As summers grow hotter and wildfire smoke affects local air quality, more GCEA members are considering heat pumps for efficient heating, cooling, and improved indoor air quality. Condo and townhome owners may wonder whether limited outdoor space or electrical capacity makes installation impractical. GCEA asked local contractors what is required when space and panel capacity are constrained.
LIMITED SPACE DOESN’T HAVE TO BE A BARRIER
Ray Alspach of Alspach Refrigeration says heat pumps can usually be added to condos. Because condos are often small, they typically need compact systems, including indoor units when outdoor installation is not possible.
In Mt. Crested Butte, many condos already use electric heat, so a heat pump often does not require a panel upgrade. The installer can size the system based on available panel capacity. Heat pumps and electric baseboards can work together when their thermostats are coordinated, so the more efficient heat pump provides primary heat, while the baseboards serve as a backup when needed.
CONSIDER ELECTRICAL CAPACITY
Nunatak Energy notes that adding large loads can be challenging for homes with less than 125-amp service, while 200-amp service is generally sufficient to add the load a heat pump requires.
Electricians can determine if the panel needs an upgrade to a larger service by evaluating actual demand in kilowatts. GCEA can provide members with 24-hour demand data upon request, which may help an electrician understand how much electrical capacity is being used throughout the day.
WHAT ABOUT SPACE IN THE ELECTRICAL PANEL?
Physical panel space is rarely a barrier. Installers have tools and equipment to work around services with lower capacities and to prevent circuit overloading.
Neither contractor has encountered a home where actual electrical demand made adding a heat pump or electric range impossible.
HELP IS AVAILABLE
If you are considering a heat pump for your condo or townhome, ask an installer to evaluate the available space and electrical capacity. GCEA rebates may help reduce installation costs, and the On-Bill Repayment program may help finance the project. Contact GCEA for eligibility requirements and next steps.
