The performance is looking promising using BBQ propane gas. R290. The compressor and fan draws about 220 watts. I've purchased a kill-o-watt meter to confirm our calculations on the cost of usage. The blue paint is left-over from a customer's machine color. All their equipment in the plant is this color. I was amazed it's still able to be used. After all this time I thought it would be trash.

The propane burning water heater that the DIY HPWH will be replacing is about 12 years in service. The parents had rented it all those years. The rental fees started at about $6.00/month and now $22.00/month. That's a pretty lucrative return for the propane man. It just plain luck that its being changed out when the propane has made such a huge leap in price.
