Boiler upgrade - Things to know.
So you have decided to upgrade you existing boiler? My advice is if you are researching on the internet to keep the following in quote in mind: “ A designer knows he or she has achieved perfection not when there is nothing left to add, but when there is nothing left to take away.” Also it is worthy to note that most review sites and forums originate in the UK, which is the largest single Gas Boiler Market in Europe and British people are very buy British minded. In our opinion maybe this is why, for example Opel is branded Vauxhall in the UK & Worcester Bosch retains the word Worcester in its branding!
Then Consider this:
The modern high-efficiency gas boiler has reached its zenith. These boilers have made significant strides in energy efficiency and reliability, making them a top choice for homeowners looking to upgrade their heating systems. While electronically they are improving or becoming more high-tech day by day. With their proven track record of efficient and reliable heating, high-efficiency gas boilers is an excellent investment for any home.

Meeting expectations & the evolution of Gas Boilers.
Gas boilers in the 70s and early 80s were simple and had low technology with basic one-year warranties. They heated water that circulated around the system via an external pump to provide heat to radiators and hot water. Although these boilers lasted for over 20 years for wall-mounted gas boilers and 30 years for floor gas boilers, they were considered highly inefficient by today’s standards. While parts for these boilers are still available, replacing one part often leads to replacing other main parts. Today, these gas boilers are considered obsolete and unsafe.
In the late 80s and early 90s, more technically advanced gas boilers appeared on the market, which were lighter, slightly more efficient, and much safer. However, their life span became shorter and was adversely affected by water quality. Poor installation and maintenance could lead to a service life of just 10 to 15 years, while a well-installed and maintained gas boiler could last up to 20 years with up to three main parts replaced during its service life. Many manufacturers developed a large business in spare parts for their gas boilers, although some of them developed a bad reputation during this era, which was often undeserved.
People expected the same from their modern boilers as they had seen or heard of from the older boilers. Plus many of the newer boilers we fitted in large housing estates where quantity and installation speed was more important that quality, in older houses they were fitted to systems with dirty pipework and radiators containing sludge deposits that adversely effected the main components of these modern gas boilers. I refer back to these gas boilers not being as robust as their predecessors. Very few contractors had even heard of or considered power flushing the old systems or pre -commissioning power flushing of new systems. This mean that debris that got into the pipework during installation remained in the system as did soldering fluxes, jointing compounds, swarf etc. used during the installation were able to – over time – attack and block the gas boilers heat exchangers. In the early to mid-00’s the emphasis shifted to High efficiency, to achieve this three major components had to be redesigned and a fourth added.
The Heat exchangers: The Gas boilers heat exchangers had to be totally rethought and redesigned, some of the earlier heat exchangers were extremely troublesome and were adversely affected by water quality. Intergas, a Dutch manufacturer were ahead of the game in the mid-nineties, they claim they have not had a heat exchanger failure in over 20 years. Viessmann, a German manufacturer and the No.1 selling boiler in Germany for over 12 years also has a very robust Spiral high grade stainless steel heat exchanger. Some of the British Manufactures were left playing catch up. Ariston a brand often overlooked also have a robust heat exchanger. Other Boilers worthy of note are in our opinion are; Ideal & Worcester Bosch.
Gas Valves: The modern condensing gas boiler has a totally different solenoid valve that works in conjunction with the fan and the correct sizing of the gas supply pipe is very important.
Fan: The Gas Boilers works in conjunction with the up graded gas valve to allow modern Gas Boiler to modulate and use even less gas than the older standard efficiency and many of the early High efficiency Gas Boilers. Condensate Drains: When we burn Natural Gas we produce a quantity of water, with the older Gas Boilers this was evaporated by the high flue gas temperature, however as the Gas Boilers High Efficiency Heat Exchangers harvests more heat from the flue gasses – this vapour turns to condensation, hence the name Condensing Gas Boiler. The produces a steam plume from the flue terminal and the condensed water drains through the heat exchanger and into a trap at the bottom if the boiler –then runs out to a drain. It’s is important that the drain is dealt with correctly as its quite aggressive and can freeze easily in the condensate pipe in adverse weather condition, when you need your boiler most.
