Voting rules: Choose the pump you think is the most popular!
This is a community-based ranking of the most popular heat pump. We do our best to provide fair voting, but it is not intended to be exhaustive. So if you notice something or pump is missing, feel free to help improve the ranking!
A participant may cast an up or down vote for each pump once every 24 hours. The rank of each pump is then calculated from the weighted sum of all up and down votes.
