Heat pumps: a screen of providers and reviews?

This data-file tabulates our subjective opinions on c20 different heat pump companies, and our own preferences to use their heat pump on a future European residential heating project.

Factors we have considered include pricing, reliability, efficiency, company size, the range of models, integration with home smart energy systems, and visual/acoustic properties.

A large portion of the work was based on tabulating customer reviews, from online forums. A key challenge is opacity, as many companies do not provide full pricing details on their models or have many customer reviews.
