We recently decided to replace our gas water heater with a tankless model. After discussing options with the Enwise Power Solutions Inc. Sales Representative, we selected the Navien CR-210 tankless condensing water heater to meet our needs. After it was installed we had some performance issues associated with the unit (length of time to get hot water and minimum flow rate for operation)upon further investigation by Enwise and Navien America Inc. service representatives, it was determined that the unit was defective and they offered to replace the unit. At that time, it was determined that the CR-210A model would be a better solution for us given our hot water needs and desired operational parameters (min flow rate less than 0.5 gal/min). The Navien CR-210A which has an internal mini buffer tank was recently installed and we are absolutely delighted with it. The unit provides hot water no different than our previous gas tank model yet it is a high efficiency tankless system, and we can precisely set the water temperture at the push of a button. Thank you Enwise Power Solutions Inc. and Navien America Inc. for your commitment to your customers from your office staff to your technical and field staff, we had nothing but support from your teams. We now have the tankless system that we desired with essentially no difference in perfomance from our tank system with all the cost savings and reduced environmental emissions.
