A Smart Add-On to Boost Boiler Efficiency by 15% or More
If an older boiler drives your heating system, there's a good chance you can achieve greater efficiency by augmenting the appliance with an outdoor reset control. Affordable and easily installed, the technology ensures that you spend no more than necessary to keep your home comfortable throughout the winter months.
This time of year, homeowners around the country bemoan the high cost of home heating and naturally seek out ways to reduce their costs. A point of frustration is that, while there’s no shortage of energy-saving measures to pursue, many offer only a modest payoff in relation to the amount of time or money required to put them into effect. That said, if yours is a hydronic heating system, you have a simple, affordable, and highly effective option at your disposal. Install an outdoor reset boiler control, and you can ensure that you spend no more than necessary to keep your home warm throughout the winter season.
To appreciate the value of the device, remember that hydronic systems are designed to output enough heat to compensate for the heat loss incurred on the coldest days of the year. Most of the time, however, temperatures are not so extreme, making it unnecessary for the boiler to run at maximum capacity. But while newer boilers are capable of self-regulating, but the typical older model “fires at full blast, even if it’s 50 degrees outside,” according to Daniel O’Brian, a technical specialist with SupplyHouse.com. That means, O’Brian continues, “You may be wasting a lot of money on heating that your home doesn’t really need.”
When the alternative is to purchase a new boiler, many homeowners choose instead to install an outdoor reset control. The latter costs only a few hundred dollars, but works to make any existing, traditional boiler considerably more energy efficient. How? By means of a discrete, electronic sensor positioned on the home exterior, the device actively monitors the outdoor temperature. Then, based on its reading, a microprocessor calculates the heating demand and adjusts the performance of the boiler accordingly. That way, the boiler never runs harder or for longer than necessary to achieve the desired indoor temperature.
“Outdoor reset controls save money and increase comfort; it’s as simple as that,” O’Brian says. On the one hand, by modulating the boiler, the device increases the efficiency of the appliance by at least 15 percent, saving the homeowner no small amount on month-to-month utility bills. On the other hand, it leads to a more pleasant living environment by eliminating the dramatic temperature swings that inevitably occur in any home whose boiler goes back and forth between inactivity and full-capacity operation. “There’s a good reason why newer boilers have outdoor reset control technology built-in,” O’Brian points out.
Among the outdoor reset controls on the market, different models come with different features. For instance, some include an automatic boiler differential function, which helps homeowner save even more by preventing the heating system from short-cycling—that is, operating in inefficient bursts—when there’s a low level of heating demand. Others feature a “warm weather shut down” mode, which turns off the boiler on unseasonably warm days, when the outdoor temperature rises above a certain preset threshold point. The value of such features, O’Brian says, “depends on your needs and the climate where you live.”
The experts at SupplyHouse.com are always on hand to help homeowners choose the right product, but it’s important to note that installation is best left in the hands of professionals. Even if you’re a veteran home handyman, “there are a lot of variables to consider during installation, and any oversights can pose serious problems for the performance of your heating system or cause permanent damage to the boiler.” For homeowners, O’Brian concludes, it’s best to concentrate on the results of an outdoor reset control installation. “Compare your bills before and after,” he says. “You’ll like what you see.”
