What Goes Into a Boiler Replacement

A full replacement is a planned project, not a rushed swap. Here is what the work covers from the first visit to the final test, so you know what your price includes.

• Heat loss calculation: We count radiators, measure rooms and check windows and insulation, so the new boiler matches what your house actually needs today and not what it needed in 1950.
• Options and written price: You see choices at different price points, with clear numbers on what each one includes, before you agree to anything or sign a contract.
• Removal of the old boiler: We drain the system and haul out the old unit, a heavy job in tight basements that we handle with care for your floors and walls.
• New boiler and piping: The new unit is set, piped to your existing loops and fitted with a fill valve, expansion tank and pressure relief valve in the right places.
• Venting or liner: Cast iron units can use the existing chimney with a liner, while high efficiency boilers vent through PVC or stainless pipe to the outside.
• Controls, permit and startup: Outdoor reset controls, the township permit, the inspection and a combustion test complete the job and prove the system runs safely.

Cast Iron vs High Efficiency Mod Con Boilers

Cast iron costs less and is simple to service. Modulating condensing boilers burn less gas but need good piping and venting. A cast iron boiler vs modulating boiler choice depends on your radiators, your budget and the layout of your basement.

Where Cast Iron Fits

• Lower upfront price than most high efficiency units, which helps when the budget is tight
• Simple controls that many techs know well, so future service is straightforward
• Works with existing chimneys when a stainless liner is added for safe venting
• A good match for older radiator systems that were designed for high water temperatures
• Long life when the water is kept clean and the system is serviced each year

Where Mod Con Fits

• Burns less gas by lowering its output as the weather warms up outside
• Needs PVC or stainless venting, often out a side wall, which takes planning on tight lots
• Works best with outdoor reset controls and careful piping to stay in its efficient range
• Can pair with an indirect water heater, giving plenty of hot water without a separate tank burner
• Costs more up front but often saves fuel year after year in a home that is well sealed
