How to Choose a Thermostat for a Heat Pump

No two thermostats are exactly alike. Here are some important factors you should consider before you purchase one to manage your heat pump’s output:


Some thermostats are compatible with heat pumps and some are not. Before you buy any thermostat, you must confirm with a sales representative or from reading the specifications that it will actually work with your HVAC appliances.

Compatibility With Auxiliary Heating

Heat pumps installed in climates with subfreezing wintertime temperatures usually include an auxiliary or emergency heating function. If you have such a model, you should be aware that not all heat pump-compatible products feature auxiliary heating modes. Needless to say, you should look for one that does.

Technological Sophistication

Do you want the simplicity and basic functioning offered by a mechanical thermostat, or its electronic equivalent? Or, do you want the ability to program your device ahead of time? And if it’s the latter, do you want to wireless internet access and remote programmability? Or, is programming from a touchscreen on the thermostat itself the only capability you require?

These are the questions you must keep in mind as you evaluate the possibilities. Generally speaking, the more features it has the more it will cost, and that is something to keep in mind as well.

Types of Thermostats for Heat Pumps

There are two basic categories of thermostats: mechanical (non-programmable) and electronic (programmable). The former was the standard in the HVAC industry for many years. But they’ve now been largely replaced by electronic thermostats with a much wider range of features.  

Mechanical thermostats require the user to switch the device on and pick a specific temperature setting. Once this is done, it will turn the heat pump on and off as often as necessary to reach and maintain that number. No programming options are available beyond the basic temperature setting, which must always be altered manually.

In contrast, electronic thermostats are programmable by the hour, day, or week. Within the programmable category, electronic thermostats are divided into those that are programmed exclusively by touch and those that come with WiFi compatibility. The latter can be programmed from anywhere in the world at any time, through the use of a downloadable mobile app. These types of devices are sometimes called smart thermostats, in recognition of their advanced digital capabilities.

Are All Thermostats the Same When It Comes to Heat Pumps?

Your choice for your heat pump will be determined by many factors. These may include:

  • Price
  • Appearance
  • Length of warranty
  • Programmability
  • WiFi accessibility
  • Installation requirements
  • Compatibility with other HVAC equipment (if you have more than just a heat pump)

The heat pump thermostats currently available on the market are a diverse lot. As you look more closely at the models reviewed here, and at others as well, you should make your own list of ‘pros’ and ‘cons’ (from your perspective) before you make a final decision. After all, you’re the one most qualified to identify the perfect product for you, your home, and your family.

Thermostats were once the height of simplicity. But the integration of digital technology has changed the game forever.


You may or may not want one with a high degree of programmability, or that can be controlled through a mobile app. But you shouldn’t avoid a more advanced model simply because you’ve never used one before. Even the smartest, most elegant, and most sophisticated thermostats can be easy to program and control, once you learn how to use them.

People Also Ask

What Is the Purpose of a Thermostat?

Thermostats regulate indoor temperatures by turning HVAC equipment on and off based on pre-selected temperature settings. Without a thermostat, the owner of a heat pump, furnace, or air conditioner would have to switch the appliance on and off manually.  

How Does a Thermostat Work?

A thermostat is a temperature measuring and maintenance device. It is connected to HVAC equipment by wiring. When temperatures depart from programmed targets, it will send out an electric signal that triggers heat pumps and other such appliances into action.

What Are the Symptoms of a Bad Thermostat?

The signs of a faltering thermostat include:

Heat pump sometimes refuses to start, even when temperatures are falling or rising.

The heat pump runs constantly and will not shut down.

New batteries don’t change outcomes.

Hot and cold spots appear in different parts of the home.

The device is unresponsive and will not start.

When a thermostat goes bad, it actually gives you an opportunity to upgrade to a superior, energy-efficient model.
