How you choose to heat your home in St. Louis isn’t a decision to make lightly. A heating system is a sizable investment that will serve your home for many years to come. There are numerous variables to consider when selecting a new home heating system. Increasingly unpredictable winters paired with rising energy costs are increasing the need to consider which heating type will deliver comfort and reliability.
When selecting which heating system is better for your home, there isn’t a one-size-fits-all answer. Heat pumps and furnaces each have their own array of pros and cons. Scott-Lee Heating Company is your local heating expert in St. Louis, MO. We will discuss the primary differences between heat pumps and furnaces and how they directly affect St. Louis homes.
Key Considerations When Choosing a Heating System
As you look into a new heater for your home, you’ll want to think about comfort. Comfort doesn’t pertain only to how well the system warms your home. It also includes the cost impact of daily living. Think about how comfortable your wallet will be with an efficient heating system versus a not-so-efficient one. Consider a heater that uses primarily electricity to operate in comparison to one that uses gas.
When selecting between a new furnace and a heat pump, consider the climate here in St. Louis. Winters have a wide range of potential precipitation. Ice, snow and freezing temperatures are all aspects you will contend with during Missouri winters. You need to think about which heating system will keep your home the warmest during the coldest nights. The one that doesn’t struggle as hard to keep up with heating demand could result in long-term energy savings.
Heat Pump or Furnace: An Overview
Heat pumps and furnaces are both top choices for heating in St. Louis homes. They both produce heat but in different ways. It’s essential to understand the basics of how each system works before diving deeper into the differences.
Heat pumps do not generate heat; they only move existing heat around. They draw heat from the outside air to heat the inside of your home. Most of these systems run on electricity.
A furnace has the ability to produce heat by burning fuel. There are multiple types of furnaces to choose from. Some of the most common use natural gas, propane or electricity.
St. Louis Weather: Heat Pump vs. Furnace Performance
While the weather in St. Louis doesn’t get as cold as some areas of the United States, it does frequently drop below freezing. Heat pumps are great options for moderately cold climates. St. Louis falls into this category. The recent technological advancement in heat pump systems allows heat pumps to easily handle brief periods of subfreezing temperatures. On the other hand, if the temperatures remain drastically below freezing for an extended period of time, they could struggle to keep up with the household’s heating demand.
However, when the coldest winter air arrives, a furnace won’t let you down. A furnace can operate at extremely low temperatures without struggling. A furnace is able to provide consistent heat throughout your home. This holds true even if temperatures remain below freezing for multiple days during a cold snap.
Cost Savings and Energy Efficiency
When you’re selecting between a furnace and a heat pump, you need to think about energy efficiency. A high level of energy efficiency has a close relationship with cost savings. An energy-efficient unit uses less energy to operate, decreasing your heating bills.
Furnaces thrive in cold winter weather. Installing a new furnace, especially a high-efficiency one, will keep your home toasty even in the lowest of temperatures. When the temperatures plummet, a furnace can heat your home fast by producing heat on demand.
A heat pump will still warm your home, but it does so in a much more gradual way. A heat pump is overall more efficient than a furnace to operate. But it will take an extended amount of time for a heat pump to pull heat from the outdoor air. This is especially true during a period of prolonged cold weather. In fact, you might need to rely on a backup heat source if the temperatures stay too cold for too long.
Installation, Upkeep and Lifespan
There are some additional aspects of both heat pumps and furnaces to weigh before making a choice. For instance, consider up-front costs to install the systems. Each one requires slightly different upkeep. It’s also beneficial to take into account their typical lifespans.
Installation
For both types of systems, Scott-Lee Heating Company will determine the correctly sized equipment for your home. We will look at the layout, square footage and other factors to calculate this. Once you know the size, you can compare potential cost factors. A furnace installation costs substantially less than a heat pump. A furnace can easily fit into most homes, but it may require adding a gas line, depending on the type. Depending on the capacity of your electrical panel, installing a heat pump may require you to upgrade it. An electrical panel upgrade will support the electrical load that a heat pump will add to your electrical system.
Maintenance
When it comes to maintenance, both systems need annual heating tune-ups. A heat pump tune-up is more basic than one for a gas furnace, which includes checking the pilot light, ignition, possible gas leaks and making other system checks. A heat pump doesn’t have any of those things to check for.
Lifespan
The lifespan of each system is another big factor. Heat pumps have a slightly lower lifespan than a furnace. A heat pump will last an average of 12 to 15 years. A furnace will last an average of 15 to 20 years.
Choosing the Right Heating System for Your Home
Deciding between a heat pump and a furnace is a big decision. Scott-Lee Heating Company can tailor a quote for your specific needs. Even though we can quote the installation costs, you should weigh the long-term effects.
