Instant Hot Water with this Recirculation Pump with Bypass Valve.

Before we installed this Grundfos Recirculation pump the client was waiting 1 minute and 30 seconds before the water was hot enough to enter her shower. Now with the bypass valve at the nearby sink, drawing hot water to the master bathroom she can enter her shower in less then 10 seconds.

Of course there is always a trade off when installing luxury items. You will use more energy in gas consumption as you are now continually drawing hot water thru your piping system and back to the water heater. I had a bypass system and a tank booster on my home. My energy analysis from my utility company reported that I used 10% more energy then nearby like homes. It equated to around $15 dollars a month. However I shower 2 sometimes 3 times a day as I'm a Plumber and shower the moment I get home.

The other negative to consider is sometimes you will be brushing your teeth with warm water. If you happen to turn on the cold water side of your faucet while the bypass valve is open and drawing hot water to the valve. You will experience the cold water to be Luke warm a few seconds until the bypass valve closes.

Pros. Most obvious pro is the hot water is now available instantly and no more standing outside your shower in your birthday suit waiting for the water to get hot.
Save tons of fresh water as your not sending annually thousands of gallons to the treatment plant or your drainfild. If you pay for your water there will be a money savings of less water used.
