How Does It Work


Pronto On Demand Hot Water Service is a hot water recirculation system that uses an electric recirculating pump installed on your water heater line and a patented thermal valve installed under the kitchen or bathroom sink furthest from the water heater. Pronto on-demand hot water at the tap keeps a constant supply of hot water on demand in your pipes, rather than waiting for freshly heated hot water to travel to your faucet or showerhead. Pronto on-demand hot water at the tap ultimately can save your household thousands of gallons of water per year and decrease your water and sewer bills. Pronto on-demand hot water at the tap annual operating costs are about $2 to $8 a year. 

Our on-demand hot water at the tap recirculation system automatically functions 24/7/365. The system can also be configured with Google, Apple or Alexa wireless control devices, non-WI-FI remote controls, or a simple timer. Our standard Pronto Hot Water at the Tap system uses an electrical, mechanical pump that requires a standard grounded three-prong 120v outlet within 15 feet of the Pronto On Demand Hot Water Service located near the water heater. Even if you don't have an outlet within the required distance, we can often create an integrated and compliant outlet from a nearby outlet or and we may tie into that existing electrical line at no additional cost. Our system does not require electrical outlets at or under your sink. 

How it works: When the water at your faucet cools down, the patented thermal valve opens, allowing the mild pressure from the pump to bring hot water to the patented thermal valve (which keeps the water rapidly ready). No water is lost or wasted because the pumped water is pushed down the cold-water supply line. The patented thermal valve closes when the water temperature reaches around 98F. The process repeats as demanded to ensure rapid warm water at the tap. We can install or recommend power management solutions to turn the system off at night when you are not home or on vacation for an additional cost. Total Pronto on-demand Hot Water at the Tap system installation time is minimal and generally varies between 1.5 and 2.0 hours.

Your Current Plumbing System At Rest

Water in hot water lines cools over time. The farther a faucet is from from your water heater, the more water is wasted while you wait for the water.  Depending upon the distance and the amount of time for the hot water to reach you, gallons of precious water is going down the drain.
