Is this normal behaviour for a combi when supplying hot water?
The burners light, it runs for about 15s, then the burners stop. 10s later it reignites, and the cycle continues. This is while supplying a shower two floors up. I'm guessing it's because there is insufficient pressure to give a big enough flow rate, so it's cutting out to manage heat. But is that right, and will it wear it out?
