Swissframe AG has made it its mission to offer smart bathroom installations in a bid to massively reduce the renovation and energy costs of apartment buildings and rental apartments. Working alongside three universities of applied sciences, the bathroom solutions company has developed a false wall system concealing a heat pump that revolutionises the production of domestic hot water (DHW). 

DHW production typically takes place centrally in the basement, with the water distributed to the residential units. This can lead to energy losses through the pipes of up to 50%. Collaborating with the Bern University of Applied Sciences, bathroom solutions company Swissframe has developed an innovative approach based on a SIMATIC control system, in which all the apartment’s DHW is produced decentrally in its bathroom. The SIMATIC S7-1200 is suitable for automation tasks in the low to medium output range – even, thanks to its compact design, where space is limited. 
The control system ensures that DHW production is energy optimised and that residents always have sufficient hot water. The system saves 70% energy compared to a conventional electric boiler.
