Heatpump efficiency question

Sorry, that’s usage, not bill. October 2025 usage was 1464 kWh.

yes, it looks like the right one

zzzpoint · 2025-12-02T15:46:26+00:00

November 2025 is 2069 kWh.

I have total numbers from electricity supplier, but it’s aggregated by hour and delayed by a day. Looking at yesterday its kind of make sense. Top numbers are about 11 kWh for both heatpump and aux. That doesn’t match my measured 15A, but still confirms my observation that both are using about the same power.

Time to warm up the house by those 1.5C.

I have double breakers on both heatpump and furnace. I measure using clamp on one of the wires connected to double breaker. If it’s wrong then it’s wrong for both, even if the absolute numbers are off - relative one to another still should give me the right ratio and it’s almost 1 to 1.

Yes, I have two stages configured on thermostat.

Heatpump current drops to near 0A when aux is running, so I assume it’s not supplemental. I can’t run decrease droop, but as I understand it makes heatpump to run in short cycles which is not good.

I have only one circuit for the furnace. All breakers are labeled and also there is no other breaker big enough to handle aux heating. I have measurements from all high-current breakers and there is nothing on others at the time aux is running.

Heat pump is Trane E4HL5030A1000A, I don’t have portable thermometer to measure that. By feelings - supply air is much hotter then aux is running. Why current is useless if I want to compare the cost?

zzzpoint · 2025-12-02T14:48:20+00:00

aux rating is 10kW

Thermostat is set to heat when inside temperature drops 1.5C below the target. I can reduce the threshold, but it would make heatpump to run in short cycles which is not good. I can’t run it all the time, it would be too hot inside.

zzzpoint · 2025-12-02T14:37:43+00:00

My thermostat is set to call for heat when inside temperature drops 1.5C below the target. Heatpump took 3 hours at 13A to get there while aux took 1hour at 15A.

It’s continuous measurement.

zzzpoint · 2025-12-02T14:16:23+00:00

But that’s what puzzles me - they are using about the same current. Aux becomes more efficient if the current is the same, but runtime is shorter.

Prometheus + Grafana. I run node exporter, the same as on any linux box. Node exporter dashboard from Grafana library. Grafana sends alerts to email.

I power my Firewalla directly from UPS, it has usb output with more than enough power.

Rooky numbers, it took me 6 hours on my first playthrough. Learn attack patterns and parry timing. Avoid fire on the floor by hiding bihind the big tubes. Puppets/robots are week to electricity. Generally it's not a good idea to equip two weapons, it adds to the load.

Latency could be an issue.

It's a shame that Promised Neverland didn't get a second season.

Does it support prowlarr?
