May 31^st marks the end of the “Heat Season,” for building owners in New York City to provide heat to tenants until October 1^st.  This should also mark the period to begin repairing, tuning up, or replacing boilers and radiators in the multifamily buildings throughout the city.  One of NYC tenants’ major complaint, beside very little heat in a city apartment, is an overheated apartment!  Some apartments are so hot that it kills house plants and tenants resort to desert plants! New Yorkers’ solution to overheated apartments for years has been to open up their windows, to release some of the heat trapped in their apartments.  Many of these buildings are overheated simply because they have a hard time ensuring that every apartment is heated.  So some apartments in the same building might be overheating while other apartments might just have enough heat to comply with the City Housing Maintenance Code and State Multiple Dwelling Law.

There are solutions for these old apartment buildings that have problems with overheating by their water or steam radiators.  One consideration could be the installation of thermostatic radiator valves (TRVs) on every radiator in the building.  Most TRVs do not require electricity, are easy to install by almost any handy person, and can cost as little as $40 to $50 each.  TRVs have a built-in sensor that opens and closes the radiator according to the temperature in the room, providing an individualized comfort control to any room.

TRV is a proven technology that has been around since the mid 1940’s.  TRV has been put to test in a demonstration project in 1995 here in NYC, by the New York State Energy Research and Development Authority (NYSERDA) Report No. 95-14, Titled: Thermostatic Radiator Valve (TRV) Demonstration Project Reference No. PB96-198163.  The report concluded that “overheated apartments achieved energy savings through the installation of TRVs.”    Since the report was written in 1995, the savings associated with fuel cost might be even greater today making the simple payback period even shorter.

Other maintenance tips that apartment building owners and management can do to their boiler heating systems are:

• Clean boilers and radiators
• Tune boilers
• Replace leaking radiator vents and steam main vents
• Insulate bare piping
• Reduce domestic hot water at a constant minimum temperature of 120º degrees Fahrenheit to prevent scalds and save energy (check local codes for specific temperatures)
• TRV temperature should be set at 70º degrees Fahrenheit

The best thing about TRVs is that the investment made to control radiator heat pays for itself in the long run through energy cost savings.  It also provides a comfortable apartment temperature.
