Should I Turn My Heat Pump Off In Extreme Cold?

Posted on: March 13, 2023

When temperatures begin to drop, it’s natural to worry about the safety and efficiency of your home’s heating system.

In extremely cold weather, many homeowners wonder if they should turn off their heat pump to avoid damage or increased energy costs.

However, while it is important to take some precautions in extreme cold, turning off your heat pump is not necessary and may even be harmful.

This article will explain why leaving your heat pump on in extreme cold is better for your home, discuss what temperature is considered extreme cold, and provide other helpful information about heat pumps and emergency mode.

With this knowledge, you can make the most of your heat pump and stay comfortable in any weather.

What Temperature is Considered Extreme Cold for a Heat Pump?

When it comes to extremely cold weather, your heat pump’s ability to keep your home warm can be put to the test.

But what temperature is considered extreme cold for a heat pump?

Let’s take a closer look.

1. The Temperature Threshold

Extreme cold refers to temperatures lower than what your heat pump is designed to handle.

While the exact temperature threshold varies depending on the manufacturer, a good rule of thumb is temperatures lower than -13°F (-25°C).

2. Ground-Source Heat Pumps and Auxiliary Heating Sources

If you have a ground-source heat pump or a system with an auxiliary heating source, the extreme cold temperature may be slightly higher.

However, it’s important to check your heat pump’s specifications to be sure.

3. Supplemental Heat or Dual-Fuel Systems

Some heat pumps may need supplemental heat or a dual-fuel system in extreme cold weather conditions.

It’s essential to check your manufacturer’s guidelines and recommendations before using any supplemental heating sources.

How to Check Your Heat Pump’s Specifications

If you’re wondering how to check your heat pump’s specifications, there are a few things you can do.

Here are some tips:

1. Calculate the Size of Your Heat Pump

To determine the size of your heat pump, you can use a Manual J calculation or a square footage method.

The Manual J calculation takes into account factors such as the size and layout of your home, insulation levels, and more.

The square footage method is simpler and involves multiplying the square footage of your home by a certain number based on your climate zone.

2. Look for HSPF and SEER Ratings

The efficiency of your heat pump can be measured by its HSPF (heating) and SEER (cooling) ratings.

These ratings indicate how much energy your heat pump uses to produce heat or cool air. The higher the rating, the more efficient the heat pump.

Understanding Emergency Mode in Heat Pumps

If you’re a homeowner with a heat pump, you may have heard of “emergency mode” but are unsure of what it means.

Here’s what you need to know:

1. What is Emergency Mode?

Emergency mode is a setting on your heat pump that activates a backup heating source when your main heating system fails or when it’s too cold for your heat pump to work efficiently.

This backup heating source can be electric resistance coils or a gas furnace.

2. When Should You Use Emergency Mode?

The emergency mode should only be used as a last resort when the temperature outside drops below freezing and your heat pump is unable to keep up with demand.

Using emergency mode too often can cause your energy bills to skyrocket, so it’s important to use it sparingly.

3. How Can You Tell If Your Heat Pump Is In Emergency Mode?

You can tell if your heat pump is in emergency mode by looking for an “em heat” indicator on your thermostat.

If this indicator is lit up, it means that your heat pump has switched into emergency mode and is using its backup heating source.

What is Emergency Mode in Heat Pumps?

Heat pumps are an efficient way to heat and cool your home, but what happens when they fail? That’s where emergency mode comes in.

1. Definition of Emergency Mode

Emergency mode is a setting on your heat pump that activates a backup heating source when your main heating system fails or when it’s too cold for your heat pump to work efficiently. This secondary heating source can be electric resistance heaters, gas furnaces, or oil burners.

2. When to Use Emergency Mode

The emergency mode uses more electricity than the normal mode and should only be used as a last resort. It’s recommended to use the emergency mode only when other methods of heating aren’t available or if there’s a risk of frozen pipes due to extremely cold temperatures.

3. Identifying Emergency Mode

You can tell if your heat pump is in emergency mode by looking for an “em heat” indicator on your thermostat. This means that the backup heating source has been activated, and you’re no longer using the heat pump alone.

Does every heat pump have emergency mode?

When it comes to heat pumps, having an emergency mode can be a real lifesaver.

This feature, also known as an auxiliary mode, is designed to kick in when your primary heating system fails or cannot keep up with demand.

However, not all heat pumps come equipped with this feature.

The presence of an emergency mode varies depending on the type and model of your heat pump.

To determine whether your heat pump has this essential feature or not, you may need to refer to your unit’s manual or contact the manufacturer directly for more information.

Why You Should Not Turn Off Your Heat Pump in extreme cold?

Turning off your heat pump in extremely cold weather may seem like a good way to save energy and reduce costs, but it can actually cause more harm than good.

One of the biggest risks of turning off your heat pump is the increased likelihood of frozen pipes and other winter-related issues.

When your home’s temperature drops too low, the water inside your pipes can freeze, causing them to burst and potentially leading to costly repairs.

Another reason why you should not turn off your heat pump in extreme cold is that it can result in higher energy bills when you turn the unit back on to warm up your home.

This is because when you turn off the heat pump, the indoor temperature drops significantly, and once you turn it back on again, it will take longer for your home to reach a comfortable temperature.

As a result, your heating system will have to work harder and use more energy to bring the temperature back up again.

Lastly, turning off your heat pump can also result in longer wait times for your home to reach a comfortable temperature again. This means that you’ll have to wait longer until you feel warm enough and comfortable.

In extremely cold weather conditions, this can be particularly uncomfortable and even hazardous for some individuals such as children or elderly people who are more susceptible to hypothermia.

Therefore, it’s best not to turn off your heat pump during extreme cold weather conditions as doing so could lead to potential safety hazards and higher costs in terms of both time and money.

Final Verdict: Should I Turn It off or Switch to Emergency Mode in extreme cold?

As a general rule, you should not turn off your heat pump in extreme cold.

Your heat pump is designed to operate in both cold and warm weather, and turning it off could cause damage to the unit or lead to other issues like frozen pipes.

Instead, it’s best to leave your heat pump on and let it run as normal.

If your heat pump is not providing enough heat, you may need to switch to emergency mode as a temporary solution until you can have it repaired.

However, the emergency mode should only be used as a last resort because it uses more electricity and can be expensive.

If you’re not sure what to do, it’s best to contact a professional technician to assess your heat pump and provide guidance on the best course of action.
