Feeling at Home with Propane
It can take months to feel comfortable in a new home. We're here to help the system behind the comfort — your propane heating system — feel familiar, safe, and reliable.
Family owned and operated since 1993
Dear Neighbor,
Welcome to your new home.
If this is your first experience heating with propane, you may be wondering how much you need to know. How often will the tank need to be filled? What does the gauge mean? Who do you call if something seems off?
Those are all normal questions.
At Dileo Gas, we work with homeowners every day who are settling into propane-heated homes, sometimes for the first time. We know the system can feel unfamiliar at first. But once someone takes a little time to explain it, propane becomes much easier to understand.
Dileo Gas has been family-owned and operated since 1993. Our company was built around a simple promise: never leave families in the cold.
That promise means showing up reliably and taking safety seriously. It means being available in an emergency—always. And it means helping homeowners understand their options before anything becomes urgent.
To that end, we've created this online resource to help you get more comfortable with your propane system. Nothing overly technical or complicated. Just useful things homeowners often wish they'd known sooner.
For now, the main thing is this:
You don't need to know everything today. You only need to know that you have people you can call when you have a question.
"Warmth should be one less thing to wonder about."
Congratulations on your new home—and welcome!
Warmly,

Homeowner's Knowledge Base
Useful things homeowners often wish they had known sooner. Click a topic to learn more.
Reading the Tank Gauge
One of the simplest things you can learn is where the tank gauge is. It usually reads as a percentage, not gallons.
Automatic vs. On-Demand
Automatic: We monitor usage and schedule deliveries for you.
On-Demand: You keep an eye on the gauge and call before the tank reaches 20%.
Safety Basics
Know what propane smells like before you ever need to. Many describe the smell as similar to rotten eggs.
Cold-Weather Confidence
When temperatures drop, you'll see the tank level moving faster. This is normal. Cold weather simply asks more of the system.
Propane Beyond Heat
Propane often does more than heat. It may support hot water, cooking, fireplaces, generators, or even pool heaters.
Storm Readiness
Storm readiness is not only about fuel. It is about access, safety, clear information, and knowing who to call.
Understanding Your Home's Propane Rhythm
After you have lived with a new home for a little while, you usually begin to understand it differently. You learn which rooms stay comfortable, and which ones take a little longer.
DiLeo Gas was built as a family business, and the promise behind it has always been simple: never leave families in the cold. To us, that means more than delivering propane. It means answering the phone and helping people understand their options.

Your tank is well-supplied. You have plenty of propane for normal household use. This is an ideal level — tanks are typically filled to 80% to leave room for propane to expand safely as temperatures change.
Tank Placement & Setback Requirements
Where can your propane tank safely sit? Explore clearance requirements for 50 gallon, 120 gallon, and 2x120 gallon vertical residential tanks.
