THROUGH-THE-WALL AC BUYING GUIDE

230-volt through-the-wall air conditioners with electric heat

Compare 230 V electric-heat profiles and check heating output, power and sleeve requirements.

Electric resistance heat and heat-pump operation are different choices. This page covers documented 230 V electric-resistance models, not a calculation of your heating load.
Find my AC →See 8 documented profiles ↓

8 profiles document 230 V operation and electric resistance heat. Your room and electrical installation still need checking.

In this guide

Choose the heating type deliberately

Electric resistance heat is a distinct model feature. A heat-pump model or a cooling-only model should not be silently grouped into this electric-heat shortlist. Confirm the full model suffix: similarly named cooling and heating variants can have different plugs, protection and capacities. Manufacturer specifications describe output; they do not establish the room’s heat loss.

Source 1Source 5Source 51Source 52

Check the heating electrical requirements

Read both cooling and heating instructions for the exact delivered unit. The cooling running current is not a circuit-protection rating, and the receptacle marking is not proof of actual supply. Current LG R32 heat-model cord drawings and outlet instructions disagree in the reviewed manual; that plug detail stays disputed pending clarification.

230 V and 208 V are separate

A nominal 230 V specification does not by itself establish 208 V operation or its performance. Where the manufacturer supplies a separate 208 V operating point, the finder uses it. It does not copy the 230 V capacity, efficiency or heating output into a missing 208 V field. If your building has 208 V, choose that actual supply in the finder.

Source 3Source 14Source 51Source 52

Size cooling and heating separately

The ENERGY STAR room-AC estimate addresses cooling. Do not reuse it as a winter heating-load calculation. Ask for a heating assessment where the unit is expected to provide room heat; then compare exact rated heating output and installation limits. The profiles below are a way to collect the right specifications for that assessment.

Source 1Source 5Source 107

Check the sleeve and included parts

A heating feature does not change an unsupported sleeve association into a fit. Start with the exact native sleeve for a new installation or a reviewed retained-sleeve procedure. Confirm the rear grille, trim and seals, and whether required components are included. The finder starts with 230 V and electric heat selected but still asks for your remaining requirements.

8 profiles with the requirement documented

Updated from the reviewed catalog: 8 document 230 V operation and electric resistance heat; 0 need verification of that requirement. Your room, actual supply, sleeve and required parts still need confirmation. This is not a ranking or installation approval.
