exploreparadise2 Posted December 1, 2011 Report Share Posted December 1, 2011 Although my question pertains to a water heater, the subject is more closely related to electrical. I would like to be able to turn power on and off remotely to an electric water heater in a vacation rental condo that I own. I have WiFi at the condo and I think there should be some kind of device that switches power when accessed online. I have gaps between renters where I would like to save on power consumption and it's too far away for me to switch off in person. I searched online but I didn't find what I was looking for. Do any of you techie types know of such a WiFi receiver/switch that is relatively easy to install in the water heater's power supply?

SNations Posted December 2, 2011 Report Share Posted December 2, 2011 I can't give you a definitive answer, but I have a Honeywell model W8735B Telephone Access Module that works over the phone lines and let's me control my thermostat. That would be a good place to start (or continue) your search. Good luck. It sounds like a fun project. Quote Link to comment Share on other sites More sharing options...
Erby Posted December 2, 2011 Report Share Posted December 2, 2011 http://www.smarthome.com/_/index.aspx http://www.greenwavereality.com/solutions/ Might also just consider installing a tankless. No usage, no hot water. - Quote Link to comment Share on other sites More sharing options...
Bill Kibbel Posted December 2, 2011 Report Share Posted December 2, 2011 Sure. You have to have an interface in the home that receives your computer command and sends an RF signal (and the software on your remote PC). Then you install a control module on the circuit to the water heater. I know of at least one that is for 240V 30-AMP equipment. You can get monitoring modules for water and freezing temps. You can also get control modules to operate lights, any plug-in device, HVAC and even motorized blinds. You can really screw with your tenants. Try "Insteon", which I think is the name of an affordable system. Quote Link to comment Share on other sites More sharing options...
kurt Posted December 2, 2011 Report Share Posted December 2, 2011 The best system is going to be available in about 3 months. It'll blow the rest of the stuff listed here away. I'd say more, but I'm signed to a confidentiality agreement. There'll be an introduction in here in a few months. Quote Link to comment Share on other sites More sharing options...
exploreparadise2 Posted December 2, 2011 Author Report Share Posted December 2, 2011 A tankless heater is not an option. There's no gas service available and the electric service is just 125 amps. Kurt, you've piqued my interest. I'll keep tuned. Quote Link to comment Share on other sites More sharing options...
lbuenzli Posted September 5, 2012 Report Share Posted September 5, 2012 Any luck on finding a control for your electric hot water heater? I am in the same situation. Kurt, what's the breaking news? Quote Link to comment Share on other sites More sharing options...

hausdok Posted September 6, 2012 Report Share Posted September 6, 2012 I missed it too or I would have told you not to turn off the power to a water heater. Once the elements are off and the water cools down it takes about two or three days for the chlorine in the water to become ineffective. At that point, bacteria in the water begins reacting with the anode rod and produces a byproduct - hydrogen sulfide gas. The gas will form a bubble in the top of the tank and when you turn on the hot water after someone moves in again the place will literally smell like someone took a shit on the floor for a couple of hours. Not a good way for renters to be introduced to their new home or the landlord. ONE TEAM - ONE FIGHT!!! Mike Quote Link to comment Share on other sites More sharing options...
charlieb Posted September 6, 2012 Report Share Posted September 6, 2012 It's flammable too. When I first researched the rotten egg smell from the bacteria waste, I found an article on an explosion in the base housing on a military base.

sermolin Posted May 27, 2014 Report Share Posted May 27, 2014 Hi. My old gas water heater in my vacation cabin broke down. My water heating gas bills are low, so I do not want to install an expensive tankless water heater. I do, however, want to be able to control it remotely via internet (I have WiFi in the cabin). To my surprise, I failed to find a gas tank water heater with WiFi enabled remote control. Does anyone know of such a model? Sergey Quote Link to comment Share on other sites More sharing options...
