Maintaining Pressure is Key
Fluid level and temperature maximize pressure in a propane tank. There are a few situations that can cause your propane tank to freeze, including:
- When the tank is low or not full and it’s cold outside, and the pressure drops
- Temperatures below -44°F, the boiling point of propane, means it cannot vaporize, making the product unusable.
- If your tank is drawing more pressure than it is designed for, or drawing too much pressure in a short period of time.
Safe Heating Methods
Keeping your propane tank full is one safe heating methods. There are a couple of other safe heating methods to maintain the tank pressure and keep it from freezing. Fuel use will be more efficient if the tank is operating properly.
Insulated Heating Blanket
If you simply plug in an insulated heating blanket, this allows you to safely and easily control temperature and pressure.
Gas Cylinder Heaters
Gas cylinder heaters provide a uniform barrier of heat across the entire cylinder.
Heating Practices Not Recommended
It is important to know of more conventional methods that have been used, but are quite dangerous and not recommended. Propane is much safer than some other fuel sources, but it is still flammable and should never be exposed to open flames or an uncontrolled heating source. Heating practices for your propane tank that we do not recommend include:
- Hot water
- Tank submerged in water with boiler underneath it
- Blow torches
- Space heater
Winter Tank Maintenance Tips
With an operational tank, there are a few other tips for good winter maintenance that will keep your family and your business safe and warm through the cold winter months.
- Mark the location of your propane tank with a flag or stake that will be visible in the case of snow.
- Clear any snow or ice from off or around the tank with something soft, such as a broom. Anything made of hard metal or plastic, such as a shovel, should not be used for this.
- Do not use a snow blower near the meter.
- Keep valves, piping and the meter clear of snow and ice.
- Check regulator vents to be sure they are not clogged.
- Clear snow and ice from all outdoor vents, chimneys and flues.
