heated floors in different rooms

[socapots]

Hi all.
Just curious if any of you have different rooms heated to different temperatures using in floor heat in your shops.

If so. How was it accomplished? And how do you like it? Would you do anything different?


thanks for any information you guys can provide.

You can zone the system using flow control valves. I have to do it because of the different types of floors in my house ... actually it is more complicated since I need different temperatures.

The problem with trying to zone radiant is the slow response -- especially with concrete. If you wish to keep the areas at a constant different temperature -- that is easy. You can do it with flow control or temp control.

Much depends on the BTU's required.

Electric, floor heating. I have my rooms set to different temps with no issues. No flow control, or anything like that either.

I've got 3 different rooms in my shop. Office with Rads., Old shop with a water to air exchanger, and the "New" addition with in-floor.

I used a Taco 3 zone relay. Each room has it's own thermostat. When a thermostat calls for heat, it triggers that relay turning on that zone's pump and the boiler. When the thermostat is satisfied, the relay shuts off. Turning that zone's pump off and the boiler shuts down. It's really simple actually but it's not a fancy mod/con boiler. With outdoor resets and other bells and whistles, your boiler may be more complex.

Some days, like yesterday and today (high of -2), the boiler is pretty much on 24/7.

My system is three zone. My house is forced air over boiler, while the garage and basement are in floor, both with their own thermostats.

Thanks for the input guys.
It is appreciated.
An additional question.
For the different zones. How do you run the piping? I have read that when not using multiple zones the first run of the loop should be on the outermost parts of the pad.
When it comes to multiple zones, do you run your first loop around the edge of that zone?
