Dalrada + ATI of New York · Hot water. Reimagined.
Commercial hot water. A building-wide decision.
Domestic hot water (DHW) means water used for washing, showers and other sanitary uses. It is not limited to single-family homes. For commercial and collective buildings, a heat-pump review starts with the whole hot-water system.

New York project planning
Planning commercial hot water in New York
For a New York building owner or MEP team, the starting point is the property and its operating pattern. Record the site address, building use and existing energy supply before comparing an air-to-water CO₂ plant with the current hot-water system.
- Daily use and the busiest hot-water hour
- Available electrical service and the serving utility
- Plant location, access and distribution temperatures
Begin with demand, not a unit count
Identify daily hot-water use and the short periods when demand is highest. Record delivery temperature, incoming cold-water temperature, operating hours and simultaneous uses. Daily energy and peak flow answer different questions.
Coordinate production, storage and delivery
Heat-pump output depends on operating conditions. Storage can bridge a short peak when usable energy is available; it cannot compensate for a sustained production deficit. Distribution, recirculation and temperature control belong in the assessment.
Make room for the complete installation
Review electrical capacity, structural support, access, airflow, noise constraints, water connections, service space and the existing plant. A rooftop illustration is not an installation design or a guarantee of project suitability.
Questions before you begin
Is a CO₂ heat pump the same as a zero-emissions building?
No. CO₂/R744 identifies the refrigerant. Operational emissions depend on electricity consumption, the electricity emissions factor, other building loads and the system being replaced.
Can the online tools select the final system?
The tools support a preliminary review. Final unit selection, peak-demand analysis, hydraulic design and regulatory requirements need project-specific engineering.
