RIDGE AND FURROW RANGE. 



I see in the Review some very inter- 

 esting articles on steam and hot water 

 heating of greenhouses. I intend to 

 change my system from gravity to the 

 use of a steam trap and would like to 

 know what is the best plant Our houses 

 run east and west, 14x120, all connected 

 as one large room, no partitions; six feet 

 headroom at the lower end of tlie gut- 

 ter; about seven feet at the higher. end. 

 Our boiler is in a pit six feet deep. 

 Our radiation pipes at present are high 

 above the beds. 1 wish to ^t them un- 

 derneath. Our boiler is ' located at the 

 northwest corner. There is about eight- 

 een inches slope of the ground towards 

 th« boiler. 



Is it better to run a riser or main un- 

 der each ridge to the east end, and then 

 lower, divide and return under the 

 benches f Or divide th6 radiation as 

 soon as it comes in, right at the west 

 end, and jo.n the pipes at the east end 

 into two returns, and return to the con- 

 densation tank? How many lineal feet 

 of 1*4 -inch pipe will be required to heat 

 the plant in weather 10 degrees below 

 zerot 



I prefer not to tun a riser if it can be 

 avoided. I would much rather distribute 

 the steam direct from the main at the 

 west end, and connect the pipes at the 

 farthest end into two returns, if this 

 will work. P. B. 



Can you not lower your boiler so as 

 to maintain the plant on a gravity sys- 

 tem? If you can it will save much 

 trouble. 



I am sorry I cannot commend the 

 plan of piping you prefer. It has been a 

 regret to have to remodel several houses 

 piped as you suggest because it was im- 

 possiDle to maintain the temperature in 

 the two ends of the houses within 15 

 degrees to 20 degrees the same. No dif- 

 ficulty in this respect, however, ever has 

 been experienced when a riser was car- 

 ried under the ridge to the most distant 

 point in the plant and the division to 

 supply the radiation made at that place. 



You neglected to state the number of 

 houses in your range. 1 can, therefore, 

 only state the requirements of a single 

 house. In computing the requirements 

 for a ridge and furrow plant such as you 

 have it is our practice to deduct a per- 

 centage from the radiation as computed 

 for independent houses, which I cannot

This is a sample of letters we receive from our customers. "Bums Boiler Co., Green Bay, Wis. 

 Dear Sirs: Replying to your letter of the 2nd inst., r^arding your Eclipse Boiler I installed in my green- 

 houses two years ago, will say that the boiler is givi g me best of satisfaction. At the same time I 

 installed your boiler, I built an addition to my greenhouses with about 8000 sq. ft. of glass, and the first 

 winter I saved 175.10 in fuel. This is a very large saving whtn you consider that I hmlfd 8000 sq. ft. 

 additional glass and at the same time saved t76 00 on fuel, and if I were to install another boiler, I certainly 

 would have no other than your Eclipse." Yours truly, LOUIS OTTO, Neenah, Wis., Aug. 11, ia06.

Gentlemen:— You can strongly and unhesitatingly recommend the 

 " Eclipse " piston type reducing: valve to florists. We have two purchased 

 of you last year. We would not have them out for double their cost and 

 find them as sensitive as a watch. We will be in Chicago soon to take ap 

 the vacuum system with you. Yours truly,

flo in this case because the number of 

 houses is not stated. 



It will be a safe plan to run a 2-inch 

 riser under the ridge of each house and 

 return by seven 1^4 -inch pipes in each of 

 the inside houses and eight 1^-inch 

 pipes in each of the outside houses; i. e., 

 in the houses having the exposed outer 

 wall, locate the extra pipe in each case 

 near the exposed wall. L. C. C. 



HOUSE ON SIDE HILL. 



We have a side hill facing the south 

 which could be trimmed down to an 

 angle of 32 degrees, the same pitch as 

 the greenhouse roof. The house is to be 

 60x100, rafters six and one-half feet 

 from the ground. It will be ventilated 

 on the north and on the south side by 

 sashes in the wall. Coldframes running 

 along the south side will give additional 

 support to the house. The heating will 



have to come mostly from the lower end. 

 How should we pipe for best results, 

 using a combination, steam and hot 

 water? The house is to be used for 

 forcing early vegetables from February 

 1 to May 30, the outdoor temperature 

 going 10 degrees below zero at times. A 

 ten horse-power return tubular boiler 

 will be used. Will it be large enough? 



A. M. 



Thirty-two degrees is a good angle for 

 a house to be used for forcing vege- 

 tables during the season mentioned in 

 the latitude of Ohio. 



If you wish to use a combination 

 heating system, I think it would be well 

 to locate the boiler in the center of the 

 lower side and carry the main supply 

 pipe through an alley running up the 

 hill through the middle of the house. 

 The flow pipe can be arranged, say two 

 feet off the ground, and the return on
