ONE OF BOSTON'S WELL KNOWN GROWERS 



The Kroeschell has taken the place of four cast iron boilers at a big saving in coal. 

 We are using it now for the fifth year. Tne longer we use it the belter we like it.

PIPING NEEDS READJUSTMENT. 



I have three connected greenhouses, 

 each 22x75 and eleven feet high to the 

 ridge. There are two feet of glass and 

 three feet of boards iu the side walls. 

 The south end of the houses is glass; 

 the north end adjoins the workroom. 

 I should like to keep a temperature 

 of 60 degrees in zero weather. At pres- 

 ent there are in each side house six 

 2-inch flows and seven 2-inch returns, 

 and in the middle house three 2-inch 

 flows and three 2-inch returns. The 

 boiler is large enough, but I could not 

 maintain a temperature of 54 degrees 

 in cold weather, though the water in 

 the boiler was at 242 degrees. Kindly 

 tell me whether there is sufficient ra» 

 diation in the houses for this New 

 York climate. If not, how much addi- 

 tional piping will be required? A. H. 



For heating the houses with hot water, 

 using an open tank system, the radia- 

 tion is insufficient, and the addition of 

 three returns in the outside houses and 

 six in the middle house would be neces- 

 sary to maintain the femperature de- 

 sired in the coldest weather. It is 

 stated, however, that a temperature of 

 242 degrees in the boiler will only main- 

 tain 54 degrees, from which it is evi- 

 dent both that the system is a closed 

 one and that the circulation is ex- 

 tremely pooV, as with the water in the 

 boiler at 242 degrees there should be 

 no difficulty in securing 70 degrees, and 

 «ven more, if the water circulates 

 freely. 



Having this in mind, I would suggest 

 a reaidjustment of the system, especially 

 as I would advise putting in more pip- 

 ing at any rate. A good plan would 

 be to put in three 2% -inch flow pipes 

 in each house, placing one about two 

 feet below the ridge and one of the 

 others on each plate. In the outside 

 houses, twelve 2 -inch returns would be 

 necessary, with nine in the niiddle 

 house. One-tb4rd of the returns should 

 be open each wall and the others under

the middle benches. If, for any reason, 

 it is inadvisable to have pipes under 

 the center benches, or in the walks of 

 the middle house, it would answer if 

 one 2^^-inch flow pipe is carried on 

 each of the plates and five returns upon 

 each wall underneath, v 



If tha top of the boilfr is below the 

 level of ''the walks, it "wtnlhJ not be 

 necessary to make use of circulators or 

 other methods of securing a closed sys- 

 tem, but if this is not the case a closed 

 system is desirable.

I should like to get your advice in 

 regard to the piping of the three houses 

 shown on the enclosed sketch. In this 

 part of Alberta, Can., the weather be- 

 comes decidedly eoli at times, with the 

 temperature occasionally as low as 35 

 degrees below zero. We wish to main-
