Hi, my family and I have used the above heater from new when we moved into the house 20 years. But for the past few months the water doesn't heat hot enough to do the washing up ( we put the kettle on ) and not really hot when showering. Someone said its because the water is so cold in the ground. But even on mild days it still doesn't get hot. Judt wondered if anyone had any ideas please ?
