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 for the trade to buy, 

 and each article the best in the special 

 field of its adaptation. 



BOILEB AT GREENHOUSE LEVEL. 



Will you kindly inform me as to the 

 best way of heating a single green- 

 house, 20x60, with steam? The diffi- 

 culty will be to get a good return. I 

 cannot sink the boiler lower than the 

 greenhouse, but can place it about level. 

 Is there any means of helping the cir- 

 culation that is cheaper than the steam 

 trap! I am located in northern Ten- 

 nessee. M. R. H. — Tenn. 



Even in a house of the size of the 

 one described, it is desirable that the 

 water level in the boiler be two feet 

 below the level of the returns. If this 

 arrangement cannot be secured, a steam 

 trap will be found the cheapest way 

 of handling the return water, unless 

 cheap electric power is available, when 

 an electric pump might be used. It is 

 stated that the boiler can be "placed 

 about level." If this means that the 

 top of the boiler will be about level 

 with the floor of the greenhouse, it will 

 probably be possible to use a gravity 

 system if the returns are placed on the 

 walls. 



To heat a house 20x60 feet, without 

 glass in the side walls, to 60 degrees 

 when the temperature is at zero out- 

 side, I would run a 2-inch main about 

 two feet below the ridge to the farther 

 end of the house and there connect it 

 with four 1^-inch returns on each of 

 the side walls, raising them two feet 

 above the water level of the boiler. 



REBUILDINO AND ENLARGINa. 



Will you please give me some in- 

 formation concerning the heating of my 

 greenhouses! I expect to change my 

 location, moving my two greenhouses 

 to the east part of town. The houses 

 are each 25x60. When I rebuild them 

 I shall place them end to end, making 

 a house 120 feet long. The two houses 

 are heated with a Kroeschell hot water 

 boiler. There are twenty-six l^^-inch 

 pipes and thirteen 2-inch pipes, ar- 

 ranged in coils in the two houses. 

 Would it be possible to convert the 

 Kroeschell boiler into a steam boiler f 

 If possible, how should it be- done? 

 Would the present piping be sufficient 

 to heat, with ste^m, the two present 

 houses, erected end to end, and one 

 additional house 28%xl20t The tem- 

 perature in the new house will be for 

 carnations, 50 to 52 degrees at night. 

 I shall use part of the old houses for 

 roses, requiring a night temperature of 

 56 to 58 degrees, or possibly 60 degrees.

Please answer this as soon as possible, 

 as I am figuring now on a steam boiler. 



G. F. P.— ni. 



The Kroeschell hot water boiler can- 

 not be readily changed to a steam 

 boiler. In fact, while steam boilers 

 may be used for hot water heating 

 with more or less efficiency, it is not 

 possible to use hot water boilers for 

 steam heating unless a steam dome is 

 added. 



The amount of piping mentioned 

 would answer well to heat the houses 

 described up to 60 degrees. The carna- 

 tion house may be heated by running 



Come Out on Top! 



Keep your boiler up on the ground where 

 it is readily accessible for firing and 

 repairs. There's a way to save time and 

 money— trouble and expense— and still 

 obtain the same drainage facilities. 

 That way is to install the

 SYSTEM 



The Morehead System keeps your steam 

 lines dry, hot; increases the circulation 

 and assures a perfect drainage. It feeds 

 the condensate directly to your boilers, 

 thereby maintaining the constant tem- 

 perature 80 necessary in the greenhouse. 

 And it's so simple, too— so sure. Ask 

 for the complete facts.
