p********8 发帖数: 169 | 1 现在是一个很老的oil boiler,热水器是2011年新换的, 用的是gas,两个都从烟囱排
气。想换个gas boiler, 联系了三个plumber,每个人的说法都不太一样。
第一个说用Burnham的Alpine, 95% efficient , direct vent, 同时把热水器去掉,
换成indirect的。否则的话只留热水器烟囱的liner就不够用了,必须再花1000多
reline一下。
第二个建议我们用还是从烟囱排气的ES2, 85% efficient, 不用换热水器,也没提需要
reline烟囱。同时他说Alpine一般只有5年的保质期,而natural draft这种锅炉是
limited life warranty。Alpine的安装费也贵很多。
第三个也说Alpine这种锅炉的质量还没有被proven, 建议用natural draft。他推荐的
是81% efficient的series 2。但同时他说原来的热水器安装的不合标准,烟囱liner用
的是铝而不是不锈钢,必须换掉。我们可以保留原来的热水器,或者换成storage tank。
听了这些不同的意见,不知怎么样更合理。还想向这里的高手们请教,非常感谢! | G**P 发帖数: 369 | 2 Two link for your reference:

My current oil boiler is a Burnham brand, i think its quality is bad. I am
in the process of converting from oil to gas and I'll not consider Burnham
brand myself. One of the contractor that I talked to agree with me.
Some people use Buderus but one thing that I heard about is that it has an
aluminum heat exchanger they oxidize overtime due to the corrossive
condensate.
Right now, I am considering the Lochinvar Knight Series (Recommended by a
few contractors that I talked to). Lochinvar has stainless steel heat
exchanger, compared to the aluminum heat exchanger that Buderus has. Price
wise, it is about $400-500 cheaper than Buderus.
Also, High deficiency boiler (96%) qualifies $1500 rebated and indirect hot
water heater qualifies $400 rebate from http://www.gasnetworks.com/
Good Luck!
