14 best point of use hot water heaters

Point of use hot water heaters, also known as on-demand or tankless water heaters, are appliances designed to provide hot water directly at the location where it's needed, rather than heating and storing a large volume of hot water in a tank. They are commonly used for specific applications, such as supplying hot water to a single faucet, shower, or appliance. Here's what you need to know about point of use hot water heaters:

  1. Instantaneous Hot Water: Unlike traditional tank water heaters that keep a large tank of water hot all the time, point of use heaters heat the water on-demand. When you turn on the hot water tap, cold water flows through the unit, where it is quickly heated by an electric element or gas burner, delivering hot water almost instantly.

  2. Space-Saving: Point of use heaters are typically compact and wall-mounted, which saves valuable space compared to traditional tank water heaters. This makes them ideal for small apartments, under-sink installations, or in areas with limited space.

  3. Energy Efficiency: Tankless water heaters are more energy-efficient than tank-style heaters because they only heat water when needed.This can result in lower energy bills since you're not constantly heating and reheating water in a tank.

  4. Endless Hot Water: Since point of use heaters don't rely on a finite tank of hot water, you can have a continuous supply of hot water as long as the unit can keep up with the demand. This is particularly useful in applications where hot water is needed for an extended period.

  5. Multiple Fuel Options: Point of use heaters can be powered by electricity or natural gas (or propane, in some cases). The choice of fuel source depends on your specific needs and the availability of utilities.

  6. Installation Location: These heaters are usually installed close to the point of use, such as under a sink or near a shower. This minimizes heat loss in the pipes and ensures quick access to hot water.

  7. Flow Rate: The flow rate of a point of use heater determines how much hot water it can deliver per minute. It's essential to choose a unit with an adequate flow rate to meet your specific needs.

  8. Maintenance: Point of use water heaters generally require less maintenance than tank-style heaters. However, they may still need periodic descaling or cleaning to maintain efficiency.

  9. Cost: While point of use water heaters can be more expensive upfront than traditional tank heaters, the potential energy savings over time can offset the initial cost difference.

  10. Safety: Like all water heaters, point of use heaters should be installed by professionals to ensure they meet safety standards and local building codes.

Point of use hot water heaters offer convenience, energy efficiency, and space-saving benefits. When considering one for your home or specific application, it's important to assess your hot water needs, available fuel sources, and the heater's flow rate to choose the right unit for your requirements.

User questions & answers

Question: Is it necessary to connect an expansion tank to this heater (for safety purposes)? It states something to that effect in the user manual
Answer: The expansion tank for this heater is not required. Most people already have these installed in their homes but if not then it would be Ok without it as there is a pressure relief valve on top if something happened. GlobalTowne is an authorized Bosch distributor.
Question: would this be able to supply a shower
Answer: A standard flow shower head is around 2.5 gallons per minute. A low flow head is around 1.5 gallons per minute. The recovery rate for a 90 degree temperature rise is 6.8 gallons per hour! So even the 7.5 gallon unit would only provide 4 minutes of shower time before the temp dropped off dramatically. (even at the low flow rate..)
Question: Can be used "in-line with a large hot water source"? Would it help a large bathtub that runs out of hot water before it gets full from main tank
Answer: If your bathtub is bigger than your main heater tank, this unit isn't going to do much for you. It will add 2.5, 4, or 7 gallons to the capacity of your main tank, depending on which Bosch unit you buy. The 7 gallon unit requires a specially wired circuit. You will also get a little bit of lukewarm water that was in the line between your main heater and the Bosch unit. Unless your main tank is awfully small and your bathtub massive, the 4 gallon unit should work for you. Maybe a demand type thankless heater in your bathtub hot water feed would be a better choice, but be careful to size it properly for your desired flow rate and temperature rise. Also a tankless is likely to require special wiring.
Question: When this heater is connected to the hot water line, what happens with the cold water that was sitting in the pipes
Answer: When the tap is opened, the hot water in the unit flows out. The colder water that was sitting upstream of the unit, enters the unit to be heated. If the tap remains open, the newly heated water flows out, being replaced eventually, (depending on the distance to the main water heater), with the water from the main water heater. You will probably set the unit temperature to equal the main water heater temperature, if you want to keep a constant temperature, but other scenarios are possible.

Minimize Wait Time for Hot Water

Waiting for hot water at a sink located far from a primary heating source can be frustrating. Only having access to cold water from a sink is just not useful, and plumbing a hot water line to every sink in a home or business requires time and money. To get hot water where it’s needed, when it’s needed, a better solution is to use the Tronic 3000 T from Bosch: a point-of-use electric mini-tank heater. This heater can supplement a primary water heating source, or be used under a single sink. In fact, the Bosch Tronic 3000 T can be used for three different applications: as a sole water heating source for a single sink, as a supplement to an existing heater located far from the sink, and as a buffer installed in-line with tankless water heaters that experience intermittent cold water, also known as 'cold water sandwiching'. No matter the configuration, there’s minimal stand-by loss from this premium mini-tank water heater.

