Call for Tankless Water Heater Maintenance

Overtime sediment begins to build up in the system. The sediment acts as an insulator, reducing the transfer of heat from the burners to the water. The result is reduced energy efficiency and less water pressure due to a built-in “restrictor” that slows down the GPM when the water is not hot enough.

If the sediment buildup is severe enough, it can actually form chunks and flakes. These large pieces of sediment can begin inhabiting key components such as the flow sensor, affecting its ability to accurately measure GPM.

Worst case scenario? the system becomes so clogged with chunks and flakes that the unit can no longer be repaired and must replaced.

The AccuServ Team - Furnace Maintenance Toronto

Our technicians are very knowledgeable about the operation of furnaces and how to properly maintain and repair them. They go through intensive one on one courses on how to do proper safety checks, readings, measurements and most importantly, ensure the heat exchanger is not cracked. We also ensure they’re equipped with the right tools to do the job. These include:

Camera Scope: a handheld camera with a scope in order to thoroughly inspect the condition of a heat exchanger

Gas Sniffer: A highly sensitive natural gas sensor that ensures there is no gas leak in or near your furnace

Combustion Analyzer: Probably one of the most important tools, it detects if there is any CO present in the room or in the furnace. It can also be used to detect other fatal gases

Is my water heater a tankless one?

There are two kinds of common water heaters—those that heat the water in the tank, and those that operate without a tank by heating the water as it passes. If your heater uses a tank, find the information you need on this page here.

How does it work?

Tankless water heaters are preferred by some because they only heat water when needed. As soon as you turn on the shower or faucet, it kicks into gear, heating the moving water as it passes through the unit on its way to the faucet. Because the unit is not constantly on, it typically uses less energy than older hot water heaters.

Why choose a tankless water heater?

We’ve recommended a tankless water heater to customers who want to save more on their energy bills, and to those who want constant hot water that doesn’t need to be heated in a tank before it’s ready. If you’re in the market for a new water heater, we can help you choose one that’s large enough for the needs of your family and we also guarantee premium installation.
