Re: Vokera Boiler
Hi Folks,
The low-down:
Heatexchangers on boilers do go from time to time, I have a lot of Vokeras in my area and the heatexchangers in my opinion seem to be a weakpoint on the mynutes (again that is just my opinion)
As for anyone with water apparent under the boiler!
TURN IT OFF - ISLOTE FLOW AND RETURN UNDERNEATH NOW!
if you leave this situation to go on for any period of time you will completely screw your boiler, as well as changing the heat exchanger you run the rick of blowing your PCB board, damaging your insulation panels, your burner bar and damage to the boilers inner casing, gas valve, the lot!
As for the price of a full boiler change, €2000 region is reasonable assuming power flushing of entire system is included (make sure this is done!)
NOTE: you say your boiler is a 14SE (assume Mynute) so it will not be a combi, just a system boiler (cobi supplies instant hot water and you will have no copper tank in your hotpress)
As for systems losing water pressure, a couple of possible causes, if the boilers expansion vessel has lost 'air' pressure, it may need recharging, possibly your PRV on the boiler may be dripping (you will see this from the pipe outside of your boiler) and there is a few other possibilities, but all very fixable, but lastly, you may have a small waterleak somwhere in your system even under the concerete floor!
The Plumber: leaky sytems due to pressure vessel failure?
I assume you are taking about stuck PRVs after operating due to pressure vessel being under pressure?
Topping up your system water from time to time is fine, and your service technician SHOULD instruct you on this when there (I know I always do!)
but if you have to topup the water often it indictes a problem with your system and should be addressed, as adding new system water is also adding corrosive water! and will result in system failure in the end! not just boiler problems, your system will rust from the inside out
If anybody need info on servicemen in south dubin / north dublin / meath / louth / kildare / laois for oil or gas heating I have a good few guys I can recommend for service and repair of systems (have experienced and checked over all their work in the past)

Hope that lot helps somewhat, could nearly write a book as an answer to some questions (have to stop myself..lol)
