Simple Guide for Choosing the Most Efficient Boiler Systems for Apartment Buildings

For quite some time, boiler systems for apartment buildings were limited to large traditional hot water boilers. Although effective, these boilers can take up a significant amount of space and be very cumbersome.

Most importantly, these large types of boiler systems can be extremely inefficient in regards to hot water delivery and energy consumption. This regularly leads to complaints from tenants about the limited availability of hot water and spiked utility bills — both of which tend to worsen as the boiler ages.

A few years ago a new heating and water-heating boiler system for apartment buildings emerged and has become more prevalent in the U.S. This multifamily boiler system is the high-efficiency wall-hung or floor condensing boiler.

The versatile condensing multifamily boiler is uniquely designed to save space and minimize utility bills while continuously providing hot water and heat to tenants. Continue reading to learn more about the condensing boiler and why it's quickly becoming the premier choice for heating and hot water systems for apartment buildings.

What Is a Condensing Boiler?

The condensing boiler achieves high efficiency through the capture of latent heat from the exhaust gases. The boiler then uses this heat to effectively preheat incoming water. This exceptionally efficient transfer process results in very little heat lost or expelled through the venting system.

As a result, the temperature of the exhaust gas falls below the dew point, which causes water vapor in the exhaust to condense into a liquid. Condensing boilers can usually achieve an annual fuel-utilization efficiency (AFUE) of 90% or higher and are usually gas fired. Due to the size and lightweight nature of many condensing boilers, they're able to be hung onto walls, which empower the more efficient use of floor space.

Heating-Only Boiler Systems for Apartment Buildings

Heating-only condensing boilers offer a central-heating, closed-loop option ideal for apartment buildings and multifamily use. On the other hand combi boilers (water-heating and heating boilers) are uniquely engineered with a closed loop for central heating and an open loop to provide domestic hot water.

Because of this, combi boilers can serve high-efficiency solutions for both a central heating system and on-demand water heater. By installing a single combi boiler in each apartment, owners can individualize utilities for tenants.

Benefits of Multifamily Condensing Boilers

High-efficiency condensing boilers offer a vast range of high-performance water-heating and heating benefits for today's multifamily property. Some of the most common benefits are listed below.  

Individualized Utilities

The smaller size and energy efficiency of condensing boilers and wall-hung condensing boilers allows facility managers and property owners to individualize utilities. Each unit or apartment will be served by its own boiler and have an individual thermostat. You can install the boilers inside each apartment, separately, or in a central location like the basement.

When you individualize, you'll pass the responsibility for the utilities to each tenant. This means you'll no longer be responsible to pay the building's entire heating bill, which can be a huge selling point for potential tenants because they retain control over the temperature in their home instead of just accepting the overall consensus presented by the central boiler system.

Lower Utility Bills and Improved Efficiency

In comparison to traditional hot-water boilers, today's condensing boilers are significantly more energy efficient. Condensing boilers can reduce utility bills for tenants and building owners. For instance, condensing boilers can have an AFUE rating of up to 96% while traditional hot-water boilers average around 80%.

Saving Space

With a condensing boiler that is wall hung, you can free up valuable floor space. Even if you choose a floor model boiler system for your apartment building, condensing units are  traditionally much smaller.

For instance, the Weil-McLain SlimFit Commercial Condensing Boiler offers a lightweight, compact design with a shipping weight of less than 550 lbs. and a short width of only 18 inches. The SlimFit is ideal for retrofits or replacements with narrow hallways, small elevators, and difficult access to mechanical room.

Longer Equipment Life

Some high-efficiency condensing boilers feature down-fired ceramic burners, which work to ensure any exhaust condensation is quickly captured and diverted to a drain. In more traditional units with the bottom-up burner configuration, any exhaust condensation can navigate back into the unit to damage the heat exchanger or drop on the burner system. Condensing boiler systems can be easier to service and maintenance, which can further extend of the life of the unit.
