I've combination fed both my kids due to not enough milk and this is what we did
We've used aptamil and we put the cooled boiled water in bottles ready to add powder as and when needed. My son wasn't fussy about what temp he had his bottles so we would put the full amount of water in the bottle and add milk powder as and when he wanted a feed so it was ready in seconds. We used tommee tippee bottles & powder dispensers and would just take them out so they were ready.
My daughter is a fussy madam and likes her milk hot so we currently put about 2oz boiled water in the bottles ready and we have the tommee tippee thermos flask which we fill with boiled water and use that to top up to 5oz when she needs a feed. It keeps water hot for ages - sometimes its cooled down quite a bit so we end up tipping out the 2oz and just using the water from the flask but thats usually after about 18hours or so. If we are only goingout for a couple of hours we'll put the full 5oz of not quite boiling hot water in the bottle and put it in a tommee tippee insulated carrier which keeps it quite warm for a while. If we will be longer than that and don't know if we can get the bottle warmed anywhere we just take the thermos with us.
