One of the most common mistakes made when selecting a new boiler systemto power your hydronic heating is to rushthe decision. If your current boiler isn’t working, we understand that there can be a lot of pressure to find a new one as quickly as possible, but this doesn’t mean that you should walk into a decision blindly. Do some careful research and be sure to consider the pros and cons – this little extra effort at the beginning will pay for itself many times over in the future. We have compiled this guide in order to help you reach a decision.
Standard or Condensing?
At Cambro, we have two types of boilers systems for you to choose from – standard or condensing. These units both use gas and are both mounted to the wall, but the difference becomes apparent when comparing their installation and running costs.
Standard –Standard efficiency units are chosen for their ease of installation, which translates to a lower initial cost. They operate at around 80 to 85% efficiency and can be run on natural gas or LPG.
Condensing – Though more expensive to purchase and install, condensing boilers – or ‘high-efficiency boilers’ – run at about 90 to 95% efficiency, making them an excellent choice for keeping costs low into the future.
The boiler system that you choose will be dependent on the size of your hydronic home – and the power that your hydronic unit needs to effectively heat the space. Another factor that can influence the size that you purchase is your available real estate; if you only have the space for a relatively small unit, then the decision has been made for you!
Which Power Source?
When it comes to the power supply of the boiler system, you will also have a number of methods to choose between. Whilst each of these methods will be highly effective at providing energy to your system, it is important to keep in mind that not all will be suited to your home.
Natural Gas – An excellent allrounder, natural gas accounts for around 90% of all boiler systems in Australia.
LP Gas – if natural gas isn’t available, choose LPG. It offers an excellent solution for both running and installation costs.
Electric Heat Pumps – A heat pump can be a great choice for underfloor heating in our mild Australian climate. However, it can’t be used to heat radiators, as their temperature requirements are too much for the heat pump.
Timber Pellets – Though more expensive to install than their alternatives, timber pellet-powered boilers are often the only choice for rural areas with limited services. Hydronic heating enthusiasts may also prefer this ‘traditional’ option.
Electric Boilers – Many choose an electric boiler if they can’t access gas. Though running costs can be high, these can be offset with solar energy.
Whilst the information that we have provided you with in this article will go a long way towards helping you to make a decision, we understand that there are a number of other factors that you will have to take into account. When choosing a new boiler system for your hydronic heating, you should also consider how quickly it will be able to heat your home, how compatible it is with your existing hydronic heating system, the location (whether it can be installed indoors or on the exterior of your home), and of course, where it has been manufactured.
At Cambro, we only use units that have been made in Europe – the world leader in hydronic heating systems. Contact our team on 03 8762 5690 to learn more about the best system for your home.
