@ April 22, 2014 9:28 PM in Rinnai TGWH questions.Thinking of switching to installing Rinnai TGWH. The contractors that are installing these units are they good units and do they deliver the GPM that the manufacture claims these units will deliver what is their reialibility? What do you pay for these units models RL94i 199,000 BTU INPUT & RL75i 180,000 BTU INPUT models? What is installed price. You can email me at firstname.lastname@example.org thanks .

@ March 22, 2014 4:31 PM in Gas pipingTim please let us know what answer Navien comes up with.
You will spend a little more for the Prestige Solo PS110 boiler but that SS fire tube heat exchanger is a great design. The cost of the Smart SS indirect is going to be the same with either boiler. If you are switching from oil to nat gas there should be a big savings in the cost to heat your house so buy the boiler with the better heat exchanger. You will be glad you did!
@ March 12, 2014 6:52 PM in Sizing old cast iron water radiators that frozeThat is what I asked him for the number of sections for each radiator. He told me another wholesaler with the same info figured out the BTU for each radiator. I guess that other wholesaler is better than me and my technical people. Maybe if that wholesaler sold the old radiators they would never have frozen and broke in the first place and they would have been shipped with special water.
@ March 12, 2014 6:02 PM in Sizing old cast iron water radiators that frozeI have Dan's EDR book but he did not tell me how many sections so how am I supposed to figure it out?
@ March 12, 2014 4:50 PM in Sizing old cast iron water radiators that frozeI was given the following info from a heating contractor asking me to size replacement cast iron water radiators from this info.
7'x32" wall hung cast iron rad
9'x32" wall hung
25"x17" 4 pass
8'x32" wall hung
24"x32"x10" 3 pass
32"x42"x10" 3 pass
32"x32"x10 3 pass
32x32x10 3 pass
28"x25"c7" 6 pass
32"x12"x10" 3 pass
32"x18"x10" 3 pass
32"x30"x10" 3 pass
Can anyone size from this info
I was always told you need the following info
Number of sections
Number of tubes or columns.
Water or steam system.
Am I correct?
@ March 8, 2014 8:00 PM in Sizing a boiler in Watertown, MAI was told Burnham has a zoning control coming out soon that I believe will work with their Alpine and their new condensing boiler coming out soon that will run zone valves or circulator pumps for each zone and you will be able to tell the control the BTU of each zone and the boiler will only fire at the right BTU for each zone calling for heat. I was told the boiler will be able to fire at only 1,000 BTU. This control is being made by Taco just for Burnham and the control will only work with a Burnham condensing gas boiler.
If anyone from Burnham can give us more info that would be great.
@ March 5, 2014 7:36 PM in Beating a dead horse.LIABILITY the Burnham Oil boilers were tested and certified for Oil only. Not oil / nat gas / LP gas. If you convert a Burnham oil boiler over to gas the warranty ends and you the contractor are taking on the liability if something should go wrong. If I was asked to put a gas burner gun on a oil boiler I would contact the boiler manufacture and ask them if they approve doing this and if so with what brand gas burner gun is approved. Also if this effects their warranty.
@ March 5, 2014 7:16 PM in TT PE110 longer run timesI have a Triangle Tube PE110 nat gas boiler in my house. 100 plus year house with cast iron radiators one zone. The boiler is piped P/S with a Grundfos alpha pump set on lowest speed for main zone second and third zone available for future zones. Boiler runs with the outdoor reset control. What is the best way to get the boiler to run longer with lowest possible firing rate when there is a call for heat? I believe the contractor never changed the outdoor reset control from factory settings. This is the fifth winter and with the very cold weather the CI radiators have never been hotter that this year because when it gets very cold outside the boiler is sending out higher water temp to heat the radiators. If the heating curve was set for sending out 160 Deg max water temp when coldest weather is outside would this make for longer run times at lower firing rates? Would this improve system efficiency?
@ March 5, 2014 11:07 AM in Honeywell air ventCan a Honeywell air vent if it goes bad can the vent actually suck air into the system instead of venting the air?
@ February 27, 2014 8:35 PM in pex sizeTake a look at using Viega fostapex tubing. It is a full diameter Pex tubing with aluminum for the oxygen barrier. This tubing will not grow in length and it will not droop when running 180deg hot water through it. Great tubing comes in 20' lengths or 150' rolls.
@ January 16, 2014 4:15 PM in How many BTU old radiator puts outHello I did purchase Dan's book on E. D. R. but I have a radiator that I did not see listed in his book.
