Re: Replacing 17 year old oil fired boiler/need help
Has either of these folks done the basics? Step one. determine the actual heating demand of the structure. How many BTUh do you actually need in the coldest weather. Step two: measure the size of the radiators or baseboards in the house.
Step one will give you the size of boiler, in terms of BTUh, you actually need. It may not be as much as you think. Or as much as you have…
Step two will tell you what temperature the boiler needs to run at.
Until those two steps are done there's no point in trying to determine what boiler you might find useful…
Re: Water Heater cycle
Reseating the connector solved everything. I'm inclined to leave it alone for now. We'll see..

Re: Radiant Floor Heating System – Is a 10°F Single Space - Same Zone Temperature Difference Acceptable?
I really think the expert you need to talk to is a lawyer.
The fact that the builder and installer are acting this way makes me think they know there is something fundamentally wrong. If there were an easy fix they would have done it and moved on.
If the design or installation is fundamentally flawed, it could be that the only solution is to jackhammer out what's there and do it over. Depending on what the finishes are, that could be tens of thousands or even hundreds of thousands of dollars of work.
Once you start trying to fix it, you own the problem. I'll pass on some advice a lawyer once gave me. If you find yourself in a situation where it's looking like you're heading to litigation, think forward to the day when the trial is ending and both sides' lawyers are offering their summations, what do you want the facts to be? Because now is the time you can control what those facts are going to be. You want the jury to be hearing that you gave the contractors every opportunity to fix it, they stonewalled and only when you threatened to sue did they even try, and then they failed. You were the reasonable one, they were the unreasonable ones and the incompetent ones.
What you definitely don't want the jury hearing is that you went on the internet and did some research and changed a bunch of things and then the system didn't work.
Re: Mini Split Location
Don't put a 24000 in under any circumstances. You should be able to do 600 sq ft/ton12,000btu. What temperature are you expecting? If the 14,000 won't do it something is wrong unless you have no insulation.
Cathedral ceiling has little effect on the load as the space above your head stays unconditioned when on cooling. You really don't have a good spot to do this with one head. I would use 2 6000 btu or a 6 & an 8 if available. 2 tons for 600 square feet is crazy
Re: Mini Split Location
It's not ugly when it is quietly spewing cool air onto you that's for sure. The "Home" wall is not available he said.
Re: Question about lining 90 year old cast iron sewer pipe
I work for a commercial plumbing company. Our service department has been involved in these kinds of repairs, I do side sewers from time to time with invaded, collapsed or otherwise compromised pipe.
As much as you don't want to cut the concrete, that is where I would go with the inside portion. If the entire sawing operation is done wet you will not have dust anywhere. It requires a crew with wet vacs all the time, some dams to control the water. Done right it is an easy cleanup.
I'd start with the saw operation and remove the concrete and old pipe. Very carefully, expose where it leaves the house and have a lining or bursting contractor send in a sleeve straight down the pipe to the plastic side sewer, taking care of that clay section and far more easily than doing it in a deep pit. Been there done that.
Now you don't have all that weird work around those wyes under the concrete that you would have to cut up anyway. You can put in proper modern plumbing.

Re: What's a good humidity meter?
I've been using this for years. The only accuracy tests are comparing it to the display on dehumidifiers or humidistats I work on. Its always within a percentage or 2, so for the +/- range I need, to me its DOBA. I don't need wb or dew point often. It does take some time to acclimate when you first turn it on. About 5 minutes. After that it registers fairly quickly when taking supply and return readings or something.

Re: Furnace fan will not work
Can you turn the fan by hand? If the fan or motor are bad, that will happen — it will hum for a while then burn out the transformer.
Re: Near boiler piping/replacement boiler
A heat load would add some more info to the question. 1800 sq ft X 25 btu/ ft guesstimate= 45,000BTU/hr required. That is on the coldest day.
80% of the heating season the load could be in the 30,000 range. So the boiler 152,000 you have could be 3-4 maybe 5 times what you need.
While` not hydronically ideal for that boiler, the circs are not causing efficiency issues on the return, unless the system has noisy air issues?
Here is a simple buffer piping, direct to load method. Indirect on priority with its own circ.
