If there are unheated areas in your house that are not used to live in, you should consider installing a special-purpose storage heater.
These small devices are usually indoor propane heaters, that is based on natural gas as a fuel.
Storage heaters are devices which are used to store electricity at non peak load periods of the day i.
e.
when base load electricity is available at low price and can be released during the day or when the peak load demand is present and tariff rates are high.
Heat is usually stored in clay bricks or other ceramic material because of its low cost and high specific heat capacity.
Such heaters are generally indoor propane heaters which are small heating instruments that use pressurized gasses for heating.
Also since propane is a clean fuel releasing minimal amount of gases it forms an ideal storage heater for indoor purposes.
However a good ventilation system is still very important when you are using them.
These heaters can also be mounted on a wall and used safely.
The basic control system of storage heaters involves two controls-one for recording the amount of electricity stored during the peak periods and other to record the amount of heat given away.
These two controls can be adjusted by the user and hence provide flexibility to these heaters.
Apart from it, indoor propane heaters also have easy portability due to wheels attached to them which provide easy mobility.
Also its compact size and structure due to a compact propane tank attached makes it easy to handle.
On exhaustion such compact tanks can be refilled and used again.
These heaters heat up only a specific region of your house or any other indoor place without requiring the load to heat up the entire place.
The place it heats up is generally a non-insulated portion of your home.
However in case of indoor propane heaters certain amount of precautions needs to be taken for efficient working.
The regulators, hoses and nozzles must be compatible with them.
There should not be any open flames within the surroundings of the tank and also the heater can be cleaned once in while with a soap and warm water.
Also if too much of heat is stored inside the heaters then it may have a tendency of gradually losing it and thus wastage of heat and cost incurred in storing it.
Also if insufficient quantity of heat is stored then it may not be sufficient for long winter periods and thus external electricity will have to taken at peak load periods into account and thus raising the overall cost to heat up the room.
Hence an optimum quantity of heat needs to be stored which will make them cost friendly storage heaters.
