I've had my twin Tec for over a year. I thought it would be difficult to tell I had one but the other day I had my boiler serviced and the well know gas company said how very clean inside it was and how well it was working. I forgot to say that I had a water softener but he did seen genuinely impressed with the system. I assume it has helped . also the bathroom is easier to clean . only down side is the need to buy salt blocks but that not a great problem.
