Hi - a first time post for me. Our hot water is too hot! - I've turned the thermostat on the boiler down to min but it's still too hot - I think it's coming out of the tap at about 65degrees. The info inside the boiler says the max is 82degrees. The boiler's a Glow Worm hideaway. Is it likely to be a thermostat problem? Does anyone know what the recommended temp for hot tap water is? Thanks PS Don't worry fixing this is not something I'll be attempting myself!
