Researching New Hot Water Heaters
My house was built in 1997 and we are probably overdue on replacing the hot water heater. The current heater is in the Garage and I want to get the house down the road of eventually needing to be in Zero Net Energy. The plan is to replace with a HE Tankless and a recirculating pump. I found that Navien makes the tankless ones with the recirc pumps built in(NR240A or NPE240A). This would be a great option but I can't seem to find comprehensive reviews out there. Does anyone know what the difference between these two models are? Also, if you have been having problems with your unit, I would like to receive constructive feedback as to what was the cause and how difficult it was to correct.
The plan is to have my plumber (ex-commercial plumber) who is also my neigbor install the unit.
Thank you for any feedback.
