hydraulic heating and hot water sytem

[Walter Hofmann]

Hi all
I just uploaded a copy of the schematic and description ( in german) of a heating and hotwater system which is using a hydraulic oil pump system to generate hot water for a whole house heating and hot water  with a effiecency of 98.1%.
I have seen this system in action in 1992 and was amazed about the savings on electric cost.
the schematic can be found under hydraulic heating system it is in pdf format.

Hi all,
here the link to the patend

I dont know if the company still exist and manufacture this anymore, I just know that they had a hard time to sell because of the big loby of the usualy installed heating systems. I was involved in the marketing and know we sold only 15 or 20 such sytems.
here is the oldest of the patends
