Hi do you know if/when this heater will be back in stock. I have a customer in need of a replacement

This exact heater model is now no longer supplied new by Eberspacher. There are two options available to your customer – If installation uses 75mm id ducting • Have existing unit repaired/reconditioned -all repair parts are still available • Replace heater with later generation M2 D4R, or very latest M3 D4R If installation uses 90mm id ducting • Have existing unit repaired/reconditioned -all repair parts are still available • Replace heater with later generation M2 D4L, or very latest M3 D4L The later generation heater options would require further discussion as they are not a straight swap, they require different harness connections plus different controllers. Butler Technik have a real labour saver adapter harness available for this purpose Let me know what you think, quite happy to discuss on a telephone chat 01522 243310 or email support@butlertechnik.com
