Hotfill washingmachine Project

[har]

Hello,
There are some instuments to use with a washing machine to fill the washine with warm water. This saves because electrical heating is far more expensieve than with a HR heater.
These instrument are over €200,- so i build one myself.
I use a 3 way motorised valve, which is controlled by a ESP module. As the watertemperure is incoming 60 the resulting temperature inthe machine is about 40. Therefore we use the hotfill only for mashing temps >40.
To realise this the ESP is connected to a switch. When the butten is pressed the valve turns in 'hot' position for 10 minutes.

The use of electrical power is now reduced with approx 80%.

Kind regards,
Har
