Series H 1512 Posted by Elaine on 9/13/2006, 8:28 pm What are the ceiling heights on the main floor and second floor please? Elaine  Post a Response

Re: Series H 1512 Posted by Rob Young on 9/14/2006, 10:05 am, in reply to "Series H 1512" Hi Elaine: The ceiling heights are as follows: The main floor is 8'-1" high. The second floor is also 8'-1" at the exterior walls but vaults up to the center acheiving a height of 10'-4". Rob Young Cottage Division Manager robinsonplans.com  Post a Response

Re: Series H 1512 Posted by herb ripke on 10/3/2006, 8:11 pm, in reply to "Re: Series H 1512" if you want to run forced air heat from the mechanical room to the second floor bedrooms, you will need to have a minimum of 9'0" ceiling heights on the first floor, unless you are willing to live with 7' ceilings in your kitchen area!!!  Post a Response

Re: Series H 1512 Posted by Rob Young on 10/4/2006, 12:31 pm, in reply to "Re: Series H 1512" Hello Herb: I have to disagree with your statement. There are two ways to handle running the main supply ducting for a forced air furnace on this plan and neither has such a negative impact as you are trying portray. The first method (used with open-web wood trusses as spec'd on our plans) would be to co-ordinate with your floor truss supplier to have them manufacture an opening in the truss to allow for the main supply ducts to fit between the webbing. After you reach a point past the stairwell opening, this is no longer required as you can then run the main ducts parallel with the trusses in the space between them and run your individual supply lines thru the webbing of the trusses. The second option (primarily used with I-Joists) does force you to drop the ceiling but not to the degree you have stated. You would simply create a dropped bulkhead over the kitchen cabinets along the outside wall to suit the main ducts. From there you can then run your individual supply lines up into the joist space space over. This is not that intrusive as normal kitchen cabinets are mounted at 7 feet so therefore this bulkhead would only take away from the space over them not the entire kitchen ceiling.

Re: Series H 1512 Posted by HERB on 10/15/2006, 9:34 pm, in reply to "Re: Series H 1512" YOU STILL HAVE TO CONTEND WITH THE MAIN CENTER LINE BEAM THAT MUST SUPPORT THE JOISTS, IN THE CASE OF THE OF THE OPEN WEB FLOOR JOISTS, YOUR OPENNINGS FROM THE LIVING/DINING ROOM AREA INTO THE KITCHEN CAN BE LESS THAN 7 FEET, DEPENDING ON LOADING REQUIREMENTS. THESE TYPE OF JOIST CANNOT BE DESIGNED TO CARRY THE ROOF SNOW LOAD AT THE NEW STEP OUT DESIGN OVER THE PORCH DECK AREA. YOU MAY BE REQUIRED TO USE BEAMS, THEREBY ELIMINATING ANY HOPE OF GETTING ANY DUCT WORK TO THE MASTER BEDROOM AT THE DOORWALL. IN THE CASE OF THE TJI'S THAT YOU MENTIONED YOU ALSO HAVE THE CENTERLINE BEAM TO CONTEND WITH. IN MY CASE THIS BEAM BETWEEN THE LIVING/DINING ROOM AREA HAD TO BE 16" DEEP BASED ON THE ENGINEER I USED. HAVING BUILT THIS HOME, I WOULD STRONGLY RECOMMEND THE 9 FOOT FIRST FLOOR CEILINGS, THIS WILL ALLOW YOU ALMOST ALL OF THE FLEXIBILITY YOU NEED TO INSTALL ANY TYPE OF HEATING SYSTEM YOU MAY DESIRE.  Post a Response

Re: Series H 1512 Posted by Liz on December 21, 2007, 11:45 am, in reply to "Re: Series H 1512" We built an H Series home in 2006 in Washingon State and faced the same dilemma in installing a forced air propane system. Although we had designed in 9' ceilings on the first floor we did not want to lose that wonderful height to ductwork - so we combined heating sources. The first floor has propane forced air plus a propane fireplace; we did have to drop the utility/laundry room ceiling a foot for the return air ducting with its register on the upper wall of the stairs. The second floor has electric hydronic baseboard heaters (Marley - very quiet) in the bedrooms and pic-a-watt heaters in the bathrooms (there are also heated towel racks). Because newly built houses have such efficient insulation and hot air from the first floor rises to the second, we hardly ever turn on the baseboard heaters or use the pic-a-watts.  Post a Response

Re: Series H 1512 Posted by John B on December 21, 2007, 11:06 pm, in reply to "Re: Series H 1512" ...and here was another way it was handled. I built a H series home in North Carolina and no ductwork was needed in the ceiling between the first and second floor. Two separate HVAC systems were used. One was in the crawl space that provided the heat and air for the first floor through ductwork. There was a separate system in the attic that provided the heat and air to the second floor through separate ducts.  Post a Response
