Thanks for the diagram docjenser. An improved control strategy for my configuration would be to have the DHW aqua stat make a separate call to...
That’s an interesting question. I don’t believe I will be able to get the water tank temperature to 130 degrees using load water from the heat...
Absolutely such hot water heaters are available. In my opinion, in a heating dominated climate zone it is wise not to rely on the desuperheater...
Sounds expensive ! And your foundation contractor will probably not like it.
You can see the installed link seal kit just to the inside of the rigid crawl space wall insulation. This is two inch HDPE header pipe inside 4...
I have not seen such a system. A drawback would be multiple pipes through the same hole - requires a large size hole which may jeopardize the...
For sure you need to add antifreeze to the supply loop. If EWT was down to 44 degrees then LWT may have been 36 to 34 degrees - dangerously close...
In my new build install, I included 1/2 or 1/4 inch ports to accommodate temperature and pressure monitoring on both sides of the supply and load...
I agree 100%. Over sizing the loop field is cheap insurance. A minimal amount of excavator time and cheap loops of HDPE pipe. Heat of...
You have 1600 feet of 3/4 inch horizontal hdpe pipe per ton of heat pump capacity. Accordingly, your loop field is way over designed. BTW, I...
What are the specifications on the ground loop ? Pipe size and length ? You have nine boreholes - correct ?
The two heat pumps share the same closed loop - correct ?
What is your closed loop flow rate through each pump ? Maybe there is not enough flow for the two heat pumps to run simultaneously? Thus the...
The big news - I am making hot water ! [ATTACH] Commission load side by flushing with 1/2 HP transfer pump through piping and buffer tank....
Latest update - closed horizontal loop now operational. Electrician connects all high voltage 230 Volt wiring to heat pump, flow center and load...
