I understand what you want to do after your last post. Check the voltage between the hot sides of the 2 receptacles and if you read 240v it should work.

Thanks Jim. Checked with multimeter. There both in phase (same line)
I:
  • Set my multimeter to measure AC volts.
  • Stuck one probe in the ungrounded (hot) side of one receptacle (the smaller slot).
  • Stuck the other probe in the ungrounded (hot) side of the other receptacle.

I was hoping they would read 240, then the receptacles are on separate legs. But I measured 0 volts, they're on the same leg. They both measured 120 from either hot to either neutral.


Still, if someone else reads this it is completely possible to install a 240 volt heat pump dryer if you test 240 volts hot to hot on two plugs and use the Parkwood combiner to plug the dryer into.

Are they on the same breaker? If not, can you move breakers around?
Same breaker. But I'm going to check the hot wire to the water heater. I put in a Suburban Nautilus tankless water heater and capped off the electric side. If it's on a different leg I'm in business. Although plan B would be to have an electrician run a line and it's own fuse box from the junction box. But that just sounds like too much work.
