Will air heated floors work in a northern climate?
Hello everyone, first off thanks everyone for the great website and content. It is extremely helpful for someone like myself who is trying to gain knowledge/education about energy efficienct buildings.
We are starting to design a new home, which will be located in The Yukon, Canada. We are planning on building a insulated slab on grade, with in floor heating. We are looking to build around 1600-1800sqft.
我们有一处5英亩的房产，非常适合建一栋朝南的建筑。它有一个大的平地，已经有一个全新的3间卧室的化粪池和安装在农场服务的电力。我们倾向于棚顶设计，带独立车库。“Canmore East”住宅类似于我们的设计路线。
Hopefully I have painted a bit of a picture of our project. I have many questions, but I'll start things off with the slab. Can anyone tell me more about air heated slabs vs hydronic? I understand hydronic is able to carry more energy in the medium, but also like the idea of having a system that only has air moving through the slab.
I have followed the building project from EcoHome with the air heated slab, but was wondering if anyone had any reviews of the system a year after? Also, being located in The Yukon, I'm hesitant as I may have to foot the bill to have a representive of Legalett brought up for the approval process?
Much appreciated, Matt.
Hi Matt, we're happy to hear you’re finding what you need on the site. So about your first question, air heated floors are just as effective and reliable as hydronic radiant floors for heating your house.This page explains the differences well –
Air heated radiant floors vs hydronic, which is best?
我们很乐意帮助你解答所有的问题，最好把它们放在单独的线程中，以保持主题的连贯性，所以我们将从你的平板问题开始。你说的没错，空气不像水携带那么多热量，但它也不需要。循环地板会加热得更快一点，但真的没有必要上下转动它，所以这不是每天都会发生的事情。两者都可以保持均匀的热量水平，但空气地板实际上可以做得更好，因为当系统关闭时，由于水中的热量，它们不会超过温度。
Legalett slabs are a bit thicker at 8 inches rather than about 4, so there is more thermal mass for holding the heat over the course of a day, and just like hydronic systems it will top itself up as needed. The heaters are sized to provide the necessary heat for a given space in a given climate and the company takes care of that. You don’t need a rep to come visit your site, justgo here to get a quote on a legalett slab and air heated floor.
We don’t have data yet on thesolar air heated floor, but depending on your hours of available sunlight and how far north you are its hard to say if that’s really worth the investment for you rather than putting that investment perhaps into a heat pump instead to reduce energy consumption. Pop any follow up slab questions here, we’re happy to discuss.
