Saunier Duval, which forms part of the German group Vaillant, is France’s largest producer of heat pumps. The Nantes-based subsidiary is benefitting from the group’s latest innovations and is carrying out major investments and recruitments.
Leader in the European market for domestic heating appliances, the Vaillant Group sold 2.5 million heating appliances and 1 million hot-water appliances last year.
The Saunier Duval plant in Nantes currently employs more than 650 employees (up from 540 in 2021) and has planned to hire nearly 450 new recruits by 2030. The factory’s production capacity has recently been increased by 50% and more than 100,000 units will be manufactured there in 2023.
A pioneer of energy-efficient heat pumps
In 2019, Vaillant launched a new heat pump, named aroTHERM plus, which is based on a natural fluid, called R290, that has a GWP (Global Warming Potential) of only 3. More than 50,000 have been installed throughout Europe. They combine high performance with an energy efficiency of up to A+++, silence and durability.
The group also offers gas condensing boilers which are already optimised for the use of green gases, and in particular up to 20% hydrogen. The objective is to develop a new generation of products that will be fully convertible to 100% hydrogen.
Smart monitoring solutions
Saunier Duval has developed a connectivity gateway for its heat pumps, MiGo Link, which offers useful services to the installer (quick connection technology), to the customer (who can use a mobile app to configure the equipment and connect it with a voice assistant), but also to the after-sales service (remote problem solving).
The high-end Vaillant heat pumps can also be connected with myVAILLANT pro, an innovative solution which allows for the remote maintenance of power generators.
Thanks to these innovations, the German group is growing fast and will keep investing heavily: the plant in Nantes will benefit from €10 million each year to help develop the site.
