The backup are heating elements in the hydronic tank. So it would have to be kWe because it wouldn’t be refrigerated.Is that 24 KWr or KWe? Two completely different things. KWr is refrigerated KiloWatts and KWe is your Power Kilowats... have a look at the manufacturing Specs on the Heat Pump.
Heat pump max current is 28.6 amps at 220v. Sorry I probably should explain a little better. The heat pump will be air to water for hydronic heating. Heat pump heats up the glycol tank. Where it will be installed the weather can get to -30C for a couple days a year. Heat pump shuts down at -25. Glycol tank has 6x4 kW elements for backup in case the heat pump can’t keep up or after -25 when the heat pump shuts off. So those few days a year the electricity will be stupid high but only for a couple days.Heat pumps I deal with use refrigerant for Heating ie R401a or R32. If your Heat pump uses elements rated at 24 KW, God help your electricity bill. I assume your Home is split phase? 220V? Look on the decal plate on the pump for current rating at 220v
Kylbees welcome to the forum and yes your panel can hold the load the load their giving on the instructions Is max load to size you breaker. In real life it probably wouldn’t pull over 35 amps at most and that’s only when the heating elements kick in after the water temperature setting is met the elements cut offHey, Just a question for a heat pump install. Heat pump unit is 60 amps. Backup in tank heater for hydronic heating is 24 kW. Just don't know if the 200 amp service will be enough for the heating load? Any advice on service calculation on this particular setup?