User questions & answers

Question: Ecosmart 8, location central texas, home workshop to supply hot water for dog bath and sink. personel use, not a business, 2 big dogs. will this work
Answer: I have no problem with ice for smoothie. I blend all other ingredients (including about 8 oz liquids - milk and yogurt) then add ice cubes one at a a time. This is easy to do as the blades are at the bottom so ice cubes can be dropped in from the top. May need to press cubes down toward blades with a spoon.
Question: Product description says #10 wire, reviews all say #8, which is correct
Answer: As long as you rinse it right away or let it soak for a bit if you're on the go and have to leave right away, it's fine. I am actually impressed by how well stuff does not stick to the inside. What I've been doing is using a long dish washing brush to clean down by the blades and using a regular dishcloth for all the other areas including the rest of the inside. Easy to clean. Hold the little piece on the bottom while scrubbing the blades with the brush so the blades don't move from the brush.
Question: Could this be used to slowly heat a small above ground pool? Just wanting it warmer
Answer: The one I received this rubber seal pops out every time you open the lid and it has since day one... Can't even check to see if you're finished without having to stop and try to put the rubber seal back in place which takes a few minutes each and every time.

3 Smart Steps for Endless Hot Water

Step 1: Determining your average inlet water temperature is important, this allows you to determine how well your unit will perform in your desired location. A lower inlet water temperature will require a higher kilowatt product.

Step 2: Next you will determine how many applications your unit can run simultaneously at your chosen location inlet water temperature. Tankless electric water heaters are sized for maximum simultaneous use, not maximum fixtures in your home.

Step 3: Determining specifications and electrical infrastructure is important because without the correct infrastructure your unit may not fit into your breaker panel.

User questions & answers

Question: Can this be mounted horizontal
Answer: How long does it take to heat the water when turned on?
Question: When we went to connect the water connector tube to the red ring hot water outlet it would not fit. There was a red tub in the outlet that prevented t
Answer: Yes, you are correct, one of the units I installed had the same issue with the red plastic fitting liner protruding, and it cannot be pushed in or removed. I solved the problem by filing the plastic down to just above the metal pipe. Make sure to keep it level and remove burrs. Another fix would be to use standard pipe fittings such as putting a street ell on the tank nipple then connecting your flex hose to that - use brass or stainless fittings and pipe dope.
Question: Has anyone used a t-valve to hook this to their toilet inlet line? I'd like to split the toilet line, install this, then attach my sprayer bidet
Answer: Yes you can, but you know, you can buy a bidet with a water on demand heater built in it ! much better and you are not reheating 2.5 gals of water after each use. Check on Amazon or Wish for a bidet, it is not expensive .
Question: Does it need its own breaker
Answer: Yes and no, it depends on where you are robbing the power from ,if it is from a circuit with very little use like bath wall outlets only ( like I did ) I would say no ,but if its from a circuit with heavy use, I would say yes, also what are you going to use the hot water for ? in my case, I use mine at the wash basin only so it is not heating continuously. .

Answer: I have the 4 gallon tank and it is not too bad for the reheat
Question: Can I reduce the pipe's size from 3/4 in to 1/2 in without any negative effect on the unit
Answer: No harm to unit.....Max water flow will be reduced a little.
Question: Can i use this to replace a small rv hot water heater
Answer: Yes, but realize that it's electric and draws quite a few amps, most rv water heaters are propane.
Question: The Manual request for the ES8 a 20 Amp breaker and 12GA wire. The wattage however is 1440 with 12 Amps. Why then 20 Amp breaker and not
Answer: I would use a 20 amp circuit with 12 ga wire but there are no inrush concerns with a resistive load. A heating element does not have a higher initial current draw like a motor. It draws 1440 watts or 12 amps at 120v. Since 14 ga wire must be fused for 15 amps, this device by itself is already at 80% of the circuit’s capacity.

User questions & answers

Question: How is it that this is energy efficient if it constantly maintains a heating temperature that you can use on demand? Is there an off/on switch
Answer: Most rinnai tankless weather it is out door or indoor, have a control board to adjust temp and either on or off
Question: I connected the water in the water heater already. But the pressure didn’t pumt the water to the sink
Answer: It can definately be out doors in freezing temps, tho power failure arent good for it while in a freeze, tho keep in mind it will use alot more energy for frost protection, indoor units are safer amd more efficient in this case
Question: Can I connect the water intake on this unit from the hot water supply from my house water heater? The house heater is very far from kitchen sink
Answer: I bought model V65EN. It came with a wired digital controller. The installer did not run the wire into the house and mount the controller indoors. He simply set the controller at 120 degrees and left the controller inside the unit. If I want to change the temp, I have to take the cover of the unit.
Question: Will this work for an outdoor shower
Answer: Good place to check for info like this is Wikipedia. Here is what they say: Energy efficiencieseditMore tangible cost savings are defined when comparing the energy efficiencies of gas heaters with low NOx emissions with conventional flued types. Gas heaters with emission problems are flued and inherently lose substantial energies in the form of hot flue gases to the atmosphere. In addition, the choice of placement of flued heaters is greatly impaired due to flue installation restrictions.In contrast, dedicated low emission gas heaters do not require a flue system. Furthermore, with the introduction of oxygen depletion sensors and thermostatic controls, they do not place critical reliance on ventilation as previously was the case. These heaters can be positioned more conveniently and centralised to affect optimum warm air distribution. By definition unflued low NOx gas heaters are 100% efficient as all heat energy released from the flame is converted to useful heat.Hope this helps. June

3 Smart Steps for Endless Hot Water

Step 1: Determining your average inlet water temperature is important, this allows you to determine how well your unit will perform in your desired location. A lower inlet water temperature will require a higher kilowatt product.

Step 2: This product is fixed flow, which means that the output temperature rise of this product is determined by flow rate of the application. This chart gives you the expected temperature rise for various sink flow rates from 0.5 to 1.5 gallons per minute.

Step 3: Determining specifications and electrical infrastructure is important because without the correct infrastructure your unit may not fit into your breaker panel.
