Choosing a residential boiler system instead of a typical HVAC unit can be quite different because there are so many different things to consider and different attributes the modern boiler unit can have. One of the things you will come across is high-efficiency and standard-efficiency models. Take a look at some of what you need to know about the two designations.
What's the difference between high-efficiency and standard-efficiency boilers?
The primary difference between a high-efficiency and standard-efficiency boiler is that the high-efficiency units have been rated as having a high fuel utilization efficiency by the manufacturer. Therefore, high-efficiency models are better capable of converting fuel into heat during operation. Standard-efficiency models use more fuel to generate the same amount of heat, so they can cost more to operate. The U.S. Department of Energy states that replacing an old boiler system with a new high-efficiency model can cut your fuel cost by as much as half. This is is definitely a noteworthy amount of savings to consider if you have a standard boiler unit that is in need of repairs.
Are there any downfalls to high-efficiency boiler systems?
The primary downfall to high-efficiency boilers in a residential setting is they can be more costly to install and can be much more space-consuming than a standard model. Additionally, if something goes wrong with a high-efficiency unit, the repairs can be a little more costly, which can be a burden to some homeowners. Some common problems with high-efficiency boilers that would require professional repair include:
- Corrosion caused by acidic condensate in the lines
- Return water is getting too hot and it is inhibiting the condensation process
- Water flow is too slow and causes short cycling
- Intermittent ignition problems
Why does it cost more to install a high-efficiency boiler system?
High-efficiency boiler systems can have to include upgrades to things like the ventilation system, water supply lines, and fuel delivery methods. The boiler unit may even require more space in the house just because the unit is bigger. High-efficiency units take longer to install because of both factors, which means the installation can cost considerably more than a standard-efficiency. Even though opting for a high-efficiency model will cost you more on installation initially, the cost savings over the long term can be substantial enough to recoup the costs.
Overall, there truly are a lot of advantages to a high-efficiency boiler system, but a standard version can serve some homeowners well.
