Lights flicker


Depending on the size of the service in the house this could be a normal condition. Most newer homes have at least a 200 amp feed from the power company. If it is older it might only have a 60 amp( usually glass or cartridge fused) or 100 amp service. Could also be a loose ground or if the unit is grounded by just a conduit connection. May need to have a ground run from the breaker panel to the water heater.

Installation: Electrical Requirements


13Mb product manual is a big download ... electrical info page 13:

Recommended both water heaters require dedicated single-phase 15 amp 120Volt line with correct polarity. This is 14 gauge wire and 15 amp breaker for each unit.
I would put both water heaters on surge protection and GFCI. Most water heaters are not protected from surge, and manual says line noise can affect operation of water heater.
Your local code would say if GFCI is required. Install GFCI breaker in main panel if required.
Install inline surge protector: Or add main breaker box protection.

How to wire tempra 24 plus


1) Copy following link for wiring tankless electric water heater:
http://waterheatertimer.org/How-to-wire-Tankless-electric-water-heater.html

2) Look at label on side of unit for total KW

3) Product manual shows 24 Kw or 24,000 watts
24,000 watts divided by 240 volts = 100 amps
So your service panel must be about 250Amp rating to support this tankless electric water heater.
http://waterheatertimer.org/pdf/Tempra_tempra-plus-Tankless-electric-water-heater-manual.pdf

4) Look inside the unit to see how many L1L2 terminals show.
You should have two sets L1L2 terminals
http://waterheatertimer.org/images/Terminals-2-tankless-200.jpg

5) You need TWO 60 amp double pole breakers to supply power to this unit.
This means you need TWO #6 wires from one breaker going to L1L2.
And you need TWO MORE #6 wires from 2nd breaker to other set of L1L2 terminals.

6) Add comment for more help Jan 2013

Want to raise the water temp


Stand alone water heaters have temperature controls in different locations.

11_23_2012_12_50_47_pm.jpg
Most residential electric water heaters operate on 240 volts. Please, shut off power first whenever you need open or remove panels for adjustments or servicing.

"Traditional" electric water heaters have them behind removable panels - like the top and bottom gray panel on the water heaters on the right side of the photo. Both panels have adjustable controls behind them and both should be adjusted to the same setting.

Some newer electric water heaters use electronic controls. These may be accessible without removing panels and even have digital displays. Others have controls that are located on the top of the heater - behind a panel. Electronically controlled water heaters may or may not need to be powered on when making adjustments. Check your manual if in doubt.

Gas (propane & natural gas) type water heaters have the temperature control on the gas valve. There are often two controls on the valve, one for the pilot (off, light and on positions) and a second for temperature adjustment.

A tankless water heater built into your home's furnace is controlled by an "aquastat". An aquastat is a fancy term for a thermostat to control water temperature. A typical aquastat is mounted directly on or very near the furnace and looks like this:

11_23_2012_1_08_47_pm.jpg
Inside, are several temperature settings. Here's a photo of the interior of the Honeywell aquastat:


11_23_2012_1_12_16_pm.jpg
The Hi dial should never be set to a value lower than the Lo dial. "Safe" settings are Hi = 180, Lo = 160 and Diferential (above "Lo") = 10. You'll need to tweak these up a bit to make water hotter. You should read more about settings for these aquastats here. Skip down to the section titled "What Settings To Use on a Heating Boiler Aquastat Combination Control"

I hope this helps & good luck!

The black wire on the inside panel sparks


You posted 2 questions.
Add a comment to clarify problem
One question says black wire is sparking is inside water heater, and this question says black wire is sparking inside the panel and is posted under WH40 water heater timer.

If wire is sparking, then it is not attached firmly, or wire is not attached correctly, or there may be too many amps drawn across the terminal.
WH40 has 40 amp terminals and will handle all residential water heaters.

Open following links for instruction how to avoid sparking, and avoid fires inside timer:

I need to know the breaker size and wire gauge and number of wires needed for a bosch ae125 water heater


According to the user manual below, it's a 50 amp heater, therefore, you need 6 AWG electrical cable and a 50 amp double pole (220 volt) breaker in the main service panel.

You need two hot wires and a ground wire. The cable would be specified as 6/2 w/ ground. The 2 hot wires in the cable would be red & black or black & black -- these attach to L1 & L2 respectively. ( L = Line )

More info, let me know.
