Hot water heated on demand
Tankless systems heat water as it passes through the unit rather than storing a full tank. Compact equipment and potential efficiency benefits can make them worth considering, but output is limited by the unit’s capacity.
Check your home’s connections first
A tankless conversion may need changes to gas supply, electrical service, venting, plumbing, or condensate drainage. These requirements can materially affect the total installed cost.
Size for simultaneous use
Your installer should consider the flow needed by fixtures used at the same time and the required water temperature rise. Discuss maintenance and descaling needs as well as equipment warranty terms.
