towell warmer

Unless you are running the system temps up to 180 degrees and maintaining them there for a decent period of time, exercising pumps simply guarantees that the bacteria are being flushed back to the tank for further distribution from the no tell hotel named Towel Warmer Inn...and that their food resources are being propped up.

Pump exercise programs do not erradicate the bacteria in and of themselves. You must have HEAT, extremely HIGH HEAT in contact with the bacteria for a specific amount of time to kill off the bacteria.

    towel warmer installation

    I am installing a heating system that is all radiant floor heat using a Viessman Vitodens 200 boiler with a low-loss header and an automated 3-way mixing valve. This system also has or will have an indirect water heater. The 3 way-valve will have a primary variable speed(smart pump)pump. The zoning is accomplished through telestats on the remote manifolds. What are your thoughts andor suggestions on where to pipe in the towell warmers?

    how many, what size, and

    how often do you want to run them?

    If you like warm towels year 'round, hydronic ones may really short cycle your boiler in the summer months. Consider running them on the DHW recirc line, if you have one.

    OR after trying hydronic towel bars in my home I opted for an electric version at the shop. it is much easier to control, you can regulate heat output to the room with towel placement.

    I added a nice Grasslin digital timer to set back at night, and during the day time on weekends. I may add the Runtal control with temperature and setback built in.

    I'm thinking about changing my home one to electric also. they are much more manageable.

    Re: potable & towel bars

    As long as there Brass or stainless. When we are doing a job and Myson brass towel bars are specd, we always refer this to plumber to tie to recirc. Other good reason is the Myson fitting connections are awful to get a good seal on, let the plumber have that one. Tim

    Have not seen them made of Pure Brass! are you sure that they are not just brass Plated ?If so, how about a SS exchanger? and yes ,I use hemp like in the fatherland.

    I've Checked on some of the "Supplement to Myson Hydr.Towel warmer instructions" for :VR/1; WHO;ECO;Musette:Gavotte;Rhapsody;Cavatine;Interlude;Maestro. and i am getting mixed information: on the front page is states that : Installation of these steel bodied towel warmers on any open system will void the warranty,and cause premature failure. but then some pages into the instructions they explain how to hook it up to Domestic Hot water Connection. ???? Can anyone explain this?

    Not the steel, the brass only

    The steel would not be approved for Potable use. The classic is made of de-zinc solid brass. Whatever de-zinc is.

    Sorry but i cannot find The "Pure Brass" ones anywhere. only Brass Plated .Am i not looking at the right ones ? even if they are made of "Pure brass and or SS". How many do you recommend and how do you control the possible Growth of Legionella in the Rads?

    You must excercise them on regular basis on timer

    So stagnation does not take place. (look under classic unit specs)

    Excercise unit?

    Sure wish you could post the link that tells a guy to do that,, looking at Myson I can`t find it.

    Thanks Mark,

    that settles my curiosity about towel warmers on DHW recirc lines, it seems the best thing to do is install on the closed side,, or go electric as Bob suggested. Thanks again!

    Mark, reply

    Mark, I know that you contracted it so I understand your comment. What I am saying is that if you are running a standard water heater at let say not ideal temps per your concern, the towel bar will make it no less succeptible to bacteria as long as it is exercised daily. That is my take. Also I agree that higher temps are better for bacterial kill. With that said, he who lives in metropolitan areas with water treatment are much less likely to have a problem either way but still the running of stagnant loop is still necessary. Tim

    Disinfection

    At 140°F, Legionella bacteria die in 30 minutes. At 151°F, they die in 2 minutes. 156°F and above kills them almost instantly. I dont think immediate disinfection is necessary, and those high temperatures increase the heat loss of the water heater. 140°F seems sufficient to me.

    Electric towel warmers are the way to go.
