60 degrees is the minimum setting to kill off legionella bactaria.
Use a mixer tap to get the correct temp at your sink/bath end or a good old plug if you have a seperate hot and cold tap.
Remember, hot taps weren't designed to wash your hands under.

And using solar to heat your hot water is the greenest way to do it so you can feel all nice inside.

This website https://legionellacontrol.com/guidance/temperature-influences-legionella-growth/#:~:text=How do you kill legionella,more effective the kill rate. suggests that 50 C is sufficient to kill Legionalla if that temperature is maintained for a few hours but minutesa at 60 C will have the same effect.

If hot taps were once designed to produce water so hot that you could be scalded, these days we have the means to ensure that does not happen.  If you have to mix hot water with some cold water in order to use it, the safest way to do that is with a thermostatic mixing valve in the pipework before the hot tap.

I used the guidance I have to follow at work on my procedures, 60 degrees makes sure the job is done much more quickly as people have varying ways of heating water, I only heat my water for 30 mins twice a day so need the extra temp to be sure.

As stated there though if you're continually heating your tank then a slightly lower temp will suffice.

How does the iboost compare to the Myenergi Eddi? I woukd assume they are both virtually the same?

Your iboost will send power to the hot water cylinder immersion heater until its thermostat reaches its set temperature. What temperature is the immersion heater thermostat set to?  Your boiler will operate on a different unrelated thermostat.   

It was set at 65c, the max, I have turned it down to 60c

That sounds like the thermostat controlling your boiler. The immersion heater thermostat is a different and separate thing, as Reed_Richards mentioned.

Will adjust the temp in the boiler to 60c.

I have a large tree in my garden and have had a tree surgeon to cut back and remove alot of the leaves and some branches on the weekend so hoping to see an improvement in the generation.

Thanks, I have reduced the cyclinder themstat down to 60c, also had the boiler supply some heating this morning for 30 mins as it been cloudy recently but hoping now I won't need to turn on as frequently.

I don't agree it was a mistake to install the iboost. If the battery is satisfied it will take the edge off your water heating bills. Nothing wrong with that. Also - the best can be made out of how you use your power. Delay washes and dishwasher to be in the middle of the day but not overlapping each other. The iboost can divert any amount of spare energy to heat the water as long as the thermostat allows it. My 240litre tank needs about 9.6 kwh to heat from cold.

Lastly if you have two immersions, on one tank, the iboost should do the top one first. That should be designated htr1.

This is a kick in level issue. The iboost will wait for 100kw of generation but you battery will come in first. You can change the level the iboost cuts in at in the settings.

That's the cylinder thermostat. What's the immersion thermostat set to?

They are two different things. For the iboost to be effective, the immersion thermostat needs to be set significantly higher than the cylinder thermostat. (Unless you have your gas-fired water heating powered off all the time.)

I think by early September it will be clear that the iboost doesn't earn it's supper (in conjunction with a battery). It is nice to see the solar being used but this is a money saving forum and on that respect I can't see an iboost paying for itself.  Given the frequent reports of early iboost death on these forum even less likely.

If the tree was affecting your generation at this time of year then unless you have reduced its height substantially (to near level with the bottom of your panels) in winter the impact on generation will likely still be significant. Trees soon grow back and the lower the sun is in the sky the greater the impact of shading.
