Nothing is more critical than the thermostat when maintaining a comfortable temperature in your homes. You won’t be able to enjoy the benefits of the most advanced heat pump system to the fullest without the right thermostat.
If you have a heat pump or any other heating system, you will need to get a compatible thermostat explicitly made for it. There are two types of thermostats available today: on-off and programmable. On-off thermostats are basic models that switch the heater on when it falls below a certain temperature threshold and vice versa. Programmable thermostats are more advanced devices that allow users to set different temperatures at different times of the day.
In this article, we will focus on the review of thermostats. Let’s take a look at our top picks and some of each’s pros and cons!
Heat Pump Function
A heat pump is a device that transfers thermal energy from a hot location to a cold location, using a minimal amount of external power. Heat pumps move thermal energy in the opposite direction of spontaneous heat flow by taking heat away from a cold environment and transferring it to a hot location.
The function of a heat pump is to move thermal energy from a lower temperature to a higher temperature. The heat pump must first absorb the heat from the lower temperature source and then release it to the higher temperature sink. It uses a small amount of external power to accomplish this work.
The heat pump is an efficient way to transfer heat energy from one area to another. It is so efficient that it can reverse the direction of heat flow and cool. When used for cooling, the heat pump transfers heat from the inside of a building to the outside. It is the same process used for heating but in reverse.
Thermostat for Heat Pumps
A thermostat for heat pumps is a device that controls the operation of the pump, regulating the temperature of the air or water in the system. The heat pump is usually located near and may integrate into the unit, or it may be a separate device. You may control the thermostat manually, or a controller may automatically regulate the heat pump’s operation.
A thermostat can adjust the temperature in a room by turning the heating or cooling system on and off intermittently (by sensing the current room temperature with the help of sensor-equipped thermostats). The heat pump thermostat turns the heat pump on and off to maintain the preferred room temperature constantly. It always saves energy usage and money in the long term by regulating the system effectively. A good thermostat will save you money and energy if you choose it correctly.
When buying a heat pump thermostat, the most important thing to remember is that not all thermostats are compatible with heat pumps. You must choose a thermostat that is compatible with your heat pump.
Choosing the Best Heat Pump Thermostat
If you are looking for a new heat pump thermostat, there are a few things you should keep in mind. There are many different brands to choose from, so it is essential to research the right one for you.
Compatibility
When selecting a thermostat, you must pay careful attention to ensure that the system is compatible with your heat pump. Some thermostat models do not support HVAC systems that use heat pumps. You must scrutinize the specifications before purchasing a thermostat.
Budget-Friendly
Choosing the right thermostat is dependent on what you want and how much you’re willing to spend. If you’ve already narrowed down your choices to a couple of heat pump thermostats, you’ll soon be choosing the characteristics you want and your budget. A smart heat pump thermostat (such as Nest, Ecobee, Honeywell Lyric, and others) includes high-end self-learning, automatic programming, wireless connectivity, mobile app control, geo-fencing, voice control, etc.
However, those features come at a cost. If budget is an issue, you can opt for an ordinary thermostat for heat pumps, which will do the job and maintain efficiency.
Emergency Heat
You may build an emergency heating system into a heat pump, and if so, you must select a thermostat that supports the same. Specific thermostat models support heat pumps, but they do not support aux/emergency heating systems. Therefore, if your heat pump has an aux heat feature, select a thermostat that supports heat pumps with auxiliary heating.
Heat pumps operate well with moderate temperatures but might take longer than usual to warm your rooms if the weather goes extreme, such as during a freezing winter. Some heat pumps are equipped with emergency heating to deal with such situations. Auxiliary heating quickly accomplishes the heating. It is not energy efficient and increases energy consumption. However, it is a quick and effective way to heat a room.
Wiring
Heat pump thermostats require unique wiring, so you must verify whether yours does before purchasing them. You may verify whether your desired thermostat supports heat pump wiring by consulting the manufacturer’s specs or checking the model number online.
Smart Thermostat for Heat Pumps
A smart thermostat for heat pumps is a device that helps to regulate the temperature in your home by using sensors to detect when the heat pump is on and off. It then automatically adjusts the temperature accordingly. It can help save energy and money by ensuring that your heat pump is only used when necessary. The following are some of the best smart thermostats for heat pumps:
Sensi Smart Thermostat for Heat Pumps
Emerson thermostats manufacture this thermostat, and it works with your existing wires. It has a simple and fast DIY installation procedure because it does not require a common wire (c-wire). Since it is compatible with most heating and cooling systems, it does not require a c-wire.
