visable to have the top of the boiler 

 two feet below the returns, if possible, 

 as there would then be no trouble about 

 returning the water to the boiler. In 

 case steam is used, a trap would be re- 

 quired if the boiler is higher than the 

 returns. 



For heating one of the houses with 

 hot water, use three 2i^-inch flow pipes 

 and twelve 2-inch returns. One of the 

 flows can be about two feet below the 

 ridge and the others can be placed 

 on the walls, or one can be under the 

 ridge, another on the front plate and 

 the third under the purlin. Distribute 

 the returns on the walls as evenly as 

 possible, but do not connect more than 

 five returns to one flow pipe. Give the 

 flow pipes a slight fall and connect 

 the expansion pipe at the highest 

 point, which will be near the boiler. 

 The tank need not be a great distance 

 above the flow pipe, but an elevation 

 of eight or ten feet will be desirable. 



If steam is to be used, carry a 2-inch 

 flow under the ridge and distribute 

 ten 1%-inch returns on the walls. 



A HOME-MADE HEATER. 



I am erecting a double house, each 

 section of which is 21x60, with the cen- 

 ter wall skeleton or open. The height 

 to the eaves is four feet six inches. I 

 shall use liot water for heating and 

 wish to get information as to the plac- 

 ing of pipes to heat these two houses 

 eflfectively from the same heater. I 

 am thinking of building my own fur- 

 nace, making it of fire-brick and heat- 

 ing the water from a coil placed inside. 

 Can this be done with success? What 

 size of pipe should be used? I expect 

 to use both solid and raised benches. 

 My main crops will be lettuce and to- 

 matoes. I can connect with the city 

 water supply. My location is western 

 Oregon. " H. K. M. 



While coil boilers are sometimes 

 used, it is generally better to procure 

 one of the greenhouse boilers now on 

 the market. It will be best to use 

 2-inch pipe in making such a boiler, 

 and- to put about one-twenty-fifth as 

 much pipe in the boiler as will be 

 needed for radiation. Something over 

 1,000 square feet of radiation will be

Condensation is the pnreet Itind of boiler feed water. Don't waste it. Return it directly to the boiler 

 by "Detroit" Return Traps and prevent scale formation.

ITwo Tank Traps vs. One Tank Traps 



I The flsed tank on the EogUsh Trap does not 

 move, with Its lanre body o( water. We overcome 

 the objections to the tilting Trap by carrying tbe 

 weight of the Eoffllsh Trap on special fltting^, and 

 not on the tranaions, as in all otlier ttlting traps.
