My company installed thousands of Alpha combi bolers I must say over the years we have had very little problems with them .

The big seller for me is the service company that fixes any problems are in Aberdeen they are quick and know what they are doing Aberdeen boiler services in the bridge of Don .
That's another point to take in if something goes wrong with the boiler who  does the breakdowns for them .
Peace of mind for me knowing the customer doesn't have to freeze for 3 days without heating especially the older generation because the back up is right next door.
I also know the lads which of course helps.
