14 best tankless water heater accessories

Tankless water heater accessories are components and add-ons designed to enhance the performance, efficiency, safety, and convenience of tankless water heaters.These accessories can help you get the most out of your tankless water heating system. Here are some common tankless water heater accessories:

  1. Venting Kits: Proper venting is crucial for the safe operation of a tankless water heater. Venting kits include pipes, adapters, and termination caps designed to vent exhaust gases to the outside. The type of venting required (e.g., direct vent, power vent, or non-condensing) depends on the specific model of your tankless water heater.

  2. Water Filters: Water filters are used to protect the tankless water heater from sediment, scale, and mineral buildup in the water supply. They can help extend the lifespan and maintain the efficiency of the unit.

  3. Pressure Relief Valves: Pressure relief valves are safety devices that prevent excessive pressure within the tankless water heater. They release built-up pressure if it exceeds safe levels, protecting the unit from damage.

  4. Isolation Valves: Isolation valves allow you to shut off the water supply to the tankless water heater for maintenance or repairs without affecting the entire water supply system in your home. They are installed on the hot and cold water lines connected to the unit.

  5. Scale Inhibitors: Scale inhibitors or water conditioners are used to prevent the buildup of limescale and mineral deposits inside the tankless water heater's heat exchanger. This can help maintain efficiency and reduce the need for descaling.

  6. Remote Controls: Some tankless water heaters offer remote control options that allow you to adjust the temperature and settings from a convenient location, such as a wall-mounted control panel or a remote control device.

  7. Condensate Neutralizers: In condensing tankless water heaters, condensate is produced as a byproduct. Condensate neutralizers help safely neutralize the acidic condensate before it's discharged into the drainage system.

  8. Pipe Insulation: Insulating the water pipes connected to your tankless water heater can help reduce heat loss and ensure hot water arrives at your fixtures more quickly, improving overall efficiency.

  9. Recirculation Systems: Recirculation systems, including pumps and timers, can be added to your tankless water heater setup to reduce the wait time for hot water at faucets and showers. They circulate hot water through the pipes, ensuring it's readily available when needed.

  10. Service Kits: Manufacturers often offer service kits that include replacement parts, such as heating elements or gaskets, to maintain and repair your tankless water heater.

  11. Flush Kits: Periodic flushing of the tankless water heater's heat exchanger is necessary to remove mineral buildup. Flush kits include the necessary hoses and connectors for this maintenance task.

  12. Expansion Tanks: In closed-loop systems, expansion tanks help accommodate the expansion of water as it heats up, preventing pressure fluctuations and extending the lifespan of the tankless water heater.

When selecting tankless water heater accessories, it's essential to consider the specific make and model of your unit to ensure compatibility and proper installation. These accessories can help optimize the performance and longevity of your tankless water heating system while maintaining safety and efficiency.

User questions & answers

Question: How many psi is the pressure relief valve rated at
Answer: This pressure relief valve is set by manufacturer at 150psig and its BTU/hr rating is at 500k max. Make sure to use this relief valve on heaters that have equal or less input BTU/hr rating than the one provided here.
Question: good for outdoor use
Answer: I think the solid brass valve bodies will hold up well for indoor or outdoor use. Although, I would do more research to determine if it is acceptable to use the flex gas line outdoors (in terms of both physical ability to withstand damage and chemical ability to withstand chemicals and UV rays from the sun).
Question: will this work with Bosch
Answer: That is a question you are better off taking directly to the manufacturer to get the most accurate answer. I can tell you that I purchased this item and used it in my Rheem tankless water heater installation. I can tell you that all of these fittings are of the highest quality. I was very pleased with them. It is an expensive kit and I didn't need every part included. I could have bought individual pieces cheaper but this kit had everything I needed and I knew it was designed for my intended purpose so it was worth it for me to pay a little more. These particular fittings can cut out several of the plumbing steps included in your installation because the installation instructions tell you what kind of plumbing fixtures to use and how to install them but, looking closer (after I had done all of this extra plumbing work) I saw that these fittings were designed to handle these additional plumbing functions (such as your bypass drain fitting).
Question: What country are they made
Answer: The gas flex riser is made in Korea, the water flex risers are made in china but I have no tag on the brass valves as to country of origin. They have performed without any problem.

