Late one again, so just a quick question. Combi boiler, 7/8 rads, shower/bath, very little washing up!  , two stories, but semi basement which the feed/return will run through, very low system demand ay mo, but that will change. Do I need a pump?

Rockies right Karl, a combi does not need a pump, it relys on the cold water pressure to push the hot around the house, the heating is pumped via the internal pump inside the boiler
