Load Calculation
Manual J heat-loss math prevents the classic mistake of oversizing based on the old boiler.

A properly installed condensing boiler quietly delivers even, comfortable warmth for two decades. We size the load, plan the near-boiler piping, and commission the burner so you get every BTU you paid for.
Boilers are unforgiving of shortcuts. We follow the near-boiler piping diagram from the manufacturer, size the primary/secondary loops correctly, and confirm combustion before we leave.

80% AFUE cast-iron, 95%+ AFUE wall-hung, or fully modulating condensing — matched to your goals.
Space and cost savings with a combi boiler that heats water and radiators from one appliance.
Modern near-boiler piping prevents flow issues in multi-zone systems.
PVC sidewall intake and exhaust for condensing units — no chimney required.
Outdoor reset control and Wi-Fi thermostats included to squeeze out every point of efficiency.
Any two of these mean replacement usually costs less than another season of repairs.
Getting these right up front makes for a cleaner install and a longer-lasting system.
A combi saves space and cost but limits simultaneous hot-water use. If you have three showers running at once, a boiler with an indirect tank is better.
Condensing boilers are 95%+ AFUE but need PVC venting and condensate drain. Cast-iron is cheaper up front and simpler to service.
If you're already opening the walls, splitting the house into zones improves comfort and cuts fuel use significantly.
Switching from oil to gas during boiler replacement typically pays back in 3–5 years and eliminates the fuel tank.
