The Vaillant 0020143502 Sensor is a genuine replacement component designed to monitor temperature within the boiler’s heat exchanger or water circuits. By providing accurate readings to the boiler’s control system, it enables efficient operation, optimal fuel use, and safe temperature regulation. A malfunctioning or worn sensor can lead to erratic heating, repeated error codes, inefficient energy use, or boiler lockouts. Manufactured to strict Vaillant specifications, the 0020143502 Sensor is built for durability under high-temperature, high-pressure conditions, and repeated thermal cycling. Installation restores accurate system monitoring, ensuring that the boiler responds correctly to heating demand and maintains safe operation. Professional installation by a qualified engineer is recommended. The sensor should be positioned exactly as specified in the boiler’s design, connections secured, and the system tested for correct readings and operational efficiency.
Vaillant provide a 1 year warranty on all genuine spare parts. Electrical Deals Direct now sells a wide range of spare parts. If you cannot see the item you require on our website, please call 01934 253600 or email [email protected] for more information.

Standard delivery for all orders over £150 ex-VAT are free of charge.
If we can speed this up, we will, but you can also select Express Delivery when you check out and get your purchase more quickly (usually the next working day, subject to a 1pm cut-off): there is an extra charge for this ranging from £5 to £29.99 depending on the products you are buying.
We partner with several of the best UK carriers (such as TNT, Royal Mail, DPD etc) depending on the type of product and the warehouse it is coming from, and also with some pallet companies for larger items. All of these operate during normal Monday – Friday working hours, and we expect all deliveries to arrive in 5 days. For more details checkout this page.
For all Gledhill Cylinders, a flat delivery charge of £27.50 (ex-VAT) applies, regardless of order value or delivery method. This will be added automatically at checkout.
Having to return a product because it doesn’t fit, or is not what you wanted, is really annoying! To try and make sure this isn’t necessary we have lots of helpful advice on our site, and you should feel free to call our experts on the number above to check if you are in any doubt at all – we’re always happy to help.
But if you do, don’t worry, just contact us and we’ll get it sorted (note that for trade customers there may be a restocking fee). If you need it, we can usually arrange the carrier to pick it up.
