The 110k figure for the LL boiler is the gross input?? It is less than I am used to dealing with when it comes to boilers, but it might be fine for your needs.

May be a light load...but not light on the pocket

I guess that depends on your point of reference.

Fuel was $3 per gallon when I "quit". It is $3.80 here right now, and I am sure glad the fuel truck doesn't stop at our place any longer.

Back to the heat load - didn't you recently measure the radiators in your house? What was the total length?

In my home 120 feet.

What I am paying for heating oil right now is $3.49. It is much higher than that, but we switched oil companies, and they locked us in at 3.49, I think it is in the high 3.60s normally.

I agree the other WL110K users I haven't gone thru cold weather yet (on line 10/23) but I feel it will do the job well based on my experience to date with my old HS Tarm 202 hand fed boiler. I'm heating 1900 Sq's in South East PA.

My DHW heater is just a well insulated storage tank that gets recharged from time to time via the WL110K 5GPM coil.

I am going to do a heat loss calculation on my house today, that will determine if the 110 will be sufficient, I have no doubts it don't be sufficient.

So for the heat loss calculation I came up with about 30k btu/hr heat loss. Based on the measurements, I actually only have 1576 sq ft of heated space. I was going off the numbers they gave me when I bought the house 1200 sq ft up stairs, 900 down. I have no doubts now that the 110 will provide more than enough heat for my house.

My heat loss came in at 28k

What did you set the inside temp and outside temp as, I did one for inside temp 72 and outside 30 and the other outside temp 15 at 15 degrees outside the heat loss is still only half of what the 110k should be able to put out, even at 80% efficiency.

The 110k should have no problem keeping up with my house heat and dhw.

My heat loss came in at 32k after re-working some numbers

Even at 0 Degrees outside, which doesn't happen to often around here, I could keep it at 76 degrees and its still be plenty okay.

We see lot of 0 degree days and many -10 days as well....but I think the LL110 would keep up with my needs just fine!

I live in south central pa and the coldest days I remember are like 10-15 degrees in the mornings.

My heat loss came up to 42k when I did the calc. and when the hvac people did it, it came to 37k. I have 130' equivalent of standard baseboard and I have no issues with the boiler keeping up. Based on the oil boiler size I would say it will work just fine.

What kind of coal usage am I looking at with the boiler, I heard that boilers will use more coal than a normal stove.
