The Viessmann integration in Bouwflow, from webshop to building site
With Bouwflow, the products and your prices from the Viessmann webshop land straight in your calculations, purchase orders and stock. Heat pumps, boilers, solar energy and accessories arrive with their article number and your purchase price, and Bouwflow keeps those prices current every day. Nobody retypes article numbers or prices by hand.

What is Viessmann?
Viessmann is one of Europe's largest manufacturers of heating and climate technology, founded in 1917 in Germany. Since 2024, Viessmann Climate Solutions has been part of the Carrier group, but the brand and the range stay in place.
The range runs from heat pumps (Vitocal) and gas condensing boilers (Vitodens) to solar water heaters and thermal solar panels (Vitosol), photovoltaic panels, home batteries and ventilation, along with all the accessories and spare parts. Viessmann works directly with installers: with a Climate Solutions account, they order their materials through the Viessmann PartnerShop and follow up their installations.
