Bush tucker

 

End of play today

 

You don’t have a truck ?

 

Looks great. What is it ?

 

Ground source heat pump,running a big oak framed house
Heat pump on the left,buffer vessel next on the right,divicons unmixed the 1st one that’s for a pool,then 2 mixed circuits for UFH
In between the divicons there’s a plate heat exchanger then a 750ltr cylinder

 

So...what's the source of the heat?

 

The source of the heat in a ground source heat pump is the ground.

 

Yes, Mr Clever Clogs . But...what's in the ground doing the heating? Has @Richard W12 drilled through the earth's crust?

 

Ground loops in the ground about a metre deep full of glyco (a form of antifreeze) we take about 6deg send it back about 1 deg

 

Wouldn't have though you could recover that much heat. Surprising.

 

Open loop bore holes are the most efficient,you strip At about 11degr send it back about 7degr allegedly 300% efficient
