RY ERSITY A TO OUR TRADE. To meet a demand from certain sections for a heater to carry hot-water radiation, Mr. Pease has recently invented the Heater which is illustrated and described in this circular. A number of them have been set, and we believe that Mr. Pease “budded better than he knew.” The Heater has the advantage of possessing a thoroughly tested construction of one of the heaters which we have been successfully manufacturing during the past ten years. Although it is young it has a sturdy ancestry, and we believe our success in the manufacture of sanitary heating and ventilating apparatus will be a sufficient guarantee for its future success. J. F. PEASE FURNACE CO. CONSTRUCTION. This Heater is cylindrical in shape and of about the same construction as our Low-Down Combination Steam and Warm-Air I Ieater (described on page ii of our 1890 Catalogue.) The Bottom Z, Ash Pit A', Fire Pot Z, Combustion Chamber SS, Feed Chute F , Dust Damper /, and Double Casing T are the same as those used in the construction of the Heater above mentioned. The Hot Water Chambers CCC are flat and round, made of heavy cast- iron (2-inch interior vertical diameter), and are connected to one another by the upright connections DDD. These connections are screwed into shoulders on the chambers and are lock-nutted thereto over asbestos and lead-filled cup joints. These chambers are suspended inside of the com- bustion chamber in such a manner as not to impair the draft, but to retard the exit of the products of combustion until the heat is entirely yielded. The fire exposure is as nearly uniform as it is possible to obtain, and inasmuch as each alternate section extends from side to side of the com- bustion chamber, the product of combustion is forced to traverse over the entire top and bottom surface of each section. The heated gases and smoke ascend alternately around the sides of the smaller chambers and through four flues near the center of each of the larger sections until the exit flue A is reached, where they pass into the smoke pipe several degrees cooler than from any other hot-water heater made. In this Heater the water circulation is positive and continuous. The returns may enter the lower chamber on any side of the Heater which may be most convenient, and the water circulates upward through every portion of the interior of each chamber before reaching the distributing feed pipe, passing as many times over the fire as there are sections used. • ADVANTAGES . 5 DOUBLE CAPACITY. The primary advantage embodied in this Heater is one which has been a large element in making a popular reputation for our Combination Steam and Warm-Air Heater, and that is a Double Capacity for producing Direct and Indirect Heat. The Indiretfl Heat is produced by taking the air from the outside through the cold-air duct Y, and passing it through the air-heating cham- ber A r NNN' in the same manner as by a Warm-Air Furnace. The air is properly heated, moistened by water evaporation (from a vapor-pan not shown in cut), and is distributed through the warm-air pipe OO to the registers in the principal apartments nearest to the Heater. The Direcft Hot-Water Radiation is obtained by a continuous circulation of water, which passes into the lower chamber C, and then on being heated passes up through each of the corresponding sections and through the feed pipes to the radiators, where the heated water radiates its heat and by natural gravity returns to the lower section of the Heater to be reheated. VENTILATION. It is from a knowledge of the fact that our Combination Systems of heating provide a means for perfect ventilation, that we are enabled to claim for this Heater a decided superiority over any All-Hot-Water Heater. Where proper exit ventilation is provided, as a natural consequence our Combination Hot-Water System ensures a circulation of fresh warm air throughout the building. We believe that the atmospheric condition in a house heated by our Combination Heaters is greatly superior to that in a building heated by direct hot-water radiation only. The latter system provides no means for furnishing a fresh air supply ; it simply heats the air in each room many times over. It is a well recognized fact that such methods of heating exhaust the oxygen and render the air impure and unhealthful. RADIATION. There are two features in the ordinary All-Hot-Water Systems of heating which form important objections to such methods. We assume and believe that separate indirect radiation with an all-hot-water plant is impracticable, and hence we draw our comparisons with the Direct System. The first of the objecftions mentioned is the acknowledged fact that to secure the same amount of heat that can be obtained from a given amount of steam radiation, an