Hydronic and radiant floor heating in Sheboygan County.

Hydronic heating is heating a building with hot water rather than hot air. A boiler heats water, circulators push it through pipe, and emitters — in-floor loops, radiators or baseboard — release that heat into the rooms. There are no ducts and nothing is blown around, which is why hydronic systems are silent, do not stir up dust, and hold a very even temperature.

The boiler is the appliance that heats the water. Hydronic heating is the whole distribution system that carries that water to the rooms — the pipe, the circulators, the zone valves, the manifolds, and the radiators or floor loops at the end of it. People use the two words interchangeably, but they fail in completely different ways, and a boiler in perfect condition can still leave one room cold. Boiler installation, repair and service is here; this page is about everything downstream of it.

Sometimes, and where it fits it is excellent — but it depends entirely on the floor. A basement slab, an addition, a bathroom remodel or a garage are all straightforward. A finished hardwood floor on the main level of a 1950s house generally is not, unless the floor is coming up anyway. There are low-profile systems that add height on top of an existing subfloor, which works if you can live with the transition at the doorways. We will tell you which category your house is in before you get attached to the idea.

Generally no, and often cheaper than the alternatives, because it runs the coolest water of any emitter. Low water temperature is exactly what lets a condensing boiler hit its rated efficiency, and radiant heat also lets most people be comfortable at a slightly lower air temperature than they would need with forced air. The efficiency comes from the pairing, though — in-floor loops fed by a boiler running flat out at 180 degrees waste the advantage.

Hours, not minutes — you are heating a mass of concrete or floor assembly, and it gives that heat back slowly. That is a feature, not a fault: the temperature barely moves once it is there. What it means in practice is that setback thermostats and big overnight temperature drops do not suit radiant floors. Set it and leave it.

In hydronic systems that is almost always air in the loop, a stuck zone valve, a failed circulator, or a system that was never balanced — in roughly that order. Air is the most common by a distance. If the rest of the house is warm, the boiler is making heat and the fault is in getting it to that zone, which is a much smaller and cheaper problem than most people fear when they call us.

Yes, but it will be a separate system, because hot water heat has no ductwork for cooling to share. Ductless mini-splits are the usual answer in hydronic houses — no ducts needed, one head per area, and they heat as well as cool. A conventional ducted air conditioner is possible where there is a sensible route for ducts. Our cooling page covers both options.

Yes — snowmelt loops and heated garage slabs are hydronic systems too, just outdoors and on their own zone. They run much cooler water than the house does, so they need their own mixing assembly and control. The critical point is timing: it is straightforward while the concrete is still a plan and effectively impossible afterwards. Talk to us before the pour.

Yes, and that is most of the ones we see. Sheboygan County has a lot of hot-water heat, some of it fifty years old and added to by four different contractors. We are happy to walk into a boiler room we have never seen, work out what it is doing, and tell you plainly what is worth fixing.
