Have a solid fuel burner with a back boiler, just had it fitted

Customer Question

Have a solid fuel burner with a back boiler, just had it fitted and every time we light it it makes a really load banging sound ever 5 mins or so. The boiler runs 5 rads but system hasn't been used since we moved in two years ago, any ideas why it's making these noises?

Hi my name is Brian. This sounds like an airlock in the system causing the water to overheat in the back boiler. is there a pump on the system. if so try turning it up for a while to attempt to clear the air.
