Here are some of the things we have done with our RCC when it comes to mobile homes.  It is my hope that others who work with RCCs will try these things also to hopefully open up a new market for their energy efficiency companies.

-------------------------------------------------------------------------------------------

In the San Francisco bay area a few years back.  I got a call from a painter that works for the East Bay Regional Park District, the worlds largest independent park district corporation.  72 parks with many buildings at each park.

He told me they had one single wide trailer in the Oakland hills that they had a very hard time keeping the older caretaker warm.  It was a 33 footer and had a gas heater at one end and a metal heating duct that ran the full length underneath the trailer.  It was 12' x 12' if I recall correctly.  He said fiberglass insulation had been in place under the entire traler for many years.  When ithe heater came on, it ran on high until the thermostat was satisfied, then it shut off.  Rodents had made off with the majority of it to the point you would not even consider it there at all to help retain any heat.  What was left was removed.

They did a simple 3-day test of our RCC..

They turned the heater on the first morning and brought the interior up to 72 degrees .  Then they shut the unit off.  They sprayed our RCC on the entire undercarriage of the mobile home including the heater duct.  They gave the RCC three days to cure and then repeated the same test as before.

The district was kind enough to issue me a statement and report.  I will be happy to send it to anyone interested.  Their report indicates an 84% reduction in heaster run time and substantial; air temperature increases at the floor registers after that application

 

 

As far as I am aware, this was the first time an RCC was ever used for this purpose.  Many thanks to the EBRPD folks for their statement and report..  Their test and report proved an 84% reduction in heater run time.

INTERIOR CEILINGS AND WALLS

Coating interior drop ceilings to beautify, save energy and cover the unsightly stains they all seem to have.  This is a mobile home in Sacramento owned by a retired gardener who specialized in Bonsai trees.  His wife said he was a chain smoker for many years and smoked inside the mobile home alot as the ceiling panels were obviously stained by nicotine.  Several stained areas from previous roof leaks.

The ceiling panels were gently cleaned with a light mixture of TSP and water via a sponge mop.  The RCC was painted on after they had dried.  The wife said she felt the difference in interior temperature the first night and loved the way it looked.  This was done in mid summer.

I happened to drive by their home that December and stopped.  The wife said it still looked like day one and they both felt the difference n summner and winter comfort levels.   She said their electric bills were noticeably less than the year before.  I did not ask for specifics.

Here are some photos.

MARIPOSA MOBILE HOME TEST VIDEO  This is a video a homeowner made in Mariposa California.  They did their own test of our coating before coating the emtire mobile home.

 ----------------------------------------------------------------------------------------------------

Water heaters can be coated to retain heat inside.  I have no pictures or statements of this application..  I DO HAVE pictures and a statement of how well our RCC did on hospital boilers and steam pipes that I can send anyone.  Coating those surfaces with our RCC resulted in a drop ion the surface temperature of those metals from 267-degrees, down to 155=degrees.  This was a 35% reduction in heat loss per the chief engineer.  I would expect a similar reduction in heat loss when applkied to a residentiall water heater.

Using an RCC as an exterior paint, or roof coating goes without saying.  You would have 'Cool Roofs' and 'Cool Walls' that keep the unit cooler in the summer and warmer in the cold months.

---------------------------------------------------------------------------------------------

       --------------------------------------------------------------------------------------------------------------------------     

 

They had to run their  well water puimp for 20 minutes before they could get cool water from the tap.  Now,. the cold water is always cool.  On a sunny day, after 11:00 am, you couldnt touch the galvanized tank it was so hot.  Now it is cool and as cold as the water coming up.

--------------------------------------------------------------------------------------------------------

 Not so much an energy saving aspect as a safety aspect and USE of RCC's.  AS I WAS TOLD by a government painter.  Fire marshalls inspect propane tanks every so often.  The propane distributors carry special 'Propane tank paint'  That paint degrades quickly and has to be repainted every every 1 to 2 years.

The large and small units shown here were needing re-painting.  The painter used our RCC on both.  He met with the lady inspector from the local Fire Marshalls office.  He explained the use of the RCC and she felt the tank.  She loved it and then said that heat from the tank would expand the gass inside and cause it to leak past the seals on the unit.  This is a major  fire/explosion hazard.  This is one of the reasons the tanks are placed some distance away from the homes / mobile homes.  Painting these tanks with an RCC was definitely a good idea.

About a month later she bought some and applied it to the roof of her mobile home.  She gave us a very nice statement below.

Only picture I have of a water heater coated in an attic at the same time as the AC unit, plenum and ducts.  Sorry it came out very blurry.
