    Default Geyser Titianium Elements - are they any good?

    Hi, I've been looking into getting a Titanium element and dedicating 3 250w panels to it... has anyone got any experience with this?

    Thank you!

    Running since Dec, so far so good - you probably also need to get a Geyserwise controller to monitor the temperature & manage the dual element on the timer for winter

    Default RE: where...

    I'm getting mine from Delano van Wyk <[email protected]> Cape Town. A friend of mine bought an Infinisolar 3kw Plus from him, I have one on order and he's been brilliant to deal with.

    If you use him please let him know how you found him :-)

    Lots of experience and info on this issue on this from.

    Just be careful of DIY solutions for switching the DC to the element.

    NO temperature control with anything resembling a physical contact. Eg relay, thermostat etc.

    I got a quotation on a system from TFS Solar it works with 4 x250w solar panels and a duel element 220vac/48vdc. My thinking is that after the water is nice and warm you have a couple of hours of solar power to use for other applications. As i bought myself a grid tie inverted now I will probably not go that way. But I would think it is worth looking into. depending on the price difference with a normal sun geyser setup.

    The quote I got was about R23000 for the full setup (excl geyser )

    i can mail you the one i got but that includes a lot of crap I did not need. the total came to 19k the element control box is and the thermostats plus a adapter was +-3k with the timer included. the Solar is +-r10/watt. And you use your own geyser . with the V1 Control box you can use the extra power to charge some batteries for the load shedding crap going on..

    Why titanium?

    ositive Temperature
    Co-efficient (PTC) chips as the heat source.
    Heating elements made with PTC chips do not
    use resistance wire as a source
    of heat. Instead, it uses a number of ceramic
    PTC chips as the heating source.
    PTC heating elements are ceramic chips that
    have self-limiting temperature
    characteristics. As the PTC chips heat up it
    reaches a designed temperature
    at which the heat output decreases drastically
    and prohibits it from getting
    hotter. As ambient temperature increases and
    less heat is dissipated, the
    resistance of the element will increase
    culminating in a near zero current
    draw at its designated temperature.

    Our PTC elements are manufactured from Ta2 industrial grade
    Titanium and due to its temperature limiting characteristics lime
    build-up is insignificant. It has a design life of ten years. It can
    operate in dry air and will never burn out.

    How does this work?How can it be as effective as a 3kw element in a 150l geyser?I am bad techno jargon so I am trying to understand it in laymens terms.If you have 4 x 250w panels on the roof is it regarded as a 1kw system?.
    Does it heat much slower than a normal element but not matter because unlike flat collectors it can use the early morning sun and the late afternoon sun.Is it one element or two elements but can be run on both ac and dc.

    Its a dual ac/dc element, geyserwise markets them, manufactured in PE. Cost about R1600+vat.

    A word of caution w.r.t these elements: They work REALLY well but the installed costs roughly the same as a whole new solar thermal geyser system
    Electrical geysers are designed to last 5-years.

    If you retrofit this element to the geyser you automatically void all warranties on your electrical geyser

    When the geyser fails it becomes the property of your insurance company. The plumbing company will simply remove the geyser (Along with the expensive element) and install a new geyser with a standard electrical element

    This is really cool tech but it is stupidly overpriced and youll probably lose the element when the geyser fails

    I have a w e geyser . It is a solar geyser.Generally solar geysers last longer than normal geysers.My thinking is if I had four panels on the roof and I had one of these dual elements I would then have in theory two working solar systems. I would hope that a hybrid system like this would make my geyser almost escomb independent.
    Then I could maybe use the pv solar panels to run the lights and tv in my house.
    In other words it would be a more versitile system and warrant the expence.
    I dont know who to talk to about these systems

    The element is not that expensive, insurance will put you back in the same position you were - all they require is invoice with warranties when you done installation. If under warrenty - supplier replace, if out of warrenty insurance replace, if geyser fails & element is fine - take out element & put in new geyser.
    The biggest cost is the solar panels & they have 25year warrenties, not sure what warrenty you get with normal solar geyser? ..& panels can be used for other purposes to generate electricity where solar geyser can only be used for ..well, hot water..
    With the current electricity crisis, I would say it is a no-brainer if you have the $$ to spend

    I found its cheaper to retrofit your geyser with a flat plate collector R11k vs the ac/dc element Kit R16k. Both exclude installation.
    Anyone else know if R16k is the normal going rate?

    Funny enough its cheaper to retrofit a geyser R11k and buy a new geyser R3k than to buy a complete unit for R24k. This excludes installation and not taking into acount how much better the complete unit's tank is.

    After seeing that video posted, if I go the dual element route then an inverter would be nice to go with it for load shedding

    Quotes I got was around R2500 for a 300 watt panel. If you need three panels and the element it shouldn't cost more than R10k if you DIY. A Geyserwise controller was around R1k last time I checked.

    A lot of the cost is for the installation.

    Also, if the geyser fails, remove the element before the insurance guys replace it.

    Hi all,

    Is this solar only? If so, what happens with a few days of cloud?

    Dual element so will use Eskom if insufficient light for PV

    Has anyone fitted these yet?
    How well does it work?
