RE:RE:This hybrid Flue-ACE announced today is an industry big dealYea thanks. Just to add a wee bit to the info . (Crossland ) mentions ''Perco-ACE '' as well , when mentioning the Hybrid Flue-ACE in the P/R .---- Essentually speaking , Perco-Ace is the burner design and style of the nat gas burner that the company has designed to fire and continue the hot water process,during the plant standby mode .--- Without seeing the unit personally,the nat gas burner will have an adjacent air supply ,with the exhaust gas discharging directly into the exhaust existing ductwork. That's as efficient as possible and thus ,the wording of 90% efficiency ,when firing on the nat gas mode with the plant on stand-by.----- It must also be noted,should a nat gas supply not be available to an interested customer,I have no doubt the company has a similar propane supplied burner already in thier design and developement facility . ------- --- Hope that gives a picture for interest parties. All good , a VERY VERY good niche product . ----- -------- OH ,and Bill ,I live only 1.5 hrs away ,and could take on a p/r job if offered. L.O.L
