Re: Venting into a chimney
Consensus doesn’t matter. The fact is that you cannot vent a condensing boiler into a masonry or metal chimney.
The manufacturer’s installation instructions give detailed info on how the appliance must be vented and it’s mandatory that they be followed.

Re: New Refrigerants
There's nothing wrong with R764……
I would think adding 410A to a system tagged for R454B would be a violation, no? Even if it does work, now the next guy doesn't know what's in it.
How does adding two blended refrigerants together work out in the end?

Re: Automatic air bleed, but how?
Put a mini ball valve on it to make cleaning and change outs easy. I’ve only used Caleffi ones for the last 5 years. Better built/made and able to clean repair. The one you have pictured, to me, is a throw away item.
Re: EK System 2000 hot water suddenly too hot?
Good morning, All. Not much left to cover here as everyone seems to have hit the nail on the head. I've attached a sheet that may help with trouble shooting. I would confirm with a clamp on thermometer, if you can, those temperatures. Based on the IF unit your using and the patina of the pipe the readings can vary. You'll also want to check out the boiler side and look for a 35 ° drop there under the same conditions of a tank re-heating. If your temperatures are outside the 70° rise and 35 ° drop, confirm your smart pump 006 is operational. Confirm the check valve is holding. At this time i would replace the plate exchanger.
It appears that the thermostat is turning on and off, but really that's all it's supposed to do. It doesn't control the temperature per say just confirms when the tank is totally hot. I didn't see a mixing valve in the pictures, but installation of one will give you more consistent hot water outlet temperatures.
If you need a service provider in your area you can call our Territory manager Brian Kiernan 570-872-6997 or the factory 908-735-2066.

Re: EK System 2000 hot water suddenly too hot?
It is a good investment to have a listed thermostatic mixing valve on the tank. At least 4 States require a mixing valve on any DHW source.
An ASSE 1070 or dual listed 1017/1070 would limit the DHW to120 and fail cold.

Re: question on 608 test
i don't think you're supposed to have that, just temp and pressure, the rest you're supposed to know

Re: question on 608 test
there are questions about which refrigerant has a higher gwp or which is being phased out because of its gwp, but like all the different dates, you just need to know it or get enough of the easier ones right

Re: question on 608 test
it should just have pressure and temp, it is just for answering the questions about saturation points.

Re: Mini Split Location
Cassetts come with a condensate pump but I don't think it has much head capacity. Enough to get the condensate out of the cassette then you have to have gravity or another pump. I wouldn't use them unless you had a drop in ceiling so the tiles could be replaced if needed so they are not good for residential except for maybe a basement ceiling.
Re: New Venting for 135-Unit Apartment Buildings
Unless the returns have a vent path above the doorway they will form a trap and stop venting.
