If you are experiencing condenser overheating, it may be time to take your system in for repair. This is something that can become a regular occurrence when water heaters are operated at a high flow rate. Depending on the temperature of the water and the flow rate that the water heater is operating at, a condenser will produce quite a bit of heat. However, this heat has to go somewhere. Most people don’t realize that the exhaust from their condenser is where the heat is going, even if they are sitting next to the unit and are using it.
The exhaust from your water heater will contain the heat generated by the water. It is important to look closely at the back of your water heater to determine which area of the system is where the heat is escaping. If you are experiencing condenser overheating in this area, it is time to have it looked at. Many units have a thermostat that controls the flow of exhaust from the condenser and can be set at a higher flow rate than normal.
If you continue to have condenser overheating problems, increasing the flow rate may not solve the problem. Instead, you should try increasing the temperature of the water that is flowing out of the unit. Cold water takes longer to come out of the condenser, and if you have a low flow rate that is operating at the proper temperature, you can increase the speed of the flow to try to get the same results as if the unit was operating at a higher flow rate. You may also want to consider installing a thermostat in the unit.
