don't know if you have to ant but to cover yourself in case someone scalds themselves, put one on heater outlet, or maybe put labels saying ' caution, very hot water '

Isn't this asked on a risk assessment, the sink, i presume you mean for washing pots etc, needs to be above 50 to kill germs and clean items properly, where the basin, as in hand wash needs to be assessed, do at risk people have access, do young children have access, unsupervised, in which case a Tmv needs to be fitted close to the outlet, that's how we go about hot water in churches, community areas etc.
sink also needs signs stating that the water is very hot.

Spot on Stani. Did a couple of jobs for an architect two years ago, a church and a community centre. Pot washing was labelled 'extremely hot water' etc and the basins had tmv's to prevent scalding.

Sinks should always be hot. Basins in care homes, schools and healthcare should be controlled by tmvs. Not sure about churches. Use common sense

Thermostatic Mixing Valves (TMV)

down the page is a selector chart to tell you when you have to install them and when it is advisable

And my best adivce is ALWAYS fit a TMV3
