4 Mistakes to Avoid When You Buy a Gas Heater or Portable Gas Heaters for Sale
The gas heaters for sale may not be the right ones to buy. When it’s time to buy a new gas heater for your home, you want to make the right choice.
There are some common mistakes that many people make, when they buy a gas heater.
You can sidestep these slip-ups by being informed.
LPG Gas Heaters & Natural Gas Heaters
LPG gas heaters and natural gas heaters are both energy efficient and a wonderful way to heat your home. Gas heating is rapid and provides true warmth. LPG heaters are well suited for open floor plans and provide toasty warmth to all parts of your home.
Gas Heating - How to Find the Best Gas Heater for Sale
Avoid these four typical mistakes and you should end up with a brilliant gas heater buy that impeccably suits your home:
1. Choosing the wrong fuel
2. Selecting the wrong type of gas heater
3. Getting the wrong size gas heater
4. Paying too much when you buy a gas heater
1. Choosing the Wrong Fuel Type
There are two types of gas heaters for sale, LPG and natural gas. Gas heaters are manufactured for use with only one gas type and will not work safely with other gaseous fuels.
You need to make sure you buy a gas heater model that is made for the type of gas you have at your home. Always double check that the gas heater for sale is the right fuel type.
There are two main differences in the way that LPG (Propane) and natural gas (Methane) are burnt.
The first difference is in the energy content.
LPG has a higher calorific value, or energy content, so less gas is required to produce the same amount of heat.
The second difference is in the oxygen to gas ratio required for proper combustion.
LPG requires an oxygen to gas ratio of approximately 25 to 1.
Natural gas requires a ratio of around 10 to 1.
To achieve this difference, LPG is typically provided in a smaller quantity but at a higher pressure, drawing more oxygen with it into the burner.
Never attempt to connect a gas appliance to the wrong type of gas, as it can be extremely hazardous.
Buying a new or used heater with the intention of converting it can be very expensive, assuming conversion is even possible for the model in question.
This option is best avoided.
2. Buying the Wrong Type of Gas Heater
Gas heaters are broadly grouped as either Portable (unflued) gas heaters or Flued heaters.
Within these gas heater groups are sub-groups for sale including radiant, convectors, radiant-convectors, power flued, flued radiant and wall heaters.
Radiant gas heaters warm you much like the sun.
Radiant heaters allow specific spaces within an indoor area to be heated, primarily warming only the people and objects positioned in front of the unit.
They also come in smaller sizes for minor heating applications.
Radiant heaters are generally not suitable if you want even heating within a larger space.
Think of them more as spot heaters.
Convector (Convection) heaters warm your space using convection or air movement.
Along with the gas burner, they incorporate a fan to help distribute the heat more evenly throughout the space.
Convectors are also sometimes referred to as Space Heaters.
Fan driven convection heaters are much more suitable for larger spaces, doing a much better job of even heat distribution than radiant heaters.
However, if you only wish to heat a small area within a larger space, these may be more than you really need.
You should also consider if you want to buy a flued or an unflued gas heater.
For the majority of people, unflued heaters are quite safe to buy when you follow all of the manufacturer’s safety instructions, including providing adequate ventilation.
Care should be taken when using an unflued gas heater if the family includes very young, unborn, elderly or individuals with some medical conditions, as they may be more sensitive to the emissions.

3. Buying the Wrong Size Gas Heater
Once you pick your type of gas heater to buy, you will also need to decide what size unit you need, as each type comes in various heat output models.
If you buy too small a gas heater, it will not be able to adequately heat the intended area.
If you buy a gas heater that is too large will cost you extra money and oversizing can be unsafe.
Remember, the heat output of the gas heater is measured in kW, not to be confused with the gas input, expressed in Mj.