THIS IS WHAT'S INSIDE EXISTING WATER HEATERS.

For over 150 years, people have been heating water using electricity and metal heating elements. They rust, scale, lose energy efficiency, and eventually fail. Heatworks water heaters have no heating elements.

Instead, we use Ohmic Array Technology to heat water. Endlessly. On demand.

INTRODUCING THE MODEL 3 TANKLESS ELECTRIC WATER HEATER BY HEATWORKS

Powered by our patented Ohmic Array Technology, the MODEL 3 is a smart, electric tankless water heater that provides endless hot water on-demand for houses, apartments, and points-of-use. What sets it apart from other water heaters is how it heats water.

You won't find metal elements inside. That 150-year-old technology has one fundamental flaw: the metal heating elements get very hot and the minerals found in water stick to them. This causes energy efficiency loss, hot spots, and eventually the elements will fail. Instead, the MODEL 3 uses electronic controls to pass controlled electric currents through the water. This transfer converts electrical energy into thermal energy, creating endless water, on-demand. At the temperature you want. And because no scale forms, there is never a loss of energy efficiency. No metal heating elements to replace. No maintenance.

And as with all tankless electric units, the MODEL 3 only uses power when hot water is needed. Save time, money, and energy.

SMALL IN SIZE. BIG IN INSTALLATION OPTIONS.

The MODEL 3 installs like any other tankless electric water heater and can be used in new construction or as a replacement to any gas or electric tank or tankless water heater. Add it to an existing hot water system as a booster or install the MODEL 3 closer to the point of use for up to 10% in water and 25-40% in energy savings each month.

CUSTOMIZABLE BASED ON YOUR HOME AND HOT WATER NEEDS.

Another unique feature of the MODEL 3 is the ability to adjust it from 208-240 volts and 30 to 100 amps (6.2 to 24 kW) upon installation. The higher the amperage/power setting, the more hot water the unit can provide. Please make sure to reference both the expected temperature rise table and installation manual to make sure you have enough power required for your hot water needs before ordering.

ENERGY EFFICIENT

  • No scaling or rust
  • Only uses power when hot water is needed
  • Maintains its energy efficiency throughout the life of the unit
  • Heats water faster

OFFERS PEACE OF MIND

  • Get endless hot water on-demand
  • Requires NO annual maintenance
  • No elements to replace

MADE FOR TODAY'S SMART HOMES

  • Wi-Fi connectivity
  • Monitor while away
  • Though not required, download the Heatworks’ free mobile app to remotely control the unit
  • Digital display

User questions & answers

Question: What does the temperature heat up to and for how long? Does The water temperature heat up based upon the actual temperature of the water coming out t
Answer: We have ours set on 115, and it will hold that as long as there is water and gas
Question: what is BTU rating, is there and altitude restriction on this unit
Answer: 35,000 btus and there was no altitude restrictions on the info that came with the unit.
Question: Does this model have freeze protection for use in colder climates
Answer: Michele, yes, you DO need freeze protection! Without this feature, there is always water in the heat exchanger, and the low volume of water to high surface contact means this heater is more suceptable to damage than a tanked version which has a "cushion" of water to survive mild frosting, not deep freezes. Ronald, thanks! That makes me feel better, as we snow camp in the mountains at times where it warms up to 24 degrees by noon. 👍
Question: Does it work on both electric and propane
Answer: No, this is only run on propane. It doesn’t use much though. It’s very efficient.

