🔧 Real Job Situation
Customer calls saying:
“My heating was working yesterday but now none of the radiators are getting hot.”
Before touching anything, what are the **first 3 things you check?**
For me it’s usually:
1️⃣ System pressure
2️⃣ Is the pump running
3️⃣ Thermostat/programmer calling for heat
A lot of heating faults can be diagnosed in the first few minutes if you read the system properly.
Interested to hear how other apprentices approach this 👇
