We bought our NAC40 in the summer of 2010. The boiler has worked without any issues ever since. We really like the simplicity of it, how well its build and it has been very reliable. We also save about 70% of our heating cost even with today's low gas prices. I would definitely recommend this boiler anyone who is looking to switch to burn coal.
