punktwissen: Elke Stangl and Sigi Proyer - physicists and professional tinkerers.
We support other tinkerers with building a tailor-made heat pump system using a water/ice tank and a solar collector as a heat source: Sizing, detailed planning, step-by-step instructions - also in remote-only projects.
The control concept is as essential as planning the hydraulic design. As IT freaks we program control units UVR1611 / UVR16x2 by Technische Alternative, and we support with monitoring, data analysis and secure integration with the 'internet of things'.
punktwissen means: Technical information and vendor-agnostic consulting boiled down to the essentials. We believe it is imperative that you know and understand your systems in order to make informed decisions. Control logic must not be tucked away in a black-box.
punktwissen also means: Support at the neuralgic points of a project - when and only to the extent it is really needed.
