Boiler Scrappage Discount - £400 Johnston Scotia has a proven track record in carrying out professional boiler installations, with over 30 years in the plumbing and heating business they are a name you can trust. Having launched the first condensing boiler Having launched the first condensing boiler in 1989, the leading Dutch boiler manufacturer Intergas is now one of the largest manufacturers in Europe with over 40 years' experience. Taking condensing technology to new heights with a unique two-in-one heat exchanger, our groundbreaking energy-efficient boiler designs have made us first choice with many households throughout the UK. Compact and lightweight, the Intergas Compact HRE range represents the only double condensing boilers now available in the UK. With significantly fewer moving parts, these revolutionary boilers deliver more reliability for less servicing. In fact, since its introduction in 1996 our heat exchangers have not suffered one single mechanical breakdown. Every Intergas Combi Compact HRE boiler features our unique back-to-back, two-in-one heat exchanger that reduces heat losses and delivers the optimum heat transfer for an exceptionally economic performance year after year. Separating the circuits for heating and hot water also means there's no need for a diverter valve or secondary domestic hot water plate heat exchanger, eliminating the source of possible future component failures. This is why every Intergas heat exchanger carries its own 10-year guarantee. • NO diverter valve • NO valve motor • NO auto-air vent • NO hot water plate heat exchanger • NO air pressure switch This minimalist approach to boiler design also delivers noticeable energy savings with the accompanying lower bills, especially as a switch-mode power supply reduces stand-by losses to almost zero - simply because, until the boiler is called on to heat, only a negligible amount of electricity is used.

The circulation ratios of 1. Natural circulation industrial boiler - 10 to 15 2. Natural circulation utility boiler - 7 to 9 3. Assisted circulation boilers - 2 to 4 4. Forced circulation / once through boiler - 1 Q What are the boiler mountings. A.

It is the operating range of boiler from maximum capacity to minimum capacity in which the boiler can run efficiently without any external fuel support . The higher turn down ratio greater the efficiency of boiler. For example if the boiler is designed 80mw and can operate up to 20mw without any external fuel support and any variations of parameter then the turn down ratio is 80/20=4. Q. What is boiler efficiency. A. It is the ratio of heat output to heat input of the boiler. Boiler efficiency= Heat output / hea
