A tankless (on-demand) water heater heats water only as you use it — so you get endless hot water, a smaller footprint, and lower standby energy loss than a traditional tank. CleanTap sizes and installs tankless systems across eastern Massachusetts with licensed plumbers who get the gas, venting, and water treatment right the first time.
Why Homeowners Switch to Tankless
- Never run out of hot water — ideal for larger families and back-to-back showers
- Space savings — a wall-mounted unit frees up floor space
- Longer lifespan — often 20+ years with proper maintenance
- Efficiency — no reheating a standing tank all day
The Hard-Water Catch
Tankless units are sensitive to scale, and much of Massachusetts — especially well-supplied towns — has hard water. Left untreated, scale shortens the unit’s life and voids some warranties. We routinely pair a tankless install with a water softener and recommend periodic descaling so your system runs at peak for decades.
Proper Sizing Matters
An undersized tankless unit can’t keep up; an oversized one wastes money. We calculate your peak simultaneous demand and confirm your gas or electrical capacity before recommending a model. The same licensed crew also handles your plumbing and HVAC.
FAQ
Will one tankless unit supply my whole house?
Usually yes, when correctly sized. Very large homes may benefit from two units or a point-of-use addition, which we’ll assess on-site.
Do tankless heaters work in cold New England winters?
Yes — we size for incoming water temperature so you get consistent hot water year-round.
