Plumber or electrician to replace new timer switch Unvented cylinder

[Jan2238]

Replace the current E7 Newlec Economy control to a mechanical 24 hour timer switch for unvented cylinder water heater, may I know if I ask plumber or electrician to do this job.

Because Newlec Economy controller can heat up water once a day in midnight .I would require constant hot water in different time slot per day.

How to Make sure that Timer switch wire connects with bottom element instead of top element ( boost). As the boost can heat up 1/3 of tank water only.

Appreciate for any help or guidance. Thank you.

Spark but that timer you have chosen isn’t suitable for your setup

Hi Thank for your reply. May I know what type of timer switch will suit my Megaflo unvented water cylinder 120L.
