Hi
Getting to the end of my tether with our central heating system. Please help.
1. Boiler: Vaillant TURBOmax Pro/2 E
2. Recurrent problems with various radiators (with TRVs) not heating up ever since the system was installed two and a half years ago.
Heating engineer replaced valves on faulty radiators last summer because some of the radiators were belting out heat constantly through the summer even when set to zero (when we just wanted the towel rails to be heated). He also reattached metal spacer for full connection on the valves.
Problem recurred as soon as we started using the heating regularly again in late autumn. At this point we paid for the system to be drained and new Honeywell TRVs to be fitted to all radiators. (The heating engineer who did this job bemoaned TRVs and said that we should just get them all removed and have a wall thermostat installed. His company told him to do the job in the end.)
This worked for three months, but we went away for a four day break and when we returned the radiator in our bedroom (furthest from boiler) had stopped working. Since then this radiator has mostly not worked, but occasionally starts heating up again.
Called the heating engineer again (same guy who drained the system down 3 months ago) today. He said that if the pressure is below one isobar then there is probably air in the pipes and the system will need to be drained. This is clearly expensive, and not something I am happy to have done every three months!
Any ideas?! My cynical side feels like I'm being taken for a ride by the property care company, but don't really have the knowledge to know if I'm right.