increased amount of radiating surface is recpiired — usually from 50 to 75 per cent. more. This necessity naturally adds a large amount to the first cost of the plant, to make no mention of the larger space occupied by the radiators The second objection is, that with Direct All-Hot-Water Systems there is, more frequently than otherwise, a necessity of locating the direct radiators in the most conspicuous places in the first floor rooms, where they invariably conflict with other and more ornamental articles of furniture. This is an objection to which the house-wife never becomes reconciled. In the use of our Combination System of Hot-Water Heating these objections are entirely eliminated : Because — the indirect heat from the furnace proper is passed up into the main lower floor rooms through registers sunk in the floor, obviating the necessity of direct radiators in the principal rooms, and naturally making the cost far less for our system than for a plant which would necessitate from 40 to 60 per cent, more radiating surface. We will bring our argument down to a practical application, and cite some figures which we believe will be found reliable and equitable. For example : given, to heat a library of 20 x 20 feet, 10 feet high — 4,000 cubic feet. Figuring close and assuming that the room is well protected, it would require at least 100 feet of direct hot-water radiation (occupying a floor space of 5 feet by 3 feet high. This, with the necessary valves, in an estimate would cost the purchaser from $40.00 to $45.00. To heat the same space from the furnace proper, a 12-inch tin pipe of average length and a 12 x 15 nickel-plated register and border, with box, etc., would be necessary, the cost of which to purchaser would be from $10.00 to $12.00. (These figures u r ould be lessened by using japanned registers.) We submit that it is fair to state that a minimum saving of $25.00 per room is guaranteed for every room heated by indirect heat in the use of our system. A SIGNIFICANT FEATURE. We claim that in our construction the boiler surfaces are exposed to the highest degree of heat which the combustion produces , and in such a manner as to render no portion of the exposed chambers waste surfaces. A consistent retention of the heated gases and smoke, is effectively accomplished. The smoke and oases finally find exit through the smoke flue after yielding O j O J o their heat. In our experience two classes of heaters have frequently come under our observation in which two conditions entirely opposite to one another have made them obviously inefficient in the power of economically producing heat. In the one — taking cheap direct-draft heaters, for example — the smoke and gases having a too free access to the smoke flue only exert their forces to heat up the flue, promote a stronger draft and create an ineffective combustion. This class only proves suc- cessful in the coal-dealer’s point of view. In the other — taking for an example a class of heaters which force the product of combustion several times around the heater in an unnatural course — the struggling contra forces maintain a low state of combustion which is entirely inadequate to heat the chambers. The radiating surfaces are apparently uniquely arranged to absorb the heat, but a disregard for the requirements of natural law prevents effective results. A technical examination of our apparatus will reveal a con- sistent distribution of boiler and radiating surfaces. Purchasers can to an undisputed degree of certainty expect a maximum of result from a mininunn of expenditure. AVERY USRARY COLUMBIA UNIVERSITY DEFINITE REASONS Why our Combination Heater Merits Careful Consideration, and Why we Claim that it Approaches Nearer to Perfection than any other Hot Water Heater. 1. BECAUSE p roper facilities for ventilation are assured to the purchaser. 2. BECAUSE our system requires much less radiation than Direct Hot-Water Systems. 3. BECAUSE it precludes the necessity for direct radiators where they are not wanted. 4. BECAUSE the fuel consumed is entirely utilized in producing heat. 5. BECAUSE it is easily cleaned of the natural accumula- tion of soot. 6. BECAUSE it can be adjusted to heat windward and distant rooms, which warm air from a furnace could not reach. 7. BECAUSE its capac ity for hot-water radiation can be regulated to suit the demand. 8. BECAUSE no more fuel need be consumed at any time than is necessary. 9. BECAUSE the fu ndamental principles employed in its construction are based on nearly forty years of practical ex- perience in Warm-Air and Combination Heating, and because it possesses all the advantages of the indirect heat-producing portion of our Combination Steam Heaters, which have been a great success ever since they were introduced in 1882.
