The Tank Booster is a cost-effective solution for increasing usable hot water capacity on an existing water heater or a new high-efficiency water heater. This product is a mixing valve that combines hot and cold water to ensure that water is delivered at a constant, but safe temperature to all outlet fixtures. This valve also reduces the risk of Legionella bacteria growth within your water heater by increasing the water storage temperature to a germ-killing 140°F (60°C). The valve features internal safety shut-off features in the event of either a cold or hot water failure.

Rated 5 out of 5 by from 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

Rated 5 out of 5 by from Excellent product! This product does exactly what it advertised. Easy install, quality components, tons of hot water. I replaced a worn out tank extender with this product. The steel braided flex hose made re plumbing super easy. Some of the reviews of this product question the purpose of mixing cold water at the tank vice mixing at the fixture. I live in Hawaii and I use two roof mounted solar panels to heat my water during the day. My tank temperatures routinely exceed 155 degrees. These temperatures are dangerous for my small children. This product allows me to store hot water that exceeds federal safety standards AND safeguard my children from scalding.

Rated 5 out of 5 by from FANTASTIC!!!!!!! I could not be happier with my purchase. The tank booster was an absolute breeze to install(I used a sharkbite water heater hose and ball valve for an even simpler installation). It took me approximately 15 minutes from start to finish. I have a 40 gallon water heater that the wife and kids were running empty every morning. Since installing the tank booster they can all shower back to back and I still have a long hot shower waiting for me when they are done. Much cheaper, faster, and easier than buying a larger water heater.

It does a good job of regulating the outflow temperature to the household's hot water pipe. It extends the water in the tank and keeps usage of hot water out of the tank from becoming inconsistent in temperature. I found that my showers temperature change over time is not an issue as it was with a tank that didn't have this regulator. It should be an energy saving device too, as it keeps the hot water tank from getting unnecessary water pull through it, thus saving money on reheating costs of the hot water. I totally recommend this device as a money-saver.

Rated 5 out of 5 by from working great Very easy to install if you putting in a new HWH at the same time . If you are adding it to an existing HWH you are going to have to shorten both inlet and outlet pipes to accommodate the additional hardware. It is working very well, both by regulating the output temperature to 120 degrees and lengthening the length of time there is hot water available for the household. We have not run out yet after two weeks of use. WARNING! Before you adjust the output temperature be sure you have the hot water running at a faucet or you will damage the valve. This is in the instructions but some men just won't read through the entire set of directions before messing with a gadget.

Rated 5 out of 5 by from Helped Solve Loss of Hot Water My Bradford White electric water heater was around 7-1/2 years old, when the duration of hot water was only a few minutes before running cold. I took 3 steps: 1) replaced the heating coils, 2) replaced the anode rod, and 3) added the Cash Acme Water Heater Tank Booster Pro. The two heating elements and anode rod cost around $70 with shipping. I thought about making the above changes myself, but I decided to have a plumber do the job, in addition to replacing the plastic 1/4-turn valves with brass. The plumber’s cost was $597. The results: no more hot water loss and the water heater is now better than new. I am a very happy camper.

Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from Perfect for households of 4+ The tank booster was pretty easy to install. Hardest part was calibrating the water temp at the end. I wouldn't say it increases your hot water out put by 50% but it does help take your hot water further than with out it. It is also nice to know that with the blend of hot and cold that my children will not get scolded if they turn the hot all the way up.

can this be used in a large plant sanitation cleaning?

Asked by: adam s
Good morning, You should use our products according to their specifications and designed purpose. Tank Boosters are meant to go in potable water system and connect directly to Water Heaters. Anything other than this, we would recommend not using our product.

I am having a new water heater installed and adding a Shark Bite tank booster at the same time. It says the hot water should be running when the booster is adjusted. Does the water have to be hot or just the hot water valve on my faucet open?

Asked by: David A
Hello, The tank booster should have hot water running through it at the time of adjustment. Thank you

I would like to buy the water heater booster but wanted to know if it will be compatible with any brand or model. The one I have is a Rheem 2003 model 41VR50N. Also would like to know price. My local Home Depot which is a Large one does not have it. 

Asked by: Serch
Good morning, We do not sell direct, so we are unable to provide a cost. You can use this link ( http://www.sharkbite.com/find-a-store/?type=a_location&zip=&distance=5&ltype=wholesale) to locate a local vendor who can provide a quote. If they do not have it on their shelves, you can work with them to special order it. As long as your system meets the required specifications (link to spec sheet: http://www.cashacme.com/resources/tank-booster-pro-spec-sheet/), you can use our product with any water heater.

Just installed hot water heater tank booster and I have no hot water pressure.

Asked by: Kforeman
Hello, I can not think of a reason why your water pressure would have been affected. Can you forward pictures of the installation to david.crawford@rwc.com so I can attempt to troubleshoot? Thank you
