mean the upper tip of your heating element probe may be heating dry, and elements must be submerged in solution (just like inside your kettle). They are safely designed cut out when used in open air - but they will when only partially in open air around the tip. So just like you would not allow fluff to build up in your tumble dryer as this could cause a fire – don’t allow air to build up at the top of your dual fuel towel rail for the very same reason. Terma supply safety stickers in our heating elements for the electrician to stick to any dual fuel towel rial advising users of this essential maintenance.

If you require models in colours other than stocked, these will be a special order on a 3 week lead time. Note: The ONE and VEO ranges can be made in any colour in single units – other elements will carry a MOQ of 100 units outside of the 4 basic colours. SIM is only available in a stainless steel head.
