Ogden, Quebec.
Five ton (single compressor - R410A) ClimateMaster water/water (vertical loop) heat pump (with HWG)in lakeside garage/apartment addition (completed 2016) to existing log house. Seven sub floor zones and 1 FirstCo air coil (heat/cool with 15 kW backup electric heat in 3 stages). HBX ECO - 0550 outdoor reset controller sets reservoir target according to outside temperature to match load and optimize COP (warmer OAT --> lower ELT --> less heat to envelope + higher COP). Main Reservoir: 72 Gal.; HWG reservoir: 36 Gal.
Electric load (addition, main house, boat storage shed) monitored by eGauge. Backup by Kohler 48 kW generator with load shedding.
Objective: Installer clearly did not understand much about heat pumps. Goal is to determine whether my fixes are such that the system is performing as it should. And keep an eye on my electric bill.
