@ November 3, 2013 2:22 PM in code man says my DHW tank has to go as a heat source What now?Seriously!
Brian your research should lead you to the wall tankless WH are not boilers. Use the right tool for the job. Enough said.
Look closely at the warranty for closed loop heating , and that should be enough to note they are not designed for that purpose.
The taco xblock would work IF he ditched the tankless, and converted the tank style WH for domestic use.
Now the xblock is expensive, and I believe the tank WH is a little short on output. Using a HX will make it come up even more short on output due to efficiency loss of the xblock.
@ November 3, 2013 11:33 AM in Rinnai RC80HPIOf emitters besides RFH would operate at a 115 supply, and 73 return?
Possibly fan coils?
@ November 3, 2013 9:58 AM in Rinnai RC80HPIThere is no coverage when used in a closed loop heating system.
That should be a red flag in itself.
Also don't be fooled by the rated maximum output. It's a whole different game when used for space heating. Their outputs are based on high deltas not found in hot water heating systems.
@ November 2, 2013 6:05 PM in Knight boiler problemsDid you test the material to see if it is magnetic?
Did you personally witness the yearly cleanings
I think you had fouled intake air. Or some pretty fouled gas mixture.
@ November 2, 2013 5:35 PM in code man says my DHW tank has to go as a heat source What now?Sorry to hear that. Price other brands see what you get.
@ November 1, 2013 6:16 PM in HydroMXFrom what information that y you provided they are hanging their hat on heat transfer first. Non fouling to the system second. What if it does create issues a refund on the potion ?
What lab tests were done strictly heat transfer? What time frame was observed with no system issues?
What types of piping? Types of hydronic systems?
I'm share the same thoughts, and right now I see radiator stop leak in a nano form.
People here nano technology, and think it is high tech.
Think about HX fouling. Bad Water deposits alone can create havoc.
@ November 1, 2013 7:13 AM in HydroMXIs what happens to the suspended nano particles when the system is idle? Especially over the non heating/cooling time frames.
@ November 1, 2013 5:57 AM in Looking for alternatives to heating my old, large houseA pellet burner is cheaper than fuel oil.
Insert foot in mouth.
But I will say that fuel type has gone up a lot from its infancy.
@ October 31, 2013 9:06 PM in Looking for alternatives to heating my old, large houseBill
Its the supply and demand thing of course.
But I remember when pellet, and corn burners first came out the fuels were cheap compared to other energy sources NG LP OIL etc. Then those pellet burners took off, and so did the corn, and pellet prices to where NG is cheaper than burning pellets. Corn has other factors I understand. Who would a thoght a guy could make a killing in saw dust..
My buddy bought a pellet BBQ 1K quite nice to cook on, but the assorted wood species pellets are not cheap.
@ October 31, 2013 6:20 PM in HydroMXIn theory it makes sense.
My gut opinion is if the container says shake well before using could mean a recipe in the long term for issues.
What happens if there is a dirt separator installed in the system?
Not knocking something I have no experience with, but suspended aluminum, or copper ( is there a choice) in a hydronics system seems like a future fouling agent to me.
@ October 31, 2013 6:05 PM in Looking for alternatives to heating my old, large houseAs he pointed out on the envelope.
The only way you can cut your heating bill if you leave the envelope
"as is" is by using a cheaper fuel NG. Usually.
Pay for proper sealing, and insulation once, and you will be much happier than revamping the whole heating system, and switching fuels. That is a short term solution NG will not be cheap forever.
After the envelope is fixed then visit a new heating system that is more efficient.
P.S the pellet suppliers ruined the whole attractiveness of the pellet stove market in my opinion.
@ October 31, 2013 5:53 PM in Taco Bumblebee Buzzes-Are you both running the bee?
Just wondering if both of you are using same setting, or have tried different modes, or constant speeds ?
@ October 31, 2013 5:47 PM in code man says my DHW tank has to go as a heat source What now?You could get through another Canadian winter.
Devote spring /summer to an installation at your leisurely pace. Time to squire products. Maybe monitor your present system a little closer record readings, and compare to new installation.
@ October 31, 2013 6:47 AM in Taco Bumblebee Buzzes-Is piping isolated from structure?
It does not take much to reverberate velocity noise, or circ noise.
@ October 31, 2013 5:25 AM in code man says my DHW tank has to go as a heat source What now?Synopsis is heat source in code violation, so no bulk propane hook up for you until resolved.
So Morpho I was going to ask what the pros/cons of doing nothing about your situation?
No out of pocket to rectify violation of heat source.
No final occupancy permit?
No bulk delivery of propane.
Fines imposed possibly?
Is there a time line inspector is enforcing?
@ October 30, 2013 5:33 AM in code man says my DHW tank has to go as a heat source What now?If his only choice is LP why not? Wood Looked pretty distant on the property.
Oil is going to be more than LP.
Dont over think it.
@ October 29, 2013 7:56 PM in code man says my DHW tank has to go as a heat source What now?Is pretty darn close in size by the time you figure the output it's 40k input.
Some kind of back up still is not a bad idea no matter the true heat source though.
Morpho I don't know your water quality, but initial fill of distiller water would be of benefit .
@ October 29, 2013 5:25 AM in code man says my DHW tank has to go as a heat source What now?That style boilers heat exchanger is mineral deposits from continuous makeup water.
@ October 28, 2013 10:52 PM in The Blessed Technology of Fracking . . .Just a advance in technology.
For how many years did oil companies throw away gasoline because it was to volatile, and they did not know what else to do with it.
If you look at history we actually have come a long way in our means in protecting the environment compared to many a decades if not centuries ago.
@ October 28, 2013 10:21 PM in The Blessed Technology of Fracking . . .Equals another superfund cleanup on us.
@ October 28, 2013 9:19 PM in Heat - thermostatThe other things I listed to check.
Are yo new to this home?
If not was there an issue before?
Is this a new thermostat location?
Remember this is the shoulder season so the home just gets a little bump from the heating system here and there.
@ October 28, 2013 8:51 PM in code man says my DHW tank has to go as a heat source What now?10* for radiant floors for the heating loop.(primary). 35 at the boiler loop (secondary). The higher the delta at the boiler the more efficiency gained.
10* gives more even floor temps. You could go higher if your willing to sacrifice some foot comfort.
I'm thinking you need primary secondary anyway. Your headloss for the flow rates needed to maintain a 15* delta at the floor( a little sacrifice in comfort under foot) would be borderline bumble bee material. To close to call. Maybe SWEI has a different opinion.
