Hot rods approach

@ May 12, 2014 6:15 PM in Shower

I like going vertical keeping the tube off the studs except at alternating tops, and bottoms. Saves routering slots, and only drilling holes for tubes. Unless heatloss needs closer centers than stud layout allows which you could throw a plate on both sides of a stud. Cement board screws bad day!

Muddled walls

@ May 8, 2014 10:12 PM in Shower

My showers were both muddled. I remodeled one if I had known how solid it was that's where I would have gone in a tornado. The only reason I remodeled it was I had to replace the shower valve.

Ventilation

@ May 7, 2014 6:25 AM in Shower

Forgot about that only because I just take for granted ventilation in a bath is done....and correctly.

Ceiling rad down side

@ May 6, 2014 8:40 PM in Ceiling Question

None I live with them. Floors add elegance in baths and tiled kitchens basements.

Phoenix

@ May 6, 2014 2:05 PM in How many BTUs to overcome......

I was watching a show not long ago on climate Change Phoenix avg temp has rose six degrees because all of the asphalt and ac compressors since it's big building boom. It would be cool to know the total btus wasted through man made wasted heat generated world wide.

Buffer location

@ May 6, 2014 1:36 PM in List of small mod/cons

Basically you could use the buffer like a hydraulic separator. So same location. IF you really think you need a buffer.

Savings

@ May 6, 2014 1:11 PM in List of small mod/cons

Ced 1/2 of your 40% is just the difference in using cheaper fuel lp vs oil. Gotta
Account for that plus using right size boiler.

If an installer walked in gave you an 85% properly sized ng ci boiler he would save you 30% look like a hero for 1/2 the cost of a mod con. This is what heatpro is trying to say previously.

Radiant ceilings

@ May 6, 2014 6:20 AM in Ceiling Question

Done all the time. A to often over looked radiant panel surface. I have them in my house love them.

But dual purpose is going to have issues. One is control between the lower floor room with ceiling radian, and the upper room which will end up having a mediocre radiant floor.

Depending on the loads of the two rooms which will unlikely be the same , and the radiant floor will not be as effective with tubing so far away from the floor assembly.

What you will end up with since one of the rooms will be a control slave to the other is one over heating, and one under heating which will depend on thermostat location.

So if the thermostat is in the radiant ceiling room the floor above will under heat.

If the thermostat is in the upper room the radiant ceiling room will over heat.

The only way to get effective control is to do staple up to the floor for above room. Insulate. Then do ceiling radiant assembly. Now you have two zone you can control separately.

Also ceiling radiant back losses are not that high to effectively heat a room above with back losses alone.

Happy birthday To Bill

Glad you two enjoyed the day.

Gypsum 120 degree limit

@ May 3, 2014 7:38 AM in Anyone???

Wonder if that's why the drywall disintegrated like that, and if that's where gyp manufacturers got their temp limit from.

Big house

@ May 3, 2014 7:20 AM in Heat Load assessment different from quuted Boiler Size

62k looks a little light unless there were a bunch of envelope upgrades. If there were any did the heating contractor know.
Where is your location?

What design temp are you using to calculate the heatloss?

What water temp are you using to determine btu output of rads?

He may be sizing the boiler to the connected load.

Happy Birthday

And many, many more Mark. Learned so much from you. Since day 1 on this site have always absorbed what you have to say..... Thanks!

Well said KC

@ May 2, 2014 6:46 PM in "Kitchen Boiler Connections" from 1899.

Indeed., but Just think of the unemployment rate alone if things were built to last 100 years . As soon as all buying consumers of said product were supplied companies would have to close shop. I think a little of that plays into it along with the engineering.


I do have to say though I'm tired of the complete junk in all aspects of products. There is designed to do the job, and designed to just do the job....a short while.

Condensing ceiling

@ May 2, 2014 1:30 PM in Shower

Hmm never seen that sounds like an insulation issue. Would happen regardless of radiant surface presence.

38k all day

@ May 2, 2014 7:06 AM in List of small mod/cons

No matter the outdoor temp.

What your design temp is plays a lot into this. Control strategy also etc ODR.

Example being mild consistent winter temps verses wild load swings through out the heating season.

Curt's hypothesis

@ May 2, 2014 6:32 AM in List of small mod/cons

Holds a lot of water. One has to look at system as a whole small zones verse single zoned systems. Micro zones can kill boiler efficiency.

heatpro the ability to modulate to the load means tons in savings verses the added condensing efficiency. It is also deeper than 85 verse 95 percent efficiency. A bang 100k btu fire no matter the load burns more than coming on line at 25k to match the load.

Peoples claims to saving, or the lack of has to be taken with a grain of salt. Most people just look at the bill with out realizing gas cost difference, or weather from year to year.

Big showers

@ May 2, 2014 6:19 AM in Shower

Can be fun designing. Think shower seat with a little radiant touch for the tosh , niches for bath products, and a foot niche for the ladies about 12-15" up to shave their legs. Lots of possibilities.

Radiant shower walls

@ May 1, 2014 5:58 AM in Shower

Along with the floor.....Cozy. You may not want to come out.

Scrapers

@ April 28, 2014 6:27 PM in Never seen this before

The new owner has no heating system now. I would say the scrapers took anything they could get with a sawzall.

Production

@ April 27, 2014 8:59 PM in Are you in the market for a Thermal Imager?

From a production stand point it's probably much cheaper to make them all with same components, and disable certain functions than to produce several different lines with differing functions, and components. Pretty smart really. Who wants the best options buys them with out even knowing their really all the same. I wonder how the cat got out of the bag.

Think of it this way most modcon boilers have two or three sizes where the HX is the same size but btu outputs differ what changes to make them different is really not much for the cost differences.

Surface area of stranded
