My paraffin heater has never given me problems. Thermostatically controlled electric fan heaters are best. The thermostat means that it only comes on when it reaches a certain temperature. That means it is cheaper to run than anything else. A paraffin heater you need to put on and off when cold. My Greenhouse is too far from the house to make it economical to add electricity to.
