As I use lpg to heat my boiler the drain is on the side which does leave a few litres left so I just put a hose in the boiler and let gravity do it's thing to fill as it's draining until the water is nice and clear. Then when it's finally drained to the point of stopping the flow there is only water left in the boiler then before refilling I just use my my Vax to suck out the water after giving the boiler inside a good clean with the water in the bottom.
