Supplemental Heating Solutions for Homes with Hydronic Baseboard Heat

When temperatures drop, many homeowners with hydronic baseboard heating as their primary heat source find that certain areas of their home remain chilly. Whether it's a drafty bedroom, a sunroom that struggles to stay warm, or a basement that always feels a little too cool, supplemental heating can make all the difference.  

Instead of overworking your primary heating system and driving up energy costs, a targeted secondary heating strategy ensures that every room stays comfortable without unnecessary waste. 

What Is Supplemental Heating? 

Supplemental heating refers to additional heat sources used alongside a home’s main heating system to enhance warmth and improve energy efficiency. Rather than raising the thermostat for the entire home, supplemental heat allows you to target specific rooms or zones, ensuring personalized comfort while managing energy use effectively. 

Why Homeowners with Hydronic Baseboard Heat Use Supplemental Heating: 

  

• Addressing cold spots in certain rooms (e.g., basements, sunrooms, home offices)
• Lowering the central thermostat and heating only occupied spaces to save on energy costs 
• Enhancing comfort in hard-to-heat areas or rooms with poor insulation 
• Supporting the primary heating system during extreme cold spells 
• Providing warmth in home additions or rarely used rooms 

By incorporating strategic supplemental heating solutions, you can create a well-balanced home heating strategy that maximizes efficiency and comfort. 

  

Ideal Supplemental Heating Options for Homes with Hydronic Baseboard Heat 

While hydronic baseboard heating provides consistent, efficient warmth, supplementing it with additional heat sources can improve overall comfort. Here are the best options:   

1. Electric Baseboard Heaters 

Electric baseboard heaters are an excellent secondary heating source for homes already using hydronic baseboard heating. They provide targeted warmth in specific rooms without requiring any modifications to your existing system. 

Benefits: 

• Zone heating for specific areas 
• Energy-efficient when used strategically 
• No need for ductwork or additional installation complexity   

2. Infrared Heaters 

Infrared heaters provide direct, radiant heat that warms people and objects rather than heating the air. They are a great option for areas where quick, efficient supplemental heat is needed. 

Best for: 

• Home offices
• Drafty living rooms
• Garages and workshops   

3. Electric Fireplaces 

Electric fireplaces are both functional and stylish, offering supplemental heating with the added benefit of an inviting ambiance. 

Advantages: 

• Provides warmth without drying out the air
• Adds aesthetic appeal to any space
• Energy-efficient with adjustable heat settings 

4. Space Heaters (Ceramic or Oil-Filled) 

Modern space heaters are highly energy-efficient and offer targeted secondary heating for small, enclosed areas. Oil-filled heaters, in particular, provide consistent, long-lasting warmth. 

Best for: 

• Bedrooms
• Bathrooms
• Guest rooms 

5. Ductless Mini-Split Heat Pumps 

For homeowners looking for a more advanced supplemental heating solution, a ductless mini-split heat pump provides both heating and cooling capabilities. 

Key Features: 

• Energy-efficient operation
• Ideal for larger secondary heating needs
• Can be used year-round for temperature control 

Where to Use Supplemental Heating in a Home with Hydronic Baseboard Heat 

Supplemental heat works best in specific rooms that tend to remain colder than the rest of the house. Consider adding additional heating in:

• Basements – Often colder due to below-ground placement and poor insulation
• Sunrooms – Glass-heavy spaces struggle to retain heat in winter
• Home Offices – Stay warm during work hours without heating the entire home
• Guest Rooms – Keep rooms warm when in use without overtaxing your main system
• Garages & Workshops – Make these areas functional year-round without installing an entire HVAC system 

Maximizing Efficiency: Tips for Using Supplemental Heating Wisely 

To get the most out of your supplemental heat system, follow these expert tips: 

Use Smart Thermostats 

Pairing your supplemental heat sources with programmable or smart thermostats ensures you’re only using heat when and where you need it, preventing wasted energy. 

Keep Heaters Unobstructed 

Ensure baseboard heaters and space heaters have proper airflow by keeping them clear of furniture, drapes, and rugs.

Utilize Ceiling Fans 

Running ceiling fans in reverse mode helps circulate warm air throughout the room, making your supplemental heating more effective. 

Seal Drafts & Improve Insulation 

Prevent heat loss by sealing windows, doors, and other draft-prone areas to maximize the efficiency of both your primary and secondary heating sources.
