Re: Generator doesn't work with Direct Vent Hot Water Heater

Again yes, but you can't really (even if you could it would be wrong because it's against code) power a water heater off of an extension cord (other than a tankless single sink one perhaps).

Really? Why and why can't you power a water heater with an extension cord as long as the capacity of the cord and the protections are correct? (Breaker or Fuse size).

Simply because you have to use solid wire (romex or THHN) or stranded THHN to connect hardwired appliances (non-vibration) or using SOOW if it is a piece of vibrating equipment (like a motor).

Really? In 52 years of electrical work I've never heard that. Looks like my Heatpump is out of compliance and illegal. It has Romex to the pull out disconnect but THHN stranded to the unit which definitely vibrates and has a motor (Compressor).

As far as the water heater I can sit it in the yard and wire it up with a portable cord to the generator and use hoses to connect the water to the house.

Not really, since it's not a requirement to use SOOW cable for vibration-prone devices, just a recommendation to prevent wear on cable. The use of THHN though is a requirement (same requirement where you can't use SJT or lamp cord to wire outlets).
