Advice Needed for replacing boiler controller

Hi, hopefully got the right topic here. Based in the UK, I have a 2 loop hot water system. Heating is controlled by Netatmo, but the hot water is using a Honeywell st6100a timer (24 hour controller). Is it feasible that I can replace the Honeywell with an Aeotec Nano Switch controlled by HA? I’ve had it laying around for a couple of years, and thought this would work, but any thoughts otherwise would be appreciated.

You’ll need to check the power draw of the heater and make sure it doesn’t exceed the aoetec switch rating. Otherwise it would be fine.

I’m assuming the power draw is quite low, as heat is provided by the gas boiler (sorry, didn’t make that clear).
