We found this video atWhole Systems Design，这是一家位于新英格兰的公司，负责识别、设计和开发人类栖息地。用他们自己在网站上的话说:“我们设计并实现了利用当前太阳能运行的可再生食品、燃料和住房系统。这些家园、农场和学校适合迎接石油峰值、气候变化和经济转型的挑战。"
By running water through a giant compost pile, it was brought from 7 °C to a blistering 62 °C. Not much more needs to be said that the video doesn't say. We love seeing stuff like this, if you come up with your own brilliant backyard inventions or hear of one, by all means tip us off.
I would say that the tasks you’ve listed are far beyond what you’d be able to accomplish with aheat pump water heater. To simply meet the heating requirements of the house you’d need to have a dedicated boiler for the floor, and one that is sized to meet the heat load of a building that size. Here is out page that covers that topic, have a read -
All about heat pump water heaters
But speaking even just for your domestic hot water needs, I would suggest the bigger one. The thing about a hybrid heat pump water heater is that it’s in your best interest to keep it in heat pump mode, and only have it running off gas or electricity in rare cases of high demand for hot water.
A larger reservoir would mean a greater chance that it can stay in heat pump mode, so to that end you would also be wise to install low-flow fixtures, and as that is a large house, I would also consider a hot water circulation loop which keeps the source of hot water closer to the fixtures. That will shorten the wait for hot water when you turn on a tap, and help it continue to operate as a heat pump as it will need to inject less cold water to replace what went down the drain while you waited.
You will often seePex tubing in most new home constructionnowadays since it is so muchfaster and cheaper to install than copper piping. The main speed advantage with installing pex tubing comes from the fact that it is flexible, so you canbend it rather than need to create an angle junction就像你对铜一样。There is a specific brand of pex tubing calledPropex from Uponor(who partnered with Milwaukee to develop a specific tool for it) that is evenquicker to install that standard pex. See it in action in the video on this page, it’s a game changer for plumbing –
Propex installed with a Milwaukee expander tool is faster and easier than standard Pex
Some plumbers don’t like using Pex as they see it as being less durable, but that really has to do with the quality of the installation rather than the materials. Pex can be punctured by a poorly driven screw or nail where copper would not, but our advice would be just don’t put screws and nails in it.
That’s a great question, and a great practice.Insulating hot water pipes can show a savings of up to 20% on your totalwater heating costs.
There are a few products used forinsulating water lines比如一个简单的泡沫护套，它的绝缘值约为R-2。这是住宅建筑中通常使用的，它们要么是膨胀合成橡胶，要么是膨胀聚乙烯。
Also available is a fiberglass sheath, that’s more commonly seen in commercial and institutional buildings than homes despite the fact that it offers a better coefficient of thermal insulation (near R-4).
If indoor air quality is a top priority for you, we would recommend you opt for the polyethylene foam insulation as it does not emit odors or VOCs. The synthetic rubber (or EPDM) sheaths can produce odors that adversely affect people who are extremely sensitive to chemicals. This information comes from Canada Mortgage and Housing Corporation (CMHC), despite the fact that this product is UV resistant and therefore acceptable for use outside, which is not the case of polyethylene.
Finally, almost all brands of fiberglass insulation contain a formaldehyde-based adhesive that can escape into the ambient air when the product is exposed to high humidity and high temperatures. The fiberglass sheath is characterized by a higher insulation coefficient, which can nevertheless be achieved by installing a larger diameter polyethylene foam sheath over a smaller sheath. You can wrap the sections still exposed to the insulation tape to complete the work.
Remember that cold water pipe insulation is also a good practice that prevents moisture condensation on the cold walls of the pipe, which protects nearby building materials from the risk of any water damage.
Hi,
I would like to ask, how long the composting heat were produced (weeks or month long?) Thank you!
Wow!! It does make a theoretical sense. So, how efficient is it? How long will the temperature be in the high ranges? Hot tubs are mainly used during the colder temperatures, and I don’t think the composite pit would be able heat up the water up till 60 °C. If it provides enough efficiency, then it saves a lot of cash in electricity bills. As of now, thebest way to save on electricity bills are by proper usage of hot tub coverswhen no one is using it.
“你的堆肥能维持多长时间来制造热水。这堆东西需要多久搅动一次?还有你有什么样的氧气导入方法。根据我的理解，堆肥要么要搅拌，要么要有备用的氧气来源。搅拌一堆管子一定很难受吧。
