Tankless Water Heater Miami Gardens


http://mattknowsthat.com/ One of the most common questions I get asked, by builders and homeowners alike, is for my opinion of Tankless Water Heaters. The short answer is YES, I like them, but the long answer is, “It Depends!” Watch this video to see what those variables are.

    Great video. What do you feel is more energy efficient, an electric
    tankless system or a gas tankless system? I am not sure if this is what you
    were addressing but do any units come with on demand options? Meaning,
    pushing a button (or an auto sensor) at a hot water source and the unit
    heats the water but is recirculating the unheated water? Like the D’Mand
    systems?

    In terms of “efficiency” technically the electric ones are efficient, but
    you need to remember that even if an electric water heater is almost 100%
    efficient, the utility is charging you for all the energy loss of getting
    the electricity to your house, so they’re a LOT more expensive to operate.
    In addition, the load requirement of a whole house electric tankless is
    about 170amps which is another whole service panel! If you have nat gas,
    that’s the way to go. I do like the D’mand systems too.

    I have a Stiebel Eltron Tempra Plus 29, tankless (electric), since Aug
    2009. Worked fine till Sept 2013. Now shutting off constantly. Trouble
    shooting; got the utility checked 200 amp service. Fine. Flushed the
    heaters out with white distilled vinegar, and after an hour the vinegar was
    still clean; soft water in Portland, OR. The unit fires up then I get a 2
    minute shower and it shuts off. Then I reset and get another short burst of
    hot water. Could this be a thermostat? Suggestions?

    Could be the thermo, but I would guess either low water pressure, or a
    faulty water pressure switch. These units have a water pressure sensor that
    will shut off the heating element if the water pressure drops below a
    certain threshold to prevent boiling the water instantly when it hits the
    heat exchanger which would cause a steam pressure problem. You can buy a
    water pressure gauge from professionalequipment dotcom and check the
    pressure. Let me know what you find out.
