Water clean it

@ December 10, 2013 10:45 PM in Any good ideas how to clean this heat exchanger?

Pipe the vent off the back so you can open the top of the boiler and start it. Use a small sprayer and shoot water down the sections after the boiler is near temp. Dont flood it.
All that crap will steam off and go right up the chimney.

Dont do that

@ December 9, 2013 9:49 PM in trying to combine fireplace with heat pump

you would be building a bomb. Second, you would be losing heat faster than your making it. Fireplaces typically use 500 cfm of indoor air. The only heat you get from a fireplace is radiant when standing in front of it.
They do make fireplace inserts that have efficiency approaching 80%. Forget about making hot water with it. That would be your best bet.

Inverter question for Eugene

I have noticed that most if not all mini splits use a rotary compressor. Why is that?
Why not use a scroll?

Oil tank

@ December 7, 2013 9:28 AM in Used oil after vacuuming?

I have a 300 gal skid mount tank that I painted with epoxy and sits outside the shop. I put all my waste oil in there and when it fills up there are a number of guys who will come pump it out and give you 50 cents a gallon. It will take 5 years to fill it and I dont have to run around getting rid of small amounts of oil. Plus I get 150 bucks when its full.

Dont waste your time, this argument is old and the answer is obvious. You are correct.

I have been waiting

@ December 4, 2013 9:12 PM in Altherma

for the other manufacturers to release them. They all have them in the european market but not here. Fujitsu said they were going to release it here last year but it never happened.
I think part of the problem is most american systems are high temp and these units stop at 130.
Also they are really nothing more than a ductless unit with a plate exchanger and they are way out of bounds pricewise.

Just got a call this morning

@ December 4, 2013 8:53 PM in Navien ch 240

On one I put in a little over a year ago. Customer said it was working but making a noise.
Raised the stats and sure enough, when the unit hit high fire it was making a screeching noise, almost like a bearing getting ready to seize. When it kicked down to a lower firing rate the noise disappeared.
Called Navien and they were very helpful, we ran the entire gauntlet of test and procedures but to no avail, turning this thing on high fire produced this sound.
After about an hour maybe two, Navien gave me a number for a new unit.
No labor included, Im going to have to eat this one.It should be a fairly simple exchange though.
Have any of you had this problem?

on the top of the risers. Not that this is your problem but unlikely to be covered by boiler warranty if boiler snaps.

Two stoves

@ December 2, 2013 10:09 AM in want feedback piping WOOD boiler gas mod/con backup via reverse indirect BUFFER tank

Absolutely, wood stoves like boilers have a tendency to be over sized, then when it gets too hot you either open the windows or choke the fire, Two smaller stoves are better.
One for the shoulders and two for the design.
Another thing he needs to be clear about is Makeup air and chimney design. There are so many misconceptions about these two items. Google "outside air for woodstove"
It gets downright humorous. Unlike the modulating gas boiler, where you get a bunch of professionals arguing the finer points..Wood brings everyone that's ever lit a fire into the discussion.. Farmers, mother earth news people, wood zealots and the list goes on and on.
Outside air for combustion is a must...its all outside air but its much better for you to control it than let it find its own way in. Pipe it in stainless steel with a fireproof wall entrance, so if negative draw ever becomes a reality, it is no concern.

Chimney lined with stainless liner same size as vent adapter and insulate with vermiculite. The more insulation the easier your life will be.

The problem is

@ December 1, 2013 6:45 PM in want feedback piping WOOD boiler gas mod/con backup via reverse indirect BUFFER tank

using your 800 gallon buffer. 800 gallons of water x 8.33 gives us 6664 pounds of water that has to be raised in temp from room temperature to 85degrees just to start the heating process. Thats 15 degrees( if the room is 70 more if its in a cold basement) we need to raise this 6664 pounds of water, that requires in a perfect world 99,960BTUs.You can add another 50% to that for boiler loss and heat loss during heating the buffer. OK so we have now expended almost 150000 btus just to get our buffer hot enough to start heating. This is why I recommend a bypass on the buffer. So anyway lets say its night time and 50 degrees out and heat load is about 10,000 and hour. You have already burned enough fuel to heat for 15 hours just getting your buffer up to temp. I was lean on the buffer starting temp because your drawings show domestic prefeed going through the buffer which means your buffer tank is going to be starting out at 55 degrees( remember its well insulated so it will stay cold a long time) Now you need to bring that buffer tank up to 85 from 55... thats 30 degrees for 800 gallons of water. Wow do that math.
All he needs to do is add 10,000 BTUs an hour to his house.  These systems really start to border on ridiculous for homes with low heat loads.
If you have to have this system at least put in one modern wood stove in the home, it will give you much better control of your heat and use much less wood during those shoulder seasons.

