My old Buderis

JessVT

We have a 32 year old Buderis boiler for forced hot water heat and dhw. Recently the heat would not come on, so we did some testing and the circ wasn't getting power. That did not solve the issue, so we assumed it was the Logomatic 2017 as we had done troubleshooting on all other aspects. We were holding off to save up to fix it, 3 young kids, you know how it can be sometimes. Well, finally my hot water quit. Tried to take a shower, it was lukewarm. Checked the Buderis and it was not running at all. There was no signs of any leakage of water, no water coming from the overflowmor signs that any water had come from the overflow at all, it simply was not firing. I caved and called my oil company just for a diagnostic visit, I simply did not have time to mess with it. They come out and say the logomatic needs replacing, that is the problem. It would get a Resideo aquastat for a replacement. I know the change over is not as easy as swapping it out, but was hesitant to aloow them, seems no one in our area really knows our boiler. We have had several techs from various companies out over the years and we always end up having to fix things ourselves. They said if I let them come the next morning they would charge me LESS labor and just get it done. Rough estimate was $$$ in total, including the diagnostic. I said fine but all I have is $$$ to $$$$ to spend on this. Yup yup. So the guys come out and while installing they believed this pipe sticking out was where the aquastat should be placed and tried to remove it. After destroying said pipe, they had to cut the boiler jacket open, remove some foam, and discovered that it was welded in. Well I did a quick google search and found it was the way to attach to another water tank. Now they had to fix this pipe, they spent hours upon hours because they ruined the threads and bent it so badly. They had to cut off the end of it and machine pressed a cap on it. The cutting of the metal jacket sounded like a jack hammer and caused my whole house to vibrate. It was crazy. Well all is said and done and it had also needed a new expansion tank, it was full of water. No problem, 2 second job. Turn it on, set to go, oh its overflowing water like a river! It's overpressurizing. Long story short, the heat exchanger coil is now broken.

If it was not overflowing water before, could this broken coil have been caused by excessive force on an older boiler? Or is it likely that it was broken already? They want to charge me a much higher than quoted amount ($$$$ and then $$$$ when I complained I wouldn't pay for the labor of them screwing up and not knowing that the connector pipe was welded in and not where the aquastat was supposed to be installed) and I currently don't have heat or hot water yet. With heat, the pressure is still pretty high, and to run the dhw I have to swap wires to power it up and dump buckets of water or run a sump pump from the overflow since the coil is shot.

They installed a resideo aquastat, an expansion tank, a prv which we actually did not need but they assumed it was broken when it was actually the coil, and also flushed the boiler. However we dumped the 5 gallon buckets of water ourselves, running up and down the stairs and did ALL the grunt work for it while they managed the valve as we did.

Any information or where to start and what to do is greatly appreciated.

sure sounds like they were wrenching on something that was part of the tankless coil and broke the coil. other than the connections to the tankless coil, I can't really think of anything that isn't threaded in to the boiler block. Do you have a picture of what they were wrenching on?

If you can't afford a lawyer, call the local news channel. Someone came in and completely wrecked your heating system, and they want to charge you more to make it right? That's not how it works.

I'm curious what model Resideo they installed.

And sorry to twist the knife, but we're not allowed to discuss pricing.

And a good lawyer!

The well for the new Aquastat is the same one as where the sensors for the 2107 were.

What the did is totally incompetent.
