Diversitech FP-22 Condensate Pump for Furnace & Boilers
The FP-22 is built for acidic and high-temperature condensate, handling water up to 190°F. This makes it suitable for steam boiler installations where condensate can be hotter than typical condensate from air conditioners. It offers a 22-foot lift and steam-resistant electronics, ensuring reliable operation in demanding HVAC applications. Vibration-dampening feet and metal hang tabs improve stability and reduce noise during operation.
Best for: installations where condensate is hot or acidic and a robust mounting solution is needed. Choose this if you expect elevated condensate temperatures and want durable, vibration-resistant performance. Caution: ensure compatible electrical wiring and space for secure mounting in tight boiler rooms.
Beckett CB501ULHTS Large Condensate Pump
This Beckett unit offers a 50-foot maximum lift and a high-temperature rating up to 212°F (100°C). It runs on 115V, 60Hz and 360 watts, making it a solid choice for basement utility rooms or larger boiler rooms where long vertical discharge paths are necessary. Best for: facilities needing substantial lift capability and reliable performance in higher-temperature condensate conditions. Limitation: higher lift capacity may come with larger footprint or installation considerations.
Little Giant HT-VCL-60-P Condensate Pump
The HT-VCL-60-P is a 1/3 HP, 115-volt pump designed for high-temperature condensate removal with a maximum temperature of 212°F. It includes a built-in float switch for automatic operation and an external test lever to verify function without filling the tank. It also offers a safety switch wiring option to shut down connected appliances or trigger an audible alarm. Best for: demanding commercial plenum or industrial installations where reliability and safety interlocks are essential. Caution: ensure compatibility with the pump’s electrical and control wiring in your facility.
Little Giant HT-VCL-30-P 208-230V Condensate Pump
This model mirrors the 60-P’s high-temperature capability but operates at 208-230V. It provides 32-foot shutoff and a built-in float switch for automatic operation. A safety switch wiring option allows integration with other safety systems. Best for: projects requiring 208-230V power with solid high-temperature performance. Limitation: slightly lower lift than the 60-P model, so plan discharge routing accordingly.
Little Giant HT-VCL-30-P 115V Condensate Pump
This 115-volt version also handles high-temperature condensate up to 212°F and includes the automatic float switch and external test lever. It supports safety wiring to shut down equipment or activate an alarm, with an optional alarm not included in the package. Best for: 115V installations in commercial spaces requiring reliable high-temperature operation. Limitation: ensure electrical supply matches the 115V model before purchasing.
Asurity by Diversitech ULTRACP-22T
The ULTRACP-22T is a compact HVAC condensate pump offering 22 feet of vertical lift and 160°F condensate handling. It ships with 20 feet of 3/8″ discharge tubing and is designed for automatic condensate removal, reducing manual drainage. Best for: tight spaces or basements where tubing length and compact form factor matter. Caution: tubing length and routing must be planned to avoid air locks or backflow.
Buying Guide
What matters most when choosing a steam boiler condensate pump?
- Temperature tolerance: If condensate can reach high temperatures, choose models rated for at least 160–212°F (71–100°C).
- Lift height: Measure the vertical distance from the condensate source to the drain or discharge point. Select a pump with a lift greater than that measurement to avoid drainage issues.
- Power and voltage: Match the pump’s voltage with your facility’s electrical supply (115V vs 208-230V). Consider automatic operation features for hands-off control.
- Automatic operation: A built-in float switch helps prevent overflows by starting or stopping the pump automatically as condensate accumulates.
- Tubing and connections: Some units include discharge tubing; confirm compatibility with your drainage line and check for included adapters or tubing lengths.
- Size and installation space: In tight boiler rooms, compact units with mounting options and vibration reduction are advantageous.
- Safety features: Look for safety wiring options to shut down linked equipment if the pump fails or if a fault is detected.
FAQ
- What is the typical use for a condensate pump in steam boiler systems?
Used to remove condensate produced by boilers and steam systems, especially when drainage is not gravity-fed or located above the discharge point. - Do these pumps handle hot condensate from steam boilers?
Yes, several models are rated for high-temperature condensate up to 212°F (100°C). Always verify the specific model’s temperature rating. - Is automatic operation important for condensate pumps?
Yes. Built-in float switches automatically start and stop the pump, reducing overflow risk and manual maintenance. - Which lift height should I choose?
Select a lift higher than the vertical distance to the drain. A higher lift provides more installation flexibility but may be physically larger. - Are there safety considerations when wiring these pumps?
Some models offer safety wiring options to shut down connected equipment if the pump trips or fails, which is important for system protection. - Can I use a compact pump in a basement utility room?
Yes, compact models with appropriate lift and tubing options are designed for tight spaces while still handling high-temperature condensate.
