ᐅ Air source heat pump and condensate pump on the same electrical circuit?

Hello everyone,

As part of a new build last year, an air source heat pump, a WPL 09 ICS classic, was installed at my home.
A condensate pump is connected to the unit.
Now the question: Currently, the condensate pump is plugged into an outlet that is on the same electrical circuit as the air source heat pump. Is this correct and considered best practice, or would it make more sense for the condensate pump to be on a different circuit from the heat pump itself?
Thanks for your opinions.

Best regards

It has no impact and can be connected as long as the electrician is skilled. Provided that the circuit breakers have the correct tripping characteristics and ratings, and the cables have the appropriate lengths and cross-sectional areas.

Thanks: the following happened during this year’s maintenance: the circuit for the air-source heat pump was switched off to carry out the maintenance. During the maintenance, liters of water came out of the air-source heat pump. Since, due to the current setup, the condensate pump was also off, you can imagine what the basement looked like. That’s how we even noticed this problem...

I have received different feedback: some say this must happen because the air-source heat pump shows an error if the condensate pump is defective (although I have to admit I am not aware of such a function), and others say this is unacceptable, especially due to the annual maintenance (if you know about it, of course, you could unplug and reconnect the condensate pump during maintenance)...

Now, the fact that water leaked during the maintenance and was not pumped out mainly points to the person responsible for the maintenance not paying attention.
