One alternative would be teflon heaters. They are not cheap, but would last you a long time.

Dear R.Gowtham,

You can safely replace glass heaters with 316 stainless steel heaters.

Titanium is also good, durable and not too expensive.

Dear Gowtham,

I agree with Guillermo. For electroless plating (acidic bath and high temperature) titanium heaters are more durable. However, they are bit expensive compared to stainless steel heaters.

Depending on your needs, facility, and budget, you could run a Heat exchanger in the solution filtration loop, with boiler supplied steam and a heat exchanger with temperature control/solenoid to maintain temperature...

hai! gautham,
I can understand your problem because I also face the same.
any kind of heater you may use, but use s.s.tank.then use one rectifier apply 2-5 volts.tank should be cathode and put small s.s.rod.it should act as anode.rod should not touch tank.it should immerse only 5% area into the tank.
Please try this suggestion. You will get good result.
good luck
