Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. First I’ll need some more info so I have a more complete picture of you situation.

Please describe the problem

Customer: replied 8 months ago.
Our radiant heat isn't working. First time we have needed since summer.
Customer: replied 8 months ago.
We have a combo system.
Customer: replied 8 months ago.
It's a prestige. I think the settings might not be set properly. I returned to factory reset. Still nothing.
Expert:  Rick replied 8 months ago.

I'm sorry but I'm not available for a phone call. If the system worked properly in the past it's highly unlikely the setting were/are the problem. How many thermostats do you have?

Customer: replied 8 months ago.
But hot water is working.
The thermostats all have the sign that they are heating. But the boiler isn't firing.
Expert:  Rick replied 8 months ago.

Do you have zone valves?

Expert:  Rick replied 8 months ago.

If you have zone valves they have to open then signal the boiler that they are open. If that doesn't happen you won't get heat.

Expert:  Rick replied 8 months ago.

If you can't answer my questions you'll probably have to call a pro to help you with this.

Customer: replied 8 months ago.
I think so
