I just installed the HeatGuard Tank Booster, and I am very pleased with the results, though it did not âboostâ my water heaterâs 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 donât 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 1â section of the cold water supply line (leaving 2â clearance on one side and 1â on the other), and 7.5â from the hot water supply line (leaving 1â 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 5 out of 5Â by Sandy 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. .

Rated 5 out of 5Â by Auburn317 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.

Rated 5 out of 5Â by Paul 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.

The perfect temperature for a nice shower. I had just put in a new water heater two weeks ago. Now I don't have to fiddle with the thermostat, and get all the hot water the house needs! Awesome!
