POOR FLORIST Z 



nVO you have to tret up nights to see if 

 IPJ your hothouse is too hot or cold? 

 "^ Don't do it any more ! Let a Ther- 

 mostat be your watchman. It can be set 

 for any desrree and will make a contact on 

 rise or fall of temperature. If it g^ts too 

 cold or warm, a bell at your bedside will 

 tell you the tale.

one 21^,-inch flow and seven 2-inch re- 

 turns should be used. For 50 degrees, 

 leave out two of the return pipes. The 

 flow can be under the ridge and the 

 returns under the benches, as suggested. 

 While it will be better not to at- 

 tempt to use the smaller pipes, if they 

 are well above the heater they could 

 be used, putting in two 1-inch pipes in 

 place of a 2-inch and three 1^-inch 

 for two 2-inch. The boiler should be 

 one that is rated for 225 square feet 

 of radiation. 



THBEE MINNESOTA HOUSES. 



What size of steam boiler will be 

 required to heat three new greenhouses, 

 in which there are 20,000 square feet 

 of glass and 1,000 square feet of con- 

 crete block wall? The place is not 

 especially well sheltered and I have 

 known the outside temperature to be 

 32 degrees below zero here. Boses, 

 carnations and general stock are to be 

 grown. What size of pipe is bestf 

 Would it be a good plan to have a coil 

 under each bench? There are to be 

 four benches in each house, all raised. 

 Should the steam enter the two coils 

 at the end next to the boiler and the 

 other two coils be supplied at the far- 

 ther end of the house? 



How many square feet of glass are 

 figured for each foot of radiation, with 

 the outside temperature 20 to 30 de- 

 grees below zero, to maintain a green- 

 house temperature of 60 degrees with- 

 out crowding the heating system? How 

 many square feet of glass would be 

 figured under the same conditions, if 

 hot water were used? M. G. 



Under the conditions mentioned, it 

 will be well to have a sixty, horse-power 

 boiler. "Without knowing the dimen- 

 sions of the houses, it will not be pos- 

 sible to give any really definite advice. 

 Ordinarily it is best to use 2-inch pipe 

 for the coils in a hot water system and 

 1*4 -inch pipe for a steam-heated house, 

 although if the houses are quite long 

 it might be best to use 1^-inch pipe 

 for steam. While it is a good plan to 

 place a portion of the pipes on the side 

 walls, it is generally desirable to have 

 the greater portion under the benches. 



The plan proposed for connecting the 

 coils with the feed pipes is a good one, 

 but it is not necessary to do so^ ex- 

 cept, perhaps, in long houses. Every- 

 thing considered, there is no better way 

 than to connect the feed pipes with 

 the coils at the end away from the 

 boiler. If hot water is used it is cus- 

 tomary to run one flow pipe on each 

 wall and another under the ridge, in 

 houses 27x125 feet or less. For houses 

 larger than this, it is well to run two 

 •ther flow pipes on the purlin posts.

MOREHEAD STEAM TRAPS 



fl The installation of a Morehead Betum Steam Trap in a 

 ^ Greenhouse is absolute evidence of progressiveness on the 

 part of the florist. 



n It is further evidence of good management, for the " More- 

 ^ head " is an investment in both satisfaction and economy. 

 fl The majoritv of florists are using Morehead Traps. If you 

 ^ are one of the exceptions, it will be to your / 



interest to write us— we will make you a 



Uberal trial offer proposition.

As a rule, a 2-inch or 2i/j4nch flow 

 pipe will answer for a steanl^eated 

 house. 



Ordinarily one square foot of steam 

 radiation will heat six square feet of 

 glass, and one foot of hot water radia- 

 tion will answer for three square feet 

 of glass, if a temperature of 60 de- 

 grees is desired. Under the severe con- 

 ditions mentioned, it would be better 

 to make the figures four and two, re- 

 spectively, although a little more could 

 be carried on a pinch for a short time.
