I bought my Shaver 165 in 2010 and heated with it that year. I had leaky fittings from the factory right off the bat. I replaced them myself, so I didn't think it was that big of deal at this point in time. I had a good seller, very nice and helpful. The year I bought it he got cancer, so I didn't bother him with the problems. Then, in the 2011 heating season, the pump went out and the blower, too. Now I'm starting to become unhappy with it. So I replaced them and the rest of the season went okay. I started to notice the tremendous amount of wood I was using, and I only use hardwood. My house is 1400 square feet and insulated very well. I live in Kentucky, so I don't live where it gets below 20 a lot. I'm an HVAC tech, so I can fix most of the problems myself, but I'm still not happy. Then, in the 2012 heating season, the boiler got a leak in the front, about a inch above the door. So I repaired that. The pump went out again. So replaced it again. I should mention I called Shaver, with no help through all these problems. So I took it upon myself to fix them due to that fact that I have young children, one who is disabled. Then, in the 2013 heating season, another leak in the front, about 6 inches to the side of the door. I repaired that. So I removed all the tin around the outside of the boiler and the sides. The steel wasn't protected from rust with paint, so condensation was rusting it. So I sanded and painted it. Then, in the 2014 heating season, the pump was out again. I replaced it. I looked inside the boiler like I do every season, and I noticed the flue pipe, where it doesn't cover, is scaling and rusting away due to condensation and steam. Soon that will need to be replaced. Since I've bought this piece of **** Shaver has redone the design of the water jacket where the water drains out the top of the box. It's not like the older version, where it drains out the side of the boiler about 6 inches from the top, where the steam and condensation happens. This should be a recall, like with vehicles when they have a major problem or fix. The government should step in because this is a major problem with older Shavers from possibly 2012 and back. So the newer version the flue is completely covered in water, preventing the scale and rust as long as you keep the boiler full. They say now, when buying a boiler, that their chemical for the water lasts 5 years instead of having to put chemicals in it every month. It's because of that fix with the drain at the top. I do realize some have bad water that has to be treated all the time even with the fix. but the ones who have pretty good water don't, which does help the customers who bought older version because the flue pipe is going to rust out eventually. The steel they used to make these boilers is poor quality and the fittings are plastic; the pump is low end and the blower is a low end product. The grate inside will warp and spread; it won't fit right after awhile. Bottom line – it has very poor quality material and workmanship. There should be a major recall on the older boilers from 2012 and back to replace them because they didn't come up with a whole new designed boiler. For example, the 165 is exactly the same design, but with the drain fixed due to all the problems it was causing. So they fixed it for future buyers, but that does nothing for us. A recall should be forced by a judge or government. Stay away like the others say.
