Great looking garage. I'm going to start a garage project this year. How well does the floor heat work with the water heater set at 90? Does it warm the whole garage? My plan is for a 24x30 with a second floor and I have been looking into radiant floor heat. Thanks. Dave
Yes, it heats the entire garage with no cold spots. Radiant heat warms the floor and is so much more comfortable than any other heat.
I run the temp just above the lowest setting which is around 100 degrees.
When it gets warmer out I have a manual ball valve between the supply and return lines. When it gets warmer I just open it some depending on temp.
Usually the indoor temp stays right around 68 degrees.
I wish the boiler was a little more efficient but for now it works okay. I think a 75-100 gallon would be more efficient.
If you're doing both floors with radiant you'll need a regular boiler for that.
