Tankless Water Heaters
Excellent Units — With One Hill Country Caveat
Tankless is genuinely good: endless hot water, a much smaller footprint, and a service life roughly double a tank if it is looked after. The efficiency gain is real, and so is never running out mid-shower.
The caveat is our water. A tankless unit heats through a narrow heat exchanger, and limestone-heavy water scales that exchanger far faster than the manufacturer’s general guidance assumes. Descaled annually they last twenty years. Ignored, they lose output and fail well inside warranty terms — so we build the schedule in rather than leaving it to chance.
