Excellent Point Ironman

@ February 10, 2014 7:39 PM in Logamatic 2107 or Tekmar 260 ?

The Logamatic is not a cold start control, but can be more economical.

Aquastat

You don't need an aquastat if you use a Logamatic.

Fuel Usage

@ January 23, 2014 12:03 PM in Time Meter for Riello F5 Burner

June 4, 2013: "Underfiring does nothing but increase fuel usage."

Maybe that has been his experience and is that conclusion with or without ODR?
My findings in my situation suggest that blanket statement as incorrect.

I do it because my boiler is oversized, but not by choice it's the smallest model they make.
The heatloss for my home is under 40,000. I'm only driving 80 feet of baseboard.

The combustion numbers are much better when you fire the appliance with the correct nozzle.

Uses Less Oil

@ January 23, 2014 7:32 AM in Time Meter for Riello F5 Burner

When you lower the stack temp you increase the efficiency of the appliance. Lowering the firing rate does also stretch out the run times.

The downside is now the flame is too small and can get unstable at times. You can also end up with high rates of CO, sometimes not the best thing to do.

I can get away with it because I have a very short chimney that is lined. Low stack temps can really cause a lot of condensation inside a chimney, for that matter so does short cycling.

Firing Rate

@ January 21, 2014 7:28 PM in Time Meter for Riello F5 Burner

.55 IS the firing rate, I'm using a .4 nozzle.

with a .5 nozzle the firing rate still runs around .6

Properly Sized Boilers

@ January 21, 2014 5:36 PM in Time Meter for Riello F5 Burner

6000 x .55 x $3.00 / 6.2 years = $1597 per year.

Just goes to show what a properly sized boiler running ODR can do.

I'm A Residential

@ January 20, 2014 7:58 PM in Boiler Correct Size

guy, most homes we do range between 1500 and 3000 sq. ft.. We usually pull out an old oversized clunker and install the smallest oil boiler we can get our hands on. Our customers report a savings of around 25 to 30 percent usually, sometimes more.

I Don't Think

@ January 20, 2014 6:58 PM in Boiler Correct Size

I ever installed a boiler that large ever.


The OP is located on Long Island I seriously doubt his heat loss is above 50,000 BTU/ HR on a design day.

B2 is the Neutral

@ January 20, 2014 5:15 PM in Time Meter for Riello F5 Burner

B1 is the hot that fires the burner. Any neutral will work.


5,995 hours on the timer in my Logamatic

@ January 20, 2014 4:42 PM in Time Meter for Riello F5 Burner

That's just one of the neat features of the Logamatic, a time counter.

Wire the counter off of B1 in the Hydrostat.

Thanks for backing me up Chris! You can email me too!

2107

@ January 7, 2014 10:47 PM in Help with Buderus Logamatic 2107

I would just replace the factory sensor with one from Buderus, it really makes the most sense.

To get the hours run function to work requires a small amount of rewiring at the control.

Thanks for the Work

Professor, but your missing the money shot.

It

@ December 21, 2013 11:23 PM in Vitodens W2BA Installation Help (air intake)

don't use the adapter

2" PVC

@ December 21, 2013 7:10 PM in Vitodens W2BA Installation Help (air intake)

will go right into either intake port.

It's OK

Gordy, a perfectly soldered joint is certainly more beautiful than a propress one, no doubt about it. My problem is the time to make it beautiful. But, hey we're all different that's what makes this world go around.

Towel Warmer

@ December 10, 2013 9:07 PM in Runtal and Raditors piped together

I have a Buderus NB, the tappings are 1/2". it's piped in 1/2" off of a 3/4" baseboard loop with a 1/2" bypass (no monoflo tee's). The supply piping is below the towel bar, it heats perfectly. Everybody should have a towel warmer in their bathroom!

FYI the mounting hardware is plastic.

has said water, no problem. Once we changed a valve out on the fly, we couldn't find the main.
