Waykar CHWA150PB 150-pint ENERGY STAR dehumidifier with pump review

CHWA150PB is the only pump-equipped option in the Waykar CHWA-B selector. It combines the family’s 150-pint maximum rating and auto-swing outlet with a fitted pump that discharges after the water tank reaches its maximum level. The exact manual supports uphill drainage but does not state a maximum vertical lift or total hose length, so the pump is a real feature—but not a quantified promise for every raised drain.

I reviewed the exact Waykar CHWA-B page and pump variant, the manual that names CHWA150PB as the pump model, and its EPA ENERGY STAR record. Those references establish configuration and ratings, not performance in a home.

Waykar’s CHWA-B selector uses one family image for the pump and non-pump sizes. Check the selected model code and plan the hose route separately.

The pump changes the water route, not the capacity

EPA rates the CHWA150PB at 49.52 pints/day under Appendix X1, with a 2.01 L/kWh integrated energy factor and 499 kWh/year. The manual rounds its 65°F/60% RH capacity to 49.5 pints/day, lists 75.4 at 80°F/60% RH and 116.8 at 86°F/80% RH, then reaches the 150-pint label only at 95°F/90% RH. Its EPA record confirms ENERGY STAR certification, says it is not Most Efficient, and lists Connected Capable: No. The matching CHWA150B has the same standardized capacity and efficiency record; the PB suffix adds a pump path, not more moisture removal.

Waykar estimates coverage up to 7,500 square feet, but that is not a guaranteed operating area. A damp crawlspace with outside air leaks can behave differently from a closed room at the same floor size. The manual’s minimum operating area is 43 square feet, its recommended clearance is 18 inches, and its operating range is 41°F–95°F. Do not place the unit where the inlet or outlet is blocked.

What the pump instructions confirm

The manual identifies CHWA150PB as the only pump model in this group and shows an included pump drain hose with 0.17-inch inner and 0.25-inch outer diameter. The manual says the pump begins when the tank reaches its maximum level and stops after water is drained to the minimum level. The tank therefore remains part of this operating plan; this is not documented as bucketless operation. The manual also says the pump needs to be reactivated manually after a power interruption even though the dehumidifier itself resumes its previous settings.

There is an important limit to what the sources say: they describe uphill or long-distance drainage but do not publish a maximum rise, total pump-hose length, or a combined horizontal-and-vertical route. Do not transfer a lift figure from another Waykar model. If your sink is above the appliance or the hose must travel a measured distance, confirm those dimensions with the manufacturer before relying on the pump. The finder can recognize the pump route, but a numerical lift or hose-reach requirement remains unknown for this exact model.

For lower outlets, the same manual describes the supplied 3.3-foot gravity hose and a smooth downward run, with the outlet at least 3.94 inches below the drain port. You can also collect water in the 2.38-gallon tank. That gives three possible ways to handle condensate, but each needs its own setup: tank for manual emptying, gravity for a lower nearby outlet, pump for a confirmed raised or longer route.

Auto-swing, controls, and maintenance

The top outlet sweeps automatically when the Auto Swing button is enabled; the manual says not to push the louvers by hand. It also provides three fan speeds, a 24-hour timer, auto-defrost, child lock, and a 30%–80% target-humidity range in five-percent steps. There is a removable rear filter for regular cleaning. These controls are the same kind of everyday functions offered on the non-pump B models, while the separate pump button is unique to CHWA150PB.

The 150-pint maximum and auto-swing controls do not imply Wi-Fi or app control. The EPA Connected Capable field is No, and the exact manual and page do not document an app. Likewise, the sources provide no numeric sound measurement or cabinet dimensions. If app control, noise, exact height, or a precise pump rise is essential, verify it rather than using a sibling’s specification.

Who should consider CHWA150PB?

This variant is worth comparing when you want a roughly 50-pint/day standardized rating and need a pump-equipped product rather than a tank-only or gravity-only configuration. It is the only pump model among CHWA80B, CHWA120B, CHWA150B and CHWA150PB; choosing the 80- or 120-pint selector does not add the pump. Compared with CHWA150B, the two have the same rating and tank volume, so the useful difference is drainage. Compared with CHWA120B, it adds capacity and a larger 2.38-gallon tank, but still needs a route-specific lift check.

Do not buy it solely because “pump” appears in the variant name if a guaranteed lift height is essential. The exact manual confirms upward pumping but gives no number; a higher sink, window, or long run may exceed the unknown limit. Use the tank or lower gravity hose if those fit your room. Confirm that the offered SKU says CHWA150PB, plan to reconnect the pump after power loss, and keep the tank accessible for cleaning and emptying when its sensor reports full.
