The Optimum ECOSAVE is a mechanical 24-hour multi-tariff timeswitch for controlling 3kW electric immersion heater elements. It lets you heat your hot water during low-tariff (Economy 7 / night rate) periods rather than at peak rates, and gives you a manual boost when you need hot water outside the scheduled times.
Suitable for single, dual or twin immersion heater applications.
Boost function
An adjustable boost gives you 15, 30, 60 or 120 minutes of heating on demand during peak tariff periods, so you're not paying to keep a tank hot all day just in case.

Frequently Asked Questions
Q: Where can I buy an immersion heater timer in Ireland?
A: The Optimum ECOSAVE immersion and Economy 7 timer is available from Shamrock Electrical at shamrockelectrical.ie, with free delivery to every county in the Republic of Ireland from the first euro. You can also order for collection from our shop in Greenogue Business Park, Rathcoole, Co. Dublin, usually ready in 2 to 4 days.
Q: How does it save me money?
A: It heats your hot water during low-tariff night rate periods instead of at peak rates. On an Economy 7 or similar day/night meter that is a significantly cheaper unit price for the same tank of water.
Q: What if I need hot water outside the scheduled times?
A: Press the boost. You get 15, 30, 60 or 120 minutes of heating on demand, then it switches itself off, so you are not left paying to keep the tank hot all day.
Q: Do I need an electrician to install it?
A: Yes. It switches a 3kW immersion element, so it must be wired in by a registered electrician in accordance with I.S. 10101.
Q: Can it be fitted in a hot press or garage?
A: It is for dry rooms only, and must not be installed near motors, transformers or anything else producing inductive discharges. A dry hot press is normally fine, and your electrician will confirm the location.
Q: Does it lose its settings in a power cut?
A: No. The quartz movement has a 72 hour running reserve, so the time and programme are held for three days.
Q: Do you deliver across Ireland?
A: Yes. We deliver to every county in the Republic of Ireland, and you can also order for collection from our Rathcoole shop, usually ready in 2 to 4 days.
