Remeha Avanta 28 combi

[halliards]

My first post on this forum! Any help much appreciated.
My Remeha Avanta has been in for about 18 months now and had been fine until recently. From first fire up in the morning, the boiler kicks in as usual and I can hear the pump running, but before rads reach temperature the boiler shuts down for a couple of minutes before re-starting. This cycle continues and the rads only stay warm even though the room stat is calling for heat. I've done the usual reset stuff and the boiler readout doesn't show up any faults. This next bit may be my imagination....after running the hot tap for a bit, I swear the problem rights itself! Certainly, by late in the day, rads are up to temperate and all's fine again....until the next morning!
P.S. I'm sure the boiler/pump/rad circuit are noisier than before. Any ideas anyone? It's driving me mad!!!

As it is only 18 months old it is still under warranty.

Call your installer back, let him have a look, then assuming it's nothing simple, let him book a warranty call with Broag

Sorry, it is not a case of being worth a try, it is 'WHAT YOU SHOULD EXPECT' with the boiler under warranty still

Sorted!
I apologise to my Remeha! It turned out to be the Towerstat wireless prog/sat. It has either developed a fault or is the victim of router interference.
I have removed it and re-installed the original timeclock along with a two wire roomstat; hey presto.....back to normal!
This may sound illogical, but the system is quiet again; maybe because the boiler runs up to temperature rather than 'hunting'.
Whatever was going on is now resolved!
