hydraulic heating and hot water sytem
« on: October 15, 2008, 11:21:13 AM »
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.
greetings
walt

Thanks for the info.
Is this hydraulic heater commercially available in Germany and where to order?
Let me know.

Hi all,
here the link to the patend
http://www.wipo.int/pctdb/en/wads.jsp?IA=DE1994000669&LANGUAGE=EN&ID=id00000000680682&VOL=9004&DOC=008496&WO=95/014896&WEEK=23/1995&TYPE=A1&DOC_TYPE=PAMPH&PAGE=1
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

Walter:

I found the above video on youtube.  This system claims a 70% overunity by heating water through friction.  I was not sure if this is related to what you were talking about.

Has anyone else seen this video or know anything about this?  If this is really 70% OU then why have we all not heard about it?  Or, possibly, everyone else knows but me?

Stefan:

Have you seen this video?

Hi bill,
no this is totally different, first he uses water as medium in the hydraulic system it is hydraulic oil, second he uses a vortex compression with high rpms.
the probleme what I got is I have not seen any calculation what means the factor's what he uses to calculate OVERUNITY.
the hydraulic system what I talk about has been put through a approval system in germany from a major university where the measured and calculated effeciency is 98.1% as a whole house heating and warmwater system. it uses between 5 and 10 Kw on electricity.
from my own experience on practical application the hydraulic oil holds the temperature a verry long time and just gradualty declines. the comparisson from homeowners who had before on the same house system which was fired before with natural gas against the hydraulic system was that they safe around 38% and the feeling was more all around warm.
I personly have build a test version at the time which used a 2Hp motor with a hydraulic pump from a car steering in a steel housing the size of a regular room heater with about 5 galon hydraulic oil and I could heat a room of 240 Sf up to 80 degree F and it only used around 8Kw over 24 Hr by a outside temperatur of minus 10 degreeF. with the regular room heater i could not even bring the temperature over 70 degreeF with a usage of 24 to 30 Kw.

Hi Walter, could you post a picture or a drawing of your car power steering test setup. Did you use a car radiator as the heat exchanger? Thanks!!

Walt
  Was he using a standard hydraulic oil pump or a type of water pump pushing oil in the version used for heating a home?

@ Walter

1. Thanks for the information about the german hydrailic heater. After reading the patent I did some internet reseach but I couldn't find any information about it. You can say it's an instance of suppression. I don't believe.

2. Bill have drawn out attention of a youtube video. It seems that you know somethink about it (vortex compression with high rpms). Can you give out further information.

Best wishes
Alana

t’s no surprise that companies Secure Home Services using R-410A refrigerant compatible systems are seeing an uptick in business, as R22 becomes increasingly difficult to obtain, rendering systems that utilize R22 obsolete.
