I cant believe that its been over a year ago since I had this discussion
We are having panels for our hydronic heating and I should be able to tell everybody what it is like in about 2 weeks if we have a cold snap. All windows are double glazed so it should be interesting to see how the house design functions in containing heat. As for the installation of the hydronics, never have I come across such an obliging and professional company. I can highly recommend them as well...they were about 8k less for a better product than another quote we got, always shop around. We are also having grates upstairs that come out of the floor underneath the window. There are many other new options to choose from now as we didnt have alot of wall space upstairs.
Will report back soon....
