Ours has a built-in condensate pump, it automatically pumps out when the float switch is lifted, and it can lift something like 3m or more. It's not Bosch, it's a subbed part used by them, so yes you can have a drain higher than the boiler. For this reason it has a check valve which has been a bit crap, but that's by the by. We also had a mare locating our boiler due to chimneys, boundaries etc. so we ended up with a floor-standing one which vents up the chimney. It has a vent duct that goes up to a terminus that replaces the chimney pot, and the space left over in the chimney draws the fresh air back down, it's a massive balanced flue.

Heating is not that straightforward, despite the fact there are a lot of monkeys out there selling their services. Also if you want efficiency, it needs a bit of work.
