Hi.
Have an Ideal condensing boiler, water and central heating.
When heating is selected can take up to 15 minutes at times before it tries to ignite even when the boiler has not been on for 8 hours and the system is cold, when selecting hot water it always fires up straight away.
Have a Honeywell HCW80 wireless room stat, new batteries, and when I turn the stat up and the red light comes on on the stat, the boiler does not try to light for usually 5 - 15 minutes.
Programmer is a Honeywell ST9400C.
Any ideas appreciated as to why it should take this long to come on when heating is called for, used to fire up straight away.
Thanks.
