A basic, surface‑mounted mechanical timer aimed at straightforward daily control of immersion heaters and similar resistive loads. It’s simple to install and programme, offers 15‑minute scheduling steps and a removable link for volt‑free or mains switching. Best where low cost, simplicity and proven mechanics matter; avoid it if you need sub‑15‑minute control, outdoor protection or to switch modern lighting without a contactor.

A compact, no‑frills digital timeswitch for immersion heaters and other resistive loads. The OP‑IHTDIGI offers 24‑hour and seven‑day programming with one‑minute resolution, volt‑free SPDT contacts and a handful of useful manual modes. It’s a practical choice where predictable, local timer control is required, but not for smart integration or high inductive loads.

A technically clear assessment of the OP‑ECOSAVE immersion heater timer: who it suits, how it fits into typical cylinder setups, what it can and cannot do, and sensible installation and ownership considerations for households on multi‑tariff supplies.
