9.Titan – Electric Tankless Water Heater 220 V 54 Max Amps

The Titan N-120 is the most popular model for average size homes. This space saving water heater will provide “endless” hot water for your entire home, apartment and other locations. As the Titan only heats the water when it is needed your energy savings on hot water can be up to 60%!

You won’t have to worry about running out of hot water for your guests after repeated showers! The Titan is recommended for warmer climates where the incoming water temperature is above 65 degrees.

Pretty easy install, no need to open up the box to connect electrical. You’ll need a 60 amp electrical disconnect box (ten dollars), 1 line of 6/2 wire (2 dollars a foot), a 60 amp double pole breaker ( just above ten dollars), 3 cable clamp connectors (well below 10), Teflon tape for PRV (2), and a pressure relief valve (PRV) (11 to 20) and the fittings to put in the PRV (varies but probably around 25), some cable staples to hang the wire, and some #8 screws to mount the tank and disconnect box.

Inlet/outlet is 1/2 and big box stores around me usually only carry 3/4 PRV. I used a corregated steel pipe connection to the inlet/outlet instead of the supplied compression fitting. The inlet connection kept giving me a small leak, so i had to use some blue blocker + teflon tape to shut it up.

no larger than a phone book , unlimited hot water , cheaper electric bill than standard water heater ,( it only uses electric when hot water is used ).One bathroom, one dishwasher, one washer, one person- hot water all day everyday all the time.

7.Stiebel Eltron Tankless Water Heater – Tempra 24 Plus – Electric, On Demand Hot Water, Eco, White, 20.2

TEMPRA 24 PLUS – This specific model is 24kW, 240V/208V, requires a min. recommended household electric service of 150 A, and offers an output water temperature of 68˚ to 140˚F. Check our guides below to compare features of our various Trend and Plus models, each available in different kW levels.

The Stiebel Eltron Tempra 24 Plus electric Tankless Water Heater features exclusive Advanced Flow Control German patented technology invented by Stiebel Eltron to automatically maintain water temperature for constant comfort. It’ll reduce flow slightly if hot water demand exceeds capacity to ensure that hot showers will never be interrupted.

Tempra 24 Plus will typically use 15-20% less energy compared to conventional electric tank water heaters. Although, it’s possible to save significantly more energy depending on personal home usage habits. The difference is that conventional tank water heaters continually store hot water, and as a result, lose 15%-20% of the total energy consumed to the environment around them.

This is called standby heat loss. Tank water heaters that use gas or oil are even less efficient, because they also lose heat through their vents to the outdoors. Our tankless water heaters do not need venting, and will not store hot water, waiting for you to use it.

They operate on-demand to provide continuous and endless hot water when you need it, and not waste energy when you don’t. CERTIFICATIONS INCLUDE – ANSI/UL Std. 499, CSA Std. C22.2 No. 88, ISO 9001, WQA tested & certified against NSF/ANSI 372 for lead free compliance.

Under normal power-on conditions, the water flow turns on, the water heater displays the temperature, but the temperature does not rise, there are 2 possibilities: the first is that the temperature control switch (overheat protection switch) inside the water heater has tripped. Control switch, it can be restored. The other is the heating tube failure, replace the heat tube 2.

If there is a display of no heating, the display shows rotating, but no temperature is displayed, indicating that the water flow has not passed through the water heater, or the water pressure is too low, and the water pressure needs to be adjusted; , Then check the water heater inlet turbine, it may be that the turbine is stuck, causing the water heater to not start.

It is recommended that the length of the water heater inlet pipe should not exceed 3 meters. If it exceeds, there may be a water pressure difference due to the length of the water pipe, and the water pressure is not enough to start. (If the water tank is used for water, the water tank is required to be placed higher than 10 meters to make the water pressure Reached the start value).
