What it delivers
The TOPWAY 09020 Hot Water Recirculation Pump is a hot water recirculation pump.
A recirculation pump moves hot water back toward the heater so the far tap runs hot sooner; check that your tankless heater's maker approves the setup.
Use a timer or on-demand control so the heater isn't firing to keep the loop hot all day, and insulate the hot line to the far fixture.
From the listing: connections: 3/4" npt; material: Cast Iron; model: 09020.
The listing gives dimensions of 7 in (L) x 6.5 in (W) x 14.5 in (H), a weight of 5.3 lb and 1x circulation pump; 1x instructions manual in the box.
