The project was going really well. As I explained in my last post, the trenching and piping were completed. All the remaining work was to be inside. Mostly in the basement for the GSHP but also in the attic (for the energy recovery ventilator (ERV). Lots of wire pulling, circuit running, plumbing, piping, ducting and insulation was occurring. We were expecting to fill the pipes with the water and propylene glycol solution and start the system up last Thursday. Then, last Wedesday, we had a bit of a setback.
I don't want to go in to the details because the party responsible for the accident has so far handled things quite professionally and the project will only be delayed about 3-5 days (depending on how you count). Accidents happen. All that you can hope for is that people take responsibility when they happen. And so far so good. No one was hurt. We just lost a little time. I joked that the project was going too smoothly.
So we are looking forward to Monday or Tuesday for power-on! Thermostats wires are in place, but no thermostats are connected yet. The ERV switches in the bathrooms are in place and the plug was installed in the attic, but the ERV needs a few more low-voltage connections before it is operational. Plugs are in place for the condensation pumps, but we need to run the condensation pump drains. The internal ground loop pipes still need some insulation and glycol... The electrician must make his final visit to make the 3 high voltage connections (circulation pump, GSHP and aux-heat). And then we can try it out!
