If they diagnosed the system as low without just adding some fluid themselves, I'd be suspect on their experience. They may have measured the low...
Only as a last resort. Most people would wish to do the opposite - go to closed loop from open loop. But that being said, leave it accessible...
Your water-water (radiant) heat pump right? Most fancy controls only allow the heat pump to come on with two calls: a zone call and a setpoint...
I have not seen a spacer for double pipe before. Doesn't mean they don't exist, but I have heard of them. Not that it would add to efficiency...
On a fully functioning, properly installed/designed system - just switch as per your comfort level. No special considerations required.
How are you ensuring only 15gpm (or what is required) goes to the heat pump (flow restrictor)? What are the real world readings on the flow to...
The "cheap" software will not show the difference in this type of drilling unless you specify different soil types. As an example, you'll get one...
Caveat - rules of thumb follows. And I don't want the lay person thinking this is how to design a system. One could say the top 20' is going to...
What unit model #? And is that a fault 6 off the board or the comfort alert?
You can also verify a users comment history to get an idea as to their perspective (bias). It pays for itself quite quickly in my area -...
It will then be hard to balance the system and you will have constantly running pump(s) unless this is not a standard type job.
Are there multiple units in parallel with the system?
I'll also add, the drilling costs for soils or rock are the same around here. They just have to setup for it. Overburden can throw a wrench in...
Well you could coordinate the 3 calls with using relays. There are multiple pull 1 throw relays on the market. That's a simple solution. Do...
Have a pump on a switch that circulates all the tank water so they are a consistent temperature. Turn on when 3 tank demand is required.