Ecobee 4 Heat Pump Smart Thermostat
[amazon fields=”B07NQT85FC” value=”thumb” image_size=”large”]
The Canadian firm Ecobee makes smart thermostats, especially for North America, and they’re good at it. The Ecobee 4 is a full-featured smart thermostat that includes heat pumps (4H/2C – 4 stages of heating and 2 stages of cooling) and heat pumps with auxiliary/emergency heating (2 stages of aux heating). Using accessories (common with heat pumps) like humidifiers, dehumidifiers, ventilators, ERVs, and HRVs, Ecobee 4 works with a wide range of heat pumps.
Nest E’s budget-friendly smart heat pump thermostat is similar to the Ecobee 4, but it has a shorter build and feature set. The model Ecobee 3 Lite, compatible with heat pumps (Y1 and Y2) and heat pumps with aux heating (W1 and W2), is available at a reduced price.

They both support multi-stage heat pumps, and they both support up to two heating stages for auxiliary heating. They are both WiFi-enabled and work well with heat pump systems.
Nest 3rd generation thermostats turn on auxiliary heating when required (only when the outside temperature falls below the lockout temperature). Nest automatically activates a heat pump balance and determines the lockout temperature for auxiliary heating.
If you’re unfamiliar with Nest’s self-programming thermostats, it automatically configures itself based on your daily routines. Nest thermostats usually take 7 to 10 days to learn your way after installation and self-program themselves for optimal energy saving. The Nest E is a budget-friendly heat pump thermostat that works with heat pumps and aux/emergency heating. Our post described the differences between Nest E and Nest 3rd Gen. You can use this thermostat as a WiFi heat pump because it is WiFi-enabled.
If you look at the back of the thermostat, you will see O/B and AUX/E (O/B and AUX/E) labels. The thermostat is compatible with heat pumps (O/B) and aux/emergency heat pumps (AUX/E). It’s a straightforward way to verify if a thermostat model is compatible with heat pumps by examining its wiring labels. You can tell if a thermostat is compatible with heat pumps by looking for two identifiers: O/B for heat pump compatibility and AUX/E for auxiliary heating compatibility.

The 5-1-1 thermostat is the last option for those who have different schedules for five workdays and two weekends.
Saves energy bills: Using a thermostat correctly can help you save money on your electrical bills. You may use a thermostat’s programmable function to control the temperature, turn on and off your household appliances, and save money on your electricity bills. For example, you may turn off your air conditioner without being home. You can turn it off simply by pressing a button on the thermostat. They will automatically adjust your home temperature when you are asleep.
Precise, controlled temperature: According to the Air Conditioning Contracts of America, an analog thermostat will be less accurate than a programmable variety. According to the study, a thermostat with an analog setup would be off by up to 5 degrees Celsius. On the other hand, a programmable thermostat would be off by 1 degree Celsius. They’re more precise than analog thermostats. You’re certainly consuming more energy than you should, so you’re receiving extra electricity bills.
You don’t realize that you don’t know the proper temperature for your residence. You can’t disagree with me, can you? It won’t take much time to make you some money.
Enhance the efficiency of your home: Your house will be more efficient throughout the entire year if you use a thermostat. Your systems will last longer because you will effectively use them. You will also be able to relax and be comfortable due to today’s advanced thermostats.
Controlling the motion, light sensors, and humidity: An occupancy-based thermostat will adjust the temperature based on the amount of light or movement inside a home. Dehumidifiers and humidifier thermostats automatically keep humidity levels within a comfortable range, whether it is summer or winter, by adjusting the temperature based on the amount of light or motion within a room.
The humidity level must remain between 30% and 50%. You may experience allergies and asthma if the humidity level is outside this range. You may experience damage to the structure of your house, including the development of mildew and rot.
Conclusion
When choosing a thermostat, compatibility with your current HVAC system is essential. Some thermostats can be purchased in-store, while others are only available online. For the most comprehensive selection of models and pricing, it’s best to visit an online retailer. If you’re not sure of what type of system you have, take a picture of your existing thermostat and do a quick search for it online. An introductory service call from your HVAC repair company should determine full compatibility. You can locate all the information you need by consulting your owner’s manual.
