Starting July 19th, 2021, new US Department of Energy regulations will go into effect. This means that single-speed pumps will likely no longer become available for sale. Single-speed pumps consume a lot of energy and are inefficient. They are also more expensive to use because they have to constantly run at the same speed for 24 hours per day. With minimum efficiency standards being put into place, a variable speed pump will be your best option moving forward.
With a variable speed pump, pool owners can circulate their water at lower flow rates for a more prolonged period without added energy consumption. Variable speed pumps are significantly more efficient than single-speed pumps. Variable speed pumps can be programmed to automatically change speeds throughout the day. They save more energy and operating costs than single-speed pumps. They also have a longer life expectancy than single-speed pumps and operate very quietly. These pumps also have better filtration which can lead to improved water clarity.
