Greenhouse Heating 



Subscribers are invited to write the 

 .editor of this department with regard to 

 any details of greenhouse heating that 

 are not understood. When information 

 is desired regarding the capacity of boil- 

 ers, or the amount of radiation required 

 for a greenhouse, the needed temperatures 

 should be stated in the inquiry, as well 

 as the amount of glass in the side walls, 

 and the dimensions and general arrange- 

 ment of the greenhouses. It is often 

 helpful, also, to have a sketch showing 

 the location of the houses. 



HEATING TWO HOUSES. 



* We are erecting two connected 

 houses, each 29x100. There arc forty- 

 five inches of glass in the south wall 

 and no glass in the north wall. These 

 walls are seven feet to the gutter. How 

 many lines of 2-inch pipe will it take 

 to heat these houses to 52 degrees in 

 zero weather f How many and what 

 size of flows shall we use? 



N. S. M.— Kan. 



Bun three 2i/.-inch flow pipes in each 

 of the houses, placing one flow three 

 feet below the ridge and the others on 

 the side wall plates. With these flow 

 liipes, supply three coils, each contain- 

 ing four 2-inch returns, in the house 

 having glass in the side wall. Only ten 

 returns will be needed in the other 

 house. The coil containing four re- 

 turns should be along the outside wall. 



TO HEAT TWO HOUSES. 



I have a greenhouse 20 x 80. It is 

 five feet to the plate and ten feet to 

 the ridge. It has two feet of glass in 

 the south wall, with raised benches on 

 the side and a solid bed in the middle. 

 At the west end is a 6-rooin house, with 

 a basement, 24 x 2(5. I desire to heat 

 both these houses. I want to heat tho 

 greenhouse to fiO degrees; the outside 

 temperature runs to 40 degrees below 

 zero. How shall I arrange the piping 

 and what size of boiler will be required 

 if I use soft coal? P. V.— N. D. 



The data regarding the dwelling is 

 not complete, but it is judged two, at 

 least, of the rooms are in the second 

 story, The amount of radiation needed 

 will depend largely upon the number 

 and size of the windows, regarding 

 which nothing is stated. However, we 

 are of the opinion that at least 400 

 square feet of radiation and perhaps as 

 much as 500 square feet will be needed 



Kroeschell Dependable 

 Hot Water Boilers 



How sure are you that your crops will 

 be all right? 



You can never be absolutely sure that 

 nothing will go wrong, but you can feel 

 pretty safe if you have a dependable 

 boiler that will always maintain the re- 

 quired temperature. 



With your houses equipped with a 

 Kroeschell Hot Water Boiler you need 

 not fear that your crops will be hurt by 

 low temperature. Under adverse weather 

 conditions, when crops are in most dan- 

 ger, it is easy to regulate temperatures 

 with Kroeschell Boilers. 



That Kroeschell Boilers are the safest 

 and most economical, has been proved by 

 their country-wide use in large and small 

 establishments, owned by the wisest 

 growers, where only the best of equipment 

 is used, and where the best of stock is 

 raised.

You need not go far to find a grower 

 who has a Kroeschell. Go and see him. 

 After you have talked with him, you will 

 want one, too. Then write us a letter.
