MediumRoastSteam just read what it’s circled in your attachment. It says setting 4 is 53C. It looks like, to me, if the scale is proportional, that 55C is where the “star” is.
DavecUK Oh the reason for 55C is legionella, 55C Kills Listeria in about 2 hours, 60C to 65C kills it in 15 minutes…but really it’s not a risk to have 55 in a domestic environment. Especially if the tank is only 70% hot with a lower cooler layer…lower than 55 is probably not great.
Hot water
I checked the instruction for this boiler. It shows the hot water range is 40 to 70. If proportional, I am thinking the average mark up is 4.3C and 4 will be 58 and e js about 62?
I am wondering if 4 is enough for the hot waters to kill the bacteria. The hot water tank has a temperature control and is set at 55C.
Central Heating
The same scale would apply. I will drop this to 4 than the recommended 5 and see how it goes in the winter!
Please ignore the display. I briefly fired to check the boiler after changing Hive battery!
DavecUK Turn down the washing machine to 30C and always use a biological powder. Never ever use liquids or liquitabs….always use powder. Powder mixes better, contains bleach and thus you don’t get slimy remnants for bacteria growth leading to a smelly washing machine.
We wash a full load running at 30C for 20 mins for all daily wear once a week. They are hardly dirty. The only issue with the full load is the non-colour stuff. We wash one weekly cycle full load and the alternative week two loads of 30C and 20 mins each for colour and non-colour (mostly whites).
The powder is mostly non-bio and the conditioner is always diluted with water (50:50).
