HP water heaters can be a smart choice

摘要

"I haven't offered heat pump (HP) water heaters because I don't have an EPA refrigerant handling license."rnThe good news, no make that great news, for my friend and competitor who said that: he doesn't need the license to sell and install HP water heaters. The refrigerant circuit is self-contained. The potentiallyrnbad news is that failure to follow a few basic guidelines will increase operating costs for his customers and potential for service issues he'll be forced to correct.
