How Much Does Wall Heater Installation Cost? [2025 Data]

Wall heater installation costs average $980, with most homeowners spending between $400 and $1,500 on average for a new unit and professional installation. Prices vary based on heater type, unit size, and labor rates.

Wall Heater Installation Cost Factors

Several factors contribute to wall heater installation costs, including the size, type, and add-on features.

Wall Heater Size

Selecting the correct wall heater size affects both comfort and cost efficiency. Wall heaters are rated by wattage or BTU output, which determines how much heat they can provide. Small, medium, and large units are designed for different room sizes, and the installation cost changes with the heater’s capacity.

Small wall heaters are suitable for bedrooms or offices, while medium and large units can handle living rooms or open spaces. Oversizing a heater for a small room may waste energy and increase upfront costs, while an undersized heater will struggle to keep your space warm.

Wall Heater Type

The type of wall heater you choose directly impacts both your upfront and long-term costs. Electric wall heaters are popular for their simple installation and low maintenance, but may cost more to operate depending on electricity rates. Gas wall heaters are efficient for larger spaces but require proper venting and gas line installation.

There are further subcategories of wall heaters, such as hydronic, dual-fuel, vented, or ventless models. Dual-fuel and high-efficiency models offer advanced features and energy savings, but at a higher initial price. Vented heaters direct exhaust outside, increasing safety but also installation complexity and cost. Surface-mounted units are easier to install, while recessed models require more labor and wall modification.

Labor

Licensed HVAC technicians handle wall heater installation. Hourly rates range from $60 to $150, with minimum service fees between $75 and $150. Projects requiring gas line upgrades cost up to $820 more, and hiring an electrician for a new dedicated circuit averages from $570 to $1,000. 

Labor is more expensive in metropolitan areas, with higher permit costs and stricter codes. Rural locations may have lower labor rates, but travel fees could apply. Within your home, installing a wall heater in a living room or open space is straightforward, while basements, garages, or hard-to-reach areas may increase labor charges due to added complexity.

Other factors may further contribute to total labor costs, such as:

• Ventilation installation or modification

• Site preparation

• Post-installation cleanup and debris hauling

Permits

Most municipalities require permits for new wall heater installations, especially for gas units. Permit fees vary depending on the installation's specific needs and your location. Inspections are often mandatory, with additional fees for follow-up visits to ensure code compliance.

Features

Adding programmable thermostats, smart thermostats, or other features increases upfront costs. High-efficiency or smart models demand a higher initial investment but can reduce long-term energy expenses.

Ongoing Wall Heater Installation Costs

Beyond the base installation, there are other expenses that may impact your wall heater installation cost over time.

Operating Costs

Monthly or annual energy costs depend on the heater type, local energy rates, and usage habits. Electric wall heaters tend to cost more to operate in areas with high electricity prices, while gas models have lower ongoing costs but require regular inspection for safety. 

Maintenance

Routine maintenance, such as cleaning, filter changes, and safety inspections, helps prolong your wall heater’s lifespan. Common repairs, like replacing a thermostat or heating element, range from $100 to $300.

Wall Heater Installation Replacement vs. Repair

When your wall heater stops working, you’ll need to decide whether to repair or replace it. This choice has a big impact on your overall costs.

Wall heater repair costs range from $50 to $800, depending on the issue. Minor issues such as thermostat malfunctions or worn-out elements can be repaired. If your wall heater is old, inefficient, or has major failures, replacement is more cost-effective. Warranty coverage may also influence your decision—if parts are covered, repair makes sense. If repair costs exceed 50% of the replacement cost, it’s best to invest in a new unit for better efficiency and reliability.

DIY Wall Heater Installation vs. Hiring a Pro

Some homeowners consider handling wall heater installation themselves to save money, but the process involves more than mounting a unit to the wall. Electrical or gas connections, code compliance, and safety requirements make this a project where hiring a local HVAC technician delivers better results and greater peace of mind.

In addition to purchasing the wall heater, DIYers should expect to spend more on purchasing other necessary materials and tools, such as a drill, level, wiring equipment, and safety gear. On paper, you avoid labor fees, but the savings can shrink once you factor in tool purchases, permit costs, and potential delays from mistakes or rework.

Certified HVAC or electrical contractors bring specialized training, licensing, and the right equipment to complete the job safely and in compliance with local codes. A pro can finish the work in less time, troubleshoot unforeseen issues, and ensure connections are secure—whether they involve electrical wiring or gas lines. Professional installation also protects your warranty, reduces the risk of hazards like gas leaks or electrical fires, and prevents costly code violations. In many regions, regulations require a professional to complete the installation.

Does Wall Heater Installation Add Value to Your Home?

Wall heater installation can offer a solid return on investment, especially if you upgrade from an outdated or inefficient system. Installing a new wall heater can provide returns on your investment through improved energy efficiency, comfort, and home appeal. Energy-efficient models are particularly attractive to buyers.

New wall heaters can increase safety and ensure code compliance, especially for older homes. They enhance energy efficiency, reduce monthly bills, and improve year-round comfort. Modern features like smart controls and enhanced safety also boost long-term value. Aesthetic upgrades and integration with smart home systems can further increase your home’s appeal and functionality.

Tips to Reduce Wall Heater Installation Costs

Here are some ways to save on your wall heater installation costs to help maximize the value of your investment:

• Shop for energy-efficient models to lower long-term costs.

• Get multiple quotes from licensed professionals.

• Schedule installation during off-peak seasons for potential discounts.

• Handle old heater removal or site prep yourself, if safe.

• Choose standard models over custom or high-end units.

• Bundle installation with other home projects to save on labor.
