Tankless water heaters for hydronic slab heat

Carp

I have always been warned not to use a tank-less water heater for hydronic heating systems. I am not sure why, but I have heeded the warning. I have a new contractor that wants to do this in a residential slab heat job. What are your thoughts please.



Thank you

tankless water.....

heaters are not designed to do this. Its sort of like using a Moped to travel from Boston to Buffalo on I-90. Will you get there...ya but it will not be a fun ride. It wil certainly not give you the most efficient  fuel use.
