So far as can be determined from 

 the data given, there will be no diffi- 

 culty in heating the residence from the 

 greenhouse boiler, provided the jQjLof 

 the boiler is two to three feet below 

 the surface of the ground. Especially 

 if radiators are to be placed on the 

 second floor of the residence, it will be 

 .advisable to place the expansion tank 

 in the dwelling, above the level of the 

 highest radiator. If in the attic, or in 

 an exposed place, care should be taken 

 that the water in the tank and the 

 pipe leading to it are not allowed to 

 freeze, as otherwise serious results 

 might follow. The pipes leading to the 

 dwelling should be wrapped with 

 asbestos or other good pipe covering, 

 and enclosed either in a wooden or con- 

 crete conduit. Unless more than two

 be placed over the pipes. 



I would not think of heating the 

 greenhouse for lettuce, under the con- 

 ditions mentioned, with less than ten 

 2-inch pipes, and would p r efer to tise 

 a 2V^-inch flow on each plate and four 

 or five 2-inch returns under each side 

 bench or on each wall. The present 

 number of pipes would barely be suffi- 

 cient for 40 degrees in zero weather, 

 except with heavy and wasteful firing.
