Recently moved into a newly built house running a Vaillent EcoTech Plus 618 boiler. Is it right that the only setting on here is to control the rad temperature - the left button doesn't have a tap icon above it to set HW temp as the manual says it should?
There is a thermostat on the HW tank, so maybe it has been specifically deactivated on the boiler?
The reason for my concern is that there have been a couple of days where we've had no hot water in the morning. I did notice that if I turn up the thermostat on the HW tank until it clicks, the boiler comes on at full power, the temperature rises very quickly to 80C and then it shuts itself down displaying an hourglass icon - all within a minute.
Just wondering whether there's user error here, or whether the plumber needs calling back?
Thanks,
Mark
