Snow & Heating Costs Can Pile Up With the 2019 winter heating season just around the corner for most of the United States, the title of this article is the most popular query I have been asked over the years about Heating Systems. Unfortunately the answer is not that simple and the answer depends on several variables.
If you ask someone who is associated with Oil heating in any way, shape, or form, the answer is Oil.
If you ask someone who is associated with Gas heating in any way, shape, or form, the answer is Gas.
Both "someones" are leaving out important details and information so immediate justification for their fuel can be given.
The question now becomes:
Who is correct? Here is the TRUE answer:
Depending upon several different circumstances either answer can be correct...
The reason for this is because heating your home ALSO depends on what type of Heating Unit being used and HOW Heat is Delivered throughout your house. All Heating Systems consist of three (3) parts:
The type of Fuel used, the Heating Unit, and the Heat Delivery Method throughout the house.
The question now needed to be asked is:
What are the circumstances and how do we know what is the most efficient Fuel for us?
With OIL, the fact is more BTUs are produced by Oil as compared to Natural Gas, thus making Oil the more efficient FUEL at face value. HOWEVER, some Gas Heating Units offer the highest efficiency rates. Thus by using Gas as a Fuel in tandem with a higher efficiency Gas Heating Unit and a more efficient method of delivering the heat throughout the house, GAS becomes the more efficient FUEL.
BTU stands for British Thermal Unit. This is an approximation for the amount of energy needed to heat up one pound
of water, one (1) additional degree in the Fahrenheit scale.
Let us start to break down the circumstances...
First thing to realize is that there are numerous steps to improving and making all the components contributing to heating the house far more efficient. Even if you finally do decide to get a new heating unit, gas or oil fired, all the additional steps must be looked at, considered, evaluated and implemented when necessary for maximum energy savings. Below are two questions from some of my clients:
I now use oil to heat my house, the heating unit is almost seven years old and I have gas in the house. Currently natural gas is cheaper than oil. Do I make the switch from oil to gas?
Whenever the above details are true, the answer is No. This is because the cost to switch (at least $5,000 to $7,000) probably will have a long payback period of 7 years or more. Additionally, over the years the cost for oil and gas will follow historical trends making one fuel more expensive than the other from one year to the next. Another expense will probably come into play if the way heat is "delivered" throughout the house needs to be upgraded to one of the more efficient methods. Now this action with save more on heating costs, but add additional years to the payback period. Thus upgrading the way heat is delivered throughout the house, such as changing from a Hot Water Baseboard delivery method to a Hot Water Radiant Floor Heating method, will wipe out the additional savings gained.
Rating the way heat is delivered throughout the house:
If you ask someone who is associated with Oil heating in any way, shape, or form, the answer is Oil.
If you ask someone who is associated with Gas heating in any way, shape, or form, the answer is Gas.

Rating the way heat is delivered throughout the house:
Radiant Floor Heat Most efficient delivery method to send heat around your house:
Hot Water Radiant Floor Heat
(Today, PEX tubing - not copper pipes, would go down first in order to be under the floor. This is best installed with new construction or complete remodeling projects.)
Hot Water Baseboard Second best delivery method to send heat around your house:
Hot Water Baseboard
Then comes methods such as:
Forced Hot Air; Hot Water Radiators; Steam Radiators / Steam Pipes; etc.
(The order of efficiency for these methods could alternate depending on other variables in the house, such as how well the house is insulated and / or the location of vents. {Facts on vent location is below})
Also please note these delivery methods of heat throughout the house become less efficient with additional variables.
For example: Forced Hot Air coming out of one set of vents on the wall where the vents are up by the ceilings. This (less expensive to install for a builder) "single room vent" with a dual function for delivering heat in the winter and AC cold air in the summer, has a much higher expense in energy cost for the homeowner due to a lower efficiency with delivering heat. The reason for this is because we have basic laws of physics that state Hot Air Rises. Why then would we place the vent that delivers heat to a room up by the ceiling and not down near the floor? Vents by the ceiling are only good for delivering Cold Air from a central AC system, because Cold Air Drops. Another law of physics. We all need two vents per room, one for heat by the floor and one for cold air at the ceiling.
Below is another question from a different client:
I have oil heat for my house and the boiler (heating unit) needs to be replaced. I have gas in the house for my gas stove and clothes dryer. Should I switch from oil to gas and will I save money on my heating bills?
The answer will be Yes, if all the answers to the following questions are YES...
- Do you have Hot Water Baseboard or Hot Water Radiant as the Heat Delivery method throughout the house?
- Can you get the new gas heating unit installed with a rebate, tax credit, or low interest loan?
- Is the new gas heating unit offering a high efficiency rating of at least 87%?
If your answers are NOT all YES, then consideration should also be given to a new more efficient oil heating unit, compare the numbers with payback times as well as look at all other elements connected to lowering overall operating costs for heating. For example: Insulation levels throughout the house and if hot water pipes are covered with insulated wrap.
WARNING - Please Note that sometimes we can get an incentive from our utility company for converting, when they also provide Natural Gas service, but in most cases they are only offering a new gas heating unit that provides 80% efficiency or less. A far cry from 87% and the better gas heating units that offer up to 95% efficiency.
