Why are my radiators not getting hot?
We recently had our boiler serviced and condensate drainage upgrade and waste clear out. Everything has been working fine for several months, but when we’ve tried to use our heating something is going wrong. The boiler registers it as on, and the pipe coming out of the boiler heats up, but it isn’t reaching any of the radiators. Pressure is fine, hot water is still working fine and radiators have all been bled. Wondering if a valve has been left in the wrong position or it’s something I can fix, or whether we need to call the plumber?
Pics attached of the valves and pipes, plus front of the boiler. It’s fitted with a thermostat controlled via Tado, which also showed the heating as on, but we don’t have smart radiator devices or anything.
Edit: problem solved thanks everyone for your help! 🙏🏻🙏🏻
