shawn_15

I have a tekmar 260 control running off a burnham gas fired boiler. The min / max is 150 to 180 on it. I am installing radiant heat in a bathroom with wirsbo trac plates on tile. I am using a wirsbo setpoint 501s slab control. Can somebody reccomend a piping schematic or a control stragedy on piping this.the existing radiant that is there that I an removing is 1/2 heatway staple up running on a sparco mixing valve. They are using a aquaris control made by emerson swan model number hwsp33w/sb and it has been installed for nine years and has never worked right
