Rheem FT Series RHBH-FT260 Condensing Gas Boiler
Installed price on hydronic work varies more by market, existing-system condition and contractor than by brand. Several products in this catalog explicitly recommend getting at least two contractor quotes for this reason.
260,000 BTU/h extension of Rheem's FT condensing boiler line, launched in June 2026 for large residential and light-commercial loads.
Our take
A real capacity extension, though most ordinary houses would be badly oversized with a boiler this large.
Best for
Very large hydronic loads validated by a room-by-room heat-loss calculation.
Watch out for
More capacity is not better: oversizing increases cycling and can erase a condensing boiler's efficiency advantage.
Model number check: no_public_price
F.W. Webb lists the exact model as an authorized distributor, but requires an account to order and does not expose a public price.

Before you buy this
Ask about turndown ratio, not just efficiency — a boiler that can't modulate down to your house's actual heat loss on a mild day short-cycles, and short-cycling is what wears a boiler out early. Confirm whether your radiators or baseboard were sized for the supply temperature this boiler will actually deliver. And ask for a heat-loss calculation instead of matching the old unit's output.
