Snowmelt

@ July 17, 2009 6:16 AM in snow melt slab temps

Here in Eastern Iowa I design for 28 degrees idle and 36 - 38 degrees melting temps and have had no problems.

What angle?

@ June 22, 2009 5:49 PM in Best angle for unglazed solar pool heater

Is there an ideal angle to place an unglazed solar pool heater? I have some flexibility here. Thanks, Rich L

@ June 3, 2009 1:36 PM in Your personal heating system?

Biasi B10/3 Riello, SuperStor SS 40 gallon indirect, Honeywell AQ2000 Control, Wilo ECM Circs. 2100 Sqft uses about 500 gallons a year. This fall I'm adding a Mix panel for low temp radiant in the upstairs baths.

@ June 3, 2009 1:30 PM in Buderus won't run on generator

Did you check your AC frequency output??? This is one of the most common things I see when it comes to generators and electronics. The output frequecy of small generators seems to vary more than largesr counterparts as the flywheels have less kinetic energy to stabilize the output to the changing load and rley on the throttle govenor to adjust and maintain engine RPM which usually isn't quick enough to respond to a sudden load change.

@ May 29, 2009 5:09 PM in How many btu's does an INDIRECT hot water tank require...

Not going to preach, but I have a Super Stor SS40 40 gallon, and a very small oil boiler, Biasi B10-3. The heatloss on the house is 45k BTU at 10 deg outside, and we saw plenty of those days this winter and I had no issues running 2 showers in the morning, with night setback on the heat. I do run a mixing valve on the tank because my control post purges heat to the tank, so the tank temps do reach into the 140-145 range at times. I think unless you have a bunch of kids around, and the demamd is very high, there is no need to upsize the boiler for DHW production. Another option might be to upsize the tank a bit to provide enough for the peak demand assuming you are not overly concerned with recovery time. Some of the more advanced controls like mine have the ability to realize the priority call for DHW is going to long and its time to bring the heat circ back on.

@ April 21, 2009 3:48 PM in Radiant Heat PEX Bending

I wonder if your using pex-b or pex-a. Most of the pex-b I have come across is quite stiff, but pex-a (Mr.Pex is what I have used)in comparison is very easy to bend both with and against the coil.

I'm so sorry

@ April 11, 2009 2:44 PM in Happy White (Johnny's Mom) has passed. (Dan H.)

to hear of your loss Johnny. I've heard it said when our loved ones leave us their pain is passed on for those of us left behind. I've always found comfort knowing they're no longer bearing the worldly pains themselves. I'm sure your mothers in a better place and will always be smiling down upon you. God bless, Rich L

@ April 1, 2009 6:01 PM in Life Expectancy of boilers - oil vs. gas

forced hot water cast iron baseboard heaters mostly, but a couple of big old cast iron radiators.

True...

@ April 1, 2009 5:14 PM in Life Expectancy of boilers - oil vs. gas

I like that the Vitodens 200 has life time warranty on heat exchanger... it is where I am leaning because after rebates, tax credits it is a little over $12K. I like that we won't have to worry about it down the road. The Prestige is very alluring though. Not sure the Vitodens is worth the extra $5K. I am now, once again, feeling renewed vigor for the gas conversion.

answer to one question...

@ April 1, 2009 5:12 PM in Life Expectancy of boilers - oil vs. gas

We have an indirect water heater - only 5 years old or so, by Weil McLain - we can re-use. not sure what an emitter is... taking a guess here: is it what emits the heat? if so, we have cast iron baseboard heaters in most rooms, plus a couple of the old cast iron radiators (this is an 1890's victorian). We've added a lot of insulation, including iconene and have mostly replaced the windows with double pane.

gas vs. oil

@ April 1, 2009 2:09 PM in Life Expectancy of boilers - oil vs. gas

we are in Massachusetts. We used approximately 1700 gallons of oil last year at an average cost of $3.50 per gallon. This year we should use approximately 1500 gallons at an average of $3.00 per gallon. I called the gas company to get some help in figuring out our projected cost of gas - all they could do was direct me to their website to a calculator which doesn't seem very accurate - told me that my oil cost is $2200/year (in actuality it is more than double) and gas cost should be $1100 per year. Also, wanted to say that I finally got the price from the last contractor I was waiting on (which was my first choice in terms of my perceived quality of installation - this is the company my gut says to go with, although it took a very long time to get the quote and the salesperson was rather unresponsive to my inquiries of when I'd receive it -- tiny red flag which is unfortunate). Their pricing is (BEFORE rebates/tax credits) - have sent an inquiry to find out if pricing includes outdoor reset which wasn't mentioned in the quote:
  • Vitodens 200: $15,400
  • TT Prestige Solo 110: $10,400
  • life expectancy of boilers - oil vs. gas

