14 best hot water tank for boat

A hot water tank for a boat, often referred to as a marine water heater, serves the purpose of providing hot water for various onboard applications, such as showers, sinks, and galley use. These water heaters are specially designed to meet the unique requirements and space constraints of boat installations. Here are some key points about hot water tanks for boats:

  1. Types of Marine Water Heaters:

    • Tank Water Heaters: These are the most common type and work by heating and storing a specific volume of water in an insulated tank. They are available in various sizes to suit different boat sizes and usage needs.
  2. Fuel Sources:

    • Marine water heaters can be powered by various fuel sources, including electricity, propane, or diesel. The choice of fuel source often depends on the boat's setup and the availability of fuel.
  3. Installation:

    • Proper installation is crucial to ensure the safe and efficient operation of a marine water heater. It should be securely mounted in a suitable location on the boat, typically in an accessible but out-of-the-way area.
    • Marine water heaters must be installed in compliance with safety regulations and guidelines to prevent accidents.
  4. Heat Exchangers:

    • Some marine water heaters feature heat exchangers that use the boat's engine coolant system to heat the water in the tank.This is a common method for heating water while the engine is running.
  5. Electric Heating Elements:

    • Electric marine water heaters have heating elements, similar to those in residential water heaters. They require a source of electrical power to heat the water.
  6. Capacity and Size:

    • The capacity of a marine water heater is typically measured in gallons or liters. The choice of capacity depends on the number of people on board and the hot water demands.
    • The physical size of the water heater is crucial because space is limited on most boats, so it must fit comfortably in the designated installation area.
  7. Safety Features:

    • Marine water heaters often come equipped with safety features such as pressure relief valves and temperature controls to prevent overheating and ensure safe operation.
  8. Maintenance:

    • Regular maintenance is essential to keep a marine water heater in good working condition. This includes flushing the tank, checking for leaks, and ensuring the heating elements are functioning correctly.
  9. Energy Efficiency:

    • Some marine water heaters are designed with energy-efficient features to conserve power or fuel, which is especially important on boats with limited energy sources.

Having a reliable hot water source on a boat is essential for the comfort and convenience of those on board. Marine water heaters are designed to provide a steady supply of hot water, making life on the water more comfortable and enjoyable. Proper installation and maintenance are key to ensuring their safe and efficient operation.

Jabsco Bilge Marine Pump

Jabsco

Based on 102 reviews Check latest price

Product description

Accumulator Tank. This Accumulator Tank is intended for installation in any pumped water system controlled by a pressure switch. For example, PAR-MATE 2.5 or any Jabsco pressure pumps as found in boats, RV's, motor caravans, coaches and similar applications. The Accumulator Tank smoothes water flow and reduces on/off cycling of the pump by lessening the variation in pressure and flow between the pump and the outlets in the system. The even flow of water gives better control of hot water temperature especially noticeable with instantaneous gas water heaters and with showers. The reduced on/off cycling reduces noise from the pump motor, and from shock pressures (pipe hammer). It also reduces battery drain, and gives longer pump life. Features:. Internal Bladder Smoother and More Even Flow Quieter Water System Better Temperature Control Longer Pump life Lower battery Drain Simply fitted to new or existing systems Compact size Snap-in port fittings include both: 1/2" barbed hose fittings and 1/2" threaded hose fittings Tank: hygienic, light, compact, impact and pressure resistant plastic construction.

  • Smoother flow, quieter water systems
  • Internal rubber membrane eliminates maintenance and allows universal mounting
  • Better control of hot water temperatures
  • Simply fitted to new or existing systems, snap-in port fittings
  • Pressurized 1 Quart (1L) Accumulator Tank

User questions & answers

Question: Can this be installed at any angle or sideways
Answer: It's a pressured chamber, so it can be installed in any orientation.......
Question: Does this hold up against caustics like bleach
Answer: So far it has 3 years on off the grid seasonal cabin. I add bleach to my holding tank to be safe and no pump issues t all.
Question: What are the dimensions of the tank
Answer: , about 4-5",in diameter and 12-14 tall has two connection witch I only needed one was hard two fine the fittings for it but they are there
Question: Would it be worth putting two of these in
Answer: Personally I would not. If you want more volume find an accumulator tank for a reverse osmosis system (2 to 3 gallons) and install that. It's probably half the price as well. I did this after the plastic one failed in a few years.

User questions & answers

Question: What is the recovery time if the 7 gallons of hot water is used
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.

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: 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.

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: I understand the shutoff pressure is set to 65psi (adjustable). What is the turn-on pressure
Answer: Yes. But you need to add a filter for the pump.
Question: What is the procesure to adjust the shutoff pressure
Answer: 110 degrees
Question: Can i use this pump for raw sea (lake) water from a seacock to flush the toilet
Answer: It depends. How flow/pressure do you want after the 12 foot rise? I use this pump to lift water about 8 feet through high pressure irrigation hose with no problems. At the end of my rise is a low flow application and the pressure switch cycles the pump off/on and I decreased the pressure switch. If you leave the pressure switch alone I am sure you can move water 12 feet up. I would reduce the outlet hose size. Not sure how much flow you will get but it will not be a fire hose for sure.
Question: What is the max water temperature the pump will handle
Answer: You can use a car battery, or you can buy a 110 to 12v dc converter.

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
