How Heater Size Can Improve Energy Efficiency
On chilly winter nights, running your home’s furnace is essential for comfort and well-being. However, your furnace won’t last forever. In fact, the typical furnace will last only 15 to 20 years if it is regularly maintained in great condition. When the time comes to replace your furnace, factors like cost and energy efficiency will drive your model selection. However, it’s equally important to consider the matter of heater sizing when making a replacement. Heater size directly impacts your home’s energy consumption.
Signs Your Heater Needs to Be Replaced
From time to time, your heater may develop repair issues that can easily be resolved by your HVAC technician. However, when repairs are needed frequently on an aging system, a replacement should be considered. If your heater is approaching 15 years old or older, pay attention to warning signs like uneven home heating and higher energy bills. Short cycling, poor indoor air quality, burning or musty smells, rusting, cracks, banging, and squealing are also concerning. Your HVAC technician can inspect your heater and provide you with a fact-based recommendation for a repair versus a replacement.
Why Heater Size Matters
The size of your home’s heater impacts how well it can maintain the indoor climate at an ideal temperature. This directly impacts your comfort in each room in your home. Heater size plays a role in energy efficiency as well. For example, if your heater is too small for your home’s square footage, the heater will run for longer periods of time than it otherwise would. In addition to draining energy, this places additional wear and tear on the equipment. More frequent repairs and the need to replace the system prematurely are concerns.
On the other hand, if your heater is too large for your space, it will consume more energy than a more suitably sized unit would. In addition to increasing energy bills, a larger-than-necessary heater will also short-cycle. Because it turns on and off more frequently, you’ll deal with unnecessary wear and tear and uneven home heating. In addition, larger units have higher upfront costs.
How to Determine Heater Size
When comparing different models of heaters, you will notice a BTU rating. BTU means British Thermal Unit, and it indicates the amount of heat produced by the equipment in 60 minutes. Generally, units with a higher BTU rating are more expensive. However, other factors influence cost as well, such as energy efficiency and brand. A smaller heater uses less energy, but how long and how often the heater runs also affects energy consumption.
A home under 1,000 square feet generally needs a heater size between 24,000 and 40,000 BTUs. The recommendation increases by 20,000 BTUs for every additional 500 square feet in home size.
How to Choose the Right Heater Size for Your Home
Installing the right heater size for your home is essential, but what size is right for your specific home? Both the home’s square footage and layout are important considerations. The quality and amount of insulation also need to be taken into account. Inadequate insulation results in greater heat loss and increases demand on the heater. Another factor to consider is the condition of your air ducts. Heating demand is higher if air leaks through the ducts. Air leaks can also be found at the doors and windows.
On the other hand, if your home has many large windows facing south, it may benefit from natural solar heating. This could reduce the demand for heat in your home. With many factors at play, it’s important to consult with an HVAC specialist about your home’s specific needs.
