I had a whole new central heating system fitted in my house about 16 years ago (new boiler, pipes, radiators etc)
We had a Potterton Prima F50 boiler fitted and overall it has performed very well (even though we have NEVER had anyone in to maintain it, it just worked day after day.
It is now starting to "play up" (gas burner flame often wont come on, or goes off after a few minutes). Sometimes the boiler "sounds" as though it is working, but no flame.
Is it worth repairing, or is it about time to get a new one. I have no idea how long boilers are supposed to last.
Note also the "timer" (Danfoss FP15) next to it is also now playing up, the various buttons often do not work, and the "red light" will go out, but gently pressing the "box" brings it back on again.
