    Please call us for assistance with sizing your Evo electric in-line heater. These little powerhouse can handle heating water volumes from 1,500-4,000 gallons but of course that depends on a number of factors, primarily your desired temperature differential (Delta t). It is also important to observe minimum and maximum required flow rates and choose a heater that works with your aquatic system.
