Boiler was running for 45 minutes this morning, but hot water was nowhere near as hot as normal. Hot water tank was fairly hot at the top, but cold at the bottom. Is this normal or should whole tank be hot if no water is drawn from it?
Have a condensing boiler, Gloworm. Central heating is working fine. Thermostat on tank is set to correct temperature. Tank is at least 15-20 years old. Could sediment be forming at bottom of tank?
Any help please.
Thanks
