循环辐射采暖是一个完整的家庭采暖解决方案吗?

我提议在我的底层安装循环辐射采暖系统，使它更上一层楼，因为我还计划安装一个无管道热泵系统。在进一步的研究中，我发现一个正确设计的辐射系统可以使热泵系统多余。
我想听听你的想法。
Radiant heatcan be a completeheating solutionfor a home, but to do so successfully there are considerations. Anyradiant floorheating system (gas or electric,hydronicorradiant air heating tubes) would need to besizedfor theheat load, and so it would need to be designed by anHVAC professional.
To understand the concept of radiant heating and its limitations, I’d start with this page here about home heating and comfortable home design -
Designing Homes for Human Comfort
To be sure I understand your question, is this a new home build or a renovation project? If you are looking to install a hydronic radiant floor on top of a subfloor that sounds like you have a foundation, is that correct? Radiant floor heat (as you will learn from the article above) only heats single floors at a time, so if you have a basement you’ll need some heat down there.
We have it ingrained in our heads that ‘heat rises’, which is, in a word, wrong. ‘Warm air’ rises, but heat goes in any and all directions. With a forced-air heating system, some heat will find its way to the upper floors, but that’s not really the case with radiant heating, instead it gets cooler the further you are from the source. So, the temperature at knee level will be warmer than at your head level (not by much, but a bit).
So yes, radiant heat can heat an entire home when designed for it. And while a radiant system can provide the necessary heat for a home, it may require make-up heat on an HRV system to meet building code requirements depending on where you are. What is your climate zone or closest city /province / state?
Hi Mike,
非常感谢您的参与!我也在消化你那篇关于设计舒适住宅的优秀文章。我也在研究空气-水热泵的可行性，这样我就可以享受辐射供暖和制冷。回答你的问题，两个答案都是肯定的。这是一个在地板托梁之间隔热的基础上的新建筑。我计划把管道安装在底楼上面，而不是下面。此外，还将安装HRV。
I live in Bellingham, 98229 WA and being in a "frost pocket" we are more a 5B or 5A.
Thanks once again!
欢迎你杰里米!We did a combination of radiant floors, air source heat pump and heat pump water heater in ourEdelweiss House(not to mention passive heating), and while some may think it to be overkill, we like the idea of a backup heat source.
We use the radiant floor mostly for comfort, to keep it warm enough to walk comfortably on it but we rely on the heat pump as the primary heat source because it is about 3 times more efficient. We can do that because it's a small, open concept house with good circulation and an airtight envelope. The heat pump is a small ductless unit in the living room but pretty much serves the whole house.
那么它是多余的吗?嗯…有一点，但也有一点。)当一间房子没有流失太多的热量，你就不需要增加太多的热量。我不会建造一个“符合标准”质量的房子，在那里我需要降低15K来满足热泵系统和辐射地板的需求，但那个房子的热负荷很小，我们只需要安装3K(加拿大元)，而且效果很好。
