I have a OWB and would like to have the water temp displayed in my house, preferably digital. Any Ideas, I dont want to spend a ton of $$$. The only thing I come up with would be an automotive style gauge with a electric sending unit.
I got one from my Central Boiler dealer can't remember price but it was under 100 dollars. Probe goes on pipe for water heater and digital display and also believe you can monitor multiple temperatures.
Buy one of the ones that are intended for use with an outdoor smoker (BBQ) pit.
Dual channel remote wireless (to the receiver) units are available on ebay for under $50.
Maverick ET-73 if I remember.
You can surface mount the probes to the pipe wall with some heat transfer compound to ensure good heat transfer.
