Looking for new boiler

[sargan]

I have a house heated by Underfloor Heating ***. and the source is a Baxi Barcelona (set to 29KW), pumped primaries go direct to a pressurised Thermal Store.
Control to the boiler is simple - 240VAC supply when Thermal store calls for heat, boiler burn, modulation as it decides.
No timer or control on the Bolier other than the built-in 'temperature dial'

It's now close to 20 yrs old ***. and of late has been unreliable ***.. loads of cct boards, burner door, electrodes, burner, fan, heat exchanger, flue all been changed - some several times.

Time to look for a replacement ***.. welcome suggestions for a condensing heat-only boiler, wall mount, 30KW.

Tried Googling and the common choices are in order:
Valiant EcoTec
Viessman Vitodens
Worcester Greenstar RI

My question is in the post " welcome suggestions for a condensing heat-only boiler, wall mount, 30KW"

30kW sounds big for UF heating

Vaillant for me, EcoTec Plus range.

What’s your ufh load as it won’t be near 30kw would be surprised if it’s over 15kw tbh

Yeah but tbf he's heating a thermal store first, different kettle of fish.

Design recommendation comes out at 28kW ***.. to suit the Thermal Store ***
