If you ask me, and chiefly speaking about root-analysis, to anyone who is wondering, water heater / hot water system don't really matter much from one brand to another.

This is because the technology that is designed to generate the pressure and heat has been centuries old ---- since the law of its very own physics founding itself until now, which is really a mature and stable technology. Primarily, the pressurization aspect, and likely the heating contraption also.

It hasn't changed, because, it's proven ---- cost-wise, and logically functional and explainable. And moreover, it's fruitless to spin the wheel and reinventing the exit.

Mechanical engineers would know that brands don't matter much. Better yet, they already know a cheap China-made pump works well enough for them.

What you need to know however, is the material usage behind the water heater or hot water system, and any patent for the unique selling point of the product you're eying on-----usually to protect the electrical component to keep it from destruction, while the material usage is what helps water heater pump resist against thermal radiation / expansion / contraction / wear and tear / thermodynamics.

These days, individual household products are well-fitted with micro pump technology and you see this in car jet washing, to fish tanks, drinking filter, etc, and you get the same physics application but in different sizes. Because there is more money to be made fitting into micro segments. biggrin.gif

Hope it helps. smile.gif

In concept, any newly manufactured and legally registered cars will be able to take you from point A to point B.

In reality, however, there are really bodo designed water heater.

Lesser known brand #1, out of the box the filter cannot REPEAT cannot be affixed/tightened properly on the inlet pipe of the WH without added modification. Metallic/chromed shower hose and shower head was supplied.  rclxub.gif

Lesser known brand #2, has a terminal block for show i.e. not following the usual convention of having a drip loop to prevent water ingress, instead L & N terminals are SUPPOSED to loop downwards straight away after entering the WH unit and are SUPPOSED to be connected directly to ELCB. Any competent engineer will not split the wires into complete 180 degrees direction sharply; and it freaking negates the whole point of having a cable clamp to fasten the incoming cable since you have to literally strip A LOT of outer jacket insulation away in order to have the wires in 180 direction. Plus, in no other water heater that I have installed, you need to connect the L & N to the ELCB instead of the proper mounting point i.e. the terminal block for all LNE wires.

Lesser known brands #1 & #2 both CANNOT be centered horizontally over the water point pipe, because they so cleverly put the one and only "sole" TOP mounting screw smack in the center. So the client needed to pick a side (left of OR right of) away from the center pipe of water point for the WH mounting.

The WH is a decadent old device, but even simple things like cable routing and mounting holes cannot even get it right  laugh.gif

TLDR, just get the cheapest Pana push start model is the best, clean installation, everything is plug and play, unit can be centered right above the water point tap without punching holes in the water piping.

Don't fall for the scam of fancy plastic cover exteriors yet horrible design, or undersized diameter chromed metallic shower head/hose which tbh, I think my pee has stronger water pressure whistling.gif

This is why we have ISO standard, ANSI, and IEC for a reason... These no-name apparatuses get scrutinized by world-regulated bodies...

I just summarized your observation problem in one sentence. biggrin.gif
