Balboa 4.0kW LowFlow Trombone Heater [26"x6"] [240v] (58375T) aquastar Laing Thermotech SM-1212-NH-21-1 circulation pumpLow flow heating systems need components that can deliver temperature support without relying on the same circulation profile used in conventional heater designs. This 4. 0kW trombone style heater is built for that type of setup, giving compatible systems a heating option designed around lower flow conditions. The larger 26 inch by 6 inch format sets it apart from more common heater bodies and makes correct replacement matching especially important.
