Ductless split air conditioning units with heat pumps can be a viable alternative to oil-fired baseboard heating in certain situations. However, several factors should be considered when evaluating whether they can fully replace oil-fired baseboard heating in an entire house:
Heating Capacity: Ductless split systems with heat pumps are typically more efficient than oil-fired baseboard heating systems. However, it's important to ensure that the heat pump's capacity is sufficient to meet the heating requirements of the entire house. Factors such as climate, insulation levels, and the size of the living space will affect the heating capacity needed.
Zoning and Distribution: Ductless split systems provide individualized zoning capabilities, allowing you to control the temperature in specific rooms or areas independently. However, if your house has a significant number of rooms or multiple floors, you might need multiple indoor units to ensure adequate heating throughout the entire house.
Energy Efficiency: Ductless split systems with heat pumps are known for their energy efficiency, as they transfer heat from the outside air to the indoors. This efficiency can result in significant energy savings compared to oil-fired baseboard heating systems. However, it's essential to consider the local climate and the heat pump's performance at lower temperatures, as extreme cold conditions may reduce their efficiency and heating capacity.
Initial Investment and Installation: Installing ductless split systems requires professional installation, and the cost can vary depending on factors such as the number of indoor units, the complexity of the installation, and the brand/model chosen. It's important to consider the upfront investment required for replacing the entire oil-fired baseboard heating system with ductless split units.
Supplementary Heat Sources: Depending on the climate and the specific heating needs of your house, it may be necessary to have supplementary heat sources in place. This could include electric baseboard heaters or other heating options to ensure adequate warmth during extremely cold weather conditions when the heat pump's performance might be less efficient.
Before making a decision, it is recommended to consult with a heating and cooling professional or HVAC specialist who can assess your specific requirements, evaluate the feasibility of ductless split systems with heat pumps for your house, and provide personalized recommendations based on your needs and budget.
