questionshas anyone ever used the sharkbite tank booster…


I have never used a valve like that. How energy efficient is it to have your water heater set at 140º all the time vs. getting a new tank?

I can see how this would work and probably even work well. My concern is the cost of keeping your water heater at 140º vs 120º would cause a noticable difference in your heating costs. Sometimes the larger, newer tank will help save money in the long run (over the course of about 3-4 years). You could run two water heaters, but that does take up a lot of space.

Some people would rather not replace their water heater unless that absolutely have to, so I could see this as being an easy fix until the current water heater needs replacement.

I just saw the price -- If you ask me, that's kind of steep. What's the current water heater's capacity and remaining life expectancy? Do you have space for a larger water heater?


I don't know what the incremental cost would be to keep the tank at 140 vs 120. I might have the space to have two water heaters, but I don't know whether running them in series is even possible. And wouldn't running two water heaters also increase the running cost? The current water heater is a 40 gallon and I'd like to extend its capacity for better availability of hot water for concurrent and sequential use. I'm not certain of its remaining life expectancy but I believe it's covered by my home warranty.


Your biggest energy savings is keeping your hot water heater set for 120 degrees. If you currently have an electric water heater, check out heat pump water heaters. Great solution if the water heater is in a garage. Much more efficient and there may be rebates available from local, state, or federal governments and/or utility company. If you have a gas water heater, you can't get any more efficient unless you heat and cool with a geothermal system.


Some more thoughts on saving energy.
If your hot water pipes aren't insulated, do it now. The pipe insulation is relatively cheap and available at home stores. Don't get the cheapest they have, get the kind that has a self sealing slit. You want the slit closed to minimize the heat loss. Make good clean 45 degree cuts for corners and use duct (duck) tape to hold the joints together. It's surprising how much hot water you'll save with this. Also, don't forget the last two or three feet on the cold water feed into the hot water heater. Heat is conducted out of the tank on this pipe also. Feel the pipe, it will gradually get cooler as you move away from the heater.
If your hot water heater is in a partially conditioned space like a garage, get an insulating kit at your local home store. This will also save a lot of energy. If the heater is inside your house, there isn't as much loss.


When we remodel, I'm planning on installing a wastewater heat recovery system like 'power pipe' .

It heats incoming cold water with the residual heat from the shower drain. I think it would give you the same result without costing additional money in maintaining the higher temperature in your tank.


I'm going to come out of nowhere with this suggestion, but have you considered a new shower head? We would run out of hot water before the end of two showers when we had an old shower head in our apartment. Replaced it with a 3.5gpm (efficient but powerful) shower head and we can get 3 or 4 showers in before running out of hot water.


anti-scald fixtures do the same thing, this is not much more than a gimmick, if you don't have any young ones in your house go ahead and turn up your water heater and you can adjust the mix yourself while in the shower. you can th. see if the increase I'm your bill is acceptable. my heater is at 135, but i dont have any kid that can get hurt by the increased temps. Just remember you may be able to take a longer shower but your dish washer and clothes washer will also see the increase and you will not save anything there without a device like this.


I like @omnichad: 's response. Have you considered a tankless hot water heater? I am not sure you can do this but could you use the tankless as a booster? (My 10 second google search did not find any answers.)


Sirlouie, I'm interested in knowing if you or anyone reading this has purchased the Hot Water Heater Tank Booster by SharkBite or HeatGuard? If so can you give a review on the product. I've been unable to find any reviews on the product.


@bhamjonathan: I ended up just sticking with the water heater I had and I've been ok. Sorry I can't be more help.


The tank booster works GREAT! We had a 4-5 year old gas water heater(cheapest model available at the time). Always ran out of hot water on second shower or while doing laundry/dishes and shower, I even had the tank water temperature hotter than recommended. After installing the tank booster and setting it up for 125 deg. hot water at the nearest sink we can take 2 long showers and run the dishwasher or laundry without running out of hot water!!! Installation was 1.5 hours, i purchased longer fittings to connect the tank booster to the water heater (easier to install) and used the shark bite hoses to connect to the water pipes! Great products!!!
