A condensing boiler extracts additional latent heat via its high efficiency heat exchanger. The fuel products are cooled to such an extent that condensation occurs within the appliance and the flue. This condensate has to be drained away to a suitable point. Running costs are substantially cut whilst the boiler is condensing. See similar questions...

A condensing boiler is very efficient type of boiler which converts more than 88% of its fuel into heat, compared to 78% for conventional types. The Building Regulations currently require that boilers installed in homes in England and Wales should fall into the SEDBUK band A or band B categories (high efficiency or condensing boilers). There are however, a few occasions when it is too difficult or too expensive to install a condensing boiler - these are known as exceptions situations. See similar questions...

Many years ago, the heating industry worked diligently with the American Society of Mechanical Engineers to establish standards related to the safe and reliable construction of copper, steel and cast iron pressure vessels to heat buildings. At the same time, the water heater industry made it clear that its pressure vessel was not a boiler and never intended to be a boiler. ASME design certification and testing have given the public a safe, reliable boiler. See similar questions...

All of the companies we contract with offer full-service contracts. A standard contract covers parts and labor, annual tune-up and cleaning and vacuuming, as well as emergency service. No. NYPIRG membership consists of a tax-deductible contribution of $30 or more. Fuel Buyers Group is a NYPIRG program that NYPIRG members can participate in. See similar questions...

All local, state and federal codes must be met by the installer. Those codes vary from location and state and application. In most cases a boiler with a capacity above 200,000 BTU per hour must be installed by a contractor with the appropriate licenses and insurance. In many states however, those codes do not apply if the usage is to provide heating for growing or raising livestock or poultry or for greenhouse heating applications. See similar questions...

You need to clean the condensing unit at least once a month to remove dirt, which are clog between fins. You also need to check and remove obstacles that hinder airflow in and out of condensing unit. This will make sure the air circulation of the unit is not blocked. It can affect the cooling efficiency, a shorter See similar questions...

The leading cause of this problem is not using a vacuum controller. Most likely the maximum vacuum of your vacuum pump is too low, and consequently the vapor pressure temperature is lower than the condenser temperature. We recommend to use the Vacuum Controller V-850 with valve unit or with a Vacuum Pump V-700. Yes - Multiple Rotavapors can be connected to one Vacuum Controller; however, the nominal vacuum pressure must be the same for all Rotavapors. See similar questions...

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. See similar questions...

The Boiler Challenge is scheduled on a request basis. This means that you tell us when you want to plan your visit...any day of the week, and as long as another group does not have that time, we will do everything in our power to get you scheduled during a time that's best for you. Remember, this is an outdoor activity, so it must be during daylight hours, and weather could play a factor. See similar questions...

Time slots fill in quickly, so it's best to get your request in as soon as you can. We ask that you put in your schedule request at least two weeks prior to your preferred date so that proper arrangements can be made. See similar questions...

It won't be the Fuel Buyers Group who cleans your boiler. You will call the oil company assigned to you to arrange the tune and clean. NYPIRG negotiates with local oil companies in your area. Our agreements vary from company to company, so the price with your company wouldn’t necessarily be the same as the price of that a member with a different company. See similar questions...

A - Select option A on the BIS Menu, Building Information Search. You will be directed to the Building Information Search screen. You will be required to enter the precise address, the house number and street name or the block and lot number or the Building Identification Number (BIN). You will be directed to the Property Profile Overview screen. Scroll down to the bottom of the page to "View Boilers" which will direct you to the Compliance Boiler Query screen.

Boiler exemptions are no longer required. Despite the introduction of the PECPR Regulations in 1999, certain parts of the Boilers, Lifts and Cranes Act 1950 remained effective. Because of this, it was necessary in order to operate a boiler in unattended or limited-attendance mode to be issued with an exemption from section 37(3) of the Act. The Boilers, Lifts, and Cranes Act was repealed on 16 January 2006, and as a consequence these exemptions are no longer issued. See similar questions...

A place where high-pressure salespeople use banks of telephones to call lists of potential investors (known as a "sucker lists") in order to induce them to purchase speculative securities, sometimes called "the stock of the day" that the firm has a large inventory of, to be unloaded at significant profit to the brokerage. It is called a boiler room as an analogy to a pressure cooker due to the high-pressure selling. See similar questions...
