DIN80/DN80/3″NB Flanged Immersion Heater


A conversation about all the specifics of your needs is essential when placing an order for a DIN80/DN80/3″NB Flanged Immersion Heater. Screwed immersion heaters are standardized at 2.25″BSP, on the shelf & readily available for online purchase. However, flanged heater requirements are unique to each job. Therefore, it is always best to talk through your specific requirements.

We can usually turn these Premium Quality, British Manufactured heaters around in 2-3 weeks. If you are losing lots of money due to a dead heater & a lack of forethought in carrying a spare, you can pay a 50% premium for a one week turnaround. We are now more politely calling this the “Distress Price”*.
