Heat Pump Thermostat – Guide to Buy The Right Thermostat

One of the common appliances found in US homes is the air-conditioner. They provide cooling during the hot summers. However, during winters when you need warm and cosy indoors, heaters are installed. This means, you need two different appliances for heating and cooling purpose. There is an alternative to all of these, the heat pump. Its versatile nature can be used for cooling, heating and dehumidifying. The working principle of a heat pump is same as that of the refrigerator. In simple words, it makes the cool place cooler and hot place hotter, by pumping out the heat from the colder area to hotter area. Therefore, during winters when it is cold outside and warm inside, it pumps out the heat from cool outdoors to warm indoors, making your place cosy and warm. Similarly, during summers, when it is warm outside and cold inside, it will pump out the heat from cool indoors to warm outdoors making your place nice and cooler.

These heat pumps use air, water or ground as a medium to pump out the heat. According to this they are classified as air source, water source and geothermal heat pumps. Out of these, most common is the air source heat pump.

Compared to electric baseboard and furnaces, these heat pumps offer better efficiency in terms of electricity use, as they don’t use resistance heating. Also, with new advancements, high efficiency heat pumps are available that provide better dehumidifying feature than the air conditioners.

The use of thermostat with a heat pump is always recommended as it adds to its efficiency. The thermostats used for furnaces and electric heaters are completely different than those used for heat pumps. This is so because, heat pumps not only provide heating but also can be used as air conditioners and dehumidifiers.

Since thermostats add efficiency to your heat pumps and also offer a lower energy usage, choosing the right thermostat for your heat pump is always important.

Here in this article, we will help you to choose the right thermostat for your heat pump.

Let’s first look at what are some of the criteria you should have in mind while selecting a thermostat.

How to choose the right thermostat for your HEAT PUMP?

As already mentioned heat pump thermostats are a bit different from the baseboard and furnace thermostats. The difference lies in their operation. While the baseboard/furnace thermostat have to control the temperature of a heating device, the heat pump thermostats switch from heating mode to cooling mode according to the seasonal variations. This should be kept in mind while choosing a thermostat for your heat pump. Typically, all thermostats come with clear labels as to what devices they are compatible with. Look for thermostats compatible with a heat pump.

Also, there are heat pumps with auxiliary or emergency heat, like a multi level furnace. Check your heat pump if it has that feature or not. Choose thermostat accordingly, that is select a thermostat that is compatible with your kind of heat pump.

Next is choosing the models for thermostat. This completely depends on your range of budget. You have programmable and non programmable thermostats as well as manual and digital thermostats available in the market. The programmable ones are more efficient and provide cool features like auto turn off/on, wi-fi support etc. while the manual thermostats are old school ones, simple, easy to use, pocket friendly yet not as efficient as their digital counterparts.

Let’s have a look at some of the heat pump thermostats available in market.
