ok, I believe, although not positive, that the round thermostat on the side of the boiler indicates the supply water temperature. I watched it yesterday when the furnace kicked on and it heated up to 180 degrees F. The baseboard heaters are 3/4 copper with silver aluminum fins have existed in...

I don't know what the water temp is, but I will take a look tomorrow when the furnace kicks on as I just noticed that there is a thermostat on the side of the boiler. I do know that the Fondital Blitz listed the BTUS based on 176 degrees F and I think the Baseboards work on that temperature...

I believe this will effectively be a new zone. There are currently 3 feed lines coming off the large copper line coming out of the boiler. Each line has Orange handed values and Blue handled drain valves. There are also 3 return lines. The one line and return only went to the Baseboard...

I imagine a tankless water heater would work, but I would like to use the existing system if that is possible.

I just did an addition adding a first floor 5 x14 room for a bathroom with schluter dita-heat electric floor and a second floor room which is 13.5 x 13.5 and currently has no heat. We have a boiler that circulates hot water through 3/4 inch copper to 3/4 inch baseboard radiators throughout our...

Thank you all for your help. The drains are in, and now I am ready to gravel, grade and setup the rebar for the concrete pour!

Maybe the 2 "J" hooks are overkill. I wanted to connect the support for the 4 horizontal runs to the existing foundation. I have attached another idea. What do you think? Yes, the for the new monolithic foundation will actually be 4"inches above the existing foundation that is exposed...

Tom, I will need to read this a few more times to make sure that I understand, but thank you and I will be sure to talk to the building inspector about this before I pour the foundation.

Not sure what You mean by "J" hook over the Inside bars, so I changed my drawing. Please let me know what you think. I also attached a picture of my worksite so you can see my current progress - no rebar yet. The drain lines for the bathroom are hopefully going in tomorrow if the plumber...

I see the big footings, but I do not see where the rebar is placed unless that is shown by the arrows in the concrete. Here is a good picture of what I am trying to accomplish. What do you think of this design - only replace the wire mesh with #3 rebar.

Nealw I have to go to work. I greatly appreciate your help and I will be sure to read your response when I get home tonight. Thanks

You said that we don't want a 3' high footing and that you put in a grid of rebar. Could you please describe the grid that you use. The inspector told me to use #4 rebar, that is the only reason that I was planning to use that in the 3' footer/foundation. My dad had 3 wire mats left over from...

Thank you Snoonyb - you have been very helpful!

Snoonyb ...... It's not the number of bars, it's maintaining the "cost" away from soil, which you had addressed with the spacers at the bottom. I am not certain what maintaining the "cost" away from the soil means. I think I understand - you are concerned that the rebar may be exposed on the...

Snoonyb, I have watched many videos where 2 horizontal runs of rebar where placed in a footer that is about 1 foot thick and then block is laid on the footer. I am not planning to use block, and since my footer/foundation is 3 feet deep, I assumed that more rebar was necessary. That is why I...

Snoonyb, To answer your question about the 2 story requirements - the exterior wall under the low slope is cinder block and the foundation below that wall is at least 2 feet thick. I believe that will support the second story. You said that my rebar cage is overbuilt, please tell me what...

My house is two stories on a slab in Pennsylvania. My house is L-shaped. I am putting on an addition of a 14' by 14' room on the second floor and a bathroom that is 14' by 5 1/2' on the first floor (the bathroom is smaller due to a previous kitchen addition on the 1st floor). I jack hammered and...
