COP of 5

[MrMag]

Just want my fellow Canadians, especially the ones living in Ontario to know about a new Government incentive.

The Ontario Government is willing to give you up to $5,000.00 to replace your existing furnace with a new geothermal unit.

I presently own 2 units from Waterfurnace. One is a closed loop system and the one in my shop runs from well water. They are older units around 20 Years old. My place was built by one of the original owners of Waterfurnace. The COP of my existing units are around 3. The new units range from 3 up to a COP of 5!  Unbelievable!

Check out the Waterfurnace website. There is a Canadian and American website. I am not sure if they have any dealers in Europe. I would highly recommend these units. (I am not affiliate with Waterfurnace in any way, just a very satisfied customer).

I'm sorry, but how exactly do you see a geothermal power convertor as over unity?
I don't get it...
How can you get a COP of 3 or 5, in other words, how can you get 3 to 5 times as much energy from the earths heat
than the earths heat provides? How can you get 5 times more energy from geothermals?
Sounds impossible to me...
The best you can do is convert 100% of the geothermal energy into usable power...

I am far from being an expert in this field. It was explained to me this way, for ever unit of energy you put into the system, you get 5 units of energy out. It works along the same line as a window air conditioner. How do you get cold air out of it when the temperature outside is so hot? In the winter time you turn the window unit around and now you are getting warm air inside. The biggest difference is that this unit uses a constant ground water temperature to do the conversion. Sort of makes sense if you sit back and look at it.

Another way to look at it is, say that the "100% of geothermal energy" is 10,000 BTU. This would mean that it would take me 2,000BTU's of electrical energy to get it.

Hi,

Just because something has a COP>1 does not mean its overunity.  COP is different to Efficiency.  A solar panel as low efficiency of 15% but a COP>1.  A heat pump is will known to have COP>1 but a low efficiency.  It is well documented, but a lot of people think they mean the same thing?!  COP only cares about the input you have to pay for?!

Then again I could be talking out of my ass.
