Thinking About Upgrading Your Heating System? Here’s How You Pick The Most Efficient One

As temperatures cool off and winter approaches, the energy efficiency of your most efficient home heating system becomes an ever more important consideration. Upgrading can increase comfort and lead to significant energy savings over time. This is where experts from Daigle Plumbing, Heating & Cooling can help, offering tailored advice and solutions for your specific needs.

Thanks to technological advances, there’s now a wide variety of heating system upgrades promising greater performance and energy savings. This comprehensive guide will review key factors to remember when upgrading the heating system to ensure you find the most energy-efficient option for your home.

Assess Your Current System

Before beginning any heating system upgrade process, evaluating your existing, most efficient HVAC system is vital. Acknowledging its strengths and weaknesses will give valuable insights into which upgrade solution best meets your needs. When doing this, take note of:

Type of System

First, determine your heating type: furnace, boiler, heat pump, or radiant heating. Each of these options has its own set of advantages and disadvantages. Awareness of them will enable you to make informed decisions regarding upgrade plans that might benefit you.

Fuel Source

Discover your current system’s fuel source: natural gas, oil, electricity, or solar energy. As this information will shape upgrade options available to you and impact the performance of the most efficient HVAC system. 

Age and Efficiency

Note the age and efficiency rating of your current system. If yours is older and offers fewer energy savings potential, upgrading the heating system could yield significant cost-cutting measures.

Consider Energy Efficiency Ratings

Energy efficiency should always be an integral consideration when purchasing a heating system. Efficiency measures for these products typically use Annual Fuel Utilization Efficiency (AFUE) or Seasonal Energy Efficiency Ratio (SEER), with higher ratings indicative of greater energy efficiency.

An AFUE rating of 90% or above for gas furnaces and boilers is considered highly efficient; heat pumps and air conditioners should have SEER ratings of 14 or higher for optimal efficiency. Investment in more energy-efficient systems might come with higher upfront costs. However, choosing more effective systems will reap substantial long-term energy savings. 

Explore Different Types of Heating Systems

Heating systems come in all forms and shapes, each designed to suit specific preferences and needs. Here are a few popular choices available today:


Gas and oil furnaces are popular choices among many homeowners. Also, the most efficient home heating system distributes the hot air throughout your home using the ducts. Consider investing in a condensing furnace that captures excess heat to increase efficiency. 


Boilers are available as alternatives that heat your house through central boiler systems. These systems usually heat the water and distribute it through radiators or in-floor heating systems for even heating with quiet operation. They have become widely recognized for providing consistent, even temperatures while remaining quiet when operating.

Heat Pumps

Heat pumps often use electricity to transfer heat between indoor air and the outdoor environment or ground, providing heating and cooling functions – making them versatile solutions for any environment.

Radiant Heating

Radiant heating works by warming floors, walls, or ceilings, emitting warmth into your living space – offering an efficient yet comfortable way to heat your home.

Hybrid Systems

These hybrid and most energy-efficient HVAC systems combine different sources, such as heat pumps and gas furnaces, for maximum efficiency in all weather conditions.

Geothermal Heat Pumps

Geothermal Heat Pumps have become another great heating source option as these hybrid systems switch between sources according to efficiency and weather conditions. These pumps offer highly cost-efficient and environmentally friendly heating options. It utilizes the consistent temperature of the earth for better results.

Size Matters: Proper Sizing of Your Heating System

Selecting an efficient and cost-efficient heating system requires selecting an appropriately sized system. A system that’s too big will frequently switch on and off, leading to energy wastage and uneven heating; conversely, one that’s too small will struggle to maintain desired temperatures. When making this decision, consider factors like:

Square Footage: To accurately estimate heating capacity needs, measure the area covered by your home.

Insulation and Air Sealing: A well-insulated home that is properly air-sealed requires fewer heating systems as its insulation retains heat more effectively than an uninsulated and poorly sealed one.

Climate: Your regional climate is integral to determining how much heat load your heating system must handle. 

Window and Door Effect: Windows and doors play a large part in heat loss; make sure your calculations consider this factor when making calculations.

As it’s best to consult a qualified HVAC technician to perform a heat load calculation and identify an appropriate system size, it is wise to seek professional advice regarding heat load calculations for your home.

Fuel Options and Availability

Your choice of fuel for your most cost-efficient heating system can enormously affect efficiency and cost. Different options come with their costs and availability depending on where you live; here are a few common alternatives:

Natural Gas: Natural gas heating can be the more cost-effective and energy-efficient choice; however, availability may differ depending on where you reside.

Propane: This alternative fuel solution may offer efficient heating but incur higher fuel costs than natural gas.

Oil: Oil-based heating systems have become less common due to environmental considerations and fluctuating oil prices. 

Electric: Electric heating systems may be easier to install but may prove more costly in regions with higher electricity costs. Using these systems would be beneficial if you are looking for the most efficient way to heat a house with electricity. 

Renewable Energy: Solar panels, geothermal heat pumps, and biomass systems are sustainable ways of cutting your carbon emissions significantly.

Consider Smart Thermostats and Zoning

Optimize the efficiency of your new and most energy-efficient HVAC system by incorporating smart thermostats and zoning techniques. Smart thermostats give you remote access to control your heating, creating customized schedules based on your preferences, while some models even learn and adapt settings accordingly. Zoning divides your home into separate sections which can be heated independently. Also, the most efficient home heating can help increase comfort while optimizing energy usage.

Installation and Maintenance

Proper installation is crucial for optimizing the performance of cost-efficient heating systems. Poor installation can lead to reduced efficiency, increased energy bills, and even system malfunctions. Therefore, it’s advisable to hire licensed HVAC professionals in Derry who are experienced in installing your specific type of system.

Your HVAC system requires regular maintenance checks to function efficiently, including cleaning, lubricating, and inspecting components to ensure optimal performance & avoid costly breakdowns.
