Greenhouse Heating. 



^^^^^^^^^ ■ ly . I .. I I - . — ,., I.I, I ,^ 



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 Heview to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this paper is, we 

 believe, tiie best for the trade to buy, 

 and each article the best in the special 

 Held of its adaptation. 



WILL NEED A TAT.T.EB CHIMNEY. 



At present we are using a 17-horse- 

 power boiler of locomotive type to heat 

 a greenhouse 30x80 with hot water. On 

 damp days we have considerable trouble 

 in keeping the water hot, as the fire 

 does not burn well. In cold weather 

 there is no trouble, as the fire then 

 burns briskly. We believe the trouble 

 is due to the chimney, which is brick, 

 2%x3 bricks in width and about twen- 

 ty-five feet in height. Next summer 

 we expect to erect another house, 30x 

 130, and we believe we shall have to 

 use steam for heating, but it is certain 

 that we must have more draft in order 

 to make water boil in damp weather. 

 The chimney connection is 16-inch. 



Would it be best to increase the 

 height of the present chimney. If so, 

 how much extra height will be needed? 

 Or would it be better to tear the old 

 chimney down and build a larger and 

 taller onet We want plenty of draft, 

 as we have no night fireman and we 

 are planning to use an automatic regu- 

 lator to control the steam pressure. We 

 have an electric alarm and attend to 

 the boiler when necessary. We can 

 find no tables containing information 

 on this subject and shall be glad to get 

 your advice. S. & S.^O. 



Prom the description given we infer 

 that the chimney is 12x16 inches inside. 

 This should be ample for a 17-horse- 

 power boiler, carrying 2,500 square feet 

 of radiation, but we would prefer a 

 height of forty feet. This would add 

 sixty per cent to the draft and should 

 make it possible to heat both houses to 

 €0 degrees with hot water. We cannot 

 determine whether the present chimney 

 should be rebuilt or extended.

I wrote to you some time ago, stat- 

 ing that I had diflSculty in heating my 

 greenhouses, and you replied in The 

 Eeview of March 2, page 90, informing 

 me that there was not enough radiation

in the main house and that the flow 

 was especially inadequate. Your an- 

 swer was exceedingly helpful, but I am 

 anxious to get a little more informa- 

 tion. As stated in my former inquiry, 

 I have a hot water heating system. 

 The main house, which is 17x65, con- 

 tains one 2-inch flow, connected with 

 twelve 1*4 -inch returns, six on each 

 side of the house. I also have a lean- 

 to house, 10x17, and a glass-covered 

 room, 10x18, which is located between 

 the greenhouse and the barn. You sug- 

 gested that I substitute two 2i^-inch 

 flows for the present single 2-inch flow. 

 Should the flow pipes be lower at 

 the front of the house than at the 

 rear end of the house, where the boiler 

 is? Can I still use the present 2-inch 

 flow and add a 2V^-inch or 3-inch pipe, 

 running it up six feet above the boiler, 

 connecting it to the present flow and 

 then running it over to the other purlin 

 plate? In that case, would the 2i^-inch 

 or 3-inch flow rob the 2-inch flowf 

 When I install another flow, as you 

 advise, what should then be the size 

 of the main return where it enters the 

 boilert When the houses are properly 

 piped, will my 6-section Lord & Burn- 

 ham boiler have sufficient capacity, or 

 should I procure a larger onef 



T. M. H.— O. 



While it makes comparatively little 

 difference, we prefer to give the pipes 

 a slight fall from the boiler, or toward 

 the front of the house in this case, as 

 at present. We would use two 2%- 

 inch flow pipes, as suggested, since a 

 2-inch flow pipe is not large enough to

supply the return pipes on one side of 

 the house. However, it will answer if 

 two of the returns on that side are 

 connected with a 3-inch pipe on the 

 other side of the house. We would 

 suggest the use of two 2^ -inch flows, 

 and the present 2-inch flow may then 

 be used to bring up the radiation in 

 the glass-covered room. 



As stated previously, the main re- 

 turns should be of the same size, or 

 capacity, as the main flow pipes, and 

 the coils should be connected with the 

 boiler by means of two 2i^-inch re- 

 turns, or, if there is but one opening, 

 they should be united to a 3-inch main 

 return. If the boiler has a grate con- 

 taining approximately four square feet, 

 it should heat the houses easily. 



SIZE OF HOUSE NOT STATED. 



I am writing for some information in 

 regard to heating a new carnation 

 house with hot water. My present 

 carnation houses have no heating pipes 

 under the benches, but I can gain sev- 

 eral feet of space in the new house by 

 putting the pipes under the carnation 

 benches. Do carnations do as well 

 with bottom heat as without itt How 

 many 2-inch flows will be needed over- 

 head and how many li4-inch returns
