Wondering which size pond heater is best for your pond? We can help!

There are several factors to consider when choosing a pond heater. As a general rule, you can expect to achieve a 10 degree increase per 1KW per 1,000 gallons of pond volume over ambient temperature. So for example, you would require a 2KW heater to raise the temperature in a 2,000 gallon pond by 10 degrees. For maximum performance, it is recommended to bypass all waterfall returns and use a pool cover when using any pond heater.
