Financing Options

Boiler installation requires a review of heating load, fuel, venting, chimney or sidewall termination, distribution, controls, domestic-hot-water needs, access, and permit requirements. The proposal defines the selected equipment and piping or control changes.

Steam radiation, hydronic baseboard, radiant floors, and domestic-hot-water configurations require different design decisions. Existing piping and venting must be evaluated at the property before equipment is selected. Call for a current appointment window or emergency ETA; timing depends on technician availability, location, traffic, weather, and demand. Project timing is an estimate until the written proposal identifies equipment availability, permits, inspections, access, site conditions, and the authorized scope. Financing is subject to credit approval. Current plans, APRs, terms, and qualification details are maintained on our financing page and may change.

Which Boiler Type Is Right for Your Home?

The right boiler depends on your existing distribution system, fuel availability, and efficiency goals

80–85% AFUE

Advantages

Works with existing steam radiators
No circulator pump needed
Proven technology for older homes

Considerations

–Lower efficiency than hot water
–Slower heat response
–More maintenance required

Price Range: $6,000–$12,000

Homes with existing steam radiators (Garden City Tudors, pre-war colonials)

Hot Water Boiler

Baseboard / radiant floor

85–95%+ AFUE

Even, consistent heat
Quiet operation

Considerations

–Requires baseboard or radiant piping
–Circulator pump maintenance

Price Range: $4,500–$10,000

Most Nassau County homes — Levittown Cape Cods, split-levels, ranches

Condensing Boiler

Baseboard / radiant / fan coil

95–98% AFUE

Advantages

Boiler Sizing Guide

Proper sizing is critical — an oversized boiler wastes fuel, an undersized one can't keep up

Home Size	BTU Output	Typical Home Type
800–1,200 sq ft	40,000–60,000 BTU	Small Cape Cod / Ranch
1,200–1,800 sq ft	60,000–90,000 BTU	Standard Colonial / Split-Level
1,800–2,500 sq ft	90,000–120,000 BTU	Large Colonial / Expanded Cape
2,500–3,500+ sq ft	120,000–175,000 BTU	Large Custom / Multi-Zone

These are estimates. The written proposal identifies the sizing method, design assumptions, selected equipment, included scope, and final price for the home.
