isar HE30 - how to disable preheated hot water tank?

uk125 · 30 Dec 2023

Hi there,

I moved to London last year as due to work.

I have a house up north, it has an isar HE30 combi boiler, fitted by warmfront scheme 15 years ago. It has preheated hot water tank for instant hot water.

Since I moved to London, the boiler keeps the preheated tank hot all the time which is very wasteful to gas and bad for environmental. I looked in the manual, nothing say how to turn off/disable the preheated hot water tank?

HOW? I looked EVERYWHERE on net. Nothing!

How can I turn off the preheated hot water tank please?

Thank you
