Baxi Luna3 boiler runs out of hot water?
Afternoon, I have a Baxi Luna 3 Comfort Combi Unit, The boiler goes on when I open faucets or showers, But goes cold in about 5 minutes tops, Then takes forever to heat up again. Cant even take showers. The unit is 2 years old, I checked the heat exchanger and flushed it out just incase of scaling or slime. Some dirt but nothing to stop water flow. This has been a constant issue. Was a direct replacement with an old baxi unit due to hurricane sandy.
