Hey I never said this was a fix all. I just think for right now with the cost of oil there is a slightly better way. I don't plan on ripping my indirect out of the boiler. Heck I'm the one that hooked it up in the first place. I have talked about this with quite a few people in the industry and everyone agrees that right now oil isn't the best choice. But there are some die hard people on here that think it's the only way. Personally if I had the money to buy my propane tank I would throw a Rinnai up on the wall and be done with it. That to me makes more sense than anything. But until I put up my addition I don't plan on burying a propane tank just yet.I will believe that the government is broke when the welfare checks start bouncing!!

What size indirect do you have.

Ah, a tankless coil.
They bite period.
I thought you had an indirect, my mistake.
I was going to say, that with an indirect, you can lower your boilers min water temp, and still have better frecovery then an electric, and not lose as much heat to the basement or up the chimney.
In the case of a tankless coil, electric water heater is almost always cheaper.
Nothing wrong with Slantfin though.

As far as slant fin. Yeach. If it wouldn't have been like a year old when I moved it I would have tore it out. I prefer a nice new yorker. This thing is crazy over sized for my house too. I just noticed now actually that you asked the question and I had to look at the rating. I did my heat load calc a few weeks ago to size my AC and this boiler is about 3 times bigger than what I need. Guess I'll have to down fire it a bit more than spec.I will believe that the government is broke when the welfare checks start bouncing!!

'Lectric cheaper to install for sure but an indirect will still beat and electric water heater for cost of operation, unless the electric is somewhere where the cost of a KW is less than a dime. How about a nice geothermal system with desuperheaters?If YOU want change, YOU have to first change.
If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!

When we say indirect.
We're refering to a tank that is hooked to the boiler, and uses the boiler to heat it.
Those tanks are insulated to the point that they only lose about 1/2*F and hour.
Which means if you go away for the weekend, It only has to run the boiler once about every 20 hours to maintain its temp.
You don't have to maintain as high of a water temp in the boiler.

propane isn't all that bad if u find the right price
91k btu at 92%=83720btu/gallon
just paid 2.22/gallon=26.52/million btu
oil at 3.25/gal with 83% eff=27.19/million btu
efficiency is key!!

Yes its a liberty and your right, it isn't that bad. I'm just not the biggest fan of sectional boilers. Never was. And the slant fin name always makes me think that they are sold at Home Depot so I donut give them alot of respect for doing that. It has done me well and like I said it was new when I got here so I can't complain. I never really realized how over sized it was unit tonight like I said because I just did my heat loss calc this past month. I'll down fire it for sure. Wouldn't be the first time I down fired an oil burner out of spec. I guess the good thing is that it should be more than big enough to handle my addition one day. Maybe even the garage too. lol. Who knows. One day when I put the propane tank in for my stove I may just switch over to gas furnaces to go with my heat pump. It would be worth it to me just to have one less oil burner to clean.I will believe that the government is broke when the welfare checks start bouncing!!

Got a couple indirects on cold fire boilers.
Don't 100% recomend it though.

Right now I'm installing an electric HWH and running it off of a relay so I can shut it down during the day.I will believe that the government is broke when the welfare checks start bouncing!!

Hot Water Heat pump ... incentives ?
(and time-of-day use electric rates, if appropriate )
to heat the hot water to save > 60% ( $150 / year) of the energy.
The relay will save ~ $10 per year.
... seems like the pay-back periods might be 2 to 6 years.
