After another 6 days withÂ* no heating ..... boiler repaired under

Its now 22 years old.
Its a 30kW Heat only wall mounted gas condensing boiler - connected to a
pressurised thermal store.

I need a standard/Heat only ..... can't use as system boiler (as thermal
store control need to manage pump)


Want to replace with 'similar' .... I did like idea of Vaillant boilers
with SS heat exchangers - but only offer these in System boilers.

They do the 400 series heating only models (mostly open vented, but some
also suitable for sealed system).

The newer ones seem to be Ali HX though.

Couple of heatings guys advised that current range of Baxi is now vastly
improved ..... so could use Baxi Heat 800
Though only with aluminium heat exchanger (but with 10 yr warranty)

I did ask on another forum .. the answer there is to use the Dutch
boilers by Intergas, but there are no local Intergas approved installers
When I have asked British Gas/SSE and independent GasSafe guys they have
never come across one.

Thoughts on the Baxi Heat ?

No experience of them, so can't comment.

or other Heat only models to consider

Worcester Bosh have a few as well like the Greenstar 24Ri features
