Remodel- convector to radiant?

Al Letellier

Sure you can do that and should have no problems getting heat duringmost of the heating season. You probably won't need much more that 110-115 degrees or so with quicktrac, but what about those chilly spring and fall days when the rest of the house isn't heating? you could install a heat lamp or two to give that extra punch when you need it. A separate zone would allow you to use an floor sensor to warm the floor year round. Just depends on the level of comfort you want to live with.

Remodel- convetor to radiant

I have an existing hot water boiler system with cast iron convectors recessed in cabinets in the walls. The piping to the convectors are piped as a two pipe direct return system. The water temp is approximately 170. The supply and return piping in the basement is 2" steel reducing down to 3/4" going to each convector through out the house. The house is a two story and their is one tstat on the first floor that controls the entire system. The bathroom that is being renovated is on the second floor. The convector in this bathroom is the last one to come off of the supply return / piping.
The question is this: Instead of repiping the boiler and running a seperate zone back to the boiler, would it be possible to use the existing supply and return piping from the old convector piped with a mixing valve and independant circulator controlled by a tstat in the bathroom.The bathroom tstat would only control the radiant floor circulator not fire the boiler. Would I have enough stand by heat in the supply and return piping during a no heat call in the main house? The floor area of the bathroom is 44 sqft and the shower floor is 10sqft. I will be using quick track covered with 1/4" hardibacker and ceramic tile. Any and all input is greatly appreciated.
