Please can someone help. I am looking for some guidance on a new boiler I have had installed.
Originally I had a conventional open vented boiler on the first floor of the property and the feed and return went straight into 22mm pipe under the first floor floor. From that it branched off to
15mm f+r to 2 radiators in loft
15mm f+R to front bed and bath
15mm f+r to rear bed
15mm f +r to 2 extension beds + 2 rads in kitchen on ground floor (*)
15mm to 2 rads on ground floor (each of these legs then have a second (total 4)
I have now had a new boiler installed on the ground floor in the garage. Its a 24KW system boiler / sealed system and when it was installed they connected the 22mm feed and return to a T piece onto a 15mm pipe next to the last radiator down stairs. This left 22mm going into a T with 12 radiators in one direction and 1 in the other.
Initially they struggled to balance the system and some radiators did not heat up at all (* above) These have now been moved over to their own 15mm feed off the 22mm from the boiler but this still leaves a 22mm fed splitting between 2 x 15mm. 1 rad on 1 side, 10 on the other over 3 floors.
My question is, is this right. Should the feeds go back to the original 22mm f+r upstairs?
