Detailed information

Product detailed description

NTC Sensor Set for Tank, 2.7 kΩ - 3 m.

An immersion temperature sensor with a resistance of 2.7 kΩ and a 3 m cable length, which measures the water temperature in the domestic hot water tank and sends the signal to the boiler control. Based on this data, the boiler determines when the tank needs to be reheated in order to maintain the set domestic hot water temperature.

What to watch out for

When ordering a replacement sensor, it is important to choose the correct type according to the resistance (2.7 kΩ) that corresponds to the specific boiler/control model - an incorrect sensor type could not be correctly evaluated by the control unit.

Frequently Asked Questions

  • How do I check that “NTC Sensor Set for Tank, 2.7 kΩ” fits my appliance exactly? The most reliable way is to compare the exact type/catalogue designation on your appliance’s rating plate (boiler, tank, water heater) with the compatibility stated directly in this product’s name (brand PROTHERM) and in its technical parameters above. If in doubt, send us the exact type designation of your appliance (including the serial number, if available) - we will be happy to verify the compatibility for you.
  • Why is it important to use an original/compatible part rather than a universal replacement? Parts such as gaskets, sensors or safety components (safety valves, thermal fuses) are usually dimensioned precisely to the parameters of the specific appliance (pressure, temperature, sensor electrical resistance) - an incorrect part can cause reduced functionality, leaks, or, in the case of safety components, a genuine safety risk.
  • Does this part need to be installed by a professional? For simpler, mechanical parts (e.g. gaskets, covers, small accessories not connected to electricity, gas or the pressurised part) a handy DIY person can usually manage the replacement after disconnecting the appliance from power and supply lines. However, for any intervention in the gas, electrical or pressurised part of the appliance (e.g. sensors located directly in the combustion chamber, safety valves, electrical modules) we always recommend a service technician - especially since such an intervention could affect the validity of the warranty on the whole appliance.
  • How do I recognise that this part is worn and needs replacing? Common signs include visible wear/cracking (for gaskets and rubber parts), a water or flue gas leak at the location of the part, an error message on the control display (for sensors and electronic modules), or a visibly reduced functionality of the appliance (e.g. irregular combustion for burner parts). If in doubt, the safest option is to have the condition assessed by a service technician during the regular annual inspection.
  • Is it worth keeping this part at home as a spare? For parts that are subject to normal wear (gaskets, fuses, small mechanical parts) and whose failure would mean an interruption to heating or hot water, keeping a spare in stock is a reasonable precaution - especially for older appliances, for which it can be more difficult to obtain a part quickly.

Am o centrala Protherm si mi-a zis un domn ca trebuie sa schimb senzorul ala care simte temperatura la calorifere. Nu stiu ce lungime sa iau, la mine cablul vechi era destul de lung, se poate scurta daca e prea mult sau ce ma fac?

Bună ziua! Setul are un cablu de 3 metri, deci acoperă cu siguranță majoritatea distanțelor din instalație. Dacă e prea lung, nu e nicio problemă, cablul se poate scurta fără să afecteze funcționarea senzorului. Important e să respectați valoarea de 2,7 kΩ, ca să fie compatibil cu centrala dumneavoastră Protherm.

About the company

The company Protherm Production is part of the Vaillant Group and is a manufacturer of heating technology for many countries in Europe, Asia and Africa. For the Slovak market, it produces boilers of the Vaillant and Protherm brands. Protherm Production is not only a production plant. It also includes one of the most modern research and development centres, a testing centre and a distribution and logistics centre for Central and Eastern Europe.

The company's beginnings date back to 1991, when it operated as a seller of heating technology in Prague. Production in Skalica was initially launched in the company Didaktik, from where it was moved to the premises of the current plant in 1999. Since 2001, it has been part of the German Vaillant Group.

Three Slovak entities: The Vaillant Group employs more than 1,800 people in Slovakia. In addition to the plant in Skalica, it also owns the company Vaillant Industrial Slovakia in Trenčianske Stankovce, which produces hydraulic modules and pipes. The sales organisation for the Slovak market is the company Vaillant Group Slovakia, which also ensures further customer care and servicing of the products offered.

The Vaillant Group has a history of over 140 years and more than 2,000 patents. It is a leader and pioneer in the field of heating technologies in Europe. It has 10 production plants worldwide (eight in Europe, one in Turkey and one in China) and more than 12,000 employees. It produces equipment under the brands Vaillant, Protherm, Saunier Duval, Bulex, AWB, DemirDöküm, Glow-Worm and Hermann.

Production

Protherm Production produces a wide range of boilers and hot water heating equipment. These include suspended and stationary, condensing and non-condensing boilers, electric boilers, electric water heaters for hot water preparation and indoor units of heat pumps. Products of the following brands are produced at the plant in Skalica:

The start of production in the reconstructed premises of the company's current headquarters dates back to 2000, when 51,000 finished products were produced annually on three production lines. Over time, production gradually expanded to its current form. New projects were added and new production lines were built. Today, more than 710,000 products are produced annually at the plant in Skalica. A wide range of equipment is produced for countries in Europe, Asia and Africa. The largest exports are to Germany, Russia, Belgium, Turkey and Italy.

The most modern electronic work processes are used in Protherm Production, which makes it relatively easy to assemble heating equipment on the production lines. The work process on LCD screens guides employees through the entire assembly process, in both text and visual form. This intelligent electronic system makes production easier and helps avoid errors. In the case of incorrect use of components, it alerts us and stops the assembly of the product on the line.

The production halls of the plant in Skalica are bright, clean and quiet spaces. The goal of Protherm Production is to become a green production facility, so it invests significant financial resources into ecological solutions, innovations and focuses on energy saving.

Research and development centre

One of the most modern research and development centres in Europe is part of Protherm Production. The company can boast of a top-class research and development centre with powerful workstations, a modern laboratory and high-quality equipment. Members of the development team primarily contribute to innovations in current boilers and the introduction of new, more powerful modules. Ideas for new, more efficient products are born here, the design is optimised to improve quality while maintaining or reducing the price, taking into account new technologies and their implementation. In addition, existing boilers are further refined within the entire Vaillant group.

The main tasks of the research and development centre of the Protherm Production plant are the development of hydraulic modules for boilers, gas condensing and non-condensing boilers and electric boilers. We also find here the team of sustainable engineering (Sustaining Engineering) and the team of project and product management. The final form of the product is created thanks to the close cooperation of the development staff of the Protherm Production company with the developers from other companies in the group.

Recently, new departments have also been created within the research and development centre. One of them is the Intellectual Property Department, whose task is to register new patents. We have also expanded the group of simulation engineers, who are experts in CAE simulations.

The research and development centre currently has 63 employees. It also includes an expanded prototype workshop and a modern testing centre. What our developers design is assembled in the prototype workshop, tested in the laboratory and finally introduced into mass production.
