Actually, a 'hole' to put the boiler in has some historical relevance. Some 60 years ago, at a Youth Club I used to go to, that's exactly how it was done in an ex Miner's Welfare building. There was a large cast iron sectional boiler, coke fired, which lived in a hole about 4' deep - it couldn't really be described as a cellar as it was open. The hole was big enough to get round the boiler and fire it. The main pipework was 4" with 1" connections to the cast iron radiators. The flow pipe went up to the attic and the return pipe went round the edge of the ground floor. Each radiator was connected between the two via a drop pipe. There was no pump, just gravity - thermosyphon strictly speaking - and a big header tank in the attic.
No, I wasn't a 16 year old anorak, we had a freeze one Winter and the boiler went out, so we had to do some repairs, under the eagle eye of a Civil Service Maintenance Fitter.
