Proof of concept testing of low swirl burner for on-demand water heaters

Although on-demand water heaters are 37% more efficient than storage water heaters, they are significantly more expensive. The increased cost results from use of multi-stage burner banks that require complex electronic controls. Lawrence Berkeley National Laboratory's (LBNL) Low Swirl Burner (LSB) could reduce burner complexity for these appliances. Manufacturing costs may be reduced if LBNL's LSB technology is successfully applied to on-demand water heaters. LBNL performed laboratory testing to confirm the technical suitability of the LSB for on-demand water heaters across relevant product specifications.
