Hydronic heating is drawing renewed attention from contractors and homeowners seeking steadier indoor comfort, and Plumbing Supply and More hydronic heating offerings now pair a deep catalog of components with technical selection guidance. Unlike forced-air systems, hydronic heating warms spaces using circulated hot water rather than blown air, which delivers more consistent room temperatures with less noise and no ductwork moving dust through a home.
Hydronic systems work through baseboard units, cast iron radiators or radiant floors, and they pair with gas, oil, electric or wood-fired boilers. Because water carries far more heat than air, these systems can deliver the same capacity with smaller, quieter equipment. The tradeoff is complexity. A hydronic loop contains many components that must be sized to work together, so selecting the correct part matters as much as the installation itself.
To help both trade professionals and do-it-yourself homeowners navigate that complexity, Plumbing Supply and More carries more than 440 products in its hydronic heating category. The selection spans boilers, circulator pumps and circulator parts, expansion tanks, aquastats, flow control valves, hydronic baseboards, kick space heaters, magnetic separators, oil nozzles, oil burner products, radiant heat controls, and steam vents and regulators. Brands carried include Taco, Honeywell, Zilmet, Watts, Hydrolevel, McDonnell & Miller, Weil-McLain and R.W. Beckett.
The company structures its category page as a reference as well as a catalog, with how-to content explaining how each component works, worked sizing examples and common selection mistakes. General industry practice holds that every part supports one of five jobs in the loop: generating heat, circulating water, controlling temperature and water level, managing pressure and trapped air, and delivering heat to the living space.
Many of those parts size off one another. A boiler's BTU output and water content drive circulator and expansion tank sizing, so adding a zone or upsizing a boiler means revisiting both. Circulator sizing relies on flow rate and head loss checked against a pump's published curve, while an expansion tank's precharge should match the system's cold fill pressure to avoid waterlogging and a weeping relief valve.
"Sourcing hydronic heating parts is often where a project succeeds or stalls," said a spokesperson for Plumbing Supply and More. "Customers who understand how components size off each other make better decisions, so the goal is to pair inventory with plain guidance on things like aquastats, low water cutoffs, magnetic separators and oil nozzle ratings."
The spokesperson added that attention to detail protects equipment. "Magnetite sludge builds up in closed loops and is especially hard on modulating condensing boilers, and a mismatched oil nozzle can cause soot or inefficient combustion. Matching the right boiler parts, circulator pumps and expansion tanks to a system is the practical work behind a quiet, efficient install."
Plumbing Supply and More is a family-owned supply house with 75 years in operation, offering wholesale pricing to both trade professionals and homeowners along with a 30-day return policy.
