Frequently Asked Questions

Can our systems be installed using an existing steam boiler?

Radiantec : FAQ Frequently Asked Questions, Radiant Heat, Sy...
Yes, this is entirely possible. Temperature control is the issue. You can use one of our heat exchanges to change the steam to hot water. Then you can use a mixing valve to control temperature of the hot water. You may want to consider the use of a safety control.

Can UFAD systems be installed in existing buildings, during retrofit projects for example?

Underfloor Technology Frequently Asked Questions
Due to the tremendous size of the existing building stock, retrofit construction will play a dominant role in the future for the building industry. Projects requiring the addition of an HVAC system often encounter the problem of having limited space for accommodating ducts and other components. By eliminating large overhead ceiling ducts, the total plenum height required in UFAD installations is less than that for ceiling based systems.

Can all our systems be installed retrofit into an existing home?

American Industries Corp. - Frequently Ask Questions
It depends on the home being retrofitted as to whether or not a particular system can be installed. As always it boils down to access in the attic, under the house, and/or between walls etc. Have one of our technology consultants look at your home.

Can I use my existing boiler for both radiant heating and baseboard radiators?

Radiantec : FAQ Frequently Asked Questions, Radiant Heat, Sy...
Yes you can. All you need to do is provide a Radiantec mixing valve to step down the temperature of the water to the radiant circuits. You mix hot water from the boiler with return water from the floor to provide a lower temperature.

The water in my steam boiler is fluctuating, how do I prevent this?

Desco Energy
a fluctuation in the water line of a steam boiler is referred to as Surging. A small amount of fluctuation is not uncommon, but if severe enough can cause a number of undesirable conditions, i.e. water hammer, inefficient operation, etc. Severe surging is recognized by a water line that is fluctuating more than one-inch or when water is visibly running down from the top of the sight glass. Surging is caused by a violent boiling action as a result of oil on the water surface.

How safe are the systems, can the boiler explode?

VapourTek Steam Cleaners - FAQ's
The boilers are all pressure tested to well over the operating pressures of the systems. They are all constructed from stainless steel and have built in safety devices. If the thermostat fails there is a pressure stat that will cut off the power and if this fails there is a safety valve that will release the pressure well before the boiler reaches its maximum safe pressure.

Can the heating and cooling systems be installed in an existing house?

FAQ's
Yes, on a case-by-case basis. After a brief interview is completed, a technician would have to visit the site to make sure that the installation is technically feasible.

Do you have referrals of systems you have installed with existing lawns that I may go and look at?

copyright
Yes we have referrals. Please CONTACT US and we can give you the address of someone in your area and tell you how long ago the system was installed.

For my steam systems what do you suggest?

Industry Solutions
Metso Automation can supply valves for the steam generator-fuel oil system through the condensate system. For fuel oil, the Wafer-Sphere® and FM approved Jamesbury brand ball valves are used throughout the system. For steam from the boiler house, to the process and to the turbine Wafer-Sphere with Gear and /or Quadra-Powr actuators are used. The turbine automatic shut-off valve is most often a Wafer-Sphere/Quadra-Powr. For condensate lines the full range of Value-Line® are applicable.

Can my service be installed using my existing cable jack outlets in my wall?

RMK Technologies: FAQs
If your existing cable jack outlet is of sufficient quality, our installers may be able to provide DISH Network service through it.

My new steam boiler cycles very frequently, what could be wrong?

Desco Energy
A new steam boiler could be short cycling due to a number of reason. The first may be something as simple as having installed a room thermostat that has an adjustable heat anticipator setting with in it. This setting needs to be at 1.2 for the longest cycle setting as possible allowed by the thermostat. The best thermostat for this is the standard Honeywell T87F round design unit that has this internal setting on the unit.

Why should I not use deionised water in my Live Steam boiler?

Hornby Live Steam - FAQ - Customer Support - Hornby
Deionised water will readily take on new ions from metal with which it comes into contact - Copper, Zinc and Silver seem to be particularly susceptible. Investigations have shown that the Silver soldered joints in boilers can weaken and eventually fail, with potentially disastrous results.

If I purchase a 15 P.S.I.G. steam boiler can it be converted to water at a future date?

Bryan Boilers - Since 1916
The maximum allowable working pressure (MAWP) on water for this unit would be 30 P.S.I.G., provided the unit was dual stamped. Yes! However you must consult the Factory or your Bryan Manufacturer Representative for the appropriate price addition.

Can ChefTec be integrated with our existing systems by using ODBC?

Frequently Asked Questions about ChefTec from Culinary Softw...
ChefTec uses the Paradox relational database for storing data. These Paradox tables are accessed internally (from ChefTec) using the Borland Database Engine (BDE). Paradox tables are non-proprietary and they may be accessed by any software package that provides ODBC support (such as MS Access). If a third party wants to integrate their system with ChefTec, they should only read the data in ChefTec (not write to it).

Are there any bags or filters to buy for the steam only or steam & vacuum systems?

VapourTek Steam Cleaners - FAQ's
No. The steam only systems are designed to use only tap water so there are no other elements to purchase. The steam & vacuum systems also use only tap water, both in the boiler and as there filter. Water is the best filter medium as it will hold elements as small as smoke particles in the water. Virtually pure air is blown out of the back of the system through a washable final foam filter. There are no bags or filters to purchase on an ongoing basis.

How do I get my non-U.S. keyboard modmap to be installed when using xdmcp?

Cygwin/X Frequently Asked Questions
Pavel Rybnicek] The X Keyboard Extension doesn't work with AIX. The X Keyboard Extension is enabled by default, so you must disable it with the -kb parameter. An example command line follows. First check if you are able to change the server to another layout via XKB. The german layout will be good for testing: setxkbmap de -model pc105 This worked if pressing "Shift" and "8" produces "(" instead of "*". If it worked then you can skip the next paragraph.

BLAIR: It's steam. Why do they have that?

NASA - NASA EDGE Show 8: Space Shuttle Launch - STS 118
BLAIR: Sound suppression? So, that's not from the rockets. That's something totally different. Why would they need to suppress the sound? We're far enough away so that we can hear it without ear damage.

Can the server and client be using different operating systems?

Synergy Frequently Asked Questions
Yes. The synergy network protocol is platform neutral so synergy doesn't care what operating systems are running on the server and clients.

Do you steam before using the mask?

preeventACNE.com > Frequently asked questions about Devin...
The answer to this question appeared to depend on the reason for using the mask. Most users who used it to remove blackheads and plugged pore said they always steamed before using the mask. Some people who used the mask on the shoulders used a warm flannel instead of steaming. Those using the mask as a facial did not bother with the steaming step. Users wanting to clear and prevent spots always used the steaming step.
