“This black sludge is slowly damaging your heating system.”
Most homeowners never see what’s circulating around their heating system.
Over time sludge buildup can:
❌ reduce efficiency
❌ damage pumps & heat exchangers
❌ create cold spots on radiators
A properly maintained heating system runs more reliably and efficiently.
