in Gas Heating

I have Navien NCB-240/130H Installed. There is no code, Error, leakage or weird sound. Also hot water supply is great. I have In-floor heat in my triple garage which is set to 22 degree celsius but it does not go more than 14 degree. Through out the summer I had it set at 5 degree (Off). Now I crank it to 22 degree but no heat more than 14 degree.

Temp set for SH is 180 degree fahrenheit (Max)

I have changed the batteries on thermostat and it works well.

Is there any setting needs to be adjusted ???

    What is the outside temperature? I assume that you are measuring air temperature?

    What insulation is under the slab in the garage? Any? And for how long have you been running trying to get the temperature up?

    What is the return temperature from the slab?
