@ March 7, 2014 8:46 AM in NG Combi Boiler versus indirect tank and boiler setupThanks. Anyone have experience with Navien. Amazon sells their DHW heaters. Lots of comments both + and -.
@ March 7, 2014 7:51 AM in NG Combi Boiler versus indirect tank and boiler setupThe contractors do not appear capable of performing the analysis. None have offered it. All have looked at the 25 year old oil fired boiler and 40 gallon storage tank and said that their recommended units will do the trick. At this point I am interested in the reputation of the brands for reliability.
@ March 6, 2014 9:49 PM in NG Combi Boiler versus indirect tank and boiler setupWe are planning to switch form oil to natural gas when it becomes available this summer. My contractor has recommended a Navien NCB 240 combi unit. I've read most of this thread and looked for reviews including those on Amazon, YouTube, and other sites. YouTube had a 3 part "tutorial" by a guy who runs www.profitableplummer.com. The Navien seems to have more than its fair share of negative reviews ranging form cramped cabinet to bad circuit boards to crappy customer service.
Another contractor recommend Bosch Combi 151, and another a Viessmann Vitodens combi. The prices installed range from $7,900 for Naien to $9,300 for the Bosch to $14,400 for the Viessmann Vitodens .
Can anyone suggest a good way to make a comparison as to quality and reliability? Does anyone have experience with using these units that might be a basis for comparison?
