How to Select Low Water Cut Offs for Boilers

This article explains how to select low water cut offs for boilers. All boilers come equipped with an electronic or mechanical sensor that keeps track of the boiler’s water level. If the water in your boiler reaches an unsafe level, the cut off level alerts the system to shut down power to lessen or eliminate any damage that might a too-low water level might cause.

Check the Manufacturer’s Guide

If you have the boiler manufacturer’s informational supplement, look it over before you do anything else. It should state the recommended cut off level for your boiler. It is very useful to procure the facts straight from the source, so that you will not have to search further and wind up making wild guesses that might be incorrect.

After you’ve selected and configured the low water level cut off of your choice, you can run a test to make sure it’s the right level. Just take a screwdriver and slide it into the test opening slot of the valve to simulate a low level of water. If the cut off is working correctly, the power will shut off after you perform this action.

Troubleshooting

If you are certain you have selected the right cut off level for your boiler, but the power does not shut off at that level during the test or at another time, you probably have a problem with debris. If some sludge is lodged in the float chamber, you will need to remove it.

How to Treat a Smelly Electric Water Heater

An electric water heater is a part of many home heating solutions and systems. It is fairly reliable and lasts on average 8 to 10 years, with proper maintenance. Sometimes a water heater will start to send off smelly gases. These gases can fill up several rooms and even the whole house with time. Here are a few things you can do to treat a smelly electric water heater.

1 - Add Chlorine

You can add chlorine to the hot water heater system. To do this you will need to turn off the electricity and the water to your home. You will then need to drain off some of the excess water in the hot water heater (about 10 gallons). Once you've done that, you can pour a couple of gallons of chlorine (using pool chlorine is just fine) into your hot water heater. Before you use the hot water, you will need to drain the chlorine solution and allow it to fill up with clean water again.

2 - Replace Anode

Most hot water heaters come with a magnesium anode. These anodes sometimes are responsible for the smelly sulfur odors that are produced. You can replace this anode with an anode made of aluminum or zinc.
