Another basic component of the hydronic heating system and outdoor wood boiler is the water circulation pumps. But if your boiler is outside, this application becomes more so. These pumps ensure that hot water spreads throughout your home in the most efficient manner, giving you room heating in a controlled and consistent manner. It achieves this by constantly circulating water from the boiler to different heating elements such as radiators or underfloor heating systems.
Although very vital for pumps, the practice has many myths of how it works and what really is going on. This article will look to bust some circulating pumps myths in the scope of outdoor boilers to give you a better view when determining the right heating system for your house.
Myth 1: Any Pump Will Do for My Outdoor Boiler
Myth: Many people think that any pump will do just about anywhere in an outdoor boiler system.
Fact: This is a potentially deadly misunderstanding. With an outdoor boiler, a general-purpose pump will not cut it. Circulator pumps, for hydronics, need to be hydronic-rated. In experience, the best pumping power available for an outdoor boiler is contained in the 1/6 HP pump-a more-than-capable unit in most applications. The wrong pump means a less-warm-than-promised tank as well as the possibility of damage to the system itself.
Myth 2: Size Doesn’t Matter as Long as the Pump is Powerful
Myth: User belief. Some users assume that a more powerful pump will always be the better choice for their outdoor boiler.
Reality: Yes, while power is important, the size of the pump is just as important. In the website of Outdoor Boiler, they carry two standard sizes: the 1/6 HP pump for most installations and a smaller 1/25 HP pump for specific situations. The large pump will be best for systems that have multiple bottlenecks, such as filters and heat exchangers, and longer runs. The small pump would be used only when the run is less than 75 feet and when the bottleneck is minimal. Oversizing will mean inefficiencies and higher energy expenses.
Myth #3: Circulation Pump Can Be Installed Inside the Building
Myth: To many homeowners, it makes sense to put a circulation pump inside for better performance.
The Reality: That’s a big mistake. Air lock can occur when the pump is installed indoors and this will cause it to fail. The right thing to do is keep the pump at the rear of the outdoor boiler. This way, the pump remains primed and operates normally.
Myth 4: Daisy-Chaining Pumps is Useless
Myth: Daisy-chaining pumps are an archaic and obsolete way of boosting flow.
Reality: This is actually one of the best ways to increase your flow strength through an outdoor boiler system by daisy chaining two 1/6 HP circulator pumps. Daisy chaining refers to using two pumps in series to enhance fluid circulation all through the loop. With such a setup, you ensure that both pumps complement each other and that the power to support every pump is perfect for consistent flow. And, as a matter of fact, it is the only technique that manufacturers and hydronic heating specialists recommend for an improved performance.
Myth 5: Analyzing your System Before choosing a Pump is Not Necessary
Myth: Users often choose a pump based on general recommendations without making an assessment of the heating requirements.
Reality: You must size your system before you choose a pump. The amount of bottlenecks and the distance from the boiler to the building could help determine the type and size of pump you’ll need. Over 95% of sizing data reflects that the 1/6 HP pump will suffice for most applications, but proper sizing will ensure you get the one correct fit for your particular situation.
Conclusion
Understanding the real facts about circulator pumps for outdoor boilers would mean proper maintenance of a highly efficient heating system. By dispelling these common myths, you can make more informed decisions that can better enhance performance and prolong its working life in your outdoor boiler.Investing in the right pump and proper installation will ensure that your heating system is running efficiently and keeping your home warm and cozy.
