Same day. We’re based in Hudson and Bolton is a quick drive. We keep 30 units in our warehouse — gas, electric, and power-vent. Call (978) 562-3736. Bolton well water punishes water heaters, and when one goes, it goes fast.

Bolton’s well water carries heavy iron and manganese. The minerals settle on the tank bottom, forming a sediment layer that acts like insulation between the burner and the water. The steel overheats, the glass lining cracks, and the tank rusts through from the inside. The same heater that lasts twelve years on municipal water might make it eight or nine in Bolton without regular flushing.

Every six months. Attach a garden hose to the drain valve at the bottom, run it outside or to a floor drain, and let it flow until the water runs clear. With Bolton’s iron levels, you’ll see rusty water for the first few gallons. If the drain valve is clogged — common with the cheap plastic valves most manufacturers install — don’t force it. We can swap it for a brass valve that won’t clog.

A standard gas water heater with a powered anode rod. The powered rod doesn’t get eaten by iron and manganese the way a standard magnesium rod does. Electric heaters work but the lower element sits in the sediment and burns out faster. Power-vent units are fine — the blower motor doesn’t care about water chemistry. The maintenance matters more than the fuel type.

Almost always the thermocouple — the sensor that tells the gas valve the pilot is lit. Bolton basements are often damp, and moisture accelerates corrosion on the thermocouple connections. We can swap it in about 30 minutes. If the gas valve itself is failing or the burner assembly is rusted, replacement is the better call.

Probably. Sulfur-reducing bacteria thrive in the warm, still water inside a water heater tank, especially on well water. The bacteria react with the magnesium anode rod and produce hydrogen sulfide gas — the rotten egg smell. Swapping the magnesium anode rod for an aluminum or powered rod usually eliminates it. We can do it in one visit.

A standard 40-gallon gas unit runs $1,500 to $2,200 installed. A 50-gallon power-vent runs $1,800 to $2,800. Electric runs $1,200 to $1,800. Bolton’s long pipe runs sometimes mean we need to add an expansion tank if one isn’t already in place — that adds $150 to $300. We quote everything before we start.

Often yes, but we need to check the flue size first. A 40-gallon gas heater uses a 3-inch flue. A 50-gallon usually needs a 4-inch flue. If your chimney flue is the smaller size, we can use a power-vent unit that vents through a sidewall with PVC — no chimney needed. We’ll measure and tell you what fits.

Yes. Every Bolton address, including homes set far back from the road. We carry the parts and units we’re most likely to need, so we don’t burn time on supply house runs. Same-day service applies to the whole town.
