<div>My old electrical dux hot water 250l system just died, I am living alone in my house and it cost me about $300-400 a year in power to run it, if I set it to 60degrees.

I when out and got some prices to replace this unit, it will be about $1049 for a new Dux 250L (10yr model), plus install. It’s the same size and specs so it will be a straight and easy swap over. Its funny some places quoted as much as $1700 for a full install on the same model.
