FAQ
What is the building’s peak hot water demand and usage pattern?
This helps determine whether a traditional tank, tankless, or boiler system is appropriate, and what capacity is needed — especially critical for commercial applications or large households.
Is the existing plumbing and gas/electrical infrastructure compatible with a tankless or boiler system upgrade?
Retrofitting for tankless or boiler systems may require gas line upsizing, electrical panel upgrades, or venting modifications.
What’s the current system’s recovery rate and is it meeting the property’s needs?
This question evaluates whether the existing water heating system is sufficient or if upsizing or a switch in technology is needed (e.g., from tank to tankless or adding a combi-boiler).
Is energy efficiency or upfront cost more important to the client?
Guides the recommendation between high-efficiency condensing boilers or tankless systems vs. more budget-friendly traditional tanks.
Are there zoning, venting, or clearance restrictions that could affect system selection or installation?
Important for both residential and commercial settings — especially for direct-vent systems, high-efficiency boilers, or wall-mounted tankless units.
