The Florists' Review 



OCTOBEB 21, 191S. 



tiom tiiS ■ main will be nearly one-half 

 as much as will be required to heat the 

 greenhouse, unless the main is insulated 

 with extreme care. While a 4-inch main 

 tnight answer if the boiler shed ad- 

 joined the greenhouse, it will be neces- 

 sary to use a 5-inch main or attach a 

 mercury generator if it is located at a 

 distance of 188 feet. It should be pos- 

 sible to heat the house with a boiler 

 having a rating for 1,000 square feet 

 of radiation, but it will be necessary 

 to have a boiler rated for 1,500 feet if 

 it is 188 feet from the greenhouse, 

 especially if the pipe is carried on 

 blocks above ground. 



It is stated that the basement is 

 about six feet lower than the ground 

 line of the greenhouse, but, without 

 knowing the height of the boiler and 

 the slope of the ground between the 

 boiler and the greenhouse, I cannot tell 

 just how to attach and carry the mains. 

 It will probably be necessary to carry 

 the flow above ground, with a slight 

 rise. The return, which should be of 

 tne same size as the flow, may be along- 

 side it.' The return may, however, be 

 carried below the surface. In either 

 case the pipes should be covered with 

 asbestos insulation, and enclosed in a 

 •concrete or wooden box. If they are 

 above ground, the space about them 

 «liould be filled with some insulating 

 material, such as mineral wool. 



For the returns inside the green- 

 bouse, six 2-inch and six l^^-ii^ch pipes 

 may be used. If only one house is to 

 be heated it will not be necessary to 

 have valves on the mains, but if the 

 returns are arranged in three coils there 

 should be a valve upon one of them, at 

 least. Air valves should be provided 

 at the highest part of each coil and 

 wherever necessary to free the mains 

 from air. In case it is possible to use 

 overhead flow pipes as mains, three 214- 

 inch pipes may be put in, placing one 

 upon each plate and the other under 

 the ridge. Three or four of the returns 

 may then be omitted.

Becanse'of their proven sclentlflcally perfect con- 

 struction. Metropolitan Patented Boilers will beat a 

 frlven amonnt of water quicker, with less fu> I and 

 leas attention than any other boiler on the market. 



The remarkable heatlngr' efflclency and quick 

 steamlnf? qualities of these boilers are due to tbelr 

 large and effective heating' surface. 



Just a few points of Metropolitan Patented Boiler 

 merit:— Smooth, perfect finished castinfirs. Push nip- 

 ple connections. Large Are box. providing ample 

 combustion chamber, and permitting a sufficient 

 charge of fuel to require attention only at long Inter- 

 vals. Deep ash pit, making the removal of ashes a 

 slight task. Large flues, making the boiler easy to 

 clean. Orates that are made for hard usage and long 

 service. And above all, they are Fuel Saving, not 

 Fuel Wasting.} 



We also make soft coal boilers which are smoke- 

 less, and save 50 per cent in coal.
