Boiler Piping Flow Pipe Sizing Quality HVAC Heating 101

Boiler Piping Flow & Pipe Sizing - It is important that the correct pump is selected in hot water boiler loops so that the correct velocity is achieved throughout the system. Too much velocity and the system will not be efficient because of Laminar flow issues. Not enough velocity and the correct amount of BTUs will not be delivered throughout

Hot Water Heating Boilers, How to Inspect, Diagnose

Handy rule: multiply the hot water flow rate in litres/minute by the temperature rise in celsius. Divide by 100 and multiply by 7 to get the boiler DHW output in kW. Example: 12 litre/min at 40C rise: 12 x 40 = 480. 480/100 = 4.8. 4.8 x 7 = 33.6kW boiler DHW output.

Hot water is less dense than cold causing it to rise to the top of the system. Water inside the rads cools as it gives up it's heat to warm the house and falls to the bottom of the system where is is re-heated by the boiler and rises to the top again. Old unmodified gravity systems are usually direct, which means the water from the hot taps and

Gravity hot-water heating | Old House Web

A three-story house is the practical limit for gravity hot-water heating. And then there's the size of the pipes. The larger the pipes, the faster the water will flow. This is because large pipes offer less resistance to flow than small pipes. It's also the reason why the old-timers used two supply and two return tappings on their boilers.