User questions & answers

Question: How many Amp breaker is Required
Answer: No, the MODEL 3 was designed to run on 240V but can run on 208V or 220V. We do not have a product that will run on 110V. Please reach out to us at 1-888-506-2821 with any additional questions. You can also visit our website at https://myheatworks.com/pages/support.
Question: Had anyone tried using this off of a regular household plug? Ie a bathroom outlet? 15 amp breaker? Seems odd they sell a 3kw product with a 1.5kw
Answer: The number of units you will need to provide sufficient hot water is based on three main factors: 1.) The power set on the unit. The power (amperage) setting for the MODEL 3 can be adjusted between 30-100 A. 2.) Your incoming groundwater temperature. 3.) The flow rate of your fixtures in GPM and how many will be operating at a time. For each MODEL 3 set to full power (100 amps): • 3 gallon per minute demand will yield a 54 degree F rise in temperature. • 2 gallon per minute demand will yield a 82 degree F rise in temperature. • 1.25 gallon per minute demand will yield a 131 degree F rise in temperature. The average shower temperature is 105 degrees F. If you have further questions about your particular homes application, please email us at [email protected]

Kelaro Tankless Water Heater Descaler Kit with Flow-Aide

Like all appliances, tankless water heaters require regular maintenance for optimal performance and efficiency. With proper maintenance, they can last over twenty years.

This cleaning kit comes with everything you need to maintain your water heating system. It includes step-by-step instructions that are easy to follow and quickly connects to your tankless isolation valves using the supplied hoses.

Kit is reusable by simply replacing the cleaning agent. Calcium deposits don't stand a chance!

Mineral Build-up is Bad

Heater elements attract minerals from water and quickly add layers of scale during normal use. The layers get caked on and decrease the surface area available to heat up water.

Avoid Cold Showers

Scale build-up causes water to heat slower and decreases the maximum temperature of water coming out of your heater.

Scale will keep adding layers until the system is no longer able to heat water going through your tankless water heater - meaning cold showers are in your future!

Save Cash

Tankless water heaters don't run efficiently with scale and require more energy (gas or electricity) to run. Extra energy costs add up month after month.

You could hire a plumber to do the maintenance, or save even more - and do it yourself.

Annual maintenance using a Kelaro Flush Kit keeps your system running efficiently and saves you energy. Even better, the kit can be reused year after year - just replace the cleaning agent.

User questions & answers

Question: Does this have a winter use device (wud
Answer: 24W
Question: Does it run on both electric or propane
Answer: It requires 60Hz/110VAC and it is rated at 24W. Unfortunately for me, the HE is not listed by a nationally recognized testing lab, so the installation requirements are much more stringent. In my case the National Fuel Gas Code requires more clearance around it than I have in my water heater closet. So I returned mine.
Question: Can this be used year round in nc where outdoor temps can dip down to 0f? the inside of camper would stay heated
Answer: the cup holder is pretty large, so I think basic 12oz cups would fit fine
Question: i have a 16x16 open hole what door do i need

Question: Is there a recommended distance from the tankless hot water tank to mount it
Answer: The chemical is safe to use on an RV water heater. The capabilities to connect the hoses from this to your RV heater is unknown for us. If the water heater has 3/4" service valves it will work.
Question: This pan has a 1” cpvc socket, but i can’t find 1” cpvc to connect to it. my code prohibits pvc. how can i connect this to my 3/4” cpvc drain line
Answer: Dear Customer. To calculate maximum amp usage of the device. You take maximum watts and devide by voltage. Meaning that this water heater will use maximum 27.3Amp(3000w/110v). To find out what amp breaker is required you must do the same for all the other divides connected to the breaker and add them together. Best Regards
Question: Can this be used to drain the condensate and pressure relief valve
Answer: You are right, the math does not add up. I ran a 20 amp line with a 20 amp breaker. This heater draws 28.8 amps at all times. The flow does not reduce the amp draw. Need a 30amp, #10 wire,120v
Question: How do I install it on the wall? What kind of flexible piping is suggested from the pvc drain fitting to the drain 5ft away
Answer: 3 feet
