Hot-water boilers for radiant floor, baseboard and radiator heat, repaired, maintained and replaced by a licensed C-20 HVAC team.
Most homes around Lodi heat with a furnace or a heat pump, so homeowners with a boiler can have a hard time finding someone who works on one. AccuFlow Plumbing, Inc. repairs, maintains and installs residential hot-water (hydronic) boilers that feed radiant floor tubing, baseboard convectors and radiators, along with combination boilers that also make the home’s hot water. Because we’re licensed for both plumbing (C-36) and HVAC (C-20), we handle the water piping, the gas line and venting, and the heating controls, so one company is responsible for the whole system.
A boiler heats water, and a circulator pump moves it through loops of pipe or tubing to the rooms. The water gives up its heat through the floor, baseboards or radiators and comes back to the boiler to be heated again. An expansion tank absorbs the extra volume as the water heats, a pressure relief valve protects the system if pressure climbs too high, and air vents and separators keep air out of the loops. Larger homes are split into zones, each with its own thermostat and a zone valve or pump.
Most residential hot-water systems run at roughly 12 to 15 psi when cold, rising somewhat as they heat, and the relief valve on most home boilers is set at 30 psi. Your boiler’s manual has the exact numbers. A gauge that keeps creeping toward 30, or keeps dropping, tells us where to start looking.
No heat is the most common call. On a modern boiler that usually traces to an igniter, flame sensor, gas valve, pressure switch, circulator or a control board, and the boiler’s error code points the way. Rooms that stay cold while others heat often mean air trapped in a loop, a stuck zone valve or a failing circulator. A relief valve that drips is usually a symptom of high pressure from a waterlogged expansion tank or a fill valve that won’t shut off, not a bad valve. Banging and rumbling, called kettling, comes from scale and sediment on the heat exchanger. High-efficiency condensing boilers add one more: a clogged condensate trap or neutralizer that shuts the boiler down.
A replacement boiler should be sized from a heat-loss calculation for the house, not copied from the old boiler’s label, since many older boilers were oversized and wasted fuel by short cycling. High-efficiency condensing boilers modulate their flame to match demand, vent through plastic pipe and need a condensate drain. A combi boiler heats the home and makes on-demand hot water from one wall-hung unit, which frees up floor space. We check gas line sizing and venting, handle the piping and controls, and pull the permit where one is required.
Planning an addition or remodel? Radiant floor heat under tile is one of the most comfortable ways to heat a bathroom or kitchen, and we can tie it into a new or existing boiler as part of the remodel.
A boiler should be serviced once a year, ideally before the heating season. We inspect the burner and heat exchanger, test the safety controls (high limit, low-water cutoff and relief valve), check the expansion tank charge and system pressure, purge air from the loops, check venting and combustion, and clean the condensate trap on condensing models. It’s the best way to avoid a no-heat call on the first cold night. See HVAC maintenance for the rest of the home’s heating and cooling.
Estimates are free, and you approve a firm price before any work starts. For repairs, the cost mostly comes down to which part failed and whether it’s in stock.
