Flued Gas Heaters vs Unflued Gas Heaters - Flued Gas Heaters vs Portable Gas Heaters

Flue configuration diagrams

Unflued gas heaters have no flue and discharge the combustion gases and water vapour directly into the home. Most unflued gas heaters have a hose and bayonet fitting so it can be moved from room to room, plugged into bayonet sockets.

Unflued gas heaters have higher energy star ratings but they do vent some combustion gases inside the home. The gas levels released are specified by government safety regulations.

Flued gas heaters for the home have a flue that conveys all combustion gases and water vapour outside of your home, for cleaner indoor air. Balanced flue models draw the combustion air from outside your home, so the amount of air drawn in is balanced with the exhaust gas that goes out the flue.

Flued gas heaters burn gas to generate heat and use a flue to carry the exhaust gases away. You can get either flued gas space heaters or flued gas fireplaces. There are both natural gas and LPG flued gas heaters.

Unflued gas heaters are more energy efficient and cost less to purchase and install than flued gas heaters. (see flue diagrams above)

LPG Freezing Point: Propane Tank Regulator Freezing - LP Gas Regulator Freezing

LPG (propane) freezing point is -188 °C (-306.4°F). This would only ever occur under laboratory conditions. There is no place on the planet where temperatures this low occur in nature.

LPG-propane does not freeze in winter.

LPG-propane BOILS at -42°C (-43.6°F), which means that liquid propane does not vaporise - turn to gas - below that temperature. So, unless you live in Antarctica, you should have no problem.

The causes propane tank frost and propane regulator freezing are the same. Under the right circumstances, condensation, ice or frost can form on a propane tank (LPG gas bottles) and a propane regulator freezing but the LPG gas does not freeze.

Does LPG Gas Freeze in Winter

In answer to the question, "No, LPG gas does not freeze", as the freezing point is at -306.4°F (-188 °C). However, what many really want to know is if the LPG-propane tank ever gets too cold to work. The average winter temperature at the South Pole is about -56.2°F (-49°C).

LPG does not freeze in the winter. And if you get propane, and you don't live in Antarctica, it should work fine. However, if you get butane and the temperature drops below freezing, the butane will stop vaporising.


Propane Tank Frost

Propane tank frost is a result of the vaporisation process, when the liquid gas draws heat from the steel walls of the tank to boil and vaporise. This make the tank walls cold, as the boiling occurs at -42°C (-43.6°F). Combine this with some ambient humidity and the result is propane tank frost.
