A: Morning Stuart, We can supply a heater like that, we would need more information, but you are normally looking around the 2-3 week mark for these heaters to be made up, regards, Phil.
Q: Hi there, I'm looking for an immersion heater which can have its desired temperature adjusted anytime from the outside (without the need to open the enclosure or cut the power). Do your industrial immersion heaters and digital immersion heaters offer this possibility? Thank you.
