Can you elaborate on this?  There are members of this
list who use 
tankless heaters for radiant systems.  I don't
remember them commenting 
on this.  Perhaps they will respond.  Certainly my
tankless heater 
which I use for hot water cycles on and off
frequently.  I wouldn't 
expect more from a system with a slow response time,
such as what you 
get with a radiant heating system.

Thank You Kindly,

The problem with tankless water heaters was not
explained well to me. I think it is because the water
returning from the floor to the heater would be only a
few degrees cooler than the heater out put
temperature. The way the fast cycling was described
was as a "chattering". So, if I am correct, fast is an
understatment.
I ask too, that someone on the list enlighten the rest
of us.