    @ April 1, 2009 12:39 PM in Life Expectancy of boilers - oil vs. gas

    posting again for more help... Was initially set on converting to gas and going with mod/con with outdoor reset (already have gas in the house) and going with TT Prestige (waiting on price for Vitodens 200 but we are on a budget and I think that won't work). Also got pricing on Burnham Alpine. My oil company came to present to us this morning and really want to keep us - they've cut their profit to the bone and I was impressed with the amount of work that went into trying to keep us. With some of the equipement they suggested we'd have to line the chimney - it will cost us around $4K - that isn't something we want to do. We could go with the Viessmann Vitorond with direct vent and with Vitotronic 200 outdoor reset (combined equipment cost: $5350 and installation of $4390 / we also need a new oil tank so another $1600 - total to stay with oil: $11340. He also gave us a price for the Viessmann Vitola, but w/o the direct vent option for this equipment we are looking at having to use a Power Vent (they will use one by Field), which he said aren't the best option as motors fail, they are loud, and can puff out black smoke if burner isn't firing properly). If we went this route with outdoor reset we are looking at: $13800 If we went with gas conversion we are looking at $13,750 all in for the TT Prestige with outdoor reset (qualifies for $1500 Obama credit and $1000 gas credit). or another gas option: Burnham Alpine (subsidized equipment through gas company, so qualified for $1500 Obama money but no gas rebate). $9000 from one company all in $8400 from another all in. I am creating a spreadsheet to understand it all and wanted to plug in the life expectancy of the equipment. I understand the mod/con's don't last all that long as compared to cast iron oil fueled boilers. I think this is a variable to consider... if I have to buy two pieces of gas equipment (plus installation) then perhaps sticking with oil makes more sense than I originally thought. Sorry for sharing pricing but I think it is rather pertinent given that money is definitely an issue in making this decision. In Summary:
  • any idea on life expectancy of:
  • OIL OPTIONS
  • Vitola (AFUE: 87% - cost: $13,800)
  • Vitorond (AFUE: 86.9% - cost: $11,340)
  • GAS OPTIONS
  • TT Prestige (AFUE: 95% - cost after rebates: $11,250)
  • Vitodens 200 - don't have price yet
  • Burnham Alpine - (AFUE: 95% - cost: about $7,000 after tax credit) what would you do in my sitution. I have taken your advice and shopped the installer - the Burnham installers are through the gas company and I wasn't as impressed with them as the two other gas contractors or the oil company. THANK YOU!

    Another radiant rescue

    @ March 19, 2009 5:39 AM in Another rescue

    Started this project the other day. Told james to start removing the old system and this is what he saw. Will be starting from scratch on this one . Will be installing new mod/com and all new piping & repipe the bosch water heater . House is all radiant heat in gypcrete overpour with 9 therms. . has a 250000 btu heating plant and still can't keep house warm ,we did a heat loss & found boiler to be way over sized and piping was all wrong . Installing this buderus being pre assembled on site,i wish all basement's were this big we plan on doing swap out today .

    @ March 10, 2009 6:23 PM in This Old House

    If your talking about the Concord Barn Project, that was Steve Thomas first season which was 89-90. Actually it was not the first time you saw Radiant on TOH. They did radiant baseboard and PEX in the last season with Bob Vila on the Bed and Breakfast house, which oddly enough was the first job Tom Silva worked on, but not his first appearance on the show (a real fan of the show would know that Tom appeared the season before to show a recently renovated kitchen). The season before that was the 1700's farm house that was a total mess, and I think the homeowner ended up suing the show over the budget overruns. They did Radiant floor in that extension as well with plywood strips and plates. You have to give richard credit for exposing the newest technologies, such as mod-cons and radiant. And Yes, I watch too much TV, godd bless my Tivo.

    Whatever,,,they work

    @ March 4, 2009 1:30 AM in BELL & GOSSETT IN-LINE AIR SEPERATOR

    Six years ago I put in an IAS [18 inches before the circulator , about as much distance after the boiler outlet, to allow laminar flows] and also the air-trol at the expansion tank. Wow! What a difference. My tank stopped being an unwanted 30 gallon of hot water that rotted the foodstuffs in the kitchen shelves above it. The tank remains cool and the system water never exchanges with the tank water. The air remaining after fill purging just slowly disappears into the tank and the pump hums quietly. But, I swear it looked just like an empty fat wide spot in the line. I did not see two chambers. But, it works, well.

    And let me guess Dave...

    @ February 22, 2009 7:49 AM in Saturday Calls

    Either "your price is awfully high" or "We just want you to fix it, not re-pipe everything".

    Very Nice!

    @ February 8, 2009 12:53 PM in Solar Project - DF

    Very nice job Dan. Of course that's no surprise from you and your crews. I really like the schematic with the detailed sequence of operations, very professional. The outside pictures show a nice sunny day, should be some nice solar gain there. Do you have a means to dump excess heat in the summer months if necessary? I'm anxiously looking for oppertunities to enter the solar market in our area. I've been reading everything I can find and researching manufacturers. There's a lot of interesting equipment out there. Keep up the great work! Rich L.

    Electric rates

    @ February 8, 2009 9:27 AM in Ground Loop Heat Pump problems

    My 2-1/2 year old house, all GSHP system. No back-up resistance. My rates have averaged 10-1/2 cents/Kw. Average bill $137/ month. That's for all my electric, not just heating and cooling. I have the spread sheet if you'd like to see it. Back to your original question Wayne, there's no reason you couldn't install an extra loop in your system to increase efficiency. I think it would be a great way to go. BUT It's generally not done because it raises the cost of the project and most every job out there is a competitive bid. We try to sell the customer on the value but we all know $$$$. ME, I sincerely respect your knowledge in this industry but if you're loosing 50% of the compressors in the GSHP's your installing there's something wrong. Over the last 7 years we've done over 1000 tons of GSHP's for our local schools and have yet to loose one compressor. There's been a few boards and a reversing valve or two, but that's it so far. GSHP's have proven themselves to be a very reliable, cost efficient way to heat and cool homes and buildings in our area (Eastern Iowa, low temp in the last three weeks, under -30 degrees F).
