Archive for June, 2009

water heater is electric and i installed it myself it is brand new it's wired correctly and the hot and cold are plumbed right it has been hooked up now for appx 6 hours and the water in the tank is ice cold?? i am so frustrated because i originally baught a tankless and that was a piece so i went and baught another 30 gal to replace my old 30 gal and now it's a piece i am going on over a month with no hot water and i am getting discouraged any help will be emmencly appreciated
filled water heater and purged all the air from the lines before i turned the power on, i've pressed the reset button a half a million times, i called it ever name i could think of and still nothing. i also shut the power off and upped the temp, when that didn't work i move it to a different slot in the breaker box. i even tried a different breaker.
ecectrical isn't my department i checked each leg not both at the same time each leg read 126. how am i suppose to check it

have you used a multi meter to see if you have 240 volts going into and receiving 240 volts? what are the thermostats setting on take a screw driver and adjust them til you here them click in and then listen for the hiss,that will tell you its heating,but make sure your getting 240 volts not 120 volts on each leg, test the wiring using the tester across both wires live,after all all you have to check is the thermostats and elements,not saying your dumb or anything like that but its easy to check the wiring the wrong way and think your doing it the correct way,did you fill the tank prior to turning on the power,i know you did but thought i'd ask,cause if you powered it up first as soon as the water hit those hot elements they fried.just asking.

It's a tankless water heater, so it shouldn't be holding gallons of water. It can provide 4.0 gallons per minute when it's heating the water going through it by 45 degrees Fahrenheit, or 2.3 gallons per minute when the water temperature is increased by 80 degrees Fahrenheit.

Do they work efficiently, save money, etc.?

Great product! However, make sure that you get a big enough one to run your washer, dishwasher, shower, and sinks at the same time. Most people that install this system have to install 2 units. It can get costly and tales a long time to re-coupe your expense.
If money is an; issue, I would recommend replacing your existing water heater with a highly rated Energy Star Water heater but also install the correct size water heater jacket.

The jacket will save an additional $5-$12 Per month and pay for itself in about 6 months.
