Tankless Water Heater Installation and Repair
A tankless water heater heats the water on-demand. Since there’s no tank, the unit is not endlessly re-heating the same tank of water.
The unit may be installed in the garage, a closet, or other convenient place. It can also heat water for a single shower, sink, or appliance.
A Tankless water heater provides an endless supply of hot water. While the up-front cost is higher, your monthly utility bill will be lower.

Tankless Water Heater Repair
Sometimes a tankless water heater repair is as easy as a tankless flush. Other times the motherboard or heating element may need to be replaced.
Experts recommend doing a tankless flush every one to two years. The flush eliminates calcium build up in the unit. The flush also helps prevent a leak in the heat exchanger – the most common reason for repair.
A pro can repair your tankless water heater and keep it maintained as well.
