Hi,
We have a 3 year old Viessman Gas Boiler,situated outside.Just been serviced by a 'service engineer' from Bord Gais who went off leaving the water heating control at zero.I have put it at 31/2 which still isn't heating the water to a high enough temperature, and I'm not looking for scalding.Can anyone advise what is the correct or recommended level to set it at.I'm a tad suspicious as the water was heating fine before he arrived!! Thank you
