I've been waiting to do this video for quite a while to explain why I don't agree entirely with the philosophy of open loop systems with heat pumps. using simple mathematics I demonstrate how the secondary flow in a system is lower than the primary side when you use a buffer with two or more mixed circuits. this demonstrates that no negative impact results from the use of a buffer and mixers. the heat pump only has to run to the temperature required by the higher temperature circuit on the system.