I need to determine how many BTU this radiator will deliver at 180* F water.
The cast iron radiator said Columbia on one end.
Can anyone tell me about how many BTU this radiator will deliver?
Thanks for your help.
@ January 12, 2014 3:24 PM in Replace tankless coil with tankless coil or go indirect?I would go with the indirect water heater. I have been told by many oil companies that a boiler with a domestic coil uses about 200 to 250 gallons (1 tank of oil) per year to make domestic hot water. If using 250 gallons per year it would cost about $825 just to make hot water. Buy a indirect water heater with a lifetime warranty that way you can use it in the future if you need to replace the boiler.
@ January 12, 2014 2:41 PM in 80 gallon elect on night meter..? power vent gas ?Look at installing a A O Smith tankless gas water heater. Models ATI540H - ATI340H - ATI240H high efficiency condensing models. Only use gas when hot water is needed. Vents with PVC pipe and fittings. Warranty is 15 years heat exchanger and 5 year parts.
@ January 12, 2014 2:29 PM in New Hot Water HeaterAs brand of water heaters go A O Smith is just as good as Bradford White or any other water heater. If you replace your tank type water heater with another tank type water heater you should flush the tank every 6 to 12 months to get sediment out of the bottom of the water heater. Do you have hard water? If you do and you do not have a water softener the lime sediment will build up on the bottom of the tank and over time the lime sediment will increase in thickness causing you to use more energy to heat through the steel tank and then through the lime sediment causing higher energy bills and putting extra heat on the bottom of the tank that can make the tank leak and fail. Another thing you need to do with a tank type water heater every two years is take out the anode rod and look at it. If it is gone you need to install a new anode rod. This will extend the life of your tank type water heater. Take a look at using the A O Smith tankless gas water heaters. Look at their ATI540H or ATI340H or ATI240H they are all high efficiency condensing tankless gas water heaters. They only use energy when hot water is needed and they never run out of hot water. The tank type water heaters have a 6 or 10 year warranty and the tankless gas water heaters have a 15 year heat exchanger and 5 year parts warranty. If you are going to install a tankless gas water heater make sure your gas line is large enough to carry 160,000 to 199,000 BTU depending on what unit you go with.
@ January 12, 2014 2:01 PM in domestic water heat for radiant heatI have a customer that has installed many A O Smith tankless gas water heaters for doing the heating in homes and radiant. He uses the ATI540H model and a Burnham Alliance indirect water heater to get the domestic hot water. www.hotwater.com check out the tankless gas water heater.
@ January 4, 2014 10:11 PM in stick with recessed cast iron or tear out and go radiant?Why don't you look into using a LP gas condensing boiler. If you own the LP tank you can shop for best cost on LP gas.
Burnham makes the MPO-IQ oil boiler 87% AFUE you can do outdoor reset with this boiler.
Use their Alliance IDWH for domestic hot water.
@ December 24, 2013 1:59 PM in Design-build hot water washdownTake a look at the A O Smith ATI540H tankless gas water heater www.hotwater.com it is a high efficiency condensing TGWH with 10 year heat exchanger warranty on commercial jobs 15 years HE warranty on residential jobs 199,900 BTU input.
40* F incoming water temp 160* out going water temp 3.1 GMP
check it out.
@ November 23, 2013 2:56 PM in Condensing gas boiler you installJust checking what brand high efficiency condensing gas boiler that you install. Do you use Triangle Tube, Burnham, Weil McLain, Peerlees, Lochinvar, Navien, Baxi, Laars, Bosch, Slant Fin, or Utica or any other brand? What are the main reasons for using the brand that you install? How long have you been installing high efficiency condensing gas boilers? Are there any problems with these condensing gas boilers? What is the life expectancy of this type of boiler?
@ June 6, 2013 7:44 AM in Steam to hot water radiator conversion valvesHi thanks for the input. I am a P&H wholesaler salesman and I have a customer doing this steam to hot water conversion job. It is a church job. We will do a heat loss. He will be removing all old black steel piping and he does water test the old cast iron radiators and the radiators will be flushed out before water system is piped in. He will also be installing a dirt separator on the system. He is telling the church if they want to do this conversion and the old radiators end up leaking down the road he is nor responsible for that. The church is the one who wants to convert steam to water. Any other input is helpful.
@ June 5, 2013 7:37 AM in Steam to hot water radiator conversion valvesHi I have a steam boiler job that is being converted to a hot water boiler job. I know oventrop makes a valve for this type job. Does anyone else make one?
