Hot water cylinder temp

[Buckster]

Moved into a new house about a year ago

House has fairly standard heating/water with an indirect (Joule) hot water tank

Thermostat on front though is set to somewhere about 48c which seems quite low - was provided the commissioning paperwork and a temp in the 40s was hand written on there (can't remember exact value) so temp obviously deliberate

Will try and query with builders but any idea why would be set so low please ?

Because house was expected to not be lived in for a number of months and they set a bare minimum temp ?

Experience that the thermostat maybe under reads temp ?

Looked at manual and seems.to suggest a higher water temp

Water from taps and showers seem hot

Any ideas please ?

Thanks for replies this is the thermostat on the hot water tank itself and is separate to the immersion heater

It is indeed about 2/3 down maybe it is like you said just as it allows for the temperature delta top to bottom

I've looked at commissioning documentation

It says

'What is the hot water thermostat set temperature ?" Hand written in box is 44c

I'll post up some pics

Only asked as seemed low
