Boilers & Hydronic Heating
The classic heating system of the North Shore—done right.
Many of the North Shore's finest older homes were built with hydronic heating. We service, repair, and upgrade boilers. And we're honest about when a geothermal upgrade makes more sense.
Modern condensing boilers
High-efficiency boilers that capture more heat from every cubic foot of gas.
A well-maintained boiler can last 30+ years. Modern condensing boilers are substantially more efficient than older units — and they work with your existing hydronic distribution.
- 90–95% efficiency ratings vs. 80–85% for older boilers
- Condensing technology captures latent heat in exhaust gas
- Modulating burners match output to heating demand
- Quiet, reliable operation — no on/off cycling
- Compatible with existing radiators, baseboard, and radiant floors
- Combination units can provide domestic hot water from a single system
Is a condensing boiler right for your home?
The best candidates for these high-efficiency systems are homes with existing hydronic piping in good condition. During an in-home visit, we'll check your specific venting, piping, and chimney details to provide clear guidance. We’ll walk you through whether to upgrade to a condensing model now or begin planning for a future transition to heat pumps or geothermal.
Hydronic distribution
From radiant floors to cast-iron radiators.
Radiant floor heating
Baseboard & cast-iron radiators
Hot water circulates through tubing beneath your floor, delivering warmth from the ground up. It's the most comfortable way to heat a home — even, quiet, and invisible. Works beautifully in bathrooms, kitchens, basements, and whole-home installations.
Classic hydronic distribution through baseboard heaters or cast-iron radiators. Still effective, still popular — and cast-iron radiators in particular are design elements in historic homes.
- Even, consistent heating throughout every room
- No cold spots, no drafts, no visible hardware
- New construction or retrofit installation
- Zone-by-zone, room-by-room control
- Reliable, straightforward maintenance
- Works with any boiler system
Our boiler services
Emergency repair, maintenance, and replacement.
Emergency repair
Boiler won't start? System is leaking? We respond quickly to get your heat back on. We service all boiler brands and models, and we keep parts on hand for common failures.
Preventative maintenance
A seasonal tune-up keeps your boiler running efficiently and reliably. We inspect, clean, adjust, and test. Most boiler problems can be caught and prevented before they become emergencies.
Boiler replacement
We'll specify a modern, efficient replacement that works with your existing distribution system—and we'll be honest if a geothermal upgrade would be a smarter long-term investment.
Repair or replace?
Repair if…
Replace if…
Your boiler is under 15 years old, the repair cost is under 50% of replacement cost, and the system is otherwise sound. A repair can often buy you 5 more reliable years.
Your boiler is over 20 years old, multiple components have failed, efficiency has dropped noticeably, or repair costs are approaching replacement cost. We'll give you honest numbers either way.
Your boiler is under 15 years old, the repair cost is under 50% of replacement cost, and the system is otherwise sound. A repair can often buy you 5 more reliable years.
A path to electrification
Love your radiant system but want to go electric? Geothermal is the answer.
If you love your boiler's warmth but want to move away from gas, a geothermal heat pump can drive your existing hydronic distribution—keeping your radiant floors or radiators and simply replacing the combustion appliance with a highly efficient electric heat pump. This is a common upgrade path for North Shore homeowners who want to modernize gradually.
