BOILERS & HOT WATER
He notes that the systems’ piping and panels are configured to integrate with existing equipment rooms, to reduce installation costs. In addition, advanced controls are designed to extract the maximum energy from the available electric power.
Optimising reliability and lifespan
Since building tenants rely on the electric boilers for hot water daily, investing a little more in the initial purchase can pay off dramatically in increased long- term reliability and longevity. While there are some smaller, commercial boilers in the market that will typically last from 5 to 10 years before replacement is required, Acme’s electric boilers are designed to an industrial standard that will last decades. In fact, some of the company’s electric boilers were used continuously for over 35 years before refurbishment was needed. Before selecting an electric boiler, it is essential for building managers to factor in longevity, reliability, required maintenance, and installation options. In this vein, for managers that use a hot water loop with their electric boiler, Presser recommends adding a heat exchanger to reduce exposure to pipe scale and significantly extend longevity.
Many need expert guidance on how to proceed with the conversion from gas-fired to an electric boiler like this one: including basic requirements and other factors to consider.
In this arrangement, the electric boiler would run in a closed loop system. The boiler water is treated before entering one side of the heat exchanger, and hot water for the building exits the exchanger’s other side. “Since the pipe scale and lime never touch the boiler, its elements will remain pristine. You essentially eliminate the issue of scale and lime accumulating in the bottom of the boiler. This extends the unit’s lifespan and minimizes maintenance. It is much easier to clean out a plate and heat exchanger than to dismantle a boiler and replace a heating element,” he says. Presser advises another strategy that can substantially improve long-term system reliability, which a typical contractor choosing the minimum boiler spec would not consider.
“If you have a hot water loop in the building, you can increase reliability and decrease downtime by
having an extra circulation pump on a skid ready to use in the event the first pump fails.” he says. As commercial building managers increasingly convert from fossil fuel burning to eco-friendly electric boilers to combat climate change and promote health, consulting with an expert can simplify the process, reduce total cost, and increase reliability and longevity.
Consulting with an expert can streamline the conversion to electric boilers while reducing total project cost and maximizing system reliability.
