@ August 9, 2013 12:33 AM in New here with a lot of crazy questions.If you use pressurized tanks you can heat the water to above boiling and your circulators and related piping do not need to be for open system use. In other words spend more on the tanks and spend less on the other parts. The tanks will last far longer then the circulators will.
@ August 9, 2013 12:29 AM in New here with a lot of crazy questions.If you have flat ceilings you need to make sure the heat emitters you use can drain. The use of standard design radiators will leave a lot of water in them after a couple heating cycles. The use of flared copper like Gerry used has the advantage of being able to withstand vacuum well. I seldom see ceiling mounted radiators that do not have draining issues as they were not made even state side to lay flat. The heat exchanger to make steam from water also needs to give room for the water to separate. a drying chamber would help on the outlet of the heat exchanger well insulated 6" pipe would work. You can use it as a manifold for your steam tubes. The wall thickness allows enough metal where you could drill and tap into the pipe for sizes 1/2" BPS or smaller. From what you described I would say read up on the fire tube system and use it for a model.
What are you planning to use for heat emitters?
@ August 9, 2013 12:13 AM in How is businesswhen asked " how's business?" these are my three favorite replies:
1- Down the drain!
2- It runs hot and cold.
3- Steaming along!
DO good work, keep a fair profit, stand behind your work, and enjoy your work!
If you are not making a profit at the price the other guys are working for and you have your costs under control then go fishing now, for you will be busy fixing their installations when it gets cold out.

@ August 9, 2013 12:04 AM in New here with a lot of crazy questions.I am saying it may not even be available to you due to efficiency regulations based on max fluid temperatures instead of total system energy use. I was not suggesting hanging radiators off your ceiling. In the radiant section there are several threads about radiant tubing embedded in the ceiling. I will find a link to the a post for you.
You can check my posts I am defiantly pro steam. as well as definitely pro steam.
I just think a plane ticket to install your system would be cost prohibitive for the project.
@ August 8, 2013 6:35 PM in Prevailing wage questionsMaybe the "over paid" are not over paid. Maybe the rest of us are underpaid? I am not union, but I know if it was not for unions we would not have weekends, 40 hour work weeks, an end to child labor, and we would be working for the same wages as those flipping burgers.
@ August 8, 2013 6:30 PM in New here with a lot of crazy questions.that is the reason he went state side.
@ August 8, 2013 1:35 PM in kill overheat with wood furnaceyou need a storage tank, 500 to 1000 gallons and the proper controls. The way you have it piped is not efficient or safe. You are risking over heating either boiler while it is firing as water is lazy and seldom does what it is not forced to do by either gravity or a pump.
@ August 8, 2013 1:32 PM in New here with a lot of crazy questions.you will be better off using water. Radiant panels with a good condensing boiler will work quite well. Steam is good for use is the infrastructure and support is there. I recommend sticking with what the local supply chain has for those days when you need a part now and can not wait for it to come in three days.
p.s. I was almost a Kiwi, my Da was torn between coming to the States or going to New Zealand. Since he is a Scot he went with the cheaper air fare ticket and he we are.

@ August 8, 2013 1:24 PM in Prevailing wage questionsI was speak to the trade in general not to you personally. The entity paying is required to have the wage rates in print on hand. The town hall of whatever town you are working in should have it on file too as the rates are the same for any project they have going too.
@ August 8, 2013 1:31 AM in Prevailing wage questionsThey are in place to make sure the man turning the wrench gets paid a decent wage. If one can not afford to pay their help the prevailing wage for your region you need to reevaluate what you are charging. We do both private, state, and federal work. I have found many people bidding and doing work that requires Davis Bacon either can not do basic math or are lying about what they are paying their workers. In Mass it is divided by county and the rates are available from who ever is handing out the checks for the work.
@ July 30, 2013 11:07 PM in Advice needed on replacement hot water tankwhy risk high pressure gas pressure when running a larger pipe will suffice?
@ July 30, 2013 10:54 PM in Adding second hydronic loop to systemwe are debating this like it is a whole house heating system. It is a hot water loop off a steam boiler. Steve I will be calling by Thursday to discuss when I can come by. It is 25 feet of baseboard.
@ July 25, 2013 12:16 PM in Adding second hydronic loop to systemChris do you think that the heat flow will be slower for the room air across the baseboard if the water is moving too fast? The air will take the heat the same speed off the baseboard no matter the flow rate. In fact if you look the heat output of baseboard is higher for 4 gpm then it is for 1 gpm. It is on the charts for any given heat emitter. Yes we will waste electricity going to the pump as we are moving more water then we need to to heat the room.
@ July 25, 2013 7:51 AM in "serviced every year"- We were speechless.........I mean it is not a big deal to change a gauge or to put the gauge in a spare port.
@ July 25, 2013 7:46 AM in Adding second hydronic loop to systempump into the mixing valve. As the water warms up the flow diverters more and more to short circuit around until it looses heat and diverters back to boiler. Just like on the manifolds that I get from Viega for radiant systems. The zone pumps will each do their own thing. Steve do not use a bull tee for the second zone. Simply tee it off the supply pipe. You can always just have me do the installation for you. If it does not work I will post what a bad job I did right here on the wall for all to see. Chris there is no boiler to protect as it is a heat exchanger the cold water will be hitting. I only cover MA from West Stockbridge to Provincetown.
@ July 24, 2013 9:55 PM in Adding second hydronic loop to systemand the circulator on the return from the radiant loops with the circulator pushing into the mixing valve.
@ July 24, 2013 9:52 PM in Adding second hydronic loop to systemHe is using the everhot as a heatexchanger. He has a high temp loop and a low temp loop. He is using a taco 007 to push the water from the steam boiler through the everhot. He is piping the hot water loops off the side that would be the domestic coil.
@ July 24, 2013 9:41 PM in Adding second hydronic loop to systemI do not see why your newest diagram would not work. I just would suggest changing the circulator for the steam side to a B&G 100 Bronze.
@ July 24, 2013 9:36 PM in Is a Chimney Liner necessary with a Gas Power Burner?If you look at the charts for chimney size it is smaller for forced draft for the same given btu rating of boiler.
