What's the uk.diy recommendation for combi boilers these days? Replacing a stupid French thing (Britony SE) that keeps randomly locking out on PCB errors. I replaced the PCB and it did about 8 months and started again. Ran a soldering iron over it (I suspect bloody lead-free joints) and got another month.
It is going to be replaced with maximum prejudice :-)
So, who's good and any good priced suppliers?
