How to Figure Heater Required Tankless water heating cannot be figured by the customary method as used for tanks. Therefore the following method using the "Demand Unit" is used. This unit has been developed from the result of thousands of installations over six years. Calculation of Demand Units Units Installation No. Comparative Kitchen and bathroom.

For new boilers a factor of safety of 2 sq. ft. per demand unit may be figured. Cast-iron boilers require 4 sq. ft. radi ation for each demand unit.* Water Temperature Line temperatures range from 135 , 600 660 720 840 1000 1500 2000 2500 2400 2700 2900 3100 5400 6400 7000 9000 50 70 70 50 70 224 70 224 224 70 224 224 250 250 270 270 270 270 270 290 290 290 290 290 Note--Put the letter C after installation number if it is a cast-iron boiler. Piping details furnished per request. To estimate the cost of piping same as hooking to tank. to 165. but may be controlled within 15. For hotter water special heater is required. Holby Tempering Regulators are sup plied for more uniform requirements built special for Parkinson Heater. 695 Construction--The Parkinson is protected by Pat. No. 1,834,070 and operates on an ex clusive principle not to be confused with other heating coils. Supply tube and return tubes are sized to produce a rapid and constant flow of hot water. Heater is constructed of virtually pure copper, consisting of heavy wall tubes and cast headers, brazed together, with copper flux at high tempera ture. Installation--Heat ing unit is submerged in boiler water j ust be low water line of prac tically any low pressure boiler. Simple to in stall. Does not multilate the boiler as only one incision is required. Unit takes up no usable space in cellar. Oper ates on any fuel, auto matic or hand fired.
