The EM heat on the Honeywell thermostat is turned on when the temperature reaches a set point.

The EM system is a popular feature that is built into Honeywell thermostats. It helps to keep your home warm during the winter months by providing heat.

The auxiliary or backup heating source can be used in an event where the primary heating source is no longer functional. The backup electrical heating strip will maintain the temperature within the building.

We want to help you understand how to use the EM heat on your Honeywell thermostat system so that you can get the most out of your home’s heating.

Honeywell heating pumps

  1. The original three-pump heating system. This is the most common type of heating system and is used when the home has one or more central heating systems. It uses three pumps to heat the room, depending on the type of central heating system used.
  2. A two-pump heating system. This type of heating system is used when there are only two central heating systems in the home and one pump is used to heat both rooms in the home.
  3. A single-pump heating system. This type of heating system is only used when there are only one or two central heating systems in the home and one pump is used to heat just one room in the home

Primary heating pump

The Honeywell heating system has a standard heating setting that uses hot air from the environment to warm the inside and the outside at the same time. ..

Auxiliary heating pump

When the primary heat pump is not providing enough heat to maintain the indoor temperature, the heating system activates the auxiliary heating pump. The auxiliary heating pump uses an electrical heating strip as its heat source.

Tertiary furnace pump

In an event that disables the electrical heating strip, the auxiliary heating pump will switch to a gas furnace as its default heat source. A user may manually divert from an electrical to a gas heat source for budgeting purposes.

When to switch to Emergency heating: 

There are few precedents that would require enabling the emergency heating setting on your Honeywell thermostat. Some of which are: -If your home is in a cold weather emergency situation -If you have a child or pet who is sick and needs to be warm -If there is an impending power outage ..

In extreme weather conditions, the heat output of the primary heat pump might not be enough to raise the internal temperature of the room or building. It is advised to switch to emergency heating if necessary. The additional boost from the backup heating source would help maintain the required indoor temperature. ..

Emergency heating is a type of heating that is used when there is an emergency. This type of heating can help to keep you warm during the cold winter months.

Emergency heating systems are designed to provide heat in an emergency situation. They work the same as your primary heating system, but they have a special switch that turns on when there is an emergency.

The secondary heating pump is now being used to supplement the necessary heat to maintain the internal temperature of a room or building. The emergency heating system uses a secondary heating source, which is either an electrical heating strip or a gas furnace. ..

Beware of when and how long to use the EM heating!

  1. The need for heat in the event of an emergency.
  2. The need to keep people safe from the cold and the elements.
  3. The need to provide warmth and comfort during winter months.
  4. The need for a reliable and affordable heating system that can be used year-round.

Skyrocketing Utility bills: 

The emergency heating system is not as energy-efficient as primary sources. So, if left for a prolonged time, the utility bills would be considerably higher when compared to using primary heating sources. In addition, secondary heating systems are designed to provide a greater output of heat, so they use up more resources than primary systems. Just something to keep in mind when switching to the emergency heating setting. ..

Do not use Manual switching if possible: 

If you’re not sure whether or not the automatic Honeywell emergency heating system is working, it’s recommended that you don’t switch to the emergency heating system manually. This requires resetting the primary heating system, which can be risky if you’re not careful. ..

Conclusion

So, in conclusion, the Honeywell thermostat em is a device that helps you keep your home comfortable all year round. It uses an algorithm to determine when it is necessary to turn up the heat and when it is safe to let the room cool down.

Just be careful not to overuse the setting. Because, the em is meant for emergency situations. Prolonged use could wear out the internal mechanisms of the units and lead to further headaches down the road. Also, keep an eye on the thermostat. We do not want you good folk to pay more than necessary."

The following are some commonly asked questions

If you see an indicator light next to the emergency heating button, then the em heating is on. ..

Emergency heating is a type of heating that is used in cases where there is an emergency. This type of heating uses gas or electrical strips to supply heat, which can be a burden to upkeep.

No, Honeywell emergency heating is an automatic process. The units have built-in sensors that allow the system to know when to divert the heating systems. Manual switching is enabled but is generally discouraged due to previously stated reasons. ..

The two main types of heating are primary and emergency. Primary heating uses the environmental heat to warm the indoors, while emergency heating uses electrical heating strips or gas furnaces (which have a greater output but are more expensive). ..
