SMART STEAM HEATING UPGRADES
Most steam heating systems are decades old and
haven't been updated. Outdated systems waste heat,
cause apartments to be too hot or too cold, and lead
to banging or hissing pipes.
There are cost-effective solutions to fix steam heating
systems that can save between $10,000 and $30,000*
a year on energy costs. The best approach is to
address the system as a whole.

TWO-PIPE STEAM BUILDING

2 MASTER VENTING

3 CONTROLS AND SENSORS

Add master vents to pipes. Without master
vents, air blockages in pipes prevent steam
from being distributed evenly. This causes some
apartments to get too hot, while others don't get
enough heat. Adding vents to the tops of risers and at
the ends of mains allows air out of the pipes so that
steam can fill the pipes and be distributed evenly.

Install smart boiler controls and sensors.
Most boilers operate based on the outside air
temperature, which can lead to overheating. Installing
wireless temperature sensors-and boiler controls that
communicate with them-allows the boiler to read
temperatures inside the building instead. This means
units get the right amount of heat at the right time.

End steam trap problems. Most radiators are
too big and produce too much heat. Steam traps on
radiators also break, which contributes to banging
pipes. Adding orifice plates regulates steam flow and
eliminates the need to repair steam traps.

Enable burner modulation. Most boilers can vary
their steam output to match the building's needs, but
this ability is often bypassed.

5 TRVs
Add thermostatic radiator valves (TRVs)
in apartments. Without TRVs, there's no way for
residents to turn down the heat when an apartment is
getting too much steam. Adding TRVs enables residents
to control the heat in their units.
You can also:
- Clean and tune the boiler
- Regulate and reduce pressure for steam production
- Make sure steam is dry
