zich6 Posted December 25, 2021 Report Share Posted December 25, 2021 I have a Costco Devine Sinclaire 3 pump tub rated at 48 amps and it's on a 50amp breaker. I need to know what the heater amp draw is without the pumps. It's not in the manual and Devine hasn't called back yet. Thanks. Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted December 26, 2021 Report Share Posted December 26, 2021 Typically between 16 and 24 amps. Your heater should have a kw rating on the unit. This is kilowatts, so a 5.5kw heater is 5500 watts. Divide watts by volts to find amps. So a 5.5kw heater rated at 230v draws about 24 amps. Actual amps will vary slightly, as actual voltage varies slightly from location to location. 1 Quote Link to comment Share on other sites More sharing options...
zich6 Posted December 28, 2021 Author Report Share Posted December 28, 2021 I looked on the heater and it has no separate amp rating. I'm familiar with the KW to watts conversion. I have a call into Balboa and Devine. Thanks. Quote Link to comment Share on other sites More sharing options...
