Thermostatic mixer for hot water cylinder

Hi
I've got an Aga which heats the hot water as well but the water temperature can get too high. Can anyone offer advice about whether I should use a thermostatic mixer at the cylinder or at each hot tap? In some ways I would like to solve the problem at the cylinder but that might leave the water running cold for too long. BTW the cold water pressure is not very high as it is on a private water supply.

If a cylinder solution is recommended, any suggestions for which thermostatic mixers are suitable?
Thanks

yes. Header tank (cold) for cylinder is about 2.5m above cylinder outlet. Cold water feed to tap locations is about 5m above taps.

 

Are you suggesting tmv on the cylinder or each hot tap?
Thanks
