Tankless Heating Systems ???

[Blackberry Smoke]

After 29 years of faithful service it looks like I'll have to replace our natural gas boiler which heated baseboard hot water radiators. The technician told me instead of simply buying another boiler I should look into a tankless heating system. He said I could retaing the current radiator system. Now I've heard of tankless water heaters but never heard of an entire tankless heating system. Did I misunderstand him or can you know get entire house tankless heating?

Not that I'm aware of . Radiator system is recirculation, need a tank for that . Been years since I worked around any of that stuff

I've had a Polaris system for over 30 years, heating is great and we never run out of hot water. Mine is forced air, not radiators/baseboard, soo.

I've looked into it. Not sure it's any cheaper than my Rheem HE (high efficiency) natural gas hot water tank? Might be worth your while to at least get some estimates?
