Boiler & Hydronic Heat Service in Duluth & Twin Ports
Radiant heat, done right.

Cast-iron and mod-con boiler service, radiant & hydronic heat.
Boilers run for decades, and a lot of Twin Ports homes still have the original cast-iron unit in the basement. We service what is already installed and, when it is time, install modern high-efficiency mod-con systems.

Two very different boilers, one honest recommendation.
Cast-Iron Boilers
- Built to last for decades with regular maintenance
- Simple design, fewer electronic parts to fail
- Often already sized correctly for older Twin Ports homes
- Lower up-front repair costs when parts are available
Modulating Condensing (Mod-Con) Boilers
- Higher efficiency, adjusting output to match the actual heat load
- Compact footprint compared to older cast-iron units
- A good fit when a cast-iron boiler is failing beyond repair
- May qualify for financing or available federal credits
Neither option is automatically right. We look at your home, your existing piping, and your budget before we recommend a repair or a replacement.
A boiler that gets checked once a year lasts a lot longer.
Annual maintenance catches scale buildup, failing valves, and combustion issues before they turn into a mid-winter breakdown. If your boiler has not been serviced in the last year, that is the first thing we will check.
