I've got an Ideal Classic FF350 boiler, the timer is set to turn on the boiler in the morning for a few hours and again early evening.
Works fine during the summer just heats the hot water and during winter months, when it heats the water & radiators. However for a while now, including during the summer months, the boiler fires up even when the timer is set to off.
It fires up, for no apparent reason, both during the downtime in the day and at night. I've checked the manual and no mention of a frost stat being fitted
When its not on the programmed times it fires up for a about 30 seconds or so about every hour.
During the programmed times when you use hot water, as you would expect, the boiler fires up to heat the added cold water.
I've used hot water during the off periods and it doesn't fire up nor do the radiators get warm. Just seems to be random and at a total loss here.
I assume, apart from wasting gas, there is no major problem, but it is beginning to get on our nerves now as we hear the boiler fire up during the night.
Be grateful for any thoughts
