I've recently had some plumbing work done. This thread inspired me to ask a few questions of the plumber.
1. I have tank-less hot water- what kind of system would he call it?
Answer- heat coil. On a system like this, he told, your boiler (oil) will come on,occasionally (all four seasons), to keep the coil ready to produce hot water immediately.- It was the occasional (warm weather) running of the boiler that was the real basis of my question.
I get (almost) instant hot water at all faucets (from a well).
2. So, what/is there a difference between what I have and what I've heard is called (tank-less) on demand?
Answer- The heating element in "on demand" only comes in to play when hot water is called for- therefore, it takes longer to get hot water.
I'm not a "handy man", and I understand that certain knowledge and terminology can alter perspectives, but does any of this hold water?
