About This Product

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.

      Answer This Question

      A:  Hi Robert, The Cash Acme Water Heater Tank Booster will not get your water to the fixture faster. You may want to look at installing a recirculation pump. This will help with getting the water to the fixture faster. Unfortunately, we do not make any recirculation pumps that can be paired with a tankless heater. If you have any more questions you can call tech support at 877-700-4242. Kind regards,

          I had the heatguard 0.20 model that only last a 1 1/2. I started getting sputtering water split tempatures and we tried everything clean well filters, clean bathroom faucets nada. So i studied the water system patterns for weeks in the house and my plumber suggested it could be the mixing valve. So i went and bought the new "tank booster" mixing valve problem solved. Now my water pressure has returned and i have all the hot-water i need. If you live on a well system they get rocky with sand, rocks please check this first. pros:very easy setup cons:none so far

              More Hot Water, with a Lower Cost
              This is a great mixing valve and simple to install. But first I like to fill in some back ground, We have a 50 electric duel element heater and if we would to rise our dinner pots and dishes and followed it with our nightly hot bath we always had cold water running before the tub was filled and the water was already set at 135*. After installing the Booster and setting the temp. to 140*, we now rise the pot and all head off for the bath and still have hot water running as the lever hit the overflow. Now that's a boost in my book, with more hot water available for less cost. It may be hard to figure lower cost so let put it this way, before we drained the tank completely, and had to heat a full 50 gals, now we use 30 gals of hot water mixed at the valve installed, so you are only heating the 30 gals.... science... As far as the install goes it's straight forward, turn off power or gas to the water heater and then water to the house, open the valves to relieve pressure at the sinks. SAFTEY FIRST Next, remove the lines on top of the water heater and install the tee to the cold inlet and the mixing valve the hot outlet. Follow by the crossover cold water line from the cold to the mixing valve, three are filter screens, like those for line on washer lines, that need to be in place. The valve is per set for the 120* outlet temp, so all that is left is adjust the water to at lease 140*, turn on the water and bleed air out, check for leaks, before turning back on the power and/or gas. Last step is to check the water temp at the sink, pick one close to the water heater and the farthest, my our double check to check two, temp should by 120 to a top of 125*. Very last detail is to place the sticker that comes with the valve showing the tank is set to 140* and a valve (sink) temp of 120*. My case is by my figuring is a 75 gal capacity now out of a 50 gal electric water heater and I've also added one to my other place with a 40 gal gas water heater with same type of results. In my book, Can't go wrong with this 'Tank Booster".

              Well worth the money !!
              I was in need of replacing my 15 year old water heater and while researching units to buy I saw the ad for this Tank Booster and I liked the reviews and thought what the heck. I bought a new Rheem 40 gallon gas heater and the sharkbite fittings along with the Tank Booster, I call it a blender. I installed it all myself and I'm no plumber, Very good quality and it was great to adjust the water temperature at 125 at the faucet so no more scalding while adjusting the water temperature in the shower or sink. I really recommend this product. For $90, it's well worth it I think. I wouldn't use it in a hard water area without a softener before the tank... Arvada Colorado

