Boiler Repair questions, answered by experts

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

To maintain a boiler and ensure it works optimally, regularly read the temperature and pressure gauges on the unit to ensure they're within the limits described in your owner's manual. Lubricate the circulating pump according to the manufacturer's instructions. Check the water level in the expansion tank and open the tank valve to drain it if it's more than half full.

You save money on heating oil in a few ways:

  • Make sure your home is well insulated and sealed against drafts and heat leakage.

  • Use a thermostat that’s working properly and calibrated accurately.

  • Increase energy efficiency by insulating your basement and attic.

  • Turn down your thermostat a few degrees.

  • Program your thermostat to lower the heat when you’re not home.

  • Order heating oil during the off-season when prices are likely to be lower.

Although baseboard heating is expensive to operate, hydronic style heaters usually aren’t as costly as other models because they maintain temperature longer than standard electric baseboard heaters. Since the liquid retains the heat longer, it prevents the thermostat from turning on and off as often, which makes it more energy efficient.

With proper maintenance, boilers last for around 15 years on average. A cast iron boiler may last longer, over 20 years, but you should always consider the efficiency of older boilers and opt to replace an old one if it’s significantly lower than newer, high-efficiency boilers. Otherwise, you’ll be spending more on your utility bills each month.
