Hi, I've got no experience - I'm just a landlord, but stuck as to next step - any advice gratefully received, please?
Vaillant 824 Ecomax plus (12 y.o.) in airing cupboard with Danfoss programmer. Honeywell T6360 wired stat was located nearby on landing - small 2 bdrm house with 4 rads ( 3 TRV's) - open plan lounge/hall/open staircase.
Previous tenant was having to repressurise about 6 times p.a. so regular Engr. installed a 12 ltr. red Eres Expansion vessel last summer, since when, the pressure's veered between 2.6-2.9 bars! (despite me getting him back to drain system).
Current tenant reported rads not heating up unless stat set at 23-30 and them immediately cutting out/not getting up to temp. even when he bought a thermometer and downstairs read just 15 degrees.
Got another Engr. in - he reset "click" on stat to 16; he also drained water from one rad - but this hasn't lowered high water pressure reading.
Got Electrician in who tested stat as working - and resited it to cold point downstairs, halfway along inner staircase, around corner from lounge rad.
Problem still exists so tenant's rightfully not happy. Any suggestions gratefully received. Thanks in advance.
