The efficiency of a mod/con boiler drops a bit with higher return water temperatures, so there is some interaction with system design here. Assuming the heat loss is accurate, I'd probably look at a Triangle Tube PTS60 or a Lochinvar WHN055 for that heating load. Proper indirect sizing depends on your use pattern and the boiler size.Get Price
