烧煤的关键是要清洁处理,这个只有集中烧煤才有可能。所以烧不烧煤不是关键,关键
是不能一家一户地烧煤。我党取缔煤碳是个大跃进,自寻不适,属于低水平的治国行为

By ELLEN KNICKMEYER, Associated Press
BAKERSFIELD, Calif. (AP) — Regulators in California, the country's third-
largest oil-producing state, have authorized oil companies to inject
production fluids and waste into what are now federally protected aquifers
more than 2,500 times, risking contamination of underground water supplies
that could be used for drinking water or irrigation, state records show.

那是因为这边不把这个叫“地热”,叫radiant heat。“地热”直译就是geothermal. |
|

geothermal就是初始投资很贵的 |

outside temperature goes down (when in heating mode), unless you use things
like geothermal heatpump.
Basically, "it generates least amount of heat when you need heat most". |

l****b 发帖数: 221 | 37 是的联邦政府有30%的tax credit。我们这里电钱9分一度,似乎换过来很划算。看来真
是新科技,都没有什么人用…… |
|
y***j 发帖数: 11235 | 38 国内早就比较普及了。
我爸妈他们家用的就是,但是好像不同地区地热资源不太一样的,我们那里温泉比较多
,所以他们就用了,就不交统一的那种暖气费了,而且家里还有更老的老人希望冬天早
开是制热。好像夏天还能制冷,不知道什么原理,我是听他们说的。 |

|
l****b 发帖数: 221 | 40 我们烧油,每年的油钱大概在2000到3000之间,通煤气遥遥无期。有了这个油钱肯定省
了,电估计会多一些,但是我们的电不贵,所以我觉得2000是应该没啥大问题的 |
|
l****b 发帖数: 221 | 41 是的冬暖夏凉,因为地下温度是恒温大概55度,冬天把空气弄暖然后用heatpump,夏天
直接就上冷风了 |
|
|
l*****o 发帖数: 26631 | 43 这个和房子的地理位置有关, 不是所有地方都能做的, 所以没有那么popular |

l****b 发帖数: 221 | 45 我觉得投入还好吧,减去30%的补贴,1万6、7左右,加上一部分无息贷款,7年的时间
基本上就能cover了吧,尤其是对于烧油的有一定规模的房子,一般每年都得小三千的
油费。不明白大家为啥不用。 |
|
l****b 发帖数: 221 | 46 是这样,我现在吃不太准这个是不是划算,技术是不是可靠 |
|
C**K 发帖数: 3672 | 47 曾在This Old House裡看過他們在裝這個. 聽著很不錯.
這節目基本上都是在MA這一帶拍的, 其實NE居民某些方面挺保守, 很多人還執著地用
油.
這個換起來費用比換成瓦斯還高很多, 不難理解問什麼很少人用.
直接和他們要customer reference? 很多人其實很樂意告訴你.
Boston版有人用heat pump+split AC, 據說效果不錯省了不少油錢, 不妨去那裡問問. |
|
l****b 发帖数: 221 | 48 谢谢!如果我有换成gas的option,我肯定就换了,费用差不多是换成这个的一半,但
是我这个town的gas company明确地说,三年之内肯定通不到我们的街上,三年之后再
说。。
问题是,房子3000尺,4、5年的油钱基本上就抵了这个费用了。不知道大家不换的原因
有没有别的。 |
|
h********y 发帖数: 3778 | 49 这个好像要地比较大吧?光这一点很多人就没条件
你要是做好计算了就上吧。 |
|
t***s 发帖数: 4666 | 50 地要大,把地翻一遍landscaping也要钱。大部分人懒得折腾。
我支持你上。我家就是纯air sourced heat pump。但我们在CA, 你在MA估计
不行。支持你上ground sourced。但你还要考虑你们那里电有没有累进费率。
加州电的累进费率最高$0.35 / kWh。你们那里油什么价钱?和烧油比估计
还是省钱。Heat pump在室外热源55F, 室内70F的情况下效率(COP)可以
到450%左右。你这个可能还要室外水的circulation pump的电。 |
