Thermocast Sàrl, at Rte des Fournaises 49 in Sion, focuses on heat pump heating systems in Valais and puts after-sales customer service at the center of its offering. Its range extends from full installation and commissioning through ongoing maintenance to remote monitoring and a dedicated point of contact. For systems holding more than three kilograms of refrigerant, the company flags the legally required periodic leak check.
The business was founded in 2016. Stiebel Eltron is named as the partner for heat pump replacements, and customer testimonials come from Valais communities such as Réchy, Fully, Uvrier, Savièse and Vétroz. The website is in French.
