There's lots of info spread across many threads here, but I thought it might be worth having a reference thread, with all of the info needed in one place.
So, for those using Evohome with Opentherm I wonder whether you'd be kind enough to comment with:
- Boiler make and model
- Boiler type (combi / system / open vent)
- Whether any additional boiler hardware was needed to enable OpenTherm
- How well it works, any niggles, etc.
- If you upgraded to this from an initial BDR91 install, have you noticed much difference to comfort or costs?
