Iowa -22 degrees and geothermal

So today is the coldest day every with with geothermal.
-22 degrees air temp, wind chill -46.

My WF Series 7 is maintain 70 deg inside the house without the use of Aux heat.
We will see how she does with one more night of -25 degrees forecasted.

I will say, a house makes a lot of weird noises when it gets that cold!

 

That's great.

472 watts seems like a lot for the loop pump. What pump are you using?

 

FCV2-GL

Had I done some research before hand, I would have requested an FCV1 installed instead.
When this flow center dies. it will be done!

 

Wow that great can keep up when it is that cold.

What kind of loop do you have?

 

Closed loop.

5 wells, 205' long, directional bored at 10-15 feet in depth (or at least are suppose to be, but I don't see any indication that they aren't)

 

Looks perfect.....just the pumping

108 watts for blower seems awesome, very efficient ductwork!

 

According to Symphony,

here is the usage and temps for this week.
