Common Questions
Frequently Asked Questions
Can I replace a steam boiler with a hot-water boiler easily?
Not “easily.” Radiation, piping, and near-boiler design differ. Some buildings stay steam; others convert with significant piping work. Assessment decides.
Do you size from the old boiler’s BTU rating?
No — we survey connected load. Oversized replacements short-cycle and waste fuel.
How long is heat down during a swap?
Many residential swaps target same-day fire-up; complex steam or oil-to-gas can take longer. Temporary heat options discussed up front.
Are permits required in NYC?
Gas work and boiler replacements typically involve filings/authorizations. Exact path depends on fuel and building type — named on proposal.
What maintenance keeps warranty valid?
Annual combustion check, condensate service (condensing units), low-water cutoff testing on steam — intervals on proposal.
Steam vs combi vs conventional HW — how do you choose?
Existing distribution, DHW demand, venting path, and closet space. We recommend against forcing a combi into a large steam building without conversion plan.
