18 months ago, my daughter moved to a block of flats built about 4 years ago.
HW and CH is via an Electroheat Amptec C900 electric boiler (fitted as standard, I believe). Hers is in a hallway cupboard linked to an Oso hotwater cylinder. Cylinder is about 4/5 feet tall with a red (expansion?) chamber fitted over it and a pressure clock which she says has always been set at 1.5 thingies as required. Honeywell programmer sits on wall just outside for timings.
Although it gives hot water to taps, the central heating side has been very erratic, often failing completely. The building management people offer no advice or repair contacts. She had different people out to fix it to no avail. The last heating engineer then fitted a new PCB into the Amptec box in Dec 2005, saying that the main PCB cables to the elements had ‘ burnt out’. £300+ paid for new PCB and £75 callout. This seemed to get it going again, but was still occasionally erratic. CH was not used during summer; now no CH when switched on. Hot water fine.
She says all supply switches are on. The Amptec unit has the Supply light illuminated, but the Call light which is supposed to flash does not light at switch on and there is no ‘whoosh’ sound . The Heat light does not come on. The alarm light has never illuminated. I don’t know how it’s pumped, but she says rads are all bled.
If it is the circuit board failed again, I guess the guy who fitted it should replace it under warranty. She can’t afford engineers to just experiment with parts at her expense without properly identifying the fault. Any suggestions?
Sorry, no photos until I visit later today. Looks like another £75 callout plus parts in prospect, but I’d welcome some advance advice if poss. Thanks all.
