my cook top hates my heatpump?

good evening (if its evening where you are )

so. i've got a fun one on my hands here. as stated in the subject. my induction cooking top won't work when the compressor of my heatpump is running.

which seems a bit odd to me. have anyone ever encounter something like this before?

its only the cooker that stops working. all other electronics is working normal (almost, i can hear the compressor running in my desktop computer, some electical noise that starts and stops with the compressor)

the fun part for me is that the manufacturer of each units blames one another. so i'm stuck with this problem.

the cooker is about 4 years old. and the heat pump is about 1 year old now. and it started when the heatpump was installed

could the pump send back electrical noise?


the cooker is a GRAM induction one. and the heatpump is a 16kw Daikin Altherma LT split (air to water) heatpump. PWM controlled. so it produces heat after demand, and not on/off as other pumps often are

damn problem is driving me nuts. turning of the heat everytime i'm using the cooker is starting to get old

oh. the electrical is 230v IT single phase. (rural norway)


all hints/tips are welcome :)

That sounds like the compressor generating a boatload of EMI.

How far is the compressor from the cooker? is there anyway you can add some space (probably not)? Could you put them on different circuit breakers (if they are on the same breaker in the panel)?

yes, but should it? should a $20k heatpump be this noisy?

hmm. about 10meters or so. the compressor is outside, on the wall

Was the heat pump a replacement item or an addition/change over?  Did you have an AC unit that didn't do this?  I'd think a 4 year old induction cooker would be adequately filtered for normal conditions.   These are the kinds of problems that popped up 30/40 years ago that delayed electronics being introduced more quickly.
