Tankless Water Heater Installation

Tankless water heaters instantly heat water as it flows through the unit. When the hot water is turned on, cold water flows through a heat exchanger, and a natural gas burner or electric element heats the water. Typically, tankless water heaters provide hot water at a rate of 2–5 gallons (7.6–15.2 liters) per minute.

The initial cost of a tankless water heater is higher than that of a conventional hot water tank, but tankless water heaters will typically last longer and have lower operating and energy costs. This can offset their higher purchase price. The other major upside of a tankless water heater is its life expectancy of over 20 years, compared to 10-15 years for a storage tank water heater.

No Hot Water

If you have no hot water in your tankless water heater, we will first check the supply of water, gas, and electricity to your unit, and that no shut off valves are closed. We will check the gas burner and ensure the flame rod produces sparks when the unit is turned on, to see if it’s an ignition problem. An error code on the control panel can often tell you what’s wrong with your unit.

Freezing temperatures or other obstructions in your pipes can also disrupt your hot water flow, so this is another important thing to test. If your water is warm, but isn’t hot enough, there may be a plumbing cross over where cold water is mixing with the hot water. If a mixing valve was installed, and it failed, this may be the root cause.

Is the gas line sized correctly for your unit? Low gas pressure can cause problems with the hot water supply. Sediment and limescale buildup on the heat exchanger can also impede the heating capabilities of your water heater.

Low Water Pressure

Low water pressure is another common issue we see with tankless water heaters. The cause of this problem is likely a blockage in the filter, water line, or fixture. We can easily determine the location of the obstruction and get your water pressure back. Sometimes, if your gas pressure is too low, the water heater will reduce its flow to meet the desired output temperature. The best way to solve this issue is to have a technician perform some diagnostic testing on your unit to find the source of the problem.

Upgrade to Tankless

If you are looking to replace your water heater with a new tankless unit, Jack will give you a free quote on installation. When we install the new unit, we will remove and dispose of the old one as well. Fortis BC offers rebates of up to $1000 when you replace your old water heater with an energy efficient model.
