Paraffin (kerosene) heaters: These create warmth and give off moisture that will need to escape through ventilators. They are efficient, but if badly maintained and with a wick that is set too high will produce smoke.

Electric fan heaters: Most have built-in thermostats to ensure that the desired temperature is maintained. Waterproof cables and sockets are essential; avoid hot draughts on plants.

Tubular electric heaters: These are controlled by a thermostat. Ensure that the hot air can rise freely.
