We get asked this question a lot, so I thought I would write this article so you can make a more educated decision.
By law you must choose a high efficiency condensing boiler with a Sedbuk Boiler Installation rating of either A or B. A rated boilers have an efficiency of 90% and above and band B boilers have an efficiency of 86% – 90%.
The obvious benefits of a new condensing combination boiler Boiler Service are that they are a lot cheaper to run, and a lot better for the environment, there’s also a good chance that a new boiler installation will add to the value of your property depending on the condition of your old system/boiler.
There are many manufacturers of boilers around some better than others and the price often (but not always) reflects this, my personal recommendations for a good value reliable band A boiler is the Baxi Duo- tec, or Ideal logic +. The Duo-Tec was awarded Corgi and Which magazine boiler of the year in 2007 and has an efficiency of 91.5%, the Logic + is about the same price as the Duo-Tec but comes with a 5 year warranty as opposed to the Duo-Tec’s 2 year warranty., I personally think they are just as good as each other as I have fitted both, it just so happens that Baxi have a better reputation than Ideal. If you have money to burn then you could opt for a Worcester Bosh or Vailant boiler, but I don’t think they warrant the extra expense personally.
Whoever you choose to fit your new boiler must ensure that the following are carried out as part of the installation in order to meet all relevant regulations:
Thermostatic Radiator valves – Used to control each radiator individually and in turn will save you money
Room stat – Normally wireless and used to control the temperature of the room, saves money.
System flush – This is needed mainly for your boiler warranty, there’s two methods one is a powerflush and one is a hot and cold flush, in a nutshell the system must be clean fro sludge and magnetite build-up as newer boilers are more perceptive to sludge damage, another good idea is to get a filter fitted which offers long term protection.
