Tech note: When replacing older system heaters, you may need to modify the following:

The original 24-0004-19 heater by Laing is no longer available. The replacement is now a Therm Products heater that you will receive if you order this sku.




Discontinued heater was used in 2004 Islands spas and other hot tubs - there is currently no replacement but we are offering a compatible replacement heater  - special order item. 


Note that the new heater by Therm will not fit around the spa pack and must be REMOTE MOUNTED.

There will be discrepancies between the new and old unit.  

The new heater will have 3 wires, not 2.  Black and White go to the circuit board, and Green goes with the ground wires.
Also, the water connections will not be the same size. Any kind of reducer, such as a small piece of clear pipe set around the smaller connection will correct this.  You would then slip the larger connection over it.
