Thermia Spare Parts

 Welcome to our Thermia Spare parts sales!

Thermia was started in 1923 in Arvika, Sweden among the deep Värmland forests. They have since developed tomorrow's heating solutions.


All our Thermia spare parts are original from Thermia, which ensures both longevity, warranty, and efficiency of your Thermia system. In our range you will find outdoor sensors, display kits, temperature sensors and soft start cards for many of Thermia's various heat pumps, including for Atria, Diplomat, Diplomat Optimum 2G, Diplomat Optimum 3G and many more.

All our heat pump spare parts are covered by a 12-month warranty, all to give you as a customer as much safety and security with your heat pump as we can. 


To make it easier for you as a customer, we have chosen to divide our spare parts for Thermia into two different categories, a category that contains all the different spare parts per type and a category that is aimed to you who know what type of pump you have.


If there is a spare part from Thermia that you cannot find or something else that you are wondering about, please contact us and we will help you. You can reach us on chat every day between 8am and 9pm, by phone (+44) 8082 8080 07 or by email


On our page JS Education, you will find lots of useful information regarding the established brands of heat pumps and boilers. There we have collected user manuals, product sheets, installer manuals, electrical diagrams, service manuals, guides as well as answers to common questions about spare parts and functionality.
