Water Heater Dc Pump Vs Ac Pump

The ac quote was for a trane 16 seer for 5750 and the heat pump quote was 6250 for a trane14 seer.

Water heater dc pump vs ac pump. The ac water pump often uses copper clad aluminum coils to achieve a competitive advantage at a low price. An ac system with an inverter won t run for as long because power is lost in converting the dc power of the battery into ac power to run the pump but it will pump at or near its full capacity even when the battery is almost entirely drained. In ac this pump will require 1 1kw s of power running 10 hours per day. But dc pumps last longer than the ac ones.

Dc pumps are practically limited to fractional horsepower by price. In areas where ac electric power is readily available an ac powered pump is by far the best dc pump which in turn pumps water whenever the sun shines or stored in batteries for later use by the pump. Ac water pumps are a lot cheaper particularly as the power rating goes up and indeed many off grid folk use power management to invert and deliver ac rather than use dc for water pumping for economy.

The dc water pump typically uses pure copper coils and more advanced motor technology to guarantee a long lifespan. At the same time a dc motor pump might be more expensive than an ac pump that is made in larger quantities. Also the effective value of an ac voltage is equal to the square root of the average of the squares of the voltage values across the cycle v12 v22 vn2 n. A dc pump might run directly off the panels without conversion to ac.

Ac pumps are the power adjustable ones but don t last as long as the dc ones which are just on off. A dc system with a fully charged battery will pump water at 100 of its capacity but as the battery loses charge the pumping capacity will diminish as well. My gas electric joint pse bill runs about 95 in the summer and 250 in the winter. I currently have a 6 year old 80 efficient gas furnace and no ac.

I assumed adding ac was the way to go but i was quoted both an ac and a heat pump. When you should choose bldc pump. Jan 04 2009 1 i recently found out that there are 2 types of pumps ac and dc. The conversion adds some losses costs and components that can fail.

0 707 times the peak voltage of 170 in figure 1 equals 120 v. Lorentz uses a brushless electronically communicated dc motor to power all the pumps in the ps2 range.
