can use an electric heater for all or just a portion of your heating for instance you may use solar waste heat or room heaters first and use thermostatically controlled electric heaters as the final temperature control to determine the approximate size heater to order choose one of the three categories then follow the calculation 1 recirculating in a nonflowing system heat is only lost to the surrounding air the temperature difference between the ambient air and the water is the biggest factor also the open area of the tank the amount of agitation and the heat loss through the tank walls should be considered all external pipes filters pumps etc will further cool the water for every 9°f 5°c difference there should be 4 w of heat per gallon 3.8 liters of water elevated uninsulated tanks with a large amount of surface agitation could require as much as 12 w per gallon per 9°f for small glass aquariums use 8 w per gallon per 9°f 2 temperature raising only cool water is used to fill tanks and the water needs to be warmed before the fish are added time and ambient temperature will be considerations for every 1,000 gallons 3,800 liters 1,200 w 1.2 kw are needed to raise the temperature 10°f 6°c in 24 hours this assumes ambient temp is the same as the water 3 flow-through heating a flow-through system has cool water entering and warmed water leaving this is very wasteful and expensive without heat exchangers determine the maximum gallons per minute that you expect and the greatest temperature difference 1,000 w 1 kw will raise the temperature of 6 gallons of water 23 liters one °f 55°c per minute example 6 gpm with a 10°f difference 10 kw heater sizing quick heater sizing guide for non-flow-through calculation it s difficult to simplify something that is complicated but use this quick reference chart to estimate the size of an electric heater a tank with 1,000 gallons is in a room that will stay around 60°f and you want the water temperature to be 87°f if 4 w per gallon are needed for every 9°f then dt 27° 27 ÷ 9 3 3 x 4 w 12 w per gallon 12 w x 1,000 gallons 12,000 w assumes one large uninsulated uncovered fish tank plus one peripheral such as a sand filter and a pump with no extreme water/air interface such as splash aerator or degassing tower minimize heater size and power use by insulating and covering follow the chart to keep the water at desired temperature but if a few degrees temperature loss is tolerable during brief periods of cold weather use that temperature on the chart for more accurate sizing contact our technical
