The Exalt Wall is Ideal Heating North America's wall-hung residential condensing boiler line: the 110, 155 and 199 MBH heat-only models, each rated 95% AFUE with an 8:1 turndown, a stainless steel fire-tube heat exchanger and the CTRLMax control system.
Series facts
95% AFUE on all three models per the official model table.
The Exalt Wall heat-only series is the residential wall-hung side of Ideal Heating North America's Exalt platform. Three models — 110, 155 and 199 MBH — are published in the official model table, all rated 95% AFUE with an 8:1 turndown ratio and a stainless steel fire-tube heat exchanger. Each model ships in a natural-gas or propane version (IDEX110S / IDEX110LP, IDEX155S / IDEX155LP, IDEX199S / IDEX199LP), and minimum input steps from 13,750 BTU on the 110 to 19,375 on the 155 and 24,875 on the 199.
The control platform is CTRLMax, which the manufacturer describes as an EZ setup system with a graphical display and plain-text troubleshooting rather than numeric codes, plus three configurable circulator outputs, outdoor reset, domestic hot water priority and an integrated cascade function for up to six Exalt solo boilers. The 3-in-1 universal vent adapter accepts PVC, polypropylene and stainless steel, with 3-inch vent runs up to 100 equivalent feet and, on the 110 and 155, 2-inch venting up to 28 feet.
For British Columbia homes the practical figures are the 8:1 turndown, the 88 lb (110) to 119 lb (199) wall-hung weights in a 21.75 x 26 x 16.5 inch cabinet, and a maximum central-heating flow temperature of 185°F (85°C). The series is documented by Ideal as a heating-only platform, so domestic hot water is handled separately — typically an indirect tank — or by the Exalt Wall Combi models in the same family.

Services for Ideal Heating boilers
The Exalt Wall heat-only models (110, 155, 199) heat the building only, with domestic hot water supplied separately — typically an indirect tank. The Exalt Wall Combi models (155, 199) add on-demand DHW through an integrated plate heat exchanger, with published draws of 4 to 5.3 GPM at a 70°F rise.
Yes. The manufacturer lists an integrated cascade function for up to six Exalt solo boilers, and publishes a cascade wiring engineering bulletin for the series. Cascade packages are configured in the field rather than sold as a factory rack.
The Exalt engineering submittals list 'ANSI Z21.13 and CSA 4.9 Boiler Standards Compliance', CSA 4.9 being the Canadian gas-fired boiler standard, but no explicit Canadian sales statement was found on the official pages checked on 2026-09-09, so Boilers.ca records canadianStatus as unknown.
