30-liter water heaters for sale

I have 4 Saudi ceramic water heaters for sale, 30 liters each. They come with invoices; I've had them for 14 months, less than two years. There is a smell; I called the technician and he said the heating elements inside are burnt and need replacement. The buyer takes them as they are. I guarantee they work, but there is a smell coming from the water, so they require cleaning and maintenance. May God bless whoever buys these four. Price is negotiable.
