Little Giant VCMA-20ULST Condensate Removal Pump
The VCMA-20ULST is built to automatically remove condensate produced by boilers, furnaces, air conditioners, and dehumidifiers. It features a vertical-type switch to minimize footprint and a 1/30 HP motor with a fan-cooled design for reliability. The ABS tank and stainless steel motor shaft offer durability, while the thermal overload protection helps guard against overheating in long-running cycles. This model is CSA certified for U.S. and Canadian standards and can handle water temperatures up to 140° F (60° C).
Little Giant VCMA-15ULST Condensate Pump
The VCMA-15ULST provides automatic condensate removal with a compact vertical switch design to minimize space usage. Its 1/50 HP, 1.0 Amp motor operates at 115 Volts with a 60 Hz frequency, and a thermally protected motor ensures safe operation. The pump uses an ABS tank and motor cover with a stainless steel shaft, and it is CSA certified for US/Canada. It is built to withstand condensate temperatures up to 140° F (60° C) for boiler and furnace applications.
Little Giant VCMA-15ULT Condensate Pump With Tubing
This model mirrors the VCMA-15ULST in motor specifications but includes tubing for easier installation and quick setup. It uses a vertical-type switch to save space and offers thermal protection in a robust ABS tank and motor cover with a stainless steel shaft. It is CSA certified for reliable operation in both the U.S. and Canada and is designed to handle boiler condensate temperatures up to 140° F (60° C).
MSELTOS 132 GPH Condensate Pump With Safety Switch
The MSELTOS unit delivers 132 GPH at 1/30 HP with a 20-foot lift, suitable for boilers and larger condensate removal tasks. It features an automatic safety switch and an alarm to indicate overflow risk, helping protect boilers and HVAC systems. The included safety features support automatic shutoff of connected equipment in high-water situations, and a durable design designed for long service life in demanding environments.
Cleartide Condensate HVAC Pump
The Cleartide pump delivers up to 135 GPH with a lift height of 27 feet, designed for low-noise operation at about 25 dB. It operates from 100-240V with a 1/30 HP motor and includes a 5/8 gallon tank, reducing overflow risk in condensate systems. A three-light indicator panel shows power, operation, and malfunction status, and an overflow safety switch protects connected equipment when condensate production exceeds drainage capacity. The unit emphasizes quiet performance and reliability for boiler-to-AC duct systems.
Buying Guide: Key Purchase Considerations For Condensate Pumps
- Flow rate vs. lift height: Ensure the pump can move condensate quickly (GPH) and lift it to the required discharge point (lift height in feet). Boilers often require higher lift than dehumidifiers.
- Power and motor protection: Look for thermally protected motors to prevent burnout during long operation cycles. CSA/UL certifications indicate compliance with safety standards.
- Safety switches and alarms: Automatic safety switches and audible/visual alarms help prevent overflow and protect the boiler, furnace, and surrounding equipment.
- Reservoir and materials: ABS housings with stainless steel shafts offer durability against condensate chemistry and temperature. Reservoir size influences on-off cycling and maintenance needs.
- Plumbing compatibility: Tubing size and included fittings affect installation. Consider pumps with 1/2″ to 1″ inlets/outlets and check for integrated tubing if desired.
- Noise and vibration: For living spaces or quiet environments, choose units described as ultra-quiet or brushless, with design features reducing noise and vibration.
- Footprint and installation: Vertical switch designs save space. If you have limited clearance, multi-models with compact frames are beneficial.
- Compatibility with boiler and HVAC components: Ensure the pump can handle condensate temperatures up to around 140° F (60° C) and is suitable for boiler condensate chemistry.
When selecting a condensate pump for a boiler system, balance flow capacity, lift height, and safety features with the physical constraints of the installation area. Consider future needs, such as potential expansion to larger HVAC equipment or dehumidification loads, to choose a pump with scalable performance. Always follow manufacturer installation guidelines and local codes for electrical and plumbing connections to ensure safe and compliant operation.
