Replacing a tankless in Salisbury
A tankless that has failed is not automatically a tankless that needs replacing. Heat exchangers commonly carry twelve to fifteen year cover while the rest of the unit carries around five, and the exchanger is the most common terminal failure. We run the serial and check the warranty before quoting you for a new unit, because the part is frequently covered even when the labour is not.
Where a replacement is genuinely warranted, the second unit is usually a much simpler job than the first was: the gas line, the venting and the condensate route already exist and were sized once. In Salisbury the permit goes through Rowan County Building Inspections, for the city as well as the county, and a like-for-like swap in the same location is a considerably lighter permit question than the original conversion was.
Salisbury has one of the most substantial historic housing stocks in North Carolina. The Salisbury Historic District alone counts hundreds of contributing buildings, and it is joined by the North Main Street district, largely built between about 1900 and 1930, plus the Brooklyn-South Square and North Long Street-Park Avenue districts. Late Victorian, Colonial Revival and Craftsman bungalows in quantity. That is a wonderful place to live and a genuinely awkward place to fit a water heater, because almost none of those houses were designed around one.
What Salisbury itself changes
Where the heaters sit
Utility room, closet, crawlspace and occasionally a true basement, which is rarer everywhere else in our area but does turn up in the older Salisbury stock. Access and the route in are the two things that move the price here, and we establish both before the visit rather than after.
The pipe era
The pre-1930 districts are prime territory for galvanised supply still in service, and for a heater that has been replaced several times without anyone touching the pipework around it. Weak flow on hot and cold together is the supply. Weak flow on hot alone is the heater or a heat trap nipple, and those are very different bills.
