Hi,
my problem is that every other day I have to "bleed" all my rads,most air/hydrogen comes from my bathroom rad a good 30-45 second release of air! other rads about a 3-5 seconds. when i do this the pressure falls from 1.5 bar to 0 bar,I refill the system (slowly) to 1.5 bar pressure but again 1-2 days later most rads are luke warm,bleeding and refilling the system sorts the problem but as above not for long!
whilst bleeding the system the water is black-is this nomal?
also,i have water and heating temp set to max-and rads set to 2-3 on thermostat is this effective or should rads be set to 5,and system temp turned down??
thans for any help given:D

Good morning: You have a dirty system...more info here http://www.fernox.com/?cccpage=break_down_guide&sub=2 OH sets our TRVs to 3, boiler stats toward maximum. NB Rad surfaces will become very hot and possible hazard to young children etc.

thanks for the info,seems you help everyone on here, lol.
so what should i do from here??0 -
Good afternoon: You could do a DIY flush either manually or with a powerflushing machine or get a plumber/heating engineer in to do it for you and rebalance your system/give your boiler a service...depends on how confident you feel about your abilities http://www.hss.com/g/51610/Central-Heating-Flusher.html Cost for getting a CORGI in to do the jobs will vary according to the size/type of your CH system and where you live. As an example, my OH does powerflushes/rebalances CH systems/service here in Kent for £300+ ( eg. typical 7 rad system with combi boiler).
