跟着老板娘讨论OIL转GAS的帖子,这里再开一贴,大家讨论一下gas fired boiler
rating吧。
我在网上找了一圈,只搜到一个相关的文章 (http://www.hvac-for-beginners.com/boiler-ratings.html)。不知已经装过和正准备装的大家有什么看法。我原本打算装BUDERUS的SYSTEM,现在有点犹豫了。
Boiler Ratings, A Repairman Reviews The Brands...
With our boiler ratings you can cut through all the sales hype and find
value. We have researched the manufacturers' data and combined it with our
years of heating system service experience to provide our unique system of
ratings. It truly is like taking a repairman with you while you shop!
We have given each brand a rating from 1 to 5 stars. A 5* rating means that,
if we were shopping for our home, we would select that brand (if it was
available). When more than one brand has a 5* rating, we would choose the
least expensive one. An NA in place of stars indicates that the brand does
not have a brand in that category or we could not find enough information
about it to make a good choice. We have also included our comments on the
advantages and disadvantages of each brand as well as the manufacturers' web
addresses.
We have ranked gas fired boilers in three categories. The first group is our
atmospheric boilers. They are the least efficient and usually the least
expensive. The second category is sealed combustion units. They are a little
more efficient (up to 89% afue)but they are more expensive. The last group
is for high efficiency units which are commonly called condensing boilers.
These units have an AFUE of 90% or more but are also usually the most
expensive.
BRAND----WEB ADDRESS-----ATMOSPHERIC----SEALED----HIGH EFF.
ALPHA alpha-innovation.co.uk --NA--------NA-------<1* These boilers are made
and sold in the U.K. The InTec S models are wall mounted and feature
stainless steel heat exchangers for durability. They offer an optional
diverter kit for domestic hot water production. The warranty (especially on
the heat exchanger) is not very good.
BRYANT------bryant.com-----------4*--------4*--------3* This brand is from
CARRIER INTERNATIONAL. The LEGACY LINE (BW1A & BW2A) units can be used on
either water or steam systems. They have an electronic vent damper for
energy savings, durable stainless steel burners, and a cast iron heat
exchanger. The PREFERRED SERIES BW3A units are induced draft units for
easier installation and a little higher efficiency than the LEGACY line.
They are for water systems only and are backed by a good guarantee. The
PREFERRED SERIES BW9 have an efficiency of up to 90% and can be vented with
pvc pipe for ease of installation. They have a cast aluminum heat exchanger
which is lighter and more energy efficient. The warranty is pretty good but
not the best in the class.
BUDERUS-----buderus.us-----------1*--------2*--------1* This brand is from
BOSCH THERMOTECHNOLOGY CORP. The LOGANO G124X is an atmospheric model with
an 86% fuel efficiency and durable stainless steel burner but the warranty

我准备装national grid提供的 burnham alpine,只能希望运气好点儿了。 我看网上
什么牌子都有不少complain的。
你说的那个lochinvar好像是比较流行,不知道是不是因为装这个他们利润比较高。 不
过你得搞清楚到底有多少rebate. 我记得lochinvar的AFUE是<96%,只差一点点rebate
要少几百。

GIDP 你做的 Research真是仔细, 赞一个! 真是造福Boston版呀。Oil to gas 是
Boston住家的大事,我们要多多加料。
(八卦一下: 一次看房子,邻居老美来了,专门对Potential buyer说,“我们这条街
已经有两个人同意换 gas 了,你要是买了加入是第三家,这样总共2万多的埋管费,你
要分摊 $7000. 这只是接Gas的费用。然后还有换机器的”,这个是老美,连腰包不鼓的
老美都要换gas.)
你一定要看看这个link:
http://www.masssave.com/residential/building-a-house-or-additio
上面说了, Hotwater >96%AFUE 有 rebate $1500. 这样的话,虽然Boiler贵一些,但
是rebate比furnace高$700,算下来贵的也不多了。
