Hi all,
Currently when i set my back boiler controls to 'Hot water only', the radiators in the top half of the house (apart from the bathroom where the water cylinder is) come on. The radiators get warm very quickly - in a little over 20 minutes. However, the hot water takes 2 to 3 hours!!! and i reckon this is probably because the hot water is being diverted to the upstairs radiators.
I've read that an 'anti gravity valve' might prevent this problem (my system is gravity based). Would that be the best way to go, and do you reckon the hot water will then be available faster since the radiators won't be drawing it off?
Cheers.
