Water Tank Heater Temperature Control

[jimjim2991]

I've just ordered one of these: https://www.hennlich.bg/uploads/en_galmatherm.pdf

It heats the water in my tank up to 80C in about an hour and a half.

I'd like to be able to have some temperature control, so I can set at 50C, 60C, 70C etc. What's the simplest way of doing that?

Can't see it has any thermostatic control built in? doesn't mention it in the link.
So maybe 80c is what it just reaches before the losses match the input.
You could use a thermostatic switch to control the feed to the heater but you'd need to make sure the thermocouple was suitable for the environment the heaters used in.

stat and a contactor

If it reaches 80C in half an hour then chances are it will boil if left for longer. As above you'll need to use an electronic temperature controller or thermostat. What exactly is the application?

What's the hot water being used for?
