How long will the heat battery last?

If no hot water is drawn from a charged Thermino battery, it can hold a hot water charge for up to ten days.

A client of ours in Orkney has a 210ltr system and experienced a power cut meaning he was unable to recharge his battery.

He was able to maintain normal hot water function (daily shower, general hot water usage for shaving etc, and doing dishes) for three days before the water went cold.
