Oct 31 2014 · Tankless retrofits almost always require a gas pipe size up- grade. A typical 40-gallon gas tank-type heater uses approxi- mately 40000 Btu per hour. The standard tankless heaters are rated at 199000 Btu per hour! The branch and main lines must be considered if a tankless heater is being added.

Learn MoreThe capacity of a low pressure natural gas (less than 1 psi 6.9 kPa) pipe line with a small pressure loss can be calculated with the Spitzglass formula. q = 3550 k ( h / l SG) 1/2 (1) where . q = natural gas volume flow (cfh) h = pressure drop (in Water Column) l = length of pipe (ft) k = [d 5 / (1 + 3.6 / d + 0.03 d)] 1/2. d = inside diameter pipe (in)

Learn MoreShort restrictions in pipe diameter have far less effect on the flow resistance than long runs at the restricted diameter. So it is quite common and acceptable for a high gas rate appliance such as a combi boiler to require a 22mm copper pipe for the majority of its gas feed and yet the boiler to only have a 15mm inlet connection.
