the boiler is firing up when I adjust the temp on the thermostat but none of the rads are heating up. The heating system hasn’t been used in about 7months. Do I need to bleed the system, or is it likely to be something else?

Turns out when the electrician installed the heatlink yesterday they didn’t reconnect the flame sensor. So i thought the boiler was working but it was just it attempting to ignite & fire up.
