Hi
I have a gravity fed system. Standard boiler downstairs, hot water cylinder in first floor, cold water tank in loft.
I want to understand how to control the temperature of the water used for different purposes. The boiler has a dial (no temperature settings just dial min 1 2 .. max), the cylinder has a thermostat about 1/4th height from the floor.
This thermostat was at 50 and I just put it a 60 after reading recommended values. Where is this water going? Surely the taps and shower, what about the radiators? There is a pump in the cylinder cupboard which I guess pumps water to the radiators but my question is: does it take it from the HW cylinder or from the boiler?
The pump started to make noises yesterday all of a sudden.. kind of like "sucking water from the loft" noise so I could hear noises there too. Not rattling but annoying, as well as a few gurgling noises in the pipes below the pump. It was set to III (45w) I changed it to II roughly 11w and it's better now. Radiators are still hot today so that should be enough.
The cupboard for the cylinder also has two white boxes with a metal lever currently set to "MAN", the other option being "AUTO". No idea what these are.
Finally there is an old dial timer in the cupboard with two controls one for HW and one for CH. They can be programmed/set to constant independently.
Should I control the water temperature for central heating from the boiler itself?
Also our bathroom sink tap has a perfectly nice mix of hot/cold in the mixer tap. Will raising from 50 to 60 alter this much? My kitchen tap is super hot (almost scalding) with 50, so I mix it with cold but it's a separate tap.. kind of annoying and still a bit scalding. Would imagine it goes even worse after putting the cylinder on 60.
Sorry for all the silly questions I really want to understand this since I lived all my life with a combi boiler.
