Does it take more power to pump water with a 1 /12 hp bg motor/pump than one that is a spare pump/motor running dry,not connected to the system? I am trying to figure out how long it will run with an power inverter during a power failure.
need the model of pump then i can see how meany watts it uses and tell you how long it will run on a inverter and i also would need the battery cca or if it is a upc back up unit. and they will use a small amount more when they are moving water due to head pressure and friction in the pump and pipe. get me more info and we can figure it out.
Your Bell and Gosset pump runs on 110 volts and circulates the water through the heating system. It will not run dry because the motor is seperate and spinning an impeller.I don't understand what you are trying to accomplish.
Hi there, Your 1/12 HP motor will draw 0.52 amps at 110 volts from the inverter. It would draw about 5 or 6 amps from the 12 volt battery to produce the 0.52 amps from the inverter. You need to know the amp-hour rating on your battery then divide that number by 5-6 to get an approximate time the pump would operate on backup. Yes a pump that is pumping water will draw considerable more power than a pump that is pumping 'dry'. The best way to check is to just try your setup and see how long it lasts (before it's needed) since there are inefficiencies in the inverter, voltage drop in the wiring and perhaps the backup battery is not new. Manufacturers always are optimistic with their ratings Short answer: try it out before you really need it then you will know for sure. Hope this helps, Al
put in a zone valve that way when the power goes out you can open the zone manually and heat with gravity,as the furnace cools it draws the heat from the top of the unit through the pipes and back to the bottom
