Product Overview

Are you tired of running out of hot water. The Tank Booster is the solution to your problem. If you are unable to get the amount of usable hot water needed out of your plumbing system, installing Tank Booster on your existing water heater can double the amount of usable hot water. The Tank Booster is a thermostatic mixing valve that mixes hot and cold water together to deliver the desired output temperature. After installing, turn the set temperature on your water heater up from 120°F to 140°F. The Tank Booster then mixes cold water back in to reduce the temperature down to a safe 120°F. By storing water at a higher temperature and mixing cold water in to reduce the temperature, you will double the amount of usable hot water delivery from the same size tank. As an added benefit, the Tank Booster protects your entire home from scalding by regulating the output temperature to a 120°F. Even better, by turning up your water heater temperature to 140°F, you can help protect yourself from legionella bacteria growth. The number one cause of legionella bacteria growth is water stored at temperatures of 68°F to 113°F; this bacteria cannot survive at temperatures of 140°F and higher.

Does it cut your utility cost and water usage

Asked by: Anonymous
It could - if you buy a smaller water heater at the same time. Otherwise you will likely use more energy (if you increase the temperature of your water heater), and the same amount of water. But you will be safer - your (hotter) tank will be less likely to grow bacteria, and you will not be scalded. If you don't change the temperature of your tank, there will be no difference, except you will not be scalded.

Does this unit speed up hot water delivery to various faucets?

Asked by: Anonymous
NO. This device mixes hot and cold water together to get a fixed output temp -- it's set at 120F. That means you can boost the water heater temp to 140 or 150 deg, and still have safe (non scalding temp) water temp delivered to your fixtures. This means you have a larger 'thermal reservoir' available, and thus ability to use more hot water in at one time. It wont speed the recovery of the tank. There are a couple simple recirc pumps for aftermarket -- Grundfos markets one, so does Laing (Autocirc). These keep the hot water lines full of hot water, by circulating hot water back through the 'cold' lines. You then have instant hot water available at the fixture. The cold lines heat a bit, but are just lukewarm, as a thermostatic valve shuts the flow when the lines warm to about 90 deg or so. This works well -- I had a system installed in my home, and a 3 or 4 min wait for hot water changed to about 20 seconds. If this is your problem, go look into this. You install it at the furthest fixure, and thus have hot water available in all the lines. It does use a bit of energy, as you're constantly replenishing hot water that's cooled, but you don't waste water (the cold water line empties back into the tank). A timer allows you to limit this usage to times (say morning and evening) when you'd like instant HW available.

How does the Tank booster work?

Is this installed @ tank or each faucet?
Asked by: Anonymous
It is simply a mixing valve. your tank will be set at 140F, the valve will mix cold water for an output of 120F to your house...

Does the tank booster replace the 1-2 gallon tank I currently have installed above my water heater?

Asked by: aMcLean
I would say no. The booster is just a temperature controlled valve. When hot water passes through, it causes the vale to start opening which induces cold water into the mix from the braided hose connection. The idea is that you set your water heater to a higher than normal/comfortable water temp, and then the "booster" actually mixes in cold water as it leaves the heater to bring the temperature back to a comfortable level (120-125degrees or whatever you set it too). If you insulate your water heater, doing this results in the heater running less often to maintain the internal water temp, and when it runs it does so for just a couple minutes more. The net result is a slight savings on gas usage (or electric if that's what you have) and you end up with a significant additional amount of hot water. On my unit with a 30 gallon heater, we'd run out of hot water after 3 showers in the morning (4 adults). After adding the booster, the forth shower might be a bit less warm then I'd like, but it was still warm at least. The booster basically extends the amount of hot water you have available, and that's all it does. This ends up being cheaper than buying a larger water heater, or an on-demand heater that generally costs a lot more.

Water Heater Tank Booster is rated 4.3 out of 5 by 59.
Rated 5 out of 5 by from Great product a fast fix for more HOT WATER! I have been eyeing the Cash Acme tank booster for awhile online and thinking it seemed like a fast inexpensive way to get more hot water without going to a larger hot water tank. To look at it as a plumber its a simple way to accomplish, put the mixing valve right at the tank setting the temperature higher and not sending all your tank water to faucets to be mixed. The install is pretty simple but I doubt the average homeowner will try to do it. Even using Shark Bite fittings, cutting supply lines will make people stay away. I soldered all the pipes added unions and shutoffs on cold and hot side just to make it easy to change my tank when needed, don't have to drain the system down then. Setting the water temperature is simple, but I'm not going to use the supplied thermo-strip. I'm going to add the 3/4" Cash Acme temperature gauge the strip is to hard to see and I doubt the accuracy. I think the best thing about the booster is the hotter the water the more bad things it will kill in your water tank, and our water comes from the river and that is scary enough. Being a plumber the water tank is a place where a lot of corrosion begins and sitting right on top this will get tested. My booster has been on for a week and works great and you can get that extra shower that we could not get before, its worth the price even if you have to change it every time you change your tank.

Rated 3 out of 5 by from Dunno Does it work? Dunno.. gets warm, passes water through it, is odd that the tube connecting the cold side to the valve on the hot side gets warm.. cold water still cold hot is still hot.. haven't tested temps yet but water heater is on 145 and haven't scalded my nippers yet so assuming it works.. the metal flexy pipe connecting the two is a junk pipe and my kit didn't come with the rubber washer and screen like is said it would in box but luckily I had extra from other stuff..

There are several wire screens placed within this unit and the inside diameter is considerably less then 3/4 in., so this may lead to reduced hot water pressure. The unit is well made and does effectively temper the water temperature, but because of the potential maintenance issues with the screens and the reduced water pressure, I have given a three star or average rating.

Conceptually a good idea - I would suspect it results in more energy use to keep the water tank hotter, but they say no? I do notice more fluctuation in the water temperature than before. One thing for sure, they make good money installing these things!
