went out on a call last night changed a roomstat this was an isar water was barely lukewarm but you couldnt touch the plate hex in the boiler it was that hot no heat going down the heating so im assuming its a scaled plate not transfering the heat

Sounds like it Steve assuming correct gas rate, flow rate etc

Be rather amusing if it was. New boiler goes in and same thing happens!

cheery little soul arent you, but having proved that one wasnt an issue via another appliance the new intergas went in yesturday and I have a v happy little old lady waiting for a commissioning flush and rm stat swap as the one they left her before was a 7 day multiprogrammable heap that she couldnt even turn on or off manually.
