SnakeTheSoaker Posted February 25, 2018 Report Share Posted February 25, 2018 Just purchased a fully loaded Marquis Spirit - bluetooth radio, wifi, micro silk, etc. Can't wait for it to be delivered and to get into it! We are in NJ, and the tub will be in a 3-season room (concrete slab, roof, but 3-sides are open) Question: Should we plug it into the existing 120V outlet, or would it be worth the extra expense to have a dedicated 240V line ? From research, it seems there are only two benefits of a 240V line: 1) hot tub will heat up faster 2) heater can run when jets are on high (but will run when jets are on low) What should we do ? Is the time to heat up only an issue when you initially fill the tub ? I had another tub along time ago, i would keep at 90 or so, and then heat up to 103F when we wanted to use it. Is that not a workable strategy with 120V, and we'd need to keep the water near 100F all the time ? Any other differences in performance ? thanks!

castletonia Posted February 25, 2018 Report Share Posted February 25, 2018 The hot tub will do a better job maintaining temp on 220. You are correct though, it will heat up a lot quicker and you can run jets on high speed with the heater on too. To go from 93 to 100 on 110v would probably take 2-3 hours depending on outside air temp. If you run 220v, you could have ordered it with the MP160 pump which provides more power, otherwise no difference if you wire the 110v version 110 or 220.

Cusser Posted February 26, 2018 Report Share Posted February 26, 2018 NJ climate? I'd go 240 VAC. Because if you went 120 VAC you'd likely need a dedicated circuit installed anyway. With a good cover, I think you'd be surprised how few minutes the heater actually comes on each day. And it would always be ready to use.

Jersey Hot Tub Repair Posted February 27, 2018 Report Share Posted February 27, 2018 110V will heat aprox 1 degree per hour. 240V will heat 4-5 degrees per hour. Even at 110V, you're supposed to use a dedicated circuit for the tub, so you should put a new outlet on its own 20Amp breaker in. At 110V, the heater will draw 9-10 amps. The pump will probably draw 3-4 amp at low speed. Allow another 2-3 amps for lights, wifi and overhead you're pushing 15-16 amps. You want to draw no more than 80% of the supplied amperage. Aside from the national electrical code which says a hot tub is supposed to be the only thing on the circuit, you may run into capacity issues if you use an existing circuit. It would suck to have your hot tub short out whenever a racoon walks past the motion detector light in your driveway, and it'll take a long time to discover what the problem is.

Markee Posted February 27, 2018 Report Share Posted February 27, 2018 Congrats on the tub, that's a nice one. You will need 240v to run MicroSilk. It should come from the factory with the more powerful MP160 pump if you added the MicroSilk option. Quote Link to comment Share on other sites More sharing options...
SnakeTheSoaker Posted February 28, 2018 Author Report Share Posted February 28, 2018 Brilliant, thanks all for the feedback! 240v it shall be! You guys are great Quote Link to comment Share on other sites More sharing options...
