Unflued Gas Heaters

How many people would put a water mister  in their living room when it is 5 degrees C? Added to this how many would want sleep inducing poisonous gases to be emited by the same machine? This is excatly what they are doing when they use an LPG portable gas heater. I cannot find a valid reason as to why portable gas heaters are allowed to be used in New Zealand homes. The only feeble excuse I have heard is that its cheap. Well thats true but the fact that we are gasing ourselves on top of creating mouldy smelly houses just does n't make sense. Almost every other first world country has restrictions or bans on their use and with very good reason. It is the equivalent of lighting a fire in the middle of your tent....it keeps you warm and the the fire wood is free, but your going to have chest problems and stinging eyes from the smoke and gases.
Burning LPG gas creates harmful gases such as nitrogen dioxide, carbon dioxide,  and carbon monoxide the effects of which can be serious enough to kill you. How is the public proteceted against these effects? The manufactureres are made to put warning labels on the appliances. Most other countires require the manufacturers to have oxyygen depletion sensors that will cut off the gas supply. Burning LPG also produces about half a litre an hour of moisture which remains within an unvented room causing damp and mould, all of which are likley to exacerbate any person with asthma conditions.

If your a landlord you should make sure that your lease does not allow the use of these heaters as they are a disaster for your asset let alone the health of your tenant.
