At Callahan’s Gas, we want to be your everything-under-one-roof partner for propane service. That means not only reliable propane delivery but also support for your propane tank and appliance needs, including the gas piping that connects your tank to the propane products and systems throughout your home.
Professionally installed gas lines are crucial for the safety, dependability and efficiency of your propane equipment. Gas piping is built to last, too. You can expect these lines to last for multiple decades — perhaps as long as 50 years — before needing to be replaced.
That said, there are circumstances when a gas line can become compromised and require a professional inspection, repair or replacement. Reasons that a gas line could become compromised include the following:
Our seasoned technicians are always available to inspect your propane gas piping, tank, regulators and appliances if you suspect there is a maintenance and/or safety concern. In this post, we’ll help you assess if a gas line problem exists on your property.
Your senses can give you a pretty good idea of whether there’s a problem with your propane gas line. Here are some warning signs that there’s definitely a problem:
If you notice any of these tell-tale signs of a compromised gas line, you need to respond appropriately.
If you notice structural damage on gas piping but do not smell gas, hear hissing or receive an alert from a gas leak detector, you should reach out to your propane company for a safety inspection. Licensed propane technicians like the Callahan’s Gas team can confirm that there is no leak, then look at your propane tank, piping, regulator and appliances and make any necessary repairs.
If you smell gas, hear hissing around your line or otherwise recognize a gas leak, you need to evacuate the home immediately. Extinguish any ignition sources like cigarettes or candles. Don’t use phones, light switches or other electronic devices in the affected area. Once everyone is away from the leak area, follow these steps:
Your safety and comfort are our top priorities. As a Callahan’s Gas customer, you can feel confident that we are here if there is a maintenance issue with your propane tank, regulator, gas lines or propane appliances. Our team has an encyclopedic knowledge of local and state codes. We are experienced in installing and servicing both rigid and flexible piping. Plus, we account for all BTU demand considerations. Rest assured, we’ll thoroughly address the problem and ensure your propane system is safe and reliable.

At Callahan’s Gas, we often hear this concern from our loyal customers after they receive a propane delivery: Why doesn’t my propane tank gauge read 100%?
It’s true that a full aboveground propane tank will typically read approximately 80% on its gauge. But that doesn’t mean you’re getting shortchanged on your propane delivery. In this article, we’ll explain how your tank gauge measures the amount of fuel you have and why propane companies follow an “80/20 Fill Rule.”
Your tank uses what’s called a float gauge. As that name suggests, there is a float that rests on top of your liquid propane. A stem connects the float to gears that cause the gauge on the outside of your tank to provide a reading.
Your tank gauge provides information about the percentage fill of the tank based on the volume of the liquid propane it contains. It doesn’t tell you the number of gallons inside.
And speaking of volume, propane tanks are viewed and sized through two different lenses simultaneously. The gauge measures the liquid level of propane. The total water capacity (WC) of the tank is how much water (or liquid) it would take to fill the tank to the brim. However, as mentioned above, a full tank of propane will sit at approximately 80% of that mark.
So, if the gauge on your 500-gallon (WC) propane tank reads 50, it is at 50% of its total water capacity and contains roughly 250 gallons of propane.
Liquid propane’s volume (the amount of space it takes up) expands as outdoor temperatures rise and contracts when temperatures drop. Water’s volume expands and contracts with temperature changes, too. However, propane expands nearly 17 times more than water with the same temperature change.
This can affect your tank gauge reading. If you have 250 gallons of propane in a 500-gallon tank, the gauge will read 50 on a moderate afternoon. If temperatures drop considerably at night, the gauge reading may be several percentage points lower, even though the number of gallons hasn’t changed.
This brings us to why your tank isn’t 100% full after a propane delivery. All responsible propane companies leave 20% empty space in aboveground propane tanks to allow for the safe expansion of propane. Doing so prevents unsafe pressure levels on hot days. As such, a full 500-gallon (WC) aboveground propane tank will contain approximately 400 gallons of fuel. (Underground tanks can be filled higher since they are less exposed to direct sunlight.)
Still, you don’t need to worry about being charged for that 20% of empty space. We only bill you for the propane gallons that we add to your tank at each delivery.

