@ April 4, 2013 8:20 PM in Question on sizing flat plate heat exchangersSo I am designing a system for my home as a project for the system design class I am attending. My home is heated by a oil fired hot water boiler and baseboard. I could just design the ac side for this class but I’m thinking of also including a hot water coil which would eliminate the baseboard. I completed the Manual J for my home and it states that my heat loss is 65,400 Btu/hr.
My plan is to use a flat plate heat exchanger, the type of heat exchanger that the system 2000 uses to make domestic hot water using a plain electric water storage tank, to supply a 50/50 premix of glycol to the coil. My problem is that I am having trouble finding the Btu ratings of these devices. Also, the specific heat of glycol is .85. So I figure the flat coil would have to be rated at 75,000 btu/hr right?
@ March 26, 2013 11:39 AM in Air in Oil LineI would vac check the pump and oil line from the fitting closest to the tank. If you have no leak then your problem is outside. Otherwise find the leak. It could be a bad flair, pin leak in the line, a bad gasket on the top or bottom of your fuel filter, you may have to have the pump fittings redoped or replace the gasket. Check valves do not fix suction leaks, they just add vac to the line. Tigerloop is a good idea too. It is a nice way to create a small reservoir to heat the oil.
@ March 19, 2013 5:46 PM in Anyone else use this trio setup?That boiler sure does look a lot like the Biasi boiler I have down in my basement.
@ March 13, 2013 3:47 PM in Problems with new(er) Honey well spark controlif your neutral is good then you should get the same reading in your meter from hot to ground as you would get from hot to neutral. You can also check from hot to a grounded pipe and compare to the reading from hot to the ground.
@ February 17, 2013 5:12 AM in broken bleed valve on burnerWish you took a picture of the pump. But guessing from the view of the beckett style nozzle line in this picture, I'd guess that it was a 1725 a pump.
@ February 11, 2013 8:20 PM in Looking for a New BoilerIs a bad idea. I don't know where you got your number for BTUs and I don't know where you live. But if your numbers are right then those are the BTUs needed to maintain a home's temp on a 15 degree day here on Long Island. How many days do we get those low temps? For most of the heating season even the best sized boiler is oversized.
As far as what type of system is best, all I will suggest is a low mass three pass boiler which is oil fired. I prefer the Riello burner. LP is more expensive than oil and contains about 93,000 BTUs per gallon compared to oil's approximate 137.000 BTUs per gallon.
@ January 25, 2013 1:38 PM in ThermoPride OL5-85RB no flameDepending on how badly you have saturated the unit with oil, you may be looking at a very smoky start up to new equipment. If you do finally get it to light, you could be looking at a self-inflicted puff back. Sorry to say, but every time you hit that reset, you increase the cost of the inevitable service call.
@ January 15, 2013 4:08 PM in Burnham V-14A summer shutdownIt is not always a good idea to shut your boiler off for the summer but many people do. I would make sure that the boiler was cleaned very well before turning it off though. Because it will get pretty wet between the sections if it is in a basement. This will turn whatever is in the sections into mud. Turn it on in the fall and you could end up with a substance that is tougher than cement. Also keep an eye on the boiler when you first shut it off. Old flange gaskets tend to leak and could do some real damage to the area around the boiler.
My other concern is your choice of water heater. They are the cheapest to install and, by far, the most expensive to operate. If you have access to gas that would be the way to go. And I'm pretty sure that a gas water heater would be cheaper to run than an electric water heater. Plus you get a much better recovery rate from gas and oil. I have had electric water heaters in the past. When you run out of hot water you have a bit of a wait before you get it back.

@ January 8, 2013 12:06 PM in Upgrading Beckett AFGAll of these upgrades would be worth doing during a repair that required the part to be changed. But they wouldn't be cost effective to change otherwise.
@ December 16, 2012 4:24 PM in Need help with my Arco - ideal water boilerIf you just can not afford to replace the boiler then contact a reputable company to make this repair. You will still be wasting oil but your home will be safe.
If you can afford an upgrade than this is a blessing in disguise. You will be amazed on how much money you save on oil with the new equipment available today. Triple pass boilers, indirect water heaters, out door temperature reset and cold start technology is the way to go. BTW, get a heat loss calculation done. Your old boiler is most likely oversized for your home.
@ December 16, 2012 4:16 PM in Beckett AFG2 line oil lines are a thing of the past and will soon be the only reason for finding soot in a boiler now that NYS is burning low sulfur oil. With the better oil and a system set up using combustion tools, oil should burn as clean as gas.
But 2 pipe systems will continue to soot. This is because of the higher pump vac needed to pull the maximum gph of the pump. Another problem is that vac leaks in the supply line will not knock the burner off. So you will have fluctuating pump pressures and soot.
I would vac test the supply line. If there are no vac leaks then change to 1 pipe. If there are vac leaks then repair those leaks and 1 pipe. If you insist on having the pump 2 piped then have it 2 piped to a tiger loop. This will keep the vac down to just what is required to supply the gph of the nozzle. If you still have vac leaks in your line the tigerloop will not cover this problem up though.
@ December 8, 2012 4:38 AM in gas conversion, tankless coil not performingLooks like a real nice job. The money you save this winter should more than pay for a new water heater this spring. From there on you will just continue to save money and make the system more desirable when you do sell.
@ November 14, 2012 10:20 AM in Heat takes a long time to reach some radiators in a hot water systemYou say you have one cast iron radiator on each floor. What type of radiators are heating the rest of the house? What is the pressure on the boiler?
@ November 12, 2012 5:59 PM in LO limit not working?An L8041B is a dual aquastat. If you have it set at 180 and the low at 130 the boiler will maintain 180 degrees and the circulator will stop at 130 degrees. I would reccomend setting them at 180, 160 or 160, 140.
A triple acting thermostat would work the way you expect this one to work. It would maintain temperature at the lower setting until there was a call for heat from the thermostat.
@ October 29, 2012 4:00 PM in crown oil fired boiler to propane?Right now I'm in the process of googling corn kernel burners. Looks like the way to go ;-)
@ October 29, 2012 3:54 PM in Igniter questionFirst, they are much lighter, but you know that already. They consume less electricity. And when they fail, they fail. Although this may not sound good, it really is. Cuts down on missing a bad transformer on a not automatic call. As already mentioned, you do not want to maintain the spark through the whole cycle.
@ August 11, 2012 7:43 PM in Why use different nozzle?Worked for a company that only used w nozzles.
@ August 11, 2012 5:49 AM in Back to workI'm attending Suffolk County Community College. Have two semesters to go.
@ August 10, 2012 12:29 PM in Back to workI've been out of work for a while. But just answered an ad for a refrigeration tech at one of the local colleges. Interviewed at 8 am this morning and got a call around 10 am that I got the job. Looking forward to putting what I've been learning in the HVAC program at Suffolk to work!
