If the output of the chosen radiator is only listed in BTUs, the conversion formula is BTUS \/ 3.41 = Watts.\u003c\/li\u003e\n\u003cli class=\"whitespace-break-spaces\"\u003eElectrification 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.\u003c\/li\u003e\n\u003cli class=\"whitespace-break-spaces\"\u003eDual Fuel Advice: If you are buying a heating element to convert a towel rail for use as dual fuel (electric in the summer and central heating in the winter) it is important to remember to regularly bleed the towel rail, as on a central heating system air can build up inside. A heating element should never be run in the open air as this could potentially cause the surface of the rail to get extremely hot and burn your towels. This is just the same as you would not run a kettle dry, so remember to regularly bleed to avoid any risk.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3 class=\"tio-section-title\"\u003eWhat is a heating element?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eA heating element is used as the heat source in an electric towel rail or radiator.\u003c\/li\u003e\n\u003cli\u003eIt works by heating the water or oil inside the radiator, in the same way an element heats water inside a kettle.\u003c\/li\u003e\n\u003cli\u003eWe have a full guide on heating elements if you want to learn even more — \u003ca href=\"https:\/\/www.theheatison.uk\/pages\/technical-advice-heating-elements\"\u003eclick here to read the dedicated guide\u003c\/a\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 class=\"tio-section-title\"\u003eTemperature control \u0026amp; operation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThe Terma 43D Element is pre-programmed to run at an internal temperature of 43 °C, providing Low Surface Temperature (LST) style operation.\u003c\/li\u003e\n\u003cli\u003eDesigned for sensitive environments, ideal for hospitals, care homes, nurseries, and other areas where user safety is critical.\u003c\/li\u003e\n\u003cli\u003eTo ensure correct surface temperature, it is advised to reduce the output of your radiator (as water) by 40% when specifying this element (e.g., for a 200 W towel rail, install a 120 W element).\u003c\/li\u003e\n\u003cli\u003eNo built-in timer, but compatible with an external timer as it remembers settings when switched off.\u003c\/li\u003e\n\u003cli\u003eIncludes a 2-hour drying function for towels or laundry.\u003c\/li\u003e\n\u003cli\u003eSupplied with a 565 mm internal probe length.\u003c\/li\u003e\n\u003cli\u003e66 mm length measured from the thread down, with a 55 mm diameter clock-style face.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 class=\"tio-section-title\"\u003eElement specifics\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eStraight cable supplied, no plug.\u003c\/li\u003e\n\u003cli\u003eIPx5 rated, suitable for use in bathroom environments.\u003c\/li\u003e\n\u003cli\u003eClass 1 electrical rating.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 class=\"tio-section-title\"\u003eWattage selection advice\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eChoosing the correct wattage heating element is essential for safe and effective performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003e\u003cstrong\u003eAs listed above already - but once again as this is unique to 43D: \u003c\/strong\u003e\u003c\/em\u003eTo ensure correct surface temperature, it is advised to reduce the output of your radiator (as water) by 40% when specifying this element (e.g., for a 200 W towel rail, install a 120 W element).\u003c\/li\u003e\n\u003cli\u003eSelect an element with a wattage as close as possible to the radiator’s central heating (hydronic) output measured in watts.\u003c\/li\u003e\n\u003cli\u003eIf the output is listed only in BTUs, convert using the formula: BTUs ÷ 3.41 = Watts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 class=\"tio-section-title\"\u003eInstallation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFull installation instructions are supplied in the accompanying manual, but the following points are useful to read in advance.\u003c\/li\u003e\n\u003cli\u003eThe element must never be switched on in open air — it must be fully submerged in the heating medium to operate safely.
