   埃里克,
   Here's an article that may help you:
   Heating a Tight, Well-Insulated House

   Thanks Martin,

   我读过这篇文章通过几个蒂姆es and the included two pages of comments as well. It was what initially got me very interested in minisplits! The reason I posted a question was because of two factors: My house is essentially a three zone animal, making it harder to heat all of it from a single point source, and it is in a cold area (Durango, CO, zone 5), making the option of minisplits possibly questionable. Just like one of the comments on the article, the Mr Slim hyper heat models (which would cover the cold temps we see here) only come in single zone configurations, not multi zone, making the installation of three of the these units to cover my three zones rather expensive. Local heating contractors just suggest radiant or a hydronic system at $15000 install price tag, which is just not in touch with the whole idea of super insulation. I am very interested in the minisplits, but I am concerned that they might not provide the heat needed for our typical overnight winter temps. If I install a multi zone minisplit system that would be the most economical for three zone installation such as sanyo's multi zone system, they claim to produce heat only down to 4 F, and at a reduced percentage of capacity. I guess what I am asking is if you or anyone knows of any cases where a multizone mini split system has been used with success in a similar climate to Durango, Colorado (~7000 heating degree days) and of course all of the details on its usage: install cost, operating cost, success at low temperatures, etc.

   再次感谢。

   埃里克,
   Whatever type of heating system you choose, improvements in the home's envelope will lower your energy bills. Choose the best windows you can afford, and strive for a very low level of air leakage.

   Any of the heating systems mentioned in my article will probably work successfully in your house. The choice is yours.

   如果您选择安装多Zone Minisplit热泵系统，则可以随时安装一些廉价的电抗性底板单元，以在罕见的夜晚提供补充热量，当时户外温度下降到-10摄氏度以下。

   埃里克,

   马丁当然有很好的建议。如果您的气候如此寒冷，则可能有意义地使用热围栏（例如R-40墙壁和R-60天花板）走得更远，并仔细注意窗户和门的细节以最大程度地减少热桥梁并确保空气紧密。这应该有助于某些人进行热分配，但是单个区域热泵似乎不可能均匀地加热三个水平。您可以安装两个高温单元，一个在底部，一个在顶部。

   I just installed a system in a home like what you describe. We used a used Burnham boiler from a recent boiler upgrade and tied it to the woodstove with an indirect tank as a buffer. This was mated to 2 Runtal flat panel radiators per floor. When they are home, the house is heated with wood and when they need supplemental heat, the 80% efficient cast iron boiler fires. The indirect tank has 2 heat exchangers, one for hydronics and one for solar, the water in the tank is DHW. This is a log home, so I'm not sure what the wall R-values are, but the ceiling is insulated with 8" of foam for about R-56. We are about 8000 HDD.

   We've only used ductless minisplits in single-floor applications and when necessary have had good results with hi-lo stud-space chases to circulate air from room to room using small quiet low-energy fans. Using a similar principle of gentle forced-air circulation independent of the minisplit fan unit, it occurs to me that the natural stack effect in a well-insulated three-story structure might be beneficially exploited with a simple vertical contraflow duct and fan to return warm air to the lowest level to ensure even distribution of conditioned air. An amply-sized straight-shot chase with no elbows would minimize fan load. Thoughts?

   I'm just finished up my own house (will it never end!?) that's similarly sized and insulated. Climate zone 6 for me (NW Iowa). The biggest difference is that mine is all one level (slab on grade). Interior size is about 950 sq. ft.

   10" double stud walls with dense pack cellulose and R-70 attic.

   计划从一开始就将一个小的木炉（1.1立方英尺的火箱）成为我的主要热源，但是关于备份热源该怎么做的问题给了我很多麻烦。我仔细地看着迷你切片，但至少对我来说，一旦我开始寻找可以在我们拥有的冷温下输送足够的BTU/HR的单元后，成本就变得非常昂贵。特别是对于很少使用的热源。

   最后，我决定去电动底板。不，这不是最便宜的跑步，也不是性感的，但是便宜且易于购买。易于安装，易于将其钩在区域中。没有运动部件。没有维护。这房子很小且隔热良好，所以这并不是像他们被安装在2层的100年历史的Artafty房子里一样。

   我能够以大约250美元的价格购买足够的房子（不包括恒温器）。这至少比我正在寻找的迷你切片要低5000美元。$ 5000购买了很多电力。

   我尚未安装它们（现在完成干墙），所以我不知道他们将如何加热该地点或用多少能量来做到这一点。现在只有木炉正在运行，它像冠军一样加热了这个地方。我意识到您的木炉对您的多层次事件不会很好。

   就像我说的,我的英国航空公司seboard is only there for a backup for when I leave town for a few days and can't feed the stove. You're situation is a little different. Still something to think about.

   Good luck!

   用电踢脚板备份在地下室中的颗粒炉。这里的颗粒是低成本的，炉子可以比木炉更长的时间无人看管。迷你拆分主楼层，带木棍。电动踢脚板返回大师。我敢打赌，一个小球炉从地下室完美地加热了整个地方。迷你拆分也可以很好地冷却所有地板。

   （如果有的话，天然气是安装的成本非常低的选择和燃料的成本。但是，如果需要很少的天然气，例如在超级绝缘的小房子中，每月的基本成本太高了。）
