Thanks for asking Valerie, National Steel Construction Electric Water heaters are not a brand with which I'm familiar - I'll do some research to see what I an find.
Attach a photo of the heater and another of its data tag - that will help us find an answers.
Please tell me also the country and city where the heater is located and also the age of the building itself.
The company itself operated in the U.S. at least from the 1950s according to trademark research.
Their water heater brands included
National
Doublex
Elektro-flo
Glasteel
No. 595,548. National Steel Construction Co., Seattle, Wash. Filed Apr. 11, 1950. FOR AUTOMATIC ELECTRIC WATER HEATERS. Claims use since July 1924.
National Steel Construction Co. (Water Heaters) was bought by or absorbed into A.O. Smith water heater co. in 1979
Interim guesses try to spot a rasonable year in the serial number you gave - 76 62 or 70 - we're looking further, pending your answer to my questions.

IMAGE LOST by older version of Comments code - now fixed. Please re-post the image if you can. Sorry. Mod.

Or if you prefer you can call the company directly - I include the HTP SuperStor contact information below.

This article series decodes the age of water heaters for domestic hot water: geysers, cylinders, calorifiers, or 'water heaters' while you are asking about the age of a forced air heating system for heating the interior space of a building.
Using the search box just above to look for 'FURNACE AGE' finds

On 2016-07-16 by (mod) age of Hotpoint electric water heaters

Judy for Hotpoint electric water heaters, the age is encoded in the heater's serial number, not the model nor catalogue number.
Take a look at the data tag on your heater.

If it is in the form RN0603123456 then the age is encoded in positions 3-4-5-6 starting from the left - so my example would be M M Y Y or 06 03 or the 6th month of 2003.
Some GE and Rheem heaters also use this encoding pattern.
As your heater is an old one it may use a different scheme. Use the page bottom or top CONTACT link to send me sharp photos of the data tag and of the whole heater and I can look at it further.

On 2016-07-16 by Judy

We have a Hotpoint Electric Water Heater Cataloque number 100WBSC521035. It was here when we bought the house 25 years ago. It says 50 gallons on it but it is the size and shape of the washer and dryer which sit on either side of it. I am worried that it will cease to work sometime and I don't have a clue where to look for a similar new one.

Question: what about water cylinder tank warranties?

(Oct 11, 2011) sharon said:

need to know about tank warranty

Reply:

Sharon see

The warranty period and terms of your specific water tank depend on its model, age, and of course proper installation. Typically you can find that information in the installation manual and papers for your unit, or if you don't have that information, you'd contact your heater's manufacturer and give them the model and serial number of your water heater.

We are worried about our hydronic water heater. Our neighbors had severe water damage when their water heater had a major leak while cold water kept flowing into the heater. Their system is similar to ours. We are going on vacation and wonder if we can turn off the cold water intake so that if the water tank develops a leak, at least we won't have a flood. Can we do this safely?

Reply:

Anon,

If we assume that your Envi-ro-temp water heater is an Envirotron product I can give this information from CDA's technical reference cited in our References section:

Envirotron went out of business around 1980 - which would your heater at least 33 years old. The current incarnation of the Envirotron name is a company that provides 'green technology education and resources' and has their own website with that name.

There is also Solatherm-Envirotron, 1983
Solar Hot Water System for a Newspaper Building: Final Report
Solatherm Envirotron, 1981 [book about 151 pages)
This company published a number of solar water heater studies and documents.

Is your heater a solar unit?

In any event, from the serial number serial # 9812126163 I would bet your heater was made in year 98, month 12, or December 1998.

Details are at ENVIROTRON WATER HEATER AGE
