Ik ben nog even verder gaan zoeken over water ontharders en boilers. Nu alleen in het Engels:
Deze site is eigenlijk niet samen te vatten want alles wat hij schrijft is erg interessant. Zijn conclusie:
None of this guarantees that water softeners cause water heaters to fail though, so where does this “old-plumber’s tale” come from?…Another anecdotal factor to bear in mind is that “in the old days” when softeners lacked effective electronic controls, it wouldn’t be uncommon that a softener was returned to service after regeneration without being properly rinsed. This would of course induce a very high conductivity solution into the plumbing and create a corrosive condition within the water heater. Lots of water heaters were replaced, and the softeners were rightfully blamed, which inferred incorrect blame on ion exchange softening technology.
How does this all translate into water heater longevity? – Well, the first thing is that hard water can significantly reduce the longevity and energy efficiency of a water heater through scale formation, and softening the water will protect against it; BUT if that water is very hard, is highly alkaline, or has a low pH it can be corrosive after softening. As with all things, we must know and understand the details, for the devil is in the detail.

Oftewel, zacht water is geen probleem of zelfs voordelig, zolang het water maar redelijk pH neutraal blijft.
Powered anode rods, or impressed current anode rods, are made of titanium. While performing the same function as other regular anode rods, the powered option is not supposed to perish.
With a low current passing through the rod, the minerals from hard water are pulled from the water, but the corrosive process is essentially neutralized without the anode rod having to take on the damage.
As long as you have power, your tank is protected from damage. These rods are also intended for use without frequent maintenance, last longer than their sacrificial counterparts, and are intended to increase the life expectancy of your water tank regardless of water quality.
https://hvac-buzz.com/ano...-softener-considerations/Impressed-current anodes -- that's the technical name -- are not "sacrificial", so they are not consumed during use. They feed a very small amount of electricity into the tank to replace that produced by sacrificial anodes. The electrode is made of titanium. Interestingly, while sacrificial anodes are consumed more rapidly in softened water, powered anodes actually work less hard because higher conductivity makes it easier for electricity to flow between anode and cathode (tank steel).

Het lijkt er dus op dat Atlantic zich vooral wil indekken, want ook in Amerika en Engeland is hard-water een groot probleem en is het gebruik van een boiler gangbaar. Alle bronnen die ik vind geven aan dat een waterontharder bij
zwerfstroom anode geen enkel probleem is.
Overigens geeft Aquacell hetzelfde aan in een mailwisseling:
Plaatsing van onze waterontharder zal hoogstwaarschijnlijk geen problemen opleveren.
Als uw boiler een zwerfstroomanode heeft dan kunnen wij garanderen dat er verder niks zal veranderen naast dat u zacht water geleverd krijgt na installatie.
Ik ben benieuwd of ik ook Waterluxe zover krijg die garantie zo op papier te zetten

Nog wat aanvullende info:
SOFTENED WATER
Water softening is an ion exchange process that exchanges hard water ions like Ca+2 or Mg+2 for single-charged ions like sodium (Na+) or potassium (K+). Water softeners do not remove negative ions like bicarbonate and chlorides. So, what’s the benefit? When in solution with bicarbonate, sodium ions do not exhibit inverse solubility. Even when the bicarbonate ion breaks down upon heating to form carbonate, it is still over 30,000 times more soluble than calcium carbonate. So, as shown below, instead of forming calcium carbonate scale, the sodium and carbonate ions stay in solution to much higher concentrations.
Softened water is one approach to preventing scale build up in steam humidifiers. Water softeners remove hard water cations and exchange them for softened water cations like sodium ions. Also, softening water does not appreciably change the conductivity of the water, because for every calcium ion (containing two positive charges) that is removed, it is replaced with two sodium ions, each of which have one positive charge.
https://dristeem.azureedg...ts-handbk-en.pdf?sfvrsn=2If we consider the electrical conductivity of water with hardness ions (Ca, Mg) and the electrical conductivity of softened water, i.e. water only with sodium cations, then the electrical conductivity of softened water will almost always be higher than the electrical conductivity of the original hard water.
