UFh throughout is a much better system than UFh on ground floor and rads on first floor..... because when using rads the heating source has to be mixed with cold water to actually cool the heating water before entering teh UFh system.... highly inefficient...
Well, presumably the OP is talking about UFH under upstairs wooden floors.
...laminate is recommended best for upstairs..
That's really useful: thanks!
We're planning hardwood floors throughout upstairs.
Do you have separate a timer for upstairs? I would have thought you'd only need it on for a couple of hours. If so, is this wastful (to keep cycling it on and off)?
From what I gather you are using gas as your heating source. I am using a Geo-thermal heat pump as my heat source. It is set to come on at night time (night rate ESB) and heats up all the water in the system to the required temp that it is set to. Not too sure if gas can be controled like this but UHF is based on the fact that concrete will hold the heat and release it through out the day. If during the day the temp in the house cools down too much the heat pump will kick-in to boast the temp in the system. The termostats open and close the valves on the manifold to let in or stop the flow of water in the system depending on the temp of the individual room.
I take it from your last post that you won't have a concrete based floor upstairs. If this is the case then UHF is not the way to go for upstairs. I don't know if you have already built your house but if not I would seriously think about putting in hollowcore if you really want UFH. Otherwise go with the thermostat controlled rads throughout the house (my limited knowledged opinion only)
