Waterco Hydrostorm ECO-V Variable Speed Pool Pump

At a Glance

The Waterco Hydrostorm ECO-V is a variable speed pool pump with a permanent magnet motor, in a 100 (1hp) and a 150 (1.5hp). The GEN2 ECO-VS 100 is the newer version with RS485 control for pool automation. Run it slow for filtration and it uses a fraction of the power of a single speed pump.

Ideal for

• Pools where the pump runs most of the day and the power bill matters
• Pools next to a bedroom or a neighbour, where a quiet pump counts
• Pools with a cleaner, heater or chlorinator that works better with long, slow circulation
• Automation setups that need to speed control the pump (GEN2 ECO-VS with RS485, or the comm cable versions)

• Comm cable versions (24410090, 24415090): the ECO-V 100 and 150 supplied with Waterco's communications cable for linking the pump to Waterco control equipment. Check with us before ordering if you are matching a particular controller
• Speeds: three presets, ECO, MED and HIGH, each fine tuned by rpm (25 rpm steps on the ECO-V 100 and 150). Waterco says up to 82% energy saving on the 100 and up to 88% on the 150 when run on the ECO setting for most of the day. The GEN2 ECO-VS 100 is quoted at over 80%
• Motor: permanent magnet brushless DC with an IP55 variable speed control panel
• Ports: 50mm quick connect barrel unions, 2.1 litre strainer basket with clear lid
• Seal: 316 stainless steel spring mechanical seal, with a motor protection bracket (61mm gap) that drains seal leaks away from the motor
• Power supply: single phase 220 to 240V, 50Hz
• Flow figures: each flow is the published point at that speed and head, so do not compare it with a single speed pump's flow at a different head. The brochures carry the full table at three heads per speed

Why We Like It

This is the pump to buy if the power bill is the thing that bugs you. The GEN2 ECO-VS is the quietest in the range at 47 dBA on its lowest speed and is the one to pick if your pool automation talks RS485, otherwise the standard ECO-V does the same job for less. The 100 suits most domestic pools; step up to the 150 when you run a bigger pool, a heater or a cleaner that needs more flow on the medium speed. If you only run the pump a few hours a day and want the cheapest option, a single speed pump will do.

Installation

It plumbs in at the equipment pad with the quick connect unions, flooded suction from the pool, so it sits at or below water level. Fit it yourself, or use a pool installer or plumber. Wiring to a fixed supply needs a licensed electrician.

Warranty & Support

3 year warranty on the pump, conditional on the install and use following Waterco's terms, with some wearing parts at 2 years and labour at 1 year. Commercial use is covered for 1 year. DIY installing? Warranty applies when the install follows the supplied install guide. Questions? Call 07 863 8064, real people, Waihi and Kopu stores, Mon to Fri.
