Why A Gas Water Heater Might Become Inefficient

Posted on: 16 September 2015


Does your heating, ventilation and air conditioning (HVAC) system use hot water for heating up the house? If you have noticed that the heater is not as efficient as it used to be, it is possible that the water heater is in need of a repair. Find out in this article what can cause a gas water heater to stop being efficient, as well as what hiring a plumber to install a replacement might cost.

What Leads to a Gas Water Heater Becoming Inefficient?

An HVAC system that uses hot water for heat will stop functioning if the gas water heater is unable to send heat or steam to the radiators. No heat from a water heater is likely due to there being something wrong with the pilot. Although multiple reasons why a pilot stop working correctly, one of the most simple reasons is from it not being lit. You can take a look at the pilot to see if there is a flame present. Hire a plumber to reignite the pilot if the flame is not there and you should start getting heat from the HVAC system again.

Another cause of water heater problems is problems with the gas valve. Basically, the valve works by sending gas to the burner of the water heater so the pilot can be ignited. There is a part of the gas valve called a thermocouple that can prevent the valve from sending gas to the burner if it is damaged. Damage to the thermocouple leads to the gas valve not sensing when the pilot is in need of gas to stay lit.

Inefficiency from a gas water heater may mean that it has become old and worn out. It is possible that vital parts like the pilot and gas valve are damaged beyond repair. You will have to get a new water heater if repairs can't be made.

How Much Does a Plumber Charge to Install a Gas Water Heater?

You should be prepared to pay a minimum of $300 if you purchase a traditional gas water heater, including installation by a plumber. A traditional gas water heater can cost over $3,500 on the highest end of the scale. The gallon capacity of the water heater will be factored into the overall price.
