Vaillant ecoTEC 824 - simplest 30kW replacement?

ThisIsWeird

Hi.

Looking to replace a 13-year old 824 with a new combi as its location is being moved, so seems like a good time to also replace. The new boiler needs to be more powerful - 30kW (as against 24kW?) - as the mains supply will also be upgraded.

The old 824 has actually had its pipes shifted to the new location before the owner realised that it might make sense to replace with new at the same time, so ideally looking for the most direct swap possible. Plumbers are back on Tuesday, so looking for the easiest boiler swap to 30kW. Any 'Vaillant' folks on here who can point to a current model that'll slot directly in?

Cheers.

Oookkkaaaay, the most obvious replacement is the 831, but I can't tell if it's still available?

And then there's the ecoTEC pro 28. Anyone know about these? Piping the same?

Pretty sure pipes for most boilers share a common layout. Worst case is the plumber needs to make up a few short lengths to connect to the old plumbing.

Yes, it wouldn't be a major issue for any boiler, but the situation is that the old 824 has just been shifted to its new position, and this late decision to replace it will be met with giant sighs if the pipes need tweaking again. So, if the 831 still exists, it should be a straight swap. Or, the pro 28/30, if the pipes are in alignment?