One benefit of propane that our customers love is being able to power many high-quality home comfort products from dedicated on-site propane tanks. Unlike natural gas or electric appliances, propane products aren’t dependent on a utility with often-unreliable infrastructure. In Queen Anne’s, Kent, Caroline and Talbot counties, Callahan’s Gas customers can count on a well-maintained propane tank that our team keeps filled to power their many products, including:
One question we hear a lot from our valued customers is how long they can expect their propane supply to last before needing a refill. In this article, we’ll discuss the calculations that go into planning your propane delivery schedule, which Callahan’s Gas can do for you at no additional cost.
The speed at which you’ll burn through the propane in your tank depends on a variety of factors, including how many gas appliances you have, how often you use them and the weather.
Every home is unique, and the calculation of various products’ consumption rates can become complex. One gallon of propane will generate 91,452 Btu of heat energy, but how many Btu you need varies by product. For example, running a propane fireplace product for three hours will use approximately one gallon of propane, whereas running a pool heater for that same period might use over 12 gallons of propane.
The Propane Education & Research Council has calculated some general annual consumption rates for propane appliances:
As you might imagine, accounting for all the variables that determine when you’ll need a propane delivery can get complicated quickly. Even if you’ve figured out the average consumption rate of your various systems or appliances, a sudden cold snap might throw your calculations off. The result could be an unexpected and unwelcome propane run-out that puts your home heating, hot water, cooking appliances and dryer out of commission.
Wouldn’t it be nice to have a professional team at your disposal to plan your delivery schedule for you? With Callahan’s Gas, you have just that!

We check this meter every month just like a utility company would and bill you only for the propane you’ve used.

This “pay-as-you-use” system provides you with a similar supply and billing experience to what you’d get with a gas utility.

When you choose us as your home comfort partner, you can be confident that your propane equipment, storage tank and fuel piping are 100% safe and functioning as they should. It is always the right call to bring in a professional propane installation team like ours to handle your gas line installation. Attempting a “do-it-yourself” installation is an extremely bad idea.
When non-professionals try to install propane gas lines, they can create severe safety issues on their property. A propane leak can pose a risk of explosion and/or asphyxiation. Installing your own propane piping can also seriously harm the safety, efficiency, longevity and general performance of your gas appliances.
We can virtually guarantee that a DIY gas line installation won’t save you money. People who try running their own lines almost always need to bring in a professional technician to repair their work, address safety concerns or do a full re-install.
When you bring in a professional propane team like Callahan’s Gas, you can rest easy, knowing you’re getting the best, most safety-focused installation service. Here are some examples of the considerable value you enjoy from a professional gas line installation:

Have you recently bought a home in Talbot County in which you own the propane tank on the property?
What’s the condition of that propane tank? Propane tanks have a resilient reputation, but they don’t last forever. If the propane tank that sits on your property shows signs of wear, then Callahan’s Gas has you covered. Instead of worrying about a failing tank that you are responsible for, let us help you with a worry-free replacement tank. We offer our customers cost-effective tank leasing options that ensure they always have top-quality, well-maintained propane storage at their Eastern Shore home.
When you lease a propane tank from us, our team will handle all the planning, installation and testing for you. We carry a selection of tank sizes and will help you find the ideal one for your household needs. Not only that, but we’ll also take care of all your tank maintenance and repairs. You’ll never have to worry about your tank again!
This can be a considerable financial benefit for the homeowners we serve. Owning a tank means that you’re on the hook for the purchase, installation, inspections, upkeep and any repairs that come your way. Leasing eliminates all that stress, uncertainty and cost. It’s little wonder that the majority of our customers choose to lease a tank from us.
The typical aboveground residential propane tank, which can range in size from about 100-500 gallons, can last well over 30 years. Underground tanks have slightly shorter lifespans.
One of the clearest indicators of a propane tank that’s past its prime is rust or corrosion on its surface. Some rust on an outdoor tank is normal, but a lot of it could mean the tank’s structural integrity is weak, making it more susceptible to leaks or ruptures.
An old, poorly maintained tank can cause your propane equipment to lose efficiency. It can prove to be a safety hazard, too. Happily, the Callahan’s team is always available to look at your aging home propane tank and arrange a top-of-the-line replacement.
Our employees follow the most rigorous propane safety standards. We provide ongoing safety inspections and testing for our fuel customers. If you are concerned about the state of your propane tank, reach out to us. We can perform a thorough safety inspection and provide recommendations.
Callahan’s Gas is also dedicated to providing customized, customer-focused service to homes that need propane service. We can take you through your options for a new propane tank installation and the advantages you can experience from leasing one of our tanks.
At Callahan’s Gas, we pride ourselves on the high quality and longevity of our tanks. By choosing us as your propane partner, you can rest easy knowing that we will keep your propane tank in peak condition, serving you for decades to come.

