All Electric Heat Pump vs Dual Fuel (Gas backup) Heat Pump in Northern Colorado: Pros, Cons, and What to Choose

Hybrid System vs Heat Pump

Homeowners across Northern Colorado are upgrading their HVAC systems to Heat Pumps and asking the same question:

Should I go all electric Heat Pump or a gas back up (Dual Fuel) Heat Pump System?

With energy costs changing and more homeowners focused on environmental impacts, efficiency, comfort, and long-term value, heat pumps are becoming one of the most popular options in Fort Collins, Loveland, Windsor, Timnath, Wellington, Berthoud, Johnstown, Severance, and Greeley.

This guide breaks down the key differences between electric heat pumps vs dual fuel heat pumps, the pros and cons of each, and how to choose the best option for your home.

What Is a Heat Pump?

The common thread with both systems is the heat pump itself. A heat pump uses electricity to move refrigerant between the outdoor coil and indoor coil, absorbing heat from one space and releasing it to another. In Heating mode, it absorbs heat energy from the outside and releases that heat to the inside. In cooling mode it’s the opposite, absorbing heat energy from the inside and releasing it to the outside. Modern advances in technology allow this to happen at higher efficiency levels then ever before.

That means a heat pump can provide:

    • Heating in winter

    • Cooling in summer

Most heat pump systems do require a backup heat source, because at some point of outdoor temperature, the heat pump may not be able to absorb enough heat to move indoors to effectively heat the space, thus requiring some sort of back up heat. This is where the decision comes in, do I use resistive electric heat for back up or do I use another common source such as natural gas or propane?

All Electric Heat Pump vs Dual Fuel Heat Pump: The Main Difference

As stated above, most Heat Pump Systems will require a backup fuel source if and when the Heat Pump is not able to provide sufficient heat to the building. So, lets take a look at some pros and cons of choosing electricity as the back up source vs. gas furnace as the backup source.

Pros and Cons of All-Electric Heat Pumps

Pros of an all-electric heat pump with electric heat as back up

    1. With an all-electric heat pump system the back up heat is used as a supplement source layering in with the heat pump as needed, to maintain temperature setpoint without shutting off the heat pump.
    2. If you don’t have another fuel source available such as gas or LP this option provides a great, high efficiency option.
    3. Practical option for homeowners choosing to reduce reliance on fossil fuels

Cons of an all-electric heat pump

    1. Currently, electricity back up (or resistive electric) is far more expensive per BTU than fossil fuels, especially when you compare it to natural gas.
    2. Time of day billing can make running a heat pump, especially with electric as the back up considerably more expensive to operate.

Pros and Cons of Dual Fuel Heat Pumps with Gas Furnace as the back up

Pros of a dual fuel heat pump system

    1. Having the option of choosing Gas furnace or Electric Heat Pump as the primary source of heat allows for maximum flexibility as utility prices fluctuate to insure lowest cost of operation. Setpoints can be adjusted to tell the system when and at what outdoor temperature is the ideal time to heat with electric heat pump or when to rely on gas.
    2. Likely the most cost-effective operation available if set up properly.

Cons of a dual fuel heat pump

    1. The gas furnace and heat pump cannot run concurrently. It must choose one or the other. Unlike the electric back up option that layers in on top of the heat pump efforts, this system would need to shut down the heat pump to run on the gas furnace as the alternate fuel source.

What to know:

All Electric systems, while highly efficient, does not mean that they are the least expensive to operate. This may seem contradictory, but with gas prices where they are currently, you still get more BTUs per dollar from gas at lower temperatures.

Eliminating gas out of the equation completely will likely cost more in operation costs in most situations. Significant solar PV can be an exception.

What’s the Best Choice for Northern Colorado Homes?

There are many factors to take into consideration when choosing a heating system for your home.

    • Up front cost (considering rebates and incentives available)

    • Cost of operation

    • Impact on the environment

    • Availability of fuel sources

    • Return on investment

These are the most common things to think about when making your decision. A trained comfort consultant can help you navigate these things and help to design the perfect system that makes the most sense for your situation.

Important Questions Homeowners Should Ask about Heat Pumps:

Will an electric heat pump work in Northern Colorado winters?

Yes. A properly sized cold climate heat pump can perform very well in Northern Colorado. Many homeowners add backup heat for extra comfort during extreme cold snaps.

Do I need backup heat with a heat pump?

Often, yes. Backup heat helps your home stay comfortable during the coldest days. Backup can be natural gas, propane, or electric heat strips depending on your setup and goals.

Can I use propane with a heat pump?

Yes. Propane can be used as backup heat in a dual fuel heat pump system, especially for homes without natural gas service.

What matters most when choosing a heat pump?

First and foremost, choosing the right contractor is most important. The biggest factors are proper sizing, cold-weather capacity, ductwork airflow, and choosing the right backup heat strategy for your home.

Rebates and Savings:

Some homeowners may qualify for rebates or incentives that can reduce the cost of upgrading to a heat pump system. Rebates change over time and depend on the system type and eligibility.

FAQ’s: Electric Heat Pumps vs Dual Fuel Heat Pumps

What is the difference between an electric heat pump and a dual fuel heat pump?

An electric heat pump not only powers the heat pump but also uses electricity as the backup. A dual fuel heat pump uses a natural gas furnace to back up the heat pump. Dual fuel heat pumps are much more common in Northern Colorado homes.

Do heat pumps work below freezing?

Yes. Cold climate heat pumps are designed to provide heat at low temperatures, and backup heat can support the system during extreme cold snaps.

What is a dual fuel heat pump?

A dual fuel heat pump uses an electric heat pump for efficient heating most of the season and switches to gas for backup heat, usually natural gas or propane, when outdoor temperatures drop.

Can I pair a heat pump with propane?

Yes. A heat pump with propane backup is a common dual fuel option for homes without natural gas service.

Is a heat pump cheaper to run than natural gas heating?

It depends on your energy rates, insulation, solar power and outdoor temperatures.

Heat pumps are very efficient in mild and moderate weather, while natural gas may be more cost-effective during extreme cold depending on utility rates and time of day billing structures.
