Well yes but i should not have had to do it all in 1st place , i still have No copy of there Calcs using Mear , but i will go with my gut feeling and as the new rads almost match Stars Im Happy , sometimes when in a fight ya have to know when not to insist on knowing who was correct
They balanced my Rads using a proper set up it made almost no effect on flow and return , but unless im going mad the whole flat feels more even now Not hotter just beitter
Even tho the boiler is fully automatic range rating it has def helped in flow and retrurn and way system works , ok it takes a bit longer for rads to be red hot but it def seams to hold a better range on flow and return temps and once you up to temp the whole system seams to work better and heats up more evenly
It will be very interesting to see if new rads will get me a 75/55 flow and return , i kind of think it wont the drop i would need in return even with correct rads i cant see that happening , but i think i may not have to run flow at 75 with new rads
I will post my results after new rads are fitted , they will also carry out a new flush of system and a new balance and a full service
One thing i noticed theres a lot of confusion on this flow and return temp on a lot of sites , in uk im told we work on 11c which is 20F and in europe the setting are different , but everyone only quotes C
but from what i can tell the temps of flow and return under boiler are def 2-3c under what the read out shows on d40 and d41 and after speaking to valinat Tec and they train there installers to use the read out only ,If i was a heating installer i would take time to record the actual flow and return
the real end to this will be my readings after new rads fitted and how system works in real life
Ps the new rads are a 25% upgrade on Mears calcs , as they still maintain mears was correct
Facts are using Mear i was cold
