Velo Circulating Pumps for Outdoor Wood Boilers

Velo circulating pumps are designed to efficiently move hot water from an outdoor wood boiler to your home, offering dependable performance across a range of distances. Each model in the lineup is tailored for a specific application size, making it easy to choose the right pump for your needs. The Velo 50 is ideal for homes located up to 50 feet from the boiler, providing reliable circulation for shorter runs. For medium-distance setups, the Velo 100 steps up with the capacity to handle up to 100 feet. Meanwhile, the Velo 150 is the go-to choice for long-distance applications, delivering powerful flow for homes up to 150 feet away. No matter the distance, all three models offer the same core functionality—circulating hot water efficiently to keep your home warm and comfortable.