              Great solution to a tough problem.
              So your water heater doesn't seem to last long enough; guests, teenagers, large whirlpool tub. And you tried the "turn up the temperature some more". The problem is it makes it difficult to safely control the temperature at each faucet in the house, especially for guests that are unaware. You could replace your water heater with a larger unit. That's expensive. Solution: The mixing valve kit. It includes everything you need for a basic installation to most any type of tank water heater. I have a small electric heater for a single bathroom. I installed this unit and it worked as promised. The instructions, and especially the pictures are very good and very accurate. Follow them carefully. But when you disconnect and reconnect the water supply lines you will notice that the valve takes up about 6 inches of space on the hot side and 3 inches of space on the cold side. So if you do not already have new flex supply lines attached, you may need more parts and make some adjustments to reconnect the supply lines. In my case, I had recently replaced the cold supply that was an older copper flex line with a braided stainless steel supply line. It was flexible enough to handle the 3 inch difference. But on the hot side, I had to bend the 18" copper flex line a lot to make it fit back onto the mixing valve outlet. I will be replacing that supply line soon. It's best to assume you will need to replace your tank supply nipples (preferably with heat trap dielectric nipples), and your supply lines. I even replaced my shutoff valve from a gate valve to a ball valve. Once that was done, I flushed my tank, flushed my lines, and adjusted the temperature. The valve is set for 120 degrees, but I wanted 130. So I set that at 130. I am not sure it will adjust above 130 degrees. I then set my tank at 150 degrees, and left the allen wrench in the valve for future adjustments if needed. One thing I would do differently: I would set my tank to my new temperature (150 degrees) before installation and verify temperature with a temperature probe because water heater dials are not very accurate, and you cannot check the internal temperature once the valve is installed. I decided to clean the strainers to be sure they were clean from the flush. It's important that you depressurize the valve by turning the cold supply off and opening a hot faucet to relieve pressure. I did not open a hot faucet and when I removed the cold supply hose from the mixing valve, the check valve popped out of the valve body. While tech support was easy and fast to reach, I had to figure out how to reassemble the parts myself. (yes it works again.) I'm glad I checked because the screen had debris in it. The thermo-strip was installed but will be useless as I will be insulating the pipes. And it appears only Home Depot will warrant this unit as the manufacturer requires licensed plumber installation only. If your water heater is old, you're better off replacing it with a larger unit. But if you have a newer tank water heater in good condition then you can use this tank booster mixing valve kit to increase your hot water supply. Just be ready to buy new supply lines.

              Great Product, Increases Usable Hot Water
              The TankBooster is an extremly easy to install, average DIYer project that can be done in 15 minutes. After installing the Tankbooster I have noticed a significant increase in usable hot water. The project is simple, turn the water off to the tank and run a faucet to drain the lines. Turn the water heater off remove existing connections and put tee on cold water inlet, Mixing valve on hot water outlet and thread the supplied flex hose from Tee to Mixing valve. Then simply thread back on water heater connectors, I changed my lines out using Sharkbite Water Heater connections and then added a Sharkbite temperature gauge that inserts into a Sharkbite Tee, not necessary to complete the install but I wanted to upgrade the flex hoses and add in a temperature gauge to monitor. Once complete turn water back on, turn Hot Water Heater back on and crank temperature to 140-150 degrees. The mixing valve regulates the temperature down to 120 degrees by mixing in cold water so your tank uses less hot water to reach the same desired 120 degree outlet temperature thereby increasing the usable hot water you can get out of the same tank. Tankbooster prevents scalding by regulating output temperature. By raising the temperature in the tank you prevent legionella bacteria from growing because it cannot survive in temperatures that high. Awesome product and a great way to get more hot water out of your existing tank.

              Good temperature regulation
              I tried the Cash-Acme Heatguard Tank Booster with my tankless gas water heater. With my low flow, the tankless on-demand heater alone tends to scalding temperatures. The Heatguard is a thermo-valve in the hot output and a cross-connection to the cold supply. If the hot water is too hot, it bleeds a little cold water in to temper it. The included fittings are complete for a standard tank heater with 3/4" stubs. If it is plumbed with 3/4" flex to the house, or have PEX with some slack, this goes right in. With rigid plumbing, or with a tankless heater, you will probably need another fitting or two. In preliminary testing it works fine. Instead of a smaller flow of too-hot water, I get a slightly larger flow of just-hot water. In my house, the stock setting gave 110 degrees at the kitchen tap. It can be adjusted higher, they say to trim for 120 degrees. However I find 110 deg to be an excellent limit for hand washing. Time will tell if I need to trim up for optimum bathtub and dishwasher operation. (Most modern dishwashers will hot-up lukewarm water.) The parts appear to be very excellent quality. The fittings are good brass. Water passages are very ample for any house. However the "T" fitting should have a proper hex for good wrench grip, not two tiny flats. (All the other fittings are nicely hexed.) And the packaging is very annoying. It is heatseal bubble pack to keep it all together in the store. But cutting around the plastic was a real chore with good scissors. Then some little bits fell out, but all the big bits are in individual pockets with cardboard glued to the plastic. I started knifing the cardboard but there was danger of stabbing the hose or other parts. As you see in the picture, I made a real mess getting the parts out from under the cardboard without damage or losing any parts. This product should be in a box like a large flush-valve.

