Customer Question

Hello Rick!
We have called out plumber but he never answered his phone! We have a falcon II boiler and the water in the shower keeps going hot and cold repeatedly. The burner boiler indicator light (and blue gas light inside) keeps going on and off every 30 seconds or so too. Do you know if there is anything we can do? Seems to have gotten worse since electricians were in when electricity was off a week or two ago.
Thank youuuu

Perhaps the plate heat exchanger is scaled up and the boiler is having trouble putting heat into the water.

Try turning down the hot water temperature or running the water faster to see if improves in the mean time
