Sorry Carl

@ May 23, 2014 8:20 PM in Time to pull the trigger

For the misspell, and misread post. Understand.

Maybe I'm missing something but if your piping P/S , or using a low loss header you would need two SS circs. If you use a HX you would need one SS circ on the heating side and a Ci on the boiler side. If you pipe direct then one ss circ but with that boiler HX should be a fore mentioned piping I think ops flow right will be different than minimum boiler flow rate.

Lack of information

@ May 21, 2014 6:04 AM in Home Run vs. "Stacked" Home Run for 3 Storey Home

So how many rads on second floor?

Something to consider if you are using a local chase for your stacked manifolds. How many runs of pex, and supply return piping to each floor manifold. Piping size to deliver required btus to each floor for the manifolds. Piping size to deliver required btus to each rad.


@ May 20, 2014 7:59 PM in Home Run vs. "Stacked" Home Run for 3 Storey Home

+1 manifolds have thier placethats not one of them.

Edit: Sometimes we try to apply technology to everything we do. Not all bad, but dont forget the heritage behind inovation sometimes the old way is better, cheaper, and easier.


@ May 18, 2014 9:39 PM in What do you think of this product?

Agree with others there is probably people who will buy it as is. Exception in the US need F, and gallons.

I'm with HeatPro the app needs to be able to calculate costs, and the shower piece needs to be able to display that data. Do that, and I think you will have an exceptional winner.

Will it curb water use? With some maybe, but I think most women could care less so long as they get the shower they deserve. Low gpm shower heads are the key. Like HeatPro says sell a quality one with your product as a package deal.

Non o2 barrier tubing

@ May 15, 2014 11:19 PM in Time to pull the trigger

You need to isolate the tubing via a heat exchanger.......or use non ferrous components circulator etc. I'd use the HX keeps component costs down.

3/4" copper can carry 42000 btus so it's big enough.

Trapped air

@ May 13, 2014 6:10 AM in Shower

Should not be a concern with proper flow rates. Is this shower muddled or cement board?

Agree with Jamie

@ May 12, 2014 6:19 PM in R Value Of Soils-Underground House Roof

That's definitely a set it and forget it envelope. Ramp up on seasonal startup.

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.


@ 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.


@ 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.


@ 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!
