1500 W electric heater control

I've got a 110V, 1500 W immersion heater (similar to the kind used in
electric water heaters).

I'd like to control it a little more precisely than simply switching
it on/off every 30 seconds.

Is this a good application for a triac?

Thanks,

Michael

A resistive load, sure sounds like it.

Bye.

Eh, I just want to heat up some... uh... liquid to... oh, about 97
degrees Centigrade.

Will I need a snubber?

No, but you'll need a temperature controller.

Build or buy?

It's done all the time:
