ᐅ Air-to-Water Heat Pump: Current Consumption and Data

The house was noticeably cooler this morning; the living room was only 21 degrees Celsius (70°F). I thought the heat pump would regulate itself, but apparently, that wasn't enough.

I then raised the heating curve by 2 degrees Celsius (3.6°F) because I was cold.

Now, after 24 hours, 42 kWh of electricity have been used to produce 128 kWh of heat, including hot water, at -14 degrees Celsius (7°F) last night.

There were 2 heating cycles lasting over 7 hours each.

Starting tomorrow, it should get too warm with the solar gain, right? We have three days of perfect weather ahead with 10 hours of sunshine. It’s just a pity that the photovoltaic system is completely covered in snow.

What kind of nonsense is this? It has been running for 10 hours.

Good question, is it still heating?

We have consumed 32 kWh in the last 24 hours, producing 100 kWh of heat. The average temperature is now -9.5°C (14.9°F), the lowest temperature last night was -18°C (0.4°F), currently -14°C (6.8°F).

No, judging by the inverter’s consumption display, the house load is currently about 450 W, which means it’s basically off.
The heat pump should be running, but something has happened with the supply temperature—no idea what.

I’ve just started the fireplace for now. The Luxmatic manual says that heating up the compressor happens during initial operation and can take several hours.

No idea what’s going on.

I’ll have another update early tomorrow morning, really looking forward to it.

@Zaba12 according to the graph, your house should have cooled down to around 5°C (41°F) room temperature by now 😀 I think there might be volcanic activity under the slab.

Turn off the circuit breaker and observe what happens next.
