15 best booster for water heaters

A booster for water heaters, also known as a water heater booster, is an accessory device designed to enhance the performance and efficiency of a standard water heater. It is typically used to increase the hot water output of the water heater, making it particularly useful in households or commercial settings where there is a high demand for hot water.

Here are some key points about water heater boosters:

  1. Purpose: Water heater boosters are used to increase the temperature of the hot water produced by a water heater.They are particularly beneficial in situations where the existing water heater is unable to provide sufficient hot water to meet the needs of the household or business.

  2. Installation: These devices are typically installed in-line with the hot water outlet of the water heater. They are connected to the existing plumbing system and are usually electrically powered.

  3. Temperature Adjustment: Water heater boosters often come with temperature adjustment settings, allowing users to customize the desired hot water temperature. This ensures that the hot water supplied is at the desired temperature.

  4. Energy Efficiency: By increasing the temperature of the hot water at the source, water heater boosters can help reduce the need for mixing hot and cold water at faucets and showers. This can lead to energy savings since less cold water needs to be added to achieve the desired temperature.

  5. Compatibility: It's important to ensure that the water heater booster is compatible with your specific water heater model and plumbing system. Proper installation by a qualified professional is recommended to avoid any issues.

  6. Size and Capacity: Water heater boosters come in various sizes and capacities to suit different needs. It's important to select a booster that can meet the hot water demand of your household or business.

  7. Maintenance: Like any mechanical device, water heater boosters may require periodic maintenance to ensure they continue to operate efficiently. This may include cleaning the unit and checking for any potential issues.

  8. Cost: The cost of a water heater booster can vary depending on its capacity, features, and brand. It's important to consider the upfront cost along with potential energy savings when making a purchasing decision.

In summary, a water heater booster is a device that can be added to a standard water heater to increase its hot water output and improve overall efficiency. It is a valuable addition in situations where there is a high demand for hot water, such as in large households or commercial settings. Proper installation and maintenance are essential to ensure the booster functions effectively.

The MegaBoost is designed to be installed with any domestic hot water tank, new or existing, gas or electric. It will provide more hot water for longer showers and shorten the tank’s recovery time. It achieves its boosting effect at 100% efficiency. MegaBoost installation is flexible as it is designed to be installed on either the tank’s cold water inlet or on the hot water outlet. A 30-gallon tank with MegaBoost installed on the hot water outlet will provide 54% more hot water than the tank will without MegaBoost. If MegaBoost is installed on the cold water inlet it will provide 71% more hot water. In addition, the recovery rate for the tank is also reduced, significantly reducing the wait time for the tank to recharge. MegaBoost may allow using a smaller tank than a larger one which will save space and save money by preventing the increased standby losses of a larger tank.

  • More hot water for more Showers or longer Showers
  • Saves space by making a small tank perform like a large tank
  • Fast & accurate hot water temperature adjustment for convenience and comfort

User questions & answers

Question: Will this keep a constant output temperature (120) if my hot water heater varies from 120 to 140 to take advantage of time of use electric rates
Answer: Any insulation is good for saving on your water heating bill. This is a relatively thin layer so it might be easier to install in a crawl space. Be extra careful not to rip the foil coating. It is thin and tears easily.
Question: If I need a longer hose, can you just use any appliance hose with 3/4" fittings or is there something special about the hose proided
Answer: Going by 3" thickness, the R value should be 10 - the same as the SP57 model.
Question: What is the length of the flexible hose
Answer: I cannot recall exactly how the one I ordered was packaged, and my hot water heater is right at 5’ and it covered it well. You will just need to open it (it could be folded) and if it is smaller than the stated dimensions, return it.
Question: Will this help boost production on a tankless water heater
Answer: The "blanket" is merely a thin section of insulation with mylar covering on one side. Cutting it is easy with scissors and will do no harm. The mylar is very thin and you must be careful not to puncture it. You may want to buy a roll of tape. The pieces that come with it don't go too far.

User questions & answers

Question: is this
Answer: Hi Angela! Yes, this has a ¾” female hose with ¾” standard water heater connections.
Question: How fast does water take to get hot? I usually have to wait for my shower to get hot. My bathroom on the other side of the house
Answer: The time that the water takes to get hot is dependent upon how far it has to travel from water heater to shower. You may have a shower valve problem if it takes more time to reach the shower than the bathroom sink. To test this, first thing in the morning run only hot water to your sink and time it from the moment you turn on the hot water till it starts to warm up. The next day turn on your shower and position the handle to the normal spot and time it till it gets warm. If it takes 20% more time to get to the shower, change out your shower cartridge. The cold water is overpowering the hot water due to a weak cartridge.
Question: Why cant i get a 5/8 inch female to female ends stating it on the picture it shows me instead of hose size
Answer: These are straight threads and there are no standards to be followed. hose size fittings are standard.I would hard pipe t thing using lock tight. Or solder a copper piece of pipe .probably 1 inch l copper with bridgit.I have filled 3/8 gaps witj no issues.
Question: Is the out put tempeture adjustable? What I want is slighly hotter water coming out the tap than
Answer: 120 degrees is about the max. The point of putting something like this in is to extend the hotwater for showers if you have a smaller tank. If you want hotter water for less duration. dont use this product just turn up your heater and add more cold via the tap.

No more long water lines and circulation losses because the units are installed directly at the point of use. The water is no longer preheated and stored in large amounts.That saves energy. And it saves investment costs: Long water lines, circulation pumps and hot water tanks are no longer necessary.

More Hygiene

Electric instant water heaters heat up the cold water to the perfect temperature within seconds, directly at the tap, as it flows through the unit. The heated water is used immediately and unused water is avoided in the water line systems. That’s why testing for Legionella bacteria becomes unnecessary. This is what makes de-centralised water heating more hygienic and efficient.

Great for Small Spaces

Water heaters are compact and lightweight and can be undersink or oversink installed - features a sleek and attractive design to blend seamlessly with decor, very friendly to any small spaces.
