Often, yes. Tankless units require a larger gas line for the increased demand. We assess your current line and handle the safe, compliant upgrade as part of our quote.
No. If sized correctly (which KCB guarantees), a tankless unit will not negatively impact your water pressure and often provides better flow stability than an old tank.
We recommend a professional descaling (flushing) every 1-2 years to clear mineral buildup and keep the unit running at peak efficiency. We offer a Maintenance Plan for this service.
