Compact energy storage for sustainable building technology

Cowa Thermal Solutions AG has agreed a partnership with Meier Tobler AG. The wholesaler will include the compact thermal storage solutions in its product range. Cowa plans to launch a "technological world first" onto the market at the end of the year with a new latent heat storage unit.

Root LU/Schwerzenbach ZH, November 2025

Cowa Thermal Solutions AG, based in the Technopark Lucerne in Root, has entered into a wholesale partnership with the distribution company Meier Tobler from Schwerzenbach ZH. According to a press release, Cowa intends to use this partnership to significantly expand its market segment in Switzerland. Meier Tobler, a provider of building technology products in the areas of heating, ventilation, air conditioning and sanitation, will distribute Cowa heat storage units for use in single-family homes, apartment blocks and for integration into heat pump and photovoltaic systems. This will make access easier for tradesmen in particular.

“With Meier Tobler, we have gained Switzerland’s strongest sales partner, who also shares our vision of compact and sustainable heat storage,” said André Waller, CRO of Cowa Thermal Solutions AG, in the press release. “This partnership is a milestone for us. It makes access to future-oriented heat storage easier than ever before, directly where installers order anyway.”

Cowa plans to launch a new latent heat storage system on the market by the end of 2025. The product for domestic hot water will have a phase change material (PCM) melting point of 48 degrees Celsius and therefore have a high energy efficiency. According to Cowa, the melting point of this “technological world first” would be 10 degrees lower than that of previous systems. Thanks to the low melting point, almost all standard heat pumps can be used for the storage tank.
