As yet heating a house by electricity is too expensive and isn’t done except by small comforting heaters which heat one room at a time. These are very clean and efficient and not expensive. HOT WATER HEATING The problem of heating water is of serious dimensions for life without hot water to civilized man and woman is a poor struggle. At present there are on the market, distinct from the usual hot water plant installed in properly built and equipped houses--many different and efficient heaters and boilers. In houses where there is no hot water central plant there can be bought for moderate rates an electric heater which is attached to the faucet in tub or wash basin or sink and through its system of copper coils over which the water flows through, you can get hot water immediately! This needs be but connected to your electric light circuit--outlet or fixture. Then there are large circulation water heaters of electrical contriving which of course has to be separately connected--as the (Wattage) heating unit is rated at about 660 watts! These heaters are of excellent construction, but in most vicinities as yet--electricity is too expensive to use thus. This is controlled from any place in the house, so you need not go down in cellar to start a hot water “anything!” In the best of these it is possible to turn on more heat or less from original source by the use of multiple heat switches. All conductors must be insulated, these heaters should be easily installed. There is possible here hot water without ashes, gas fumes, fire risks--and desired temperature at will! It is a fine hurry device for the sometimes opened country house. In winter it is a boon.

This is a heating unit which is dropped into the water basin, pitcher, tea-pot or what not and attached to electric light bulb very quickly heats your water. GAS The gas heater up to date has been most reliable and efficient. There are many good gas heaters too on the market, which when you turn on the water start the fire! These are rapid and have given very good results. There are many “boiler” heated water schemes--the water backs on gas and coal stoves etc. Then too a very efficient method is using the heat (over) not used in the sectional boiler for heating the house. This is effectively used in auxiliary boilers for heating hot water. Some firms are rightly proud of this contrivance as it is inexpensive, ample and convenient.
