Can I use Noritz heaters for heating and domestic hot water?

Yes, you can use the Noritz tankless water heaters for domestic hot water in conjunction with a heating system but not solely for a heating system (closed-loop1 system).

See installation manual located at http://support.noritz.com/technical-literature.php
