One room mini boiler

FCOH | Posted in Energy, Heating & Insulation on April 30, 2008 01:44am

Just got done installing a LAING electrical heater/circulating pump. 

What a phenomenal product!

They say its small enough to fit inside a 3 1/2″ wall cavity,  that would be tight, but a 5 1/2″ wall no problem.  This one fit inside the cap wall next to the stairs.  Completely silent when running.  All I have to do now is figure out a way to finish the outside of that wall and still have access to the system.

This unit is heating a 12′ x 14′ room. 

We used a Roth panel installation over the existing slab, total cost not including labor, under $2000!

This would be perfect for an addition where forced air would be tough to run. 

Unbelievable. 

More pics if anyone is interested

    Anyone know how to attach a pic so that it opens smaller?

      Anyone know how to attach a pic so that it opens smaller? 

      Do you have any photo software installed on your computer?  Something off the CD that came with the camera?  Or something that was part of the computer's original software package? 

      If so, open one of those programs and look for "resize" under the various headings, then click on 480X640 or whatever is close to that number.  Follow the succeeding instructions until complete.  It's pretty simple to do, once you've found "resize".

        Not too expensive, just under 2k for materials and you could figure about the same for installation.

          Do you have a link to a website? Do they make a 110 volt also?                            Mike

          1. FCOH | Apr 30, 2008 05:48am | #8

            Dont know how to add a link to a website but its LAINGINC.COM

            Not sure if they make a 110 but thats initially how I ran the wiring.  I wasnt working properly so I switched it to a 240 at the electrical panel, along with some other minor adjustments, and it works like a champ now.

            Couldn't be happier and it's not even in my house.

    What model # is it?  Electric?

    1. FCOH | Apr 30, 2008 05:22am | #5

      The model #I installed was EHR 2 KR.

      Yes, it is electric.  240v. 8 amps

      1. renosteinke | May 04, 2008 04:38pm | #12

        Just discussing this in theory ... if the unit received half the volts, it would only produce 1/4 the heat.Turning it around, our OP said he tried 120v with poor results - really wants me to suggest folks actually look at nameplates and follow instructions. No, he says, at 240v it 'works like a champ.' Well, it's now cranking out 4x the heat it did at 120v.

    Would be just the right size to put hydronic heat in two or so bath rooms as long as they are close to each other.

    Good morning sir.

    If its not too much trouble, I would love to see any additional pictures that you might have of this setup.

    Correct me if I'm wrong, but as I understand it, this is a self contained system? Heating the water as well as recirculating it?

    Thank you in advance.

    Cheers,

    T.

      Here are some more.

      laing1. is the finished system with 240v ran.  i took out the on/off switch and ran new 120 to the transformer.  Rerouting the overflow drain tube is all that is needed.

      laing3. shows the expansion tank under the steps

      laing 4 & 6 show tubes. Kind of a pain getting the tubes to snap down into the roth panel.  It took me and a helper 3 hrs to run all the tubes and hook them up.

      More expensive but faster when your not a plumber.  I especially like them attatched a female fitting because it allows the pipe to spin if you need to tighten the connection on the other end.

     Here's where that would be a problem..

     Anyplace that gets really cold.

       Water in the wall?  where the required insulation to keep the system from freezing up? 

      If the outside of that wall is 40 below and there is no insulation in that wall.. when the unit is off what's to keep the system from freezing solid?

        Plus an area that size with no insulation would be a real bear for heat loss especially considering the high heat from that unit..

     I can see mounting it on an inside wall. In that application I really think that might have merit given a history of reliablity and lack of maintinace.   I'll check back in 20 years..  <grin>

      When doing radiant, insulation is always the first concern addressed.
