I have a VCW Sine 18 T3, which apart from problems with the diaphram and diverter valve (both replaced in last year) has functioned pretty reliably for the last 6 years.
I recently had a system leak due to the failure of a section of plastic pipework (peeled open like a banana skin) installed by the previous owner. I replaced the failed section of pipe (with copper) and mopped up, refilled the system and bled the rads, and heat exchanger and cranked up the boiler. The system was not working properly after this, heating seemed to be overheating and hot water was tepid (max burn not being triggered). I ended up bleeding the pump and the system sprang into life and has been working okay ever since, until last night. I am away and the missus came home to an overheating boiler and tepid hot water. I instructed her to bleed the pump, which seemed to temporarily fix the problem, but it's back this morning. Boiler also seems to be losing pressure and requires refilling, although no obvious leaks. Any suggestions.
Is it repairable or does it need replacing?
