I have been getting quotes to replace the big dual-fuel boiler that came with my house when I bought it. It's an Essex Thermodynamics and it was installed in 1981. It can't be efficient, right? We ran it on oil for the first two winters here because the wood side didn't seem to work. As I'm sure you all know, oil is rediculously expensive. We decided to get rid on it. Being a fairly new home owner faced with the huge cost to replace it, I decided to do a little research on Essex. I happened to come across the owner Manny Pacheco's number in an old post on Hearth.com. With nothing to lose I tried to call him. Manny answered the phone on my call and came over the very next day to look at her. Over the years the previous owners had stripped parts off of it, so it did need work to get the wood side going. But, for a very reasonable price Manny had my boiler up and running 100% wood which is going to save me thousands this winter. He took the time to explain how the gasification process works, something the others copied from Essex. I am so glad I didn't replace it. I'm actually looking forward to when it's cold enough to run full time (a first for me!). I highly recommend Essex for anyone in the market for a dual-fuel boiler. After you look at Tarm and Wood Gun, give Manny a call 978-870-6599. Tell him Damian sent you!
