DavecUK Interesting and useful approach to energy and cost optimisations. Our approach is a bit different. Our hot water comes up for 30 mins for 2 of us in the morning. That’s all the hot water for the day unless my daughter is at home or have guests like my 83 years old MIL.
I don’t remember changing the settings on the cylinder and the boiler at all. Perhaps, there is an issue that requires attendance. Keeping the HW knob at 6 helped as the water was very hot after 30 mins. My wife didn’t say anything. I had switched the HW on for 15 mins to ensure the grany doesn’t complain.
Re-CH, it doesn’t come up until Nov. We usually set it at 18 for the winter between 7 am and 9 pm. It is set at 8 or 10 to avoid freezing of the pipes in the night.
But, this season. we had to bring it on at 18 since yesterday as MIL is continuously complaining! We don’t want her to fall sick until she flies home on the next Sat. After that, we will revert the CH to 15C unless we really have to. 🤣
We need to simplify the pipes. It’s too messy. Our thought why change it unless required. I don’t like Combi for the same reason. What about mega flow ? It is not worth it now as we are just 2 mostly and 3 for a few days a month.
