Hi All,
My central heating system is nearly 13 yrs old now, worked fine for years, did a lot of DIY in house, including adding a radiator, CH drained down numerous times, over the last 7 years.
In the last 3 years I've had 2 new Heat Exhangers from Worcestor Bosch (called out their engineers).
First was because we had a leak in the Heat Exhanger. Within a year we started getting intermittent hot water which got gradually worse (shower going hot and cold, running a bath would end up with cold water). You could watch the flame going on and off roughly every 2 mins, sometime staying off for quite a while - thermal lockup(?) apparently.
Called in WB again who put in a new HE (paid for) which sorted the situation, but a few months later started getting intermittent hot water again, not as often but it's getting worse again. Would like to get it sorted before winter sets in proper.
The current HE is still under WB warranty. I'm sure they'll balme my CH system but I'll ring them to see what happens.
Either way I'm guessing I need to flush/clean the system. I've read this thread about flushing.
I'm wondering weather just adding a cleaner such as X800 into the system would clean it and solve the issue with the HE, then flush it and possibly add a magnetic cleaner device or do I need to get another new HE (possibly under guarantee from WB)?
any thoughts appreciated,
cheers
