Thanks, are there any other materials to avoid, mortar for example.

Does cable deteriorate when in contact with expanding foam in the same way as if in contact with polystyrene? Are there any other materials which can cause similar damage? Thanks.

Understood regarding Corgi involvement. Everything else is by the book. Benchmark filled in and corgi notified. It seems I have been conned a little. Thanks for your comments.

Tony, I have paid in full, but I have all the fitters info (including his corgi number). Do Vokeras come with a 2yr guarantee?

I recently obtained a quote to have a Vokera Unica combi installed. I accepted the quote and had the work done whilst I was at work. When I got home the boiler turned out to be a Sabre 28 HE. After some investigation the Sabre and the Vokera seem similar (if not identical). Whilst it is clearly...

The probable DIY install and lack of paperwork swings it in favor of replacement. I assume no self respecting corgi fitter would check an installation and supply paperwork retrospectively?

My combi boiler is beyond economical repair. Could anyone please recommend a replacement make and model. The house is an average 3 bed semi. Reliability is a high priority above cost and efficiency. My heating engineer has recommended a Vokera compact. Many Thanks

Bearing in mind the apparent unreliability of these boilers I am considering replacing it ( the engineer who replaced the PCB advised this). The impression I am getting from the responses is that a combi boiler is not appropriate if you only want the boiler for CH and not for hot water. I would...

I don't know the GC number, yes it is a combi, the cold mains is not connected and I don't know what MI is.

The only supply is through the filling loop (currently disconnected)

Forgive my ignorance, what is the APS? The DHW is not connected, I have a multipoint too

My 2.5 year old Ravenheat rsf84et fires when I turn the room stat up. It burns for about half an hour and the radiators are hot. It then switches on and off fairly rapidly, 45 seconds on and approximately 2 minutes off. The radiators gradually cool down. This process will carries on until the...
