Putting the Sun at Work in the House 



All that is necessary is to expose the pipes so that the 

 genial rays can reach them. There is no charge for service

The usual location for the heater is on the roof of the 

 house; but it is sometimes over a driveway per- 

 gola or above a window. At right: The sun-coil

THE people of Southern California are 

 letting the sun provide the warmth 

 whereby the water they use is heated. 



The device by which it is done is known 

 as the "solar heater." It consists of a 

 shallow box about four inches in depth, 

 within which is a coil of galvanized water 

 pipe. The box is covered with glass and is 

 practically air-tight. A 

 sheet of copper is placed 

 behind and attached to 

 the water pipes for the 

 purpose of concentrating 

 all of the sun-heat falling 

 upon an area several times 

 larger than that offered 

 by the pipes themselves, 

 thereby making the water 

 correspondingly hotter. 



The pipes of this heater 

 are arranged with a certain 

 upward pitch so that the 

 heated water gradually 

 passes from the coil to the 

 storage-boiler. As the hot 

 water leaves the coil its 

 place is taken by the 



FLASHINO 



The storage-boiler is encased 

 in an insulated wooden box 



coldest water from the storage-boiler. Dur- 

 ing warm, sunny weather the water that 

 was first heated and sent to the storage- 

 boiler will return to the sun -coil to be 

 heated to a still higher temperature. This 

 storage-boiler is encased within a wooden 

 box and the space between 

 the boiler and the sides of 

 the box is filled with a 

 heat-retaining packing. 

 The loss of heat by radia- 

 tion is very slight. Assum- 

 ing that no water is drawn, 

 the loss of heat due to radia- 

 tion during the night will 

 vary from four to ten 

 degrees. Hence, hot water 

 can be drawn in the early 

 morning as well as at the 

 close of a sunny day. 

 From this tank the heated 

 water passes to the various 

 fixtures of the home. 



When the sun fails to 

 shine a gas-heater is used.
