Natural Gas 75 gallon	$85.00	$35.00	-0-	$200.00	$175.00	$470.00
Natural Gas 75 gallon, Direct/Power Vented System	$95.00	$35.00	(1) $40.00*	$200.00	$175.00	$545.00

* Tankless Water Heaters: Four (4) - 240 volt circuits @ $30 each. Here, the cost of the four circuits was estimated to be lower than in the following electric 50 gallon tank heater because of the low cost of material and ease of running the extra circuits.

Electric Storage Tank: A single 240

volt circuit. Typical price for single 240 amp

circuit. Same is true for an electric dryer circuit.

Natural Gas 50 gal. Direct Power Vented: A single 120-volt circuit.

Natural Gas 75 gal. Direct Power Vented: Same
