Difference Between Hydro-Shark and Tempra

[Cougfan]

Can someone explain to me the difference between the Hydro-Shark 3 and the Tempra. They appear to both be made by Stiebel Eltron, and they look the same.

 

[Fun pain]

I have a similiar question, What size are you talking about?

I am looking at the, Stiebel Eltron DHC-E 8/10... HydroShark 3 SH3-07,


they seem to be exactly the same.... but prices are doubled for hydroshark 3 over the DHC-E 8/10...


anybody with first hand knowledge or experience would be great?

I am looking at the 12-15kw size. I may try calling Stiebel Eltron and asking them. I will let you know what I find out.

I just talked to Stiebel Eltron. They said that there is no difference between the HydroShark boiler and the Tempra boiler. The "Hydroshark" has a different name because it is part of the "hydrosmart" package (turnkey). The boilers are the same.

stiebel eltron are a pretty huge european outfit, they make a ton of stuff that gets relabeled by other outfits and sold on .. for example the controller for veissmann dhw solar panels is made by stiebel eltron .. my veissmann purge cart is made by a company called zuwa .. it's common business practice for large companies to buy the ingredients and repackage them .. the big three don't each have a factory that makes wiper blades, they buy them from whoever and slap them on their junkers before they sell them to the rest of us

obviously the more hands stuff goes through the more something is gonna cost

i'm not a fan of using those tiny, point of use, instant hot water machines in a radiant scenario .. they are designed to be bolted inside a vanity and give you enough water a few minutes a day to wash your hands after you've drained the snake .. but if you must, then by all means use the stiebel eltron unit, their stuff is very good quality

There is a difference between an instant hot water heater and a boiler.

Rheem makes instant water heaters for 150$ and these SE boilers are more like 600$. Different animals. Same end result though, electric to heat water in a flow through device.

Stiebel Eltron has been producing the Hydroshark boilers for space heating for quite awhile now, as do several other companies. I have a Hydroshark keeping my shop warm right now, no issues in 5 winters.

I'm really not sure how many ways there are to build a heater that uses electric heating elements. An element or a few elements housed inside a some sort of chamber that passes water through, and some control circuitry, it's not exactly rocket science, and there's only so many ways to package it.

Stiebel Eltron is a big outfit as suggested and they make "big" and "small" space heating boilers and domestic hot water heaters (called boilers in most of the world).

It is really all in the controls, proper application and installation.

The Hydroshark boiler is heavily marketed to the DIY market and the original Stiebel Electron line to the engineers and to a lesser degree the trades.

Just looked at a DIY HydroShark "package" today. It was big enough to heat the two car garage, the 800 sq.ft. basement and heat the driveway for snow and ice. With a couple of man-days and a few parts it will work again.
