Hi all,
My boiler was kind of new & installed last year July, I know there's build-in frost protection.
Also, there's an old external frost protection (attached photo) that the engineer did not disconnect it when installed the new boiler. I wonder if I need to disconnect/get rid of the old external frost protection?
The reason I asked is, since the boiler has built-in frost protection already, it will prevent the boiler from being frozen. Also, as my boiler is installed in garage where has no heat there in winter. Last year in a very cold day, even after morning CH was on for two hours, after that the boiler started again to operate when timer off! i.e. when timer was off, the zone valve for HW opened, and boiler in action for nearly 4 hours as no heat in garage until middle day the temperature went up.
Recently as the weather is getting cold again, I don't want the boiler starts to operate when we all go out for work/school. Our CH set for 1hour in the early morning, but after that, the temperature outside can still be -5C or -6C which means in the garage the temperature will be very low---this will trigger the external frost protection into action---then the boiler will be on for HW (our external frost protection is connected to HW).
So, can I disconnect the external frost protection? This will no bad effect? With build-in frost protection is enough for boiler?
Thanks for your opinion!
