Introduction to electric furnaces
Electric furnaces are a great choice for warming up homes. Low-cost and efficient, they use heating elements to heat the air. No combustion byproducts, like carbon monoxide, makes them a safer option! Heat pumps can also substitute electric heaters to cut energy costs.
ERH technology is a unique feature of electric furnaces. It works by applying current through electrodes in contaminated soil or groundwater. Boiling point temperatures rise, converting it into vapor which is extracted with steam strips from surface wells.
In Ann Arbor, Michigan, ERH removed over 90% of dioxane-contaminated groundwater in six months!
Electric furnaces – affordable, safe and efficient. Plus, demand controllers can help with energy efficiency, reducing electricity usage during peak times.
Heating elements in electric furnaces
Electric furnaces don’t all use the same heating element. The size and heat demand can affect what type is used. Some may be more energy-efficient or have longer warranties.
Vapor phase heating was initially developed for subsurface remediation with ERH. ERH is a thermal technology that uses electricity to heat and vaporize contaminants like oil and carbon. This can help companies save money on contaminated groundwater sites.
Taming the heat in electric furnaces is like taming a wild dragon. A demand controller and resistance heaters are the weapons of choice.
Control systems for heating elements
Controlling electric furnace heating elements is key for efficient temps. There’re various control systems, each has its own attributes and costs. To give more info, I made a table of the different systems and their features.
| Control System | Attribute |
| Demand Controller | Reduces energy during low demand and stops carbon monoxide. |
| Resistance Heating Elements | Cheap to replace, avg cost $20 per year. |
| Electric Heat Pump | More efficient than other electric furnaces but needs larger heat exchanger. |
Electric furnaces have low heating efficiency compared to gas furnaces. This can be improved with radiant heating or steam stripping. Radiant heating uses electrodes to deliver heat into solid substances. Steam stripping uses vapor phase heating to take out contaminants from groundwater.
No PhD in ERH or steam stripping? No problem. I can still turn up the heat in an electric furnace!
ERH remediation and steam stripping
ERH (Electrical Resistance Heating) and steam stripping are two popular methods for remediating contaminants in the subsurface. ERH involves heating the soil or groundwater with electrodes. Steam stripping injects steam to evaporate contaminated water.
Each of these methods has its own advantages and disadvantages. ERH is better for low temperature heating demands, like homes. Steam stripping is great for larger volumes.
Before choosing a remediation option, consider all factors. Consult with professionals if needed.
Plus, why settle for just heating when you can get a two-for-one deal on comfort with an electric heat pump?
Electric heat pumps as an option
Electric heat pumps are great for homes that don’t need extreme temperatures. Unlike electric furnaces, they don’t heat by resistance. Instead, they move air between inside and outside, taking advantage of the temperature difference. This saves money on energy bills, as the cost of using a pump is 40% lower than an electric furnace. No need to worry about combustion’s contaminants either.
Two of the most recommended types are Ground-source and Air-source pumps. Sizing depends on factors like volume and demand control. Carbon monoxide detectors can help identify hazards.
Owning an electric heat pump also brings benefits like depreciation and an eco-friendly choice. Many options are now available at affordable prices – don’t miss out! Electric furnaces will keep you warm and save your wallet!
Gas furnaces versus electric furnaces
Gas furnaces and electric furnaces are both great heating systems for homes. Gas furnaces provide heat more effectively during cold months, whereas electric furnaces typically cost less to install and maintain. To help you compare the two systems better, I created a table with their differences.
Comparison Table: Gas Furnace vs Electric Furnace
| Features | Gas Furnace | Electric Furnace |
| Fuel Source | Natural gas or propane | Electricity |
| Installation and Maintenance Costs | Higher | Lower |
| Emissions | Produces Carbon monoxide | No combustion emissions |
| Flue or Venting System | Required | Not Required |
| Energy Efficiency Rating (ERH) | Higher than electric heaters | Lower compared to gas furnaces |
It’s important to examine the distinct features of these furnaces when deciding which one is best for your home. For instance, if natural gas isn’t available in your area, an electric furnace might be a better option. Similarly, if you’re sensitive to contaminants like carbon monoxide, then an electric furnace may be the way to go.
Fun fact: According to Energy.gov, replacing your old furnace with an energy-efficient model can save you up to 15% on heating costs each year!
Conclusion
Heating systems are essential for every abode. As homeowners, we want an energy-efficient system that warms our homes and is easy on the pocket. It should also be easy to maintain, long-lasting, and free from pollutants like carbon monoxide.
To determine which heating system suits your home needs best, it’s important to know the advantages and disadvantages of each. Here’s a comparison table to aid you in selecting the correct heating system for your home.
| System Type | Average Cost | Energy Consumption | Warranty | Contaminants |
| Electric Furnace | $1,500 – $3,000 | High (Uses electricity) | 10 – 20 years | None |
| Gas Furnace | $2,500 – $6,000 | Low (Uses natural gas) | 15 – 20 years | Carbon Monoxide |
An electric furnace utilizes several heating elements powered by electricity. Installing one is cheaper than a gas furnace since there’s no need for pipeline installation. But running it can mean increased electricity bills. On the other hand, gas furnaces are costlier and suited for large homes with more heat demand.
It’s important to bear in mind that both types of furnaces require regular servicing to keep them functioning well and their warranty valid. Consider size options when picking a furnace to ensure enough heat circulates through your house while not consuming too much energy.
Pro Tip: Take into account the type of fuel available at your home when deciding on an electric or gas furnace as it affects cost and convenience in the long run.
