Hi
I have had a PowerMax HE 115 for about 8 years or so and it generally works fine. However, getting the radiators to behave in winter has been getting a bit more erratic each year. last year didn't get all that cold so gave up on the downstairs towel rail which refused to play ball.
This year I'd like to get them all working better! Colder this year they say!
Feels like, given enough time I should be able to do so.
I have been tweaking the lock shield valves on the rads altho two leak if fiddled with so have to leave those open (for now)
I can get 6 of the 8 rads working ok, not stunningly hot but ok however 2 of them won't then come on. If I switch off the good 6 the bad 2 come on just fine so they can work. Am guessing it is a order problem but not sure how to work out which are closest and follow the "balancing instructions" I can find on the web. All the rads bar one are fed from between the ground and first floors (boiler downstairs) so not really sure how the flow and return is arranged in the void.
I think with time and an infrared thermometer (that I am getting tmrw) I should be able to follow the process thru and get the valves set better.
What I would like to know is that my boiler is set to the right pump speed and that the isolating value is set?
I have thermostatic valves on all the rads so I think I should be on speed 3 and the valve open?
How do I check these? Can't find any online guidance for pump speed and don't want to open up the boiler until I know where I am going if that is what I need to do.
I think I read that the isolating valve is the eye valve front and centre of the boiler's mech and not to fiddle with it or it will leak (had that experience on the feed for the downstairs loo so very wary of those valves). Can I tell its setting visually? Am thinking it should be horizontal for "open"?
Great site by the way
Thanks
Simon
