Overview of the Liberty
The Slant/Fin Liberty is a discontinued oil-fired cast iron boiler with an efficiency rating of up to 86% AFUE. The Liberty was available as either a hot water or steam boiler. It was equipped with a Beckett oil burner and featured a dual-size viewing port and convenient metal push nipples. These push nipples were located to the side of the heating sections, allowing a more uniform heat transfer while minimizing draft loss. All controls came wired and fully mounted, and steam models included float type or electronic low water cut-off.
Slant/Fin also produced a Liberty II boiler. The Liberty II is also discontinued and was the exact same boiler as the Liberty except for the front door panel, which had different hinges.

"Slate/Fin Liberty Boiler, inexpensive and great."
I have owned my Slant/Fin boiler for two years. What I love about my boiler is that it cut my energy costs by a lot and has kept me and my family warm throughout the cold winters. I have nothing negative to say about my Slant/Fin boiler. I would definitely recommend this boiler to any family members and friends, I have already gotten a few people to purchase the same model and they love it.

"Great Boiler for the price"
So far, we are very satisfied with our boiler. It was easy to install. Our fuel bill has dropped a good bit. It is very quiet and keeps us warm. Highly recommended.

"An Excellent Boiler for an Affordable Price!"
My boiler before this one was old and completely unreliable. Sometimes it would heat the water, other times, not at all. Sometimes, all I got was some lukewarm water. I had simply had enough. However, I am clueless about boilers, as I have never purchased one before. A friend of mine recommended I purchase this Liberty boiler. I have owned this boiler for over two years now, and couldn't be more satisfied. Installation was quick and simple, and before I knew it, I actually had a boiler that works properly, unlike the piece of junk before it. I like the fact that I am now never without hot water. The boiler runs on heating oil, and according to the manufacturer, has an annual fuel utilization efficiency rating of 86%. The boiler is efficient and reliable. What more could I ask for? The price is reasonable as well. I have never had a problem with it, and would highly recommend it to anyone.

"Adequate and nothing more."
I have had this boiler for about a year now and it has performed exactly as it should. It never really wowed me in terms of efficiency or how fast it could heat up, but it worked fine nonetheless. I like that is reliable and has worked every time I have turned it on so far. I dislike it because I thought for $2,000 it would work better, but I guess that money went to reliability instead of features. I haven't had to do any repairs on this unit at all. I would recommend this boiler to anyone.

"Oil water boiler review"
I have owned my boiler for about 3 years now. Very simple and sturdy set up. I don't like the noise it produces, but it can be overlooked. I have not needed to repair or replace any parts of my boiler yet. I do recommend this boiler to those that ask about one.

"My LD-30PT is really nice"
I got this from a plumber who had it sitting in the shop for about $1500. Almost too hot lol. I should turn it down. At any rate it had never been installed anywhere yet, and looked pretty good when he put it in. It's quieter than my old one. That one used to scare the cat when it turned on sometimes. However, my cat is crazy. Also saving quite a bit over the old one too. My LD-30PT. It smells a little strange when it's been on for a bit, but I figure that's just the newness of it. On the whole I'm glad my old one broke in March. The plumber said it should last 20 years.

"I'm just amazed!"
For as long as I have owned a home, I have had a wish list of sorts for certain things I have wanted to upgrade, and this has been planned for many years. Last year was the water heater, this year was the furnace. The upfront cost of it is a bit shocking, but when your furnace is on its last leg, it takes the sting away from the price tag a little. It is relatively small, runs reasonably quiet and after a couple months of use, my heating bill has gone down, so I am now seeing a payoff! It easily handles my 2,500 square foot home, including the half basement with relative ease. Home Depot installed it is about 3 hours and the best part, if needed, I can do the maintenance and seasonal cleaning myself on this thing and all the components seem sturdy. I'm completely satisfied thus far.

"Very Satisfied Owner"
I have owned my Liberty Oil Slantfin boiler for 2 years and have never had any problems with it. I like that it is energy-efficient and made out of cast-iron, which saves me money in energy and repairs in the long run. I have never had to repair this boiler. One thing I do dislike about my boiler is that it is not quite as quiet as advertised, as I can hear it as I lay in my bed at night. Overall, I would buy a Liberty Oil boiler again and again!
