Questions we get asked
Is no heating after a power cut a controls fault or a boiler fault?
A programmer or timer that has reset to a default schedule or lost its clock
What normally puts no heating after a power cut right?
Most post-power-cut calls are resolved by controls rather than appliance repair.
Is it safe to keep using the system with no heating after a power cut?
If the boiler locks out again immediately after resetting, don't keep resetting it. Repeated resets on an ignition fault can be genuinely unsafe.
