New Combi installation, 2 radiators working, one up one downstairs the rest are cold?

[bruvvamoff]

Hi all

Sorry if this question has been done to death but every case is different as they say.
I just had a combi installation (Ideal logic 35kw) and the hot water works fantastic but not the heating.
I turned it on for the first time this year and only 2 rads worked.
I went round and bled every rad and the pressure dropped and the boiler shut off.
So I opened the boiler valves to refill the system as instructed by the plumber and the boiler came back on but still only upstairs bedroom and downstairs hallway radiators work.
Now my plumber is on holiday.

Any ideas?

although its recommended to upgrade to a two piper a one pipe system normally works fine if balanced correctly and restrictive rad valves are not fitted.

Ive installed new oil boilers on a one piper with no issues. Cust too tight to upgrade.

Just done the same this week, but custard is wanting several rads moved/ removed. Only issue, 5 kids and divorced mother means crap everywhere and she is also extending upstairs and in her garage so its shambolic!!!

Plus the new ext boiler install was 2nd hand , so had to remove and transport that. Then she wanted her oil tank moved off a high plinth etc etc, how we achieved the move is
only for the arms🙂
