Hot water brown in colour

[brumylad]

any older hot water cylinder will have brown sediment in the bottom. check that with the hot water cylinder empty, the small heating expansion tank in the loft still contains water, this will check the integrity of the coil inside the hot water cylinder.

Good plan there from Brumylad - IF you can find a drain cock for your hot cylinder! It's certainly worth a try because there's nowhere else left for the brown stuff to be coming from.

PS: If you don't have a drain cock you'll have to syphon the water out. Once you have the tank empty you either clean it out or, if the coil leaks, replace it. Either way PUT A DRAIN COCK IN!

Will that be the same advice for a primatic boiler ,thats what i have,the water is clearing slightly.If the thermostat on the heating system was up to high would this cause any disturbance to either tanks ?

 

[kevplumb]

if its primatic you will only have one tank for the heating/hot water

I've got a feeling it's the thermostat,my heating only bursts into action when the dial is at zero .and the radiators are burning unusually high.thanks every one for your in put
