Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

BTW, why do two 50m wells ? A single 100m is far cheaper and just as efficient. Only when one requires more well depth than the max collector length (usually 400m/1312 feet) can support it makes sense IMHO.

Viessmann has a system of variable flow rate pumps, so they save on the flow pumps by switching off a well if it's not needed. And you have less load loss with shorter parallel fluid circuits than with a single long one. For horizontal collectors, they also have between 1-8 separate circuits, depending on the heat pump size, for the same reason.