              Heatguard tank booster money saver
              The tank booster has saved me money already and I installed it about a month ago. I followed the directions which were very east to understand and got a little excited and ended putting the cold water fitting on upside down. I cant believe I did that Dummy. After looking at the arrow and re-reading the directions I put the fitting on correctly. Set the water at the required temperature of 120 degrees I thought I restarted the hot water heater and after several hours we still had no hot water. Went back to hot water heater and realized that I did not turn the control knob from pilot to run, re-started the Hot Water Tank we had hot water in about 35 minutes. A total of 4 adults taking showers or baths daily and every other day, Dishwasher every evening, Washer running on Friday and Saturday one child taking a bath every other night. I have noticed my gas bill has started to drop and the water consumption has started to drop. Be sure to shut off the cold water coming to the tank, follow the directions, and take your time. As we go forward I will continue to monitor the amount of water used and the gas consumption. I expect to recover the initial investment in less than a years time. Great idea and a sure fired money saver. .

              Plenty of Hot Water and Peace of Mind
              I just installed the HeatGuard Tank Booster, and I am very pleased with the results, though it did not “boost” my water heater’s output because the temperature was already set to 150 degrees. Our water heater had been unable to meet our needs during peak usage times before we increased the temperature. The downside was that the hot water was scalding when not mixed with cold water at the tap. We had never been concerned about burns in the past, but now have a newborn and don’t want to risk injury to him. The HeatGuard enables us to safely keep the water heater temperature very high so that less hot water is needed, mixing cold water in the supply line rather than at each faucet. The major benefits are that the hot water at each tap is no longer a scalding risk, and less hot water is used by appliances that simply draw unmixed hot water such as the washing machine and dishwasher. The parts and components are all of excellent quality and the manufacturer has a great installation video on their website using another of their products, Sharkbite water heater connectors. However the instructions and video were not very helpful for my installation--they seemed simple enough, but I ran into several complications. First, the water lines are cemented to the nipples on the top of my water heater. Second, my gas water heater has an expansion tank mounted on the cold water supply line that is only supported by the copper pipes. Because of these issues, the manufacturer's recommended push-fit flexible connectors were not an option. Instead, I used some of their other push-fit adapters to connect to each end of both the hot and cold water lines. Even if you do not have these particular difficulties with your water heater, it is likely that additional components will be needed to complete the installation unless your water heater is already connected with flexible lines on both the hot and cold side. This is somewhat disappointing considering the price of the kit, but makes sense because every installation is somewhat unique. I recommend a test assembly before cutting the water lines to ensure you have all the right connectors and fittings and know where they go. Also, be aware that both ends of the included flex pipe have rubber seals, but all other connections will require Teflon tape, which is not included. See the attached photo for my completed installation using the referenced push-fit connectors. For this method of installation, remove a 1” section of the cold water supply line (leaving 2” clearance on one side and 1” on the other), and 7.5” from the hot water supply line (leaving 1” clearance on both sides). I found that it was easier to install on the cold water line using a slip-fit connector with built-in fittings on either end rather than to add adapters to both sides of the T piece included in the kit. The end result is a very solid connection on each water line that is able to support the weight of the pressure relief tank. I went ahead and turned the valve temperature adjustment, which comes set at 120 degrees, to the highest setting of 130 degrees. This provides hot water that is 118 degrees at the faucets closest to the water heater. I am comfortable that the burn risk is minimal at that temperature, yet the water is still hot enough to clean with, warm up a bath or take a hot shower. While installation took around an hour and cost a bit more than expected, the peace of mind knowing that there is no longer 140+ degree water flowing to the taps in my house is well worth the price.
