I seem to have developed a difference in logic from most of the "experts" I have spoken to about hydronic radiator panel locations and I'm hoping that someone can set me straight!
We have picked ourselves up off the floor after the quotes came in for hydronic heating for our house in Melbourne and resigned ourselves to paying >$11,000 for the system (fully installed).
Both the architect and the suppliers that I have spoken to have recommended placing the panels underneath the windows - particularly in bedrooms. From a convenience perspective I get it because it is rare that you want to put furniture in front of the window, however from and energy efficiency perspective it seems flawed! Given that I am filling the external wall cavity with R2.5 batts (my eski theory for house insulation) why would you place the heater such that the convective heat passes in front of the part of the room that has the least insulation (R0.5 at best)? Add to that, we will probably add full length curtains that, when closed will quite nicely trap the heat between the window and the curtain!
Am I mad or should I rather locate the panels ideally against an internal wall away from the window so that the convective heat distrbutes through the room and the radiated heat does not get lost through an external wall?
