Heat Without Depending on the Grid

Heat Without Depending on the Grid

Grid outages hit hardest in January. When the power drops, electric heat stops — and so does your comfort. This ACiQ furnace runs on natural gas or propane, generating 88,000 BTUs of actual heat independent of the electrical grid. The blower requires only 115v on a 15-amp breaker, easily supported by a modest solar battery bank or generator during outages. At Off Grid Vault, every product we carry is vetted for real-world performance — this furnace is built-to-survive the conditions a remote cabin or homestead actually faces. Multi-positional installation means it fits your space, not the other way around.

18-Speed ECM Motor for Consistent Airflow

18-Speed ECM Motor for Consistent Airflow

The multi 18-speed constant torque ECM motor delivers up to 2,040 CFM at 1,050 RPM on a direct drive system. Unlike single-speed PSC motors that slam on at full blast, this ECM motor adjusts its output to match your heating demand, reducing temperature swings and noise. At 1 HP on 115v single-phase power, it draws minimal current — easily handled by your off-grid inverter or backup generator. This is field-tested technology that holds up in demanding installations where reliability is not optional, it is the minimum requirement.

Flexible Configuration for Any Install Layout

Flexible Configuration for Any Install Layout

Upflow, downflow, or horizontal — this furnace adapts to your mechanical room, crawlspace, or attic without forcing a costly rework of your existing ductwork. The 1/2-inch NPT gas connection and 13.6-inch WC maximum inlet pressure accommodate standard residential gas lines. Metal flue venting is required for this 80% AFUE unit, which keeps installation straightforward for any qualified HVAC technician. At 146 lbs, it is manageable for a two-person install. Natural gas ready out of the box, with an optional LP conversion kit for propane-powered homesteads running fully off-grid.

Compatibility Check

Confirm these conditions before ordering to ensure this furnace works for your installation.

  • Your home uses metal flue venting (PVC/plastic venting requires a 90%+ AFUE furnace)
  • You have 115V single-phase 60Hz electrical service at the install location
  • Installation site is not a mobile home unless approved modifications are made

110,000 BTU 80% AFUE Single Stage Multi-Positional Gas Furnace

The ACiQ 110,000 BTU 80% AFUE Single Stage Multi-Positional Gas Furnace is a cost-effective furnace model designed to deliver dependable comfort to your home. With basic efficiency, it provides sufficient heating output to maintain warmth even during the coldest months of the year. This unit features an input of 110,000 BTUs and an 80% AFUE (Annual Fuel Utilization Efficiency), resulting in an output of 88,000 BTUs. This means 80% of the fuel consumed is converted into usable heat, while the remaining 20% is lost through the flue and standard furnace operations. As with all 80% efficiency models, metal flue venting is required. If your home requires plastic/PVC venting, you’ll need a furnace with at least 90% efficiency. The 110,000 BTU 80% AFUE Single Stage Multi-Positional Gas Furnace is configured for natural gas out of the box but can be converted to propane using an optional LP kit. This unit is not Low NOx or Ultra Low NOx compliant and may be subject to additional fees if shipped to California.

This furnace offers excellent installation flexibility, as it supports upflow, downflow, or horizontal configurations. Its durable outer casing is built to handle wear and tear over the years, ensuring consistent home comfort throughout its life span. However, please note that this model is not approved for mobile home use without additional modifications.

Every ACiQ furnace is engineered to provide quiet, reliable operation year after year. The 110,000 BTU 80% AFUE Single Stage Multi-Positional Gas Furnaceincludes a whisper-quiet ECM blower fan, thicker sheet metal construction, and enhanced cabinet insulation for reduced operating noise. ACiQ units are designed to save you money both upfront and over time by lowering energy bills. Multi-speed or variable-speed ECM blowers come standard, and available upgrades such as two-stage heating, modulating burners, and secondary heat exchangers can further improve energy efficiency and home comfort. Built with premium components including an aluminized steel heat exchanger, this furnace is also backed by extended warranty options—10, 20, or lifetime on the heat exchanger with online registration.

This gas appliance must be installed by a trained and qualified technician. Incorrect installation of gas lines, flue connections, or venting can lead to serious injury or even death. By purchasing this unit, you confirm that a trained professional will be responsible for the installation. We are not liable for any personal injury or property damage resulting from improper installation or service. The individual performing the installation or maintenance assumes full responsibility for any associated risks. Please note that many local jurisdictions require a licensed professional to install this type of equipment.
