TWIDO - A New French Smart Water Heater that should help lower your Energy Bill

Discovered through EDF Pulse newsletter two weeks ago, this southern France innovation sounds brilliant to me: Be able to have a space saving - flat &  slim - water heater, composed of several small tanks in series, heatable independently and connected to the internet

Intresting quotes from the CEO & Inventor:

"You knows what they're spending on hot water ?"

"The best way to save energy is to not use it at all"

"It's about time to re-invent hot water !"

"This could save a family 20 to 30 EUR per month"



This allows you to get control back on one of the most energy consuming device at home, that had been left as is for decades ....



Slim with 25 cm of depth only


Some options can be mounted onto it, like a toilet seat, a towel dryer, or just decorative lights


Also, as it does not use a sumerged heating element, but an outter heating element - around the container -, they said it could last 20 to 30 years, instead of 10 for a regular one



Follow your hot water energy consumption - Water heater is one of the most energy consuming device at home -


The dedicated App / Website - myTwido.com - allows to get back in control with your hot water use: Heat up only the amount of water you really need instead of the whole tank in a regular unit


Program your tanks heating depending on your real needs throughout the week
Star & Stop heating each tank one by one, you can get hot water faster this way, more economically too



This company's innovative product has been selected by EDF Pulse and is about to win


This is just great, I think, and I am interested in having it installed at home

But wait, there's more ... They have a Solar Twido in the works, that should be able to use your home generated solar surplus to make hot water - like the Energeno Optimmersion in a away -

DIY ESS - AC Charger terminals modification for Water Heater

Before moving all the ESS components to the metal cabinet, I decided to make a last modification to the charger side relay and AC terminals; Instead of having 6 relays for 6 chargers, I removed the 6th one AC wires and left the relay terminal free for my water heater command line (220V, 2A max) that activates the coil of a 220V 20A line that feed the water heater at night during off-peak hours. A signal sent by the utility closes a relay in my utility meter at night and opens it in the morning, and this is how the water heater runs only on low rate electricity. Closing the 6th relay on the same command line, I will be able to switch ON or OFF the water heater as a "6th charger" in a way, meaning, when all the chargers from 1 to 5 will have been switched ON already

If you get my kit, have no water heater - or a gas one, like many in the USA - , use the 6th relay for a charger - like I used too all this time - continuing the AC charger line up to relay 6, the behaviour of the 6th relay has not been changed at all, it is still the 6th charger from teh Arduino point of view !

Then I add to move two chargers on the same AC terminal/ relay twice, like you can see on the photo since I have 7 chargers




I also changed the program so that when the 5th charger comes ON, and the arduino sees that it uses too much power compared to the net power, instead of switching it back OFF, it switches the 1st charger OFF instead, making it more precise (so always install several chargers on the same line towards the end: 4th, 5th)
