Greenhouse Heating 



Subscribers are invited to write the 

 Editor of this Department with regard to 

 any details of greenhouse heating that 

 are not understood. But please do not 

 ask The Review to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this paper is, we 

 believe, the best lor the trade to buy, and 

 each article the best in the special field 

 of its adaptation. 



TO REMOVE TAB FROM PIPES. 



Last September we painted our hot 

 water pipes under the gutter with gas 

 tar to keep them from rusting. The tar 

 seems to be dry, but when the water 

 in the pipes is heated to 160 degrees 

 the tar gets soft and gives off fumes 

 which are spoiling the lettuce crop. We 

 have tried whitewashing the pipes, but 

 this does not help much. Scraping the 

 tar off is slow work. Is there any- 

 thing we can put on the pipes to keep 

 the fumes from escaping? We did not 

 know when we put on the tar that the 

 fumes from it would be injurious to 

 plant life^ but we have found it out 

 since. J. H. S. — ^la. 



It is known that gas tar must not 

 be used where plants are grown under 

 glass. Even when tar is applied to 

 the posts or gutters, serious effects are 

 noticeable, and when it is used upon the 

 heating pipes it will be impossible to 

 grow plants with any degree of success. 

 Worse yet, there is no known way of 

 treating the pipes that will prevent the 

 giving off of the poisonous gases, except 

 the removal of every atom of the taj. 



The only way to correct the trouble 

 is to burn off the tar, and care must be 

 taken to do a thorough job and still not 

 to injure the piping. It can be done 

 easily and quickly by taking down all 

 pipe that has been coated with the tar 

 and building a fire of old posts, or other 

 refuse, three or four feet across. In 

 this fire the pipes should be held until 

 the tar has been burned off. 



By inserting smaller pipes eight or 

 ten feet long in the ends of one of the 

 tar-coated pipes, it will be possible for 

 two men to bum off the tar without 

 injuring the pipes. The pipes should 

 be turned and moved back and forth in 

 the fire to prevent overheating. 



While we have never used coal for the 

 purpose and would prefer wood, in case 

 the latter is not available it is probable 

 that soft coal could be used successfully 

 and safely for maintaining the fire. 



When treating pipes of large size, 

 the work of holding them may be les- 

 sened by placing two short pieces of 

 pipe on either side of the fire at right 

 angles to those to be treated, upon which 

 to rest them. These supporting pipes 

 may be arranged to act as rollers to aid 

 in moving the pipes back and forth 

 through the fire. 



A LEAK-TO« HOUSE FOB VIOLETS. 



Please state the number of feet of 

 2-inch piping that will be required to 

 heat a lean-to house 7%xl00, attached to 

 the side of another gp-eenhouae and fac- 

 ing north. Hot water heat will be 

 used. The house is five feet high from 

 the ground level to the gutter. The 

 wall is formed of ship-lap siding. The 

 rafters are eight feet long and the

THE REWARD OF MERIT 



VISIT THE CLEVELAND GROWERS 



The Kroeschell is used by the leading florists in this section of the country, 

 and mighty is their praise. The Kroeschell is making the most wonderful 

 greenhouse heating record in Ohio. We invite you to call on any of our 

 customers and will be pleased to have you put the question point-blank: 

 "What do you think of the Kroeschell and why have you ordered same again 

 and again?" 



ORDER YOUR BOILER NOW 



Building has been suspended during the war, but it 

 will boom soon to make up for lost time. We 

 believe that building materials, INCLUDING 

 BOILERS, can be bought cheaper now than later, 

 after the building boom gets under way.
