I'm very happy with my new boiler 111w. Had a tiny glitch with installation when installer for some reason didn't want to turn OpenTherm on (gives full control of boiler water temperature too) via controller. Other than that installation was excellent, very friendly and tidy guys and did the job within 7-8 hours. We opted for Nest thermostat which we can control from the phone application from anywhere. Overall I'm very happy with boiler and installation.
