Explanation of a heat pump with auxiliary heat

Understanding how a heat pump system functions can help you to know which type of thermostat is the best option for your home.

A heat pump system uses some form of refrigerant to exchange the heat between the air and water in the heating and cooling systems. It works by using an evaporator coil on the indoor side of the unit, which extracts heat from the air, and a condenser coil on the outdoor side, which releases that heat into the air.

When forced air temperatures drop too low outside, a supplemental auxiliary heat source kicks in to supplement this energy exchange process. This back-up auxiliary source could be either electric heating strips or a backup gas furnace—all depending on what type of system was installed in your house.

Installing a thermostat specifically designed for a heat pump with auxiliary heating will ensure that your thermostat is able to activate both systems when needed to maintain a comfortable temperature setting inside your home and help you save money on energy bills down the road.

Factors to Consider When Choosing a Thermostat

Before you purchase a new thermostat, there are several important factors to consider. You should think about the type of heat pump you have, the type of auxiliary heat system, as well as its energy source (e.g. electricity). After that, you can decide which features are important to you in choosing a new thermostat.

Thermostats come with features such as programmability and voice activation that require additional setup. Additionally, thermostats feature both manual and automatic changeover settings for cool and heat pump modes, settings for both heating and cooling temperature limits and the ability to create custom schedules. Finally, you should make sure that your thermostat’s wiring matches your existing system’s wiring configuration before making a purchase.

When it comes to compatibility with heat pumps with auxiliary heat systems, there are some specific factors to keep in mind. Many models come equipped with standard 24-volt wiring configurations for both heating and cooling systems, but more advanced models may require higher voltage configurations such as 120 volts for larger systems or up to 500 milli-volts (mV) on larger systems running off dual energy sources (e.g., geothermal). Additionally, many advanced models have sensors that detect outdoor temperatures in order to adjust the settings accordingly or they may be equipped with multiple stages or multiple speeds on their motors so they can better regulate fluctuating temperatures when needed.

Before buying any thermostat model it is important to do research into what features each one offers so that you can find one that meets all of your needs while giving you maximum control over every aspect of your home heating and cooling system operations.
