Even a Modulating gas boiler has the importance of a heat loss. You want to match the heat loss as close as possible on the high side so the low side goes lower on warmer days. Let's assume you have a heat loss of 60k. A 150k boiler will cover the heat loss. It turns down to 50k. But what about the 60% of the season you need less than 50k. Use an 80K that turns down to 30k and more fuel savings.
For more info on heat loss see
