The business of any hotel or restaurant should not be limited by the vagaries of nature. Spring and summer is a time for opening up the lawns, gardens and the patios for the guests. This results in a high volume of business turnover. On the other hand during winters, the whole outdoor infrastructure has to be shifted indoors due to the cold.Since the space in a hotel or restaurant is limited, it often results in decreased sales. The only solution for the hotel owner then is to make arrangements to keep the clients round the year and carry on as usual. For this he has to arrange for some heating gadgets.
