Replacing the boiler in a Westbury ranch, split, or colonial? The decisions that matter are sizing for a long low envelope, venting and condensate routing that survive January, and the fuel question — answered street by street, because the oil pockets here do not follow town lines. Talk it through on the call: the house, the current unit, what is failing.

Why ranches punish rule-of-thumb sizing.
A ranch is the hardest common house to size correctly: big surface area for its square footage, long exterior walls, and heat loss spread thin across a single story. The old boiler was almost certainly sized by rule of thumb — frequently two to three times the building's actual heat loss — and a like-for-like replacement repeats the error. An oversized boiler short-cycles against a ranch's thermal mass: blast, satisfy, shut off, repeat. Fuel wasted, parts worn, comfort uneven — and on oil, an oversized burner soots up faster between services, which Westbury's oil-heavy streets feel directly.
The fix is a real heat-loss calculation, room by room, counting the actual envelope — including finished basements and garage-adjacent utility rooms in splits, which lose heat differently than the main living space. Colonials are more forgiving, with their compact two-story loss, but the principle holds: size to the building, not to the nameplate of the unit being hauled out. Undersized is rare and obvious; oversized is common and expensive, one fuel bill at a time.
Westbury's oil map ignores town boundaries.
Here the fuel decision is genuinely local. National Grid mains serve most streets — but “most” is doing heavy lifting when the oil pockets are block-by-block. One street converted in the eighties; the next never did. So the math has to be computed for your address: is gas at the curb, what does the service line cost, what changes in venting and chimney, what does decommissioning the basement tank run — set against the fuel-price spread over the boiler's life and the value of never scheduling a delivery again.
Staying on oil deserves the same honest arithmetic, not a default. On all-oil blocks with established delivery routes, a modern oil burner with annual service — new burner, clean nozzle, verified combustion — is efficient, dependable heat with zero conversion construction. The tiebreakers people forget: an aging basement tank near end of life belongs in the decision either way, and a condensing gas unit needs a condensate route that survives teen-degree nights — garage-level split installs need that planned, not hoped for. An installer who shows the arithmetic street by street is the one to hire; one who quotes fuel savings from a brochure is not.
Your address decides the paperwork.
Westbury's split personality shows up in permits. A village address permits through the Village of Westbury; a hamlet address — Salisbury and the unincorporated stretches — permits through the town. Same boiler, different counter, different inspection scheduling. This is squarely the installer's job to navigate: a professional answer names the jurisdiction for your street and describes the inspection sequence without hedging.
What the permit process actually governs: venting and flue compliance, condensate disposal routing, gas-line work where applicable, oil-tank decommissioning or removal on conversions, and the final inspection sign-off. Ask whoever you hire to walk it through for your address before you sign — vagueness here predicts vagueness everywhere else.
The sequence, done properly.
The full technical treatment is our national boiler installation guide.
Straight answers before you call.
By heat-loss calculation for the whole envelope, with attention to the long distribution runs. Ranches are commonly oversized from the original install, and oversizing short-cycles, which wastes fuel and leaves far rooms cold anyway. Right-sizing plus distribution that can actually push the far runs is the combination that works.
With your street's facts: whether the mains serve it, what conversion costs, and the condition of your oil tank and burner. Because Westbury's oil pockets do not follow town lines, the answer for your block may differ from the next street over. Get both paths compared on the call with your address in hand.
Short exterior runs, insulated where exposed, pitched to drain, and where possible routed to indoor drains instead of outside walls. On garage-level split installs this is the difference between a quiet January and repeat freeze shutdowns. The install plan should name the routing explicitly.
That is decided with the boiler quote: the 275-gallon basement tank is assessed, and it either stays with a clean bill of health or is removed with its fill and vent lines. Converting to gas means it goes; staying with oil means its condition decides. Get the tank scope in writing either way.
Often yes, with freeze protection designed in: insulated condensate routing, pipe insulation, and sometimes a different unit footprint. Tight, cold utility rooms are a known Westbury layout. Discuss the room on the call; access and temperature both shape the equipment choice.
