Trying to figure out the total draw on the circuit for my pool to see if I can put a small fridge outside ..... Cant seems to find the amp draw on my pump or heater. Right now they are both on a 30 amp circuit.

The pump label only shows.... Model UST1152 Volt 115/230 RPM 3450 The amp draw section of the label is blank but there is a section for max amp that reads 18 (just seems like the 18 is awful high) I believe it is a 1.5 HP

My heater is a Hayward Gas H250. I believe the amp draw on this is minimal since the only electrics are for the control panel and the electronic ignition.

If anyone can offer any help it would be appreciated.
