What size and type of heat pump is needed for 350 square foot house?

The size and type of heat pump needed for a 350 square foot house depends on several factors, including the climate in which the house is located, the level of insulation in the house, and the desired level of comfort. As a general guideline, a 12,000 BTU heat pump is suitable for a 350 square foot house in a moderate climate. However, if the house is located in a cold climate, a larger heat pump may be necessary. If the house is well-insulated, a smaller heat pump may be sufficient.

In terms of type, there are two main types of heat pumps: air-source heat pumps and geothermal heat pumps. Air-source heat pumps are the most common type and use the outside air as a heat source. Geothermal heat pumps use the earth as a heat source. Geothermal heat pumps are more efficient than air-source heat pumps, but they are also more expensive to install.

Ultimately, the best way to determine the size and type of heat pump needed for a 350 square foot house is to consult with a heating and cooling contractor.
