Tankless Water Heater Installation, Repair & Maintenance in Coquitlam
A tankless water heater delivers hot water on demand instead of storing and reheating a tank of it around the clock, which means lower energy bills and no more running out mid-shower. KC's Plumbing, Heating & Drain Services installs, repairs, and maintains tankless systems across Coquitlam and the Tri-Cities.

Why Homeowners Choose Tankless
- Lower energy costs. No standby heat loss from keeping a tank of water hot all day.
- Unlimited hot water. No tank to run dry mid-use.
- Less space required. Wall-mounted units free up floor space a tank would take up.
- No sediment buildup. Capacity never shrinks the way it does in a storage tank.
The trade-offs are worth knowing too: tankless units cost more upfront, output can dip slightly if multiple fixtures run at once, and they need electricity or gas to function, so they won't provide hot water during a power outage the way some tank systems briefly can. We'll walk you through whether the trade-offs make sense for your household.
Common Tankless Water Heater Problems
- Error codes or shutdowns. Often scale buildup or a flow sensor issue.
- Cold water mid-shower. Can mean the unit is undersized for simultaneous use, or a component has failed.
- Reduced flow. Usually scale restricting the heat exchanger.

Why Maintenance Matters More Here
Tankless units skip the sediment problem tank heaters have, but they're not maintenance-free. Much of the Lower Mainland has soft water, and while that's easier on pipes overall, mineral scale can still build up inside the heat exchanger over time and reduce efficiency. We recommend annual descaling to keep the unit running the way it's meant to. Our tankless maintenance guide covers what that involves.

Converting From a Tank
Switching from a storage tank to tankless is a real conversion, not a simple swap, and typically involves gas line sizing, new venting, and sometimes electrical work. We'll assess your home's hot water demand, count your fixtures, and size the right system, including whether a single whole-home unit or point-of-use units in specific locations makes more sense for you. Our tankless installation guide covers the process in detail.

How Often Does a Tankless Unit Need Maintenance?
Annual descaling is the general recommendation, especially given the mineral content in Lower Mainland water.