At Callahan’s Gas, we appreciate that homeowners have many choices when it comes to powering their heating equipment and other major appliances. Every day, we talk to people in Queen Anne’s County and throughout the Eastern Shore of Maryland about whether propane is the smartest choice for their household.
While every family and house is different, we’ve found that propane outpaces most energy alternatives on a range of criteria. Here are five benefits of choosing propane for your home.
With propane, you get a lot of heat energy for your money — 91,452 Btu of heat energy per gallon, in fact. That’s twice the heat generation per cubic foot of natural gas. It would take 27 kilowatt hours of electricity to achieve that level of heat production. This robust heat generation allows propane furnaces to reliably deliver heated air of up to 115° F when it’s icy cold outside.
Today’s propane furnaces and boilers have fuel efficiency ratings as high as 98.5%. So, you can be confident that almost all the propane you use is going to its intended purpose. Propane water heaters can have hot water recovery rates that are roughly twice as fast as electric units, and tankless propane water heaters are even more efficient. You can also enjoy considerably faster laundry drying with propane-powered dryers.
Propane has been listed as an alternative fuel in both the National Energy Policy Act and the Clean Air Act. Its carbon intensity (how much carbon dioxide is produced to generate a certain amount of energy) is lower than that of fuel oil, gasoline, and Maryland’s grid electricity. Propane is also methane-free and emits virtually no particulate matter.
When you have a propane tank at your home, you can power so much more than your home’s heating and hot water equipment. Propane also fuels a wide variety of indoor and outdoor appliances, including:
Additionally, you can enjoy energy security when there’s a grid outage by installing a propane-powered standby generator. Even when the grid fails, you can keep your lights, electronics, refrigerator and home medical equipment running.
Almost all the propane used in our country is produced in the U.S. In fact, we are a net exporter of propane. This means that there is a dependable domestic supply of the fuel we deliver. Also, propane is somewhat insulated from global energy markets compared to fuels that are more reliant on foreign sources. This makes its price much more stable.
If you’re looking for the most dependable, professional propane delivery service in the Mid-Shore region, look no further than Callahan’s Gas. Customers love our zero-stress Automatic Delivery option. With this free service, our cutting-edge computerized system uses your customer history and the weather to determine when you’ll need more propane. Then, we arrange your next delivery before you run low.
If you want to take advantage of Callahan’s top-notch propane services, join our happy family of customers today.

Do you have an electric water heater in your home? If so, the chances are your energy costs are unnecessarily high. Electric water heaters are known for their sluggishness and lack of energy efficiency. Given that water heating contributes to approximately 20% of your home’s energy expenses, you can feel the impact of this inefficiency in your wallet.
Upgrade to a propane water heater for enhanced energy efficiency, cost savings, and increased comfort. Whether you choose a conventional tank storage water heater or a high-efficiency tankless water heater, both options far surpass the performance of electric water heaters.
Callahan’s Gas offers expert installation, maintenance, and repair of quality propane water heaters from leading manufacturers. Regardless of your choice, you’ll experience significant energy savings starting from the day your new propane water heater is installed.
Propane storage tank water heaters offer efficient and cost-effective water heating. They heat water faster and at a lower cost compared to electric models, ensuring both comfort and savings. In fact, propane tank water heaters typically have operating expenses that are 40% to 60% lower than electric water heaters when considering energy costs, maintenance and repair expenses, and lifespan.
A tankless water heater offers significant energy savings while providing enhanced comfort and convenience.
By choosing a propane tankless water heater, you can reduce your water heating energy expenses by up to 40% compared to using an electric water heater.
A conventional water heater with a tank continuously heats and reheats water around the clock, ensuring a constant supply of hot water. However, this process consumes a significant amount of energy. On the other hand, a tankless water heater only heats water as needed, providing an endless supply of hot water while significantly reducing energy consumption. By opting for a tankless water heater, you can enjoy hot water whenever you need it while slashing your energy usage!
Cold water flows into the tankless water heater through a pipe, where it is promptly heated by a propane gas burner. The resulting hot water is then delivered directly to its intended destination: be it the shower, kitchen sink, or washing machine. This ensures that hot water is readily available wherever and whenever it is needed.
With a tankless water heater, you can bid farewell to worries if you require hot water in multiple locations! It continuously provides hot water for all your needs, no matter how long you need it. Picture this: you can enjoy a refreshing shower while the dishwasher is running, simultaneously do a load of hot-water laundry, or even accommodate someone taking a shower in another bathroom. Say hello to convenience and endless hot water!
A tankless water heater not only alleviates the concerns associated with a traditional water heater tank, but also eliminates the need for tank maintenance and the risk of breakdowns. In fact, tankless water heaters boast a lifespan that is approximately twice as long as that of their tank counterparts, offering exceptional returns on your investment. Enjoy peace of mind and long-lasting efficiency with a tankless water heater.
