    2 Gallon electric water heater.

    Please see attached pictures, this is a 2 gallon electric water heater used instead of a boiler and is only serving 1 towel rail in an apartment building. I did not do the install, but he is having problems with air. I have been back a couple of times and removed the air, but the problem seems to keep reoccurring - I am thinking of adding 1 small spirovent or equivalent air eliminator and bring the make up water and expansion tank in at the bottom of the spirovent.
    This may seem simple, but I have never seen a 2 gallon electric water heater used instead of a boiler before. Anyone see any problems with this?
    Thanks in advance.

    Seems like....

    a lot of work. An electric towel warmer would have been a simpler approach. I would add a hy-vent where the PRV is and add a 1/2 cup of dawn dishwasher detergent. 99% chance that works.... Fix is from Mark Eatherton.

    OK...

    I agree with above, an electric warmer would have been cheaper and easier.

    simple question.... which was is the heater installed? the correct way? and your picture is sideways or.... is the heater laying on it's side?

    If the heater is on it's side... your never going to get the air out, it's trapped in the heater... big ol air pocket, reinstall the heater the way it was intended and you fix your problem.

    If that towel warmer is installed sideways

    it must be holding some kind of quadrature gravity towel.

    I did

    A temporary hook up with a 4.5 gal ariston electric water heater, and a Laing circ with a built in thermostat for about 400sf of RFH . Between the differential on the water heater, and the differential on the thermostat for the circ 'twas not the best control, but temporary.

    Battled air also., and the aqua stat on the water heater would run wild sometimes.

    Electricity was killer on the wallet.

    Electric Towel Warmer:

    Nice install, bad idea.

    As far as electric towel warmers, that's what GFCI's are for.

    There should be GFCI's in the bathroom. If you take a power cord, plugged into a GFCI protected outlet, get into the tub full of water, and stick the live end of the cord into the water, the circuit will trip before the electricity can "get" you.
    Too bad that someone who should have known what's up, didn't know.
    Expensive.

    If that water heater...

    ... has an anode in it, there will be gas formed and there doesn't seem to be a way for it to escape.  I'd agree with venting at a point where the gas collects.... unless the "quadrature gravity" is at work. :~o

    I agree...

    I agree with Chris on the electric. I put in the electric version of
    that exact warmer. They literally screwed the element in where the
    piping threads in and filled the thing most of the way with water (a
    little air for expansion).It was right next to a shower with the timer installed across the room.  It worked great. Some people fear electricity
    and there is no talking them out of it. Personally, I fear all that extra stuff in cabinet waiting to spring a leak and flood my house.
    Larry,
    I had not thought of the anode. An air vent is a good call,
    Carl
