Virtually every new boiler these days is what is known as a condensing boiler, which saves more energy than older conventional boilers by recovering heat which would ordinarily have been lost through the flue of the boiler. While a new condensing boiler is more efficient than the previous conventional boilers, their efficiency can vary wildly depending on the brand you choose or the model you buy. These days, every electrical appliance is rated on an energy efficiency scale – it’s worth paying the small extra amount to buy a top rated efficiency boiler, than something which is more average. A top of the range boiler can be as much as 90% more efficient, which results in as much saving in money terms as well.

However, while from the above a condensing boiler might sound great, there are some key points you need to know before you go out and order one from your local heating and plumbing specialist.

* The conventional system claims to achieve efficiency of anywhere between seventy and eighty percent. However, this is eclipsed by condensing boilers which tend to have an efficiency of at least eighty-seven percent, and many are well over ninety. The percentage may sound relatively small, but it is big enough for you to start to notice a difference in the money you are paying every single month.

* A condensing boiler can be fitted to almost all existing central heating systems. You might need a few changes in heating controls, along with perhaps new radiators or piping. This all depends on the quality and age of the previous system. Ask a specialist to take a look.

* Condensing boilers lose efficiency if only used rarely. For example, in the summer you might only ever use it to heat up water every now and again. In this case, the boiler heating up the water would be much more inefficient than when it’s regularly used over the winter.

* A condensing boiler can be a bit unsightly in comparison to an older conventional boiler, with water vapor being pumped out of the boiler’s flue.

* A Condensing boiler needs to discharge into a drain via their own smaller drain pipe, meaning that if you don’t have the facilities, or perhaps you don’t have the permission from your landlord to do such alterations, you won’t be able to install a condensing boiler. This is where a majority of work needs to be carried out, to connect the boiler to your drainage system.

* With the potential amount of work required to be carried out it’s worth having the condensing boiler installed at the same time as other household work. Do you have some other DIY plans? If so, try and sort it, so your boiler installation happens at the same time. Changing piping and radiators can be a big and messy job! This way you minimize disruption from the installation, rather than having two projects going on at separate times

Maintenance is a major factor to consider. Buying a simple machine is better when it comes to maintenance. Find out if you can pull out the compartments easily so you can clean them without a hitch. Also, find out if you can easily clean the condenser coils at the back of the condensing boiler. Avoid buying modern models with advanced parts. You might have trouble finding a replacement for those parts in the future.
