🛎️ Result of Round 3: Boiler/Hydronic Systems
Maintenance is paramount for both of these heavy weights to stay in tip-top shape. However, because boilers don’t require routine filter replacements, we’re giving the slight edge to Boilers/Hydronic Systems.
Round 4: Maintenance Costs
In round four, we examine the financial aspect of keeping each system running smoothly.
Forced-Air Furnaces have lower maintenance costs due to the simplicity of tasks like filter replacements and the widespread availability of service technicians with the skill set to service forced air systems.
Boilers/Hydronic Systems may incur higher maintenance costs when maintenance is needed. A specialized skill set is often required to perform proper maintenance on these systems that fewer technicians possess.
🛎️ Winner of Round 4: Forced-Air Furnaces
With lower ongoing maintenance expenses, forced-air furnaces take this round.
Round 5: Repair Costs
In round 5, we’ll consider the cost of unexpected setbacks and repairs.
Forced-Air Furnaces typically have lower repair costs. Parts are readily available, and many HVAC technicians are well-versed in furnace repairs, keeping labor costs competitive.
Boilers/Hydronic Systems can be more expensive to repair. Specialized components and fewer technicians trained in boiler repair can lead to higher costs.
🛎️ Winner of Round 5: Forced-Air Furnaces
Forced-air furnaces score again with more affordable repair costs.
Round 6: Indoor Air Quality
In round six, we focus on how each heating system fairs in the realm of Indoor Air Quality.
Forced-Air Furnaces circulate air through ducts, which can distribute allergens and dust if filters are not changed regularly and ducts aren’t cleaned. However, this is where the adaptability of a forced air system comes into play. Many add-ons can take a forced air systems indoor air quality control to new heights. These add-ons include UV-germicidal lights, higher MERV rated filters, and whole-home humidifiers.
Boilers/Hydronic Systems heat without circulating air, meaning they don’t spread dust, pollen, or other allergens. This can be a significant benefit for individuals with allergies or respiratory issues.
🛎️ Winner of Round 6: Forced-Air-Furnaces
Without additional upgrades, boiler systems would have taken this round. However, considering add-ons available to forced air systems, we’re giving a slight edge to the forced air system.
Round 7: Humidity Control
As the match progresses, we examine how each system affects indoor humidity.
Forced-Air Furnaces can dry out indoor air, leading to discomforts like dry skin and static electricity. Humidifiers can be added to mitigate this, but it’s an extra expense and maintenance task.
Boilers/Hydronic Systems maintain indoor humidity levels more effectively since they don’t remove moisture from the air. This helps prevent the dry air conditions often associated with winter heating.
🛎️ Winner of Round 7: Boilers/Hydronic Heating Systems
With better humidity retention, boilers win this round.
Round 8: Noise Levels
Entering round eight, we listen to how much noise each system makes during operation.
Forced-Air Furnaces While many variable-capacity and multi-stage furnaces can be incredibly quiet, they aren’t quite on par with boiler systems. Forced air furnaces tend to be noisier due to the blower fan and air moving through the ducts, leading to audible cycling on and off.
Boilers/Hydronic Systems operate almost silently. The absence of blowers and moving air means minimal noise, contributing to a peaceful home environment.
🛎️ Winner of Round 8: Boilers/Hydronic Heating Systems
Boilers score with their quiet operation, enhancing home comfort.
Round 9: Energy Costs
In this crucial round, we evaluate which system is more cost-effective to operate.
