Egmiku Instant Hot Water Recirculating Kit with Timer — Compatible with Watts 0955805 & Grundfos 595916

Instant hot water at your faucets

Imagine turning on a hot tap and feeling warmth flow within seconds. The Egmiku Instant Hot Water Recirculating Kit is designed to shorten the wait time, helping you skip the slow build of hot water. When the water cools, the upgraded brass sensor valves activate, moving water back toward the heater and resuming steady flow as soon as it reaches a comfortable temperature. A built-in programmable timer lets you tailor the cycle to your daily routine, so the system can run when you most need it without keeping faucets running all day.

What makes it work

The kit uses a compact, cast iron pump head that operates quietly, with a typical sound level around 25 dB. The sensor valves monitor temperature and trigger recirculation only when needed. There’s no need for a separate return line, and the setup integrates with 3/4-inch NPT piping for straightforward connections.

• Instant hot water delivery at most fixtures, reducing wait time from minutes to seconds
• Easy DIY installation with provided supply lines, adapters, and a clear manual
• Low maintenance with durable, long-lasting components and a quiet operation
• Programmable timer for daily or peak-hour operation to match your routine
• Wide compatibility with residential systems, including tankless heaters, storage heaters, solar, and HVAC integrations

What’s included and installation at a glance

The package ships with four supply lines, four adapters, two brass sensor valves (595926), and a user manual. It connects to your existing piping with standard 3/4" NPT fittings and requires no return line or extra plumbing. A 110V power supply keeps things simple and compact.

• 2 brass sensor valves (595926) for automatic start/stop based on water temperature

Energy, efficiency, and real-world use

Quiet operation and a durable build are designed for long-term use in homes or light commercial settings. Because it recirculates water only when needed, it helps reduce the volume of water wasted while waiting for hot water and can contribute to lower energy use during peak hours. In typical installations, the system has the potential to save up to 15,000 gallons of water per year by minimizing waste.

Versatility and compatibility

Designed for compatibility with Watts 0955805 and Grundfos 595916 models, the kit supports a range of configurations—from single-family homes to multi-fixture installations. It works well with tankless heaters, storage tanks, solar heating, and HVAC loops, delivering hot water to all fixtures quickly.
