Hydronic system retrofits
hot water radiator
Hot water radiators are a dependable heating method found in many homes, from upright cast units to modern baseboards. When these systems start showing their age, a retrofit is often the smartest way to improve comfort and efficiency without replacing the entire heating setup.
Retrofits typically address the biggest issue older systems face: trapped air and uneven heating. As part of the upgrade, we ensure proper bleeding, balancing, and component updates so every room heats evenly. In multi-level homes, this starts on the top floor and works down to the lowest level for a full system reset.
If your radiators struggle to heat consistently, make noise, or feel outdated, Samson Home Service can retrofit the system to boost performance, cut energy use, and extend its lifespan.
One of the best ways to boost efficiency in a hot-water heating system is to retrofit it for zone control. This upgrade lets different areas of the home heat independently, which is especially useful in large homes where some rooms sit unused or follow a different daily schedule.
Samson Home Service can install automatic radiator valves paired with individual thermostats for each zone. With programmable controls, you can warm specific areas when you need them and scale back the rest to match your routine.
Zoning works best when each area can be separated—either by existing doors or by adding simple partitions—so that warm rooms aren’t constantly losing heat to cooler sections. Any cooler zones should still stay around 50°F to prevent frozen pipes, and heat should never be completely shut off in any part of the home.
If you want to cut energy use and gain better control over your comfort, a radiator zoning retrofit is a smart and efficient upgrade.
hydronic baseboard heaters
Baseboard heating is a reliable and cost-effective option, whether you use it throughout the entire home or to boost warmth in rooms your main system doesn’t fully reach.
Hydronic baseboard heaters use heated water to warm specific rooms or areas in your home. Installed along the bottom of a wall, they pull in cool air from the floor, heat it through a built-in coil, and release gentle, even warmth from the top. Because they run at low exterior temperatures, they can sit flush against walls without causing damage.
This style of heating has been around since the 1940s, evolving from bulky cast-iron radiators into today’s lighter, more efficient designs. In a typical system, water moves from a central boiler to each baseboard unit, then cycles back once it cools. Homes can be divided into zones with individual thermostats, giving you better control over comfort and energy use.
Baseboard heaters can also be customized with various cover styles, blending seamlessly into your space without blocking airflow or heat.
