Been dealing with you guys since 89 haven't had a easier more helpful through to deal with been a pleasure.
Dana N.
Love the boiler, only used 3 cords of wood all winter to heat 3,000 sqft

I just wanted to say thank you to the gentleman who took my call over the weekend. The advice was perfect and I am sure glad to have had the answers he provided. The oil burner is going strong, and I can't say enough good things about AHS. Almost 15 years and the boiler is working as well as new, and you even provide phone support on weekends to customers who bought from you a decade and a half ago. You are a wonderful company.
Daniel K.
They are excellent people to deal with. They are trustworthy. They treat you like family.

Still In love with my Coal Gun 130 for 12 years now. Still runs flawlessly. And now with home heating oil at $5.20/ gallon I really love it. Last 2 months have saved our household close to $1000 over the equivalent BTU's in oil. Add to that that the anthracite coal companies are cleaning up the errors of mining years ago makes me feel good about burning coal.

Best coal stoker uses a lot less coal than other coal stokers very little maintenance Way better than oil

HAD ENOUGH WOOD MADE FOR MY LAST FURNAS TO LAST A YEAR. WITH THIS ONE IM LOOKING AT NOT MAKING WOOD FOR NEXT 2. THIS THING IS CRAZY EFFICENT!

With some tweaking, my furnace is more efficient than anything on the market.

In the eight years I have been taking care of our B-500 Boiler, it has required almost no maintenance.

I’ve had the boiler in use for several years now and I absolutely love it. There has been no issues, each year it performs flawlessly. The savings on heating bills has paid for the boiler unit many times over now.

I love the e140 and have been using it for almost 15 years.

I would like to thank Alternate Heating for the coal gun S130. Since installation the unit has worked flawlessly. It is the most efficient and clean source of heat I have ever ran in my home. I would recommend it to anyone, if your hesitant on pulling the trigger on this purchase don’t be. It’s the best decision I have ever made.
Frank Y.
If you’re going to burn wood I don’t know a better way to do it…

I have been enjoying my boiler since 2006 and recommend your products to anyone in can.
Jadrien O.
Got the part I needed in time to run my old MK3 coal stove for the winter, nicely made piece of steel, also got a second ash pan years ago and I was impressed with the construction and quality then too.
James F.
Furnace Has maintained Set Temperature on even the coldest days. If anything it is difficult to keep heat down in building on warmer days. Plan to install a dump zone in the spring to hopefully alleviate that problem.
Jeffrey T.
I bought an older boiler nearby and configured it with a 1500-gallon pressure vessel. Caleb was very helpful working with me to optimize the control logic.
John D.
Just want to say what a great product you make. I purchased an s260 back in May of 2014, and just got it installed... and runs like a champ. You make an awesome product, thank you.
John K.
Caleb is knowledgeable and awesome to work with. Thank You for your professionalism and assistance!
John S.
Its overall a great unit. Caleb with product support went above an beyond and helped trouble shoot a simple factory defect in the system wiring outside normal business hours. Great support means a lot.......very satisfied.. I have a few friends interested in these units as well
John Sh.
I have the E100 Woodgun. It was installed in 2013 and has been in operation every winter since. I am not an HVAC professional, but have been able to perform all of the required maintenance (routine and parts replacement) myself. This has saved hundreds of dollars and is a testament to the simplicity of the system.
Jon P.
Best equipment I have ever used. It been running like a clock since 2009. Every winter. ,, nothing better than AHS
Joseph G.
The owners are compassionate people. 100% focus is on the customer. I highly recommend Alternate Heating Systems.
Justin S.
Very happy with my E250 wood gun. I'm heating 10,000sq ft plus a spray booth air make up. Very well built and you have great customer service and parts when needed. Thanks
Kevin B.
I have run the boiler for around 11 years. very satisfied with your product.

Wonderful company to work with, Very responsive to answering questions. First time start up was my only nervous moment, but, very easy now after two fall start ups. Great product the 250, keep up the high quality standards .
Mark H.
Love it, use it for all house heating needs here in Vermont. Burns much less wood than other heating plants. good job!
Mark N.
We've been your customers for nearly 2 decades, and have always been extremely happy in all our dealings with you. i don't always answer this sort of survey, but felt that you folks earned our positive feedback. Thanks!
Ned P.
My E180 is 20 or more years old running 24hours 7 days a week heating my house, garage, and domestic water. You would have to be a die hard liberal to think you could have done a better job than you did! Great boiler!
Randy L.
I am amazed at how the boiler works. I originally was looking at a storage type system and am so glad the I listened to your engineers and installed just the boiler. I works perfectly. Thanks
Robert C.
Great company to deal with even a year after purchase. Prompt knowledgeable support.
Robert S.
it works great and saves us money
Roger M.
, My Coal Gun has been completely flawless! Burning coal is a little dirty with the dust but the boiler itself has performed admirably for (I think) 8 years now. The side affect of the dump zone in the basement has meant a warm basement and a garage that stays 60 degrees all winter with no other heat! The Coal Gun has been awesome!!
Ronald C.
U people were very professional
Ronald P.
Great product, great company, technical support is very responsive to questions with straight forward well informed and helpful responses. I highly recommend the Legacy Mark III stoves.
Russel H.
great unit would recommend to anybody looking to try something super easy to heat with
Scott B.
My E-155SS is a kick butt machine. Very minor upkeep with wearable parts once in a while, it purrs like a kitten. Have any coupons? I’ll need to replace my entire refractory in the next 2 years. I’ve pumped 52 cords through it in 6 seasons. Has saved me about $3,000 a year in oil and has long since paid itself off 👍🏼
Shawn D.
Over all it is a great boiler works awesome for my shop.
Todd L.
Very impressed. I have burned Wyoming coal in my boiler and saved a lot of money in heating cost.
Todd S.
My days of getting up in the middle of the night are over, thanks to the E-140 Woodgun boiler! My expectations for this boiler have been surpassed at every level. It is easy to operate, easy to clean and easy on wood. My only regret is that I didn't buy one sooner.

I found the adjustment, maintenance and cleaning of the Coal Gun boiler to be easy for a mechanically-minded, do-it-yourselfer.