You may want to consider

@ December 1, 2013 11:11 AM in want feedback piping WOOD boiler gas mod/con backup via reverse indirect BUFFER tank

Coming off the boiler with a direct loop to the heating system and then bleeding excess into the buffer tank. Then switch the loop back to the buffer tank when it comes up to temp. A relay and an aquastat could do this.
Your boiler is already twice the size you require on the coldest day of the year. Whats going to happen the rest of the year? You will have to load up the boiler with enough wood to bring the buffer up to a temp you can heat with. My home is about the same as yours..design loss is 36000 at 0. We are at the end of November and still havent seen anything below 25 at night and we have been seeing 45- 50 some of these days.
Last night I burned .....maybe 3- 12 inch split rounds in the wood stove and it is 79 degrees in here with sun shining in.  If it gets really cold where you are and stays that way for extended periods and your going to keep that fire going nonstop...go for it.
It has been my experience living in south east PA  using an outdoor wood boiler then a indoor wood gasification unit and now finally a new epa quadrafire woodstove that by far and away the woodstove was my best idea.
No matter how you get your wood, there is work and money involved and wood boilers just have to much loss when they are not wide open.
Also be prepared for that unit to damper down when your buffer tank is maxed, it will still blow the relief valve and you will hate cleaning that filthy thing.
Just my opinion based on my experience.
Good luck

@ November 24, 2013 9:27 PM in Condensing gas boiler you install

Prestige. I believe this is year number 10. The MCBA controls were good but the Trimax is great.. Out of 50 some boilers I have had almost zero trouble. That is very important for me since I am the one installing and servicing. I like my weekends off and I don't care for working late at night.
The boiler doesn't require pri-sec piping in 90 percent of installations. Tying into old gravity systems straight through the exchanger on low speed and outdoor reset is just a win win situation. The company and staff is first class.

Mark, I hope you

@ November 14, 2013 8:19 AM in Trouble wiring humidifier

connected to the boiler wiring at all. Keep it simple, like Slim said, use a current sensing relay or a sail switch in series with the humidifier circuit. Your just going to go from the R terminal on your transformer to the sail switch, then to your humidistat, to your humidifier then back to your C terminal. The sail switch will only allow current to pass if the blower is running. 

Where are you getting 24v

@ November 13, 2013 6:08 PM in Trouble wiring humidifier

off of the Triangle. The Trimax is DC and the older mcba controlled units don't allow for 24 vac access. There must be some external relay that turns on the fan after it comes up to temp. I doubt the boiler and fan start simultaneously.You can just supply your own 24 vac tranformer and break the 24 vac through the humidistat and then an air switch in series. You could also add a dpdt relay or maybe there is already one there that pulls in when the coil comes up to temp. If they are using a 120v klix on switch just use the line coming from the klix on to the fan and pull in a RIB relay or you can just use one of those aprilaire inductance relays, expensive but less time consuming.

Its not that bad

Proper vent placement

@ November 10, 2013 3:03 PM in Hydronic Replacement Boiler Sizing

is the key here. 105 to 110 is fine if the duct is sized properly and the vents are strategically located. 160 degree air can be just as uncomfortable if its blowing on you.
Well designed and I stress that,Well designed heat pump systems work at low temps and feel as good as any warm air job.

Interesting statement

@ November 10, 2013 2:40 PM in Hydronic Replacement Boiler Sizing

Why do you feel the coils would need 180 on anything less than a design day?

Sorry to hear that Mark, All I can say is if they are worth 300 bucks ...pay it.
The federal reserve is not happy with bitcoin, it threatens dollar hegemony. At the same time if you invested in bitcoin when it started you made quite a bundle.
If I had to guess, your part of a major false flag, perpetrated to rally people to back the government with whatever is necessary to eliminate Bitcoin.
