This morning, our hot water was lukewarm. We've had this before when the immersion heater went, so we bought a new one and replaced it. A Plummer friend checked it and said it was all ok and we'd have hot water in an hour or two. But we don't! 😓 What else could it be? He's coming back tomorrow but I'm in dire need of a hot bath! X
Water pressure is fine. No, a 5 bed semi. Central heating is totally separate. Tank was replaced about 5 years ago. It's blue. This is about the 5th immersion heater in 10 years. It normally trips the circuit and we know straight away it's the immersion heater in the tank. This time though, the water was just cool. It didn't blow fuses or anything. We have a man here now who's flummoxed by it!
