A tankless water heater gives a house hot water that never runs out, and in a small home that is all it needs to do. In the large houses on Heritage Mountain and in Heritage Woods, and in the renovated homes with a suite in Glenayre and College Park, there is a second consideration: how long the hot water takes to arrive. The unit is usually in the garage or the mechanical room on the lowest level, and the shower it serves can be 20 metres of pipe away on the top floor. The water sitting in that pipe has to clear before the hot arrives. A recirculation system solves it by keeping hot water moving through the line. Some of these homes have one, built into the heater or added as a separate pump under the farthest sink. When it fails, the symptom is the same slow hot water the system was installed to cure. A tankless water heater repair call in one of these homes often starts with the pump, the timer, or the sensor that runs it rather than the heater itself.
The heaters themselves are a mixed group. Many of the tankless units in Port Moody's 2000s homes are first-generation non-condensing Navien, Rinnai, or Takagi units, now 10 to 20 years old. The parts that fail on them are the igniter, the combustion fan, the flame rod that detects the burner is lit, the flow sensor that turns the unit on when a tap opens, and the water valve that sets the temperature. All of them are repairs. The condensing units installed in the last ten years add a condensate line and a second heat exchanger. The calls on those are mostly error codes, which the control board records and we read at the start of the visit. We service Navien, Rinnai, Takagi, Noritz, Bosch, Rheem, and every other residential brand.
The diagnostic starts at the display, because a modern tankless heater keeps a log of every fault. From there we check the flow through the unit, the temperature at the inlet and the outlet, the ignition sequence, the combustion fan, and the venting. Where the home has a recirculation system, the pump and its controls are part of the check. The repair is quoted as one price before the work starts, and we carry the common parts on the truck. Eaton's Heating is TSBC licensed (LGA0200006), a Home Performance Contractor Network member, and holds a 4.9 rating across 400-plus Google reviews.
A tankless heater that is 15 or 20 years old gets one question first: whether a repair is still worth making. When it is, we make it. When it is not, we lay out the replacement options with real prices on the same visit. The same goes when the heat exchanger has started leaking, when parts for the model are no longer available, or when the unit is too small for the household it now serves. We install Navien and Rinnai, including the models with recirculation built in. Our Port Moody HVAC services cover the tankless heater and the furnace or boiler it shares the mechanical room with, and any of them can be booked for the same day.
A new tankless water heater from Navien or Rinnai gives a Port Moody home hot water that does not run out, from a unit that hangs on the wall. It heats only the water you use instead of keeping a tank hot around the clock. The current condensing models pull more heat out of the exhaust than the first-generation units did, so the gas bill for hot water drops. The models with a recirculation pump built in bring hot water to the top floor of a large home without a separate pump under a sink. We install both brands and size the unit for the household, so a home with a suite gets a unit that keeps up.
The most common installation we do is a straight replacement of a tankless unit that is 15 or 20 years old, onto the venting and gas line already in place. That is usually a one-day job. The other is a switch from a hot water tank to tankless, which frees the floor space the tank took and gives the household hot water that does not run out. That job needs a look at the venting and the gas line before it is quoted. Either way it starts with a free estimate and a written quote. The hot water heaters we install come with the manufacturer's warranty, which we register on your behalf so the full term applies.

Same-day service available, and the phone is answered around the clock. A tankless heater that has shut down leaves the house with no hot water at all, so call as early in the day as you can. If the unit is in the garage or a mechanical room with a separate entrance, let us know when you book.
Every residential brand. We service Navien, Rinnai, Takagi, Noritz, Bosch, Rheem, and the rest, and we carry the common parts on the truck. Anything else is ordered as needed. Everything we install is OEM and CSA certified with six months of warranty on parts and labour.
A tankless heater fires only when enough water is flowing through it, and that threshold is called the minimum flow. A shower running at a low setting, a low-flow shower head, or a tap barely open can drop below it, and the unit shuts off, lets cold through, then fires again when the flow rises. Sometimes the cause is the fixture, and sometimes it is a flow sensor or a scaled heat exchanger inside the unit. The diagnostic sorts out which.
Yes, over time, though less often than in most places. Port Moody's water comes mostly from the Coquitlam reservoir and is soft, so scale builds slowly. It still builds, and a heat exchanger that has scaled runs hotter than it should and delivers less. Descaling is a standalone service, and on a unit that has never had it done, it is worth doing. It is not part of the diagnostic, and it is booked as its own visit.
The diagnostic is $189 and covers the unit, the water and gas connections, the venting, and the recirculation system where there is one. Every repair is then quoted as a fixed price before the work starts. Parts on a tankless heater vary widely by brand and by the part, so we do not guess at them over the phone. The number comes from the technician looking at your unit.
Often, yes, and especially in a house with a suite or a family that runs out of hot water in the morning. A tankless unit never runs out, takes up no floor space, and costs less to run because it is not keeping 40 gallons hot all day. It costs more to install than a tank, and the venting and gas line have to suit it. The free estimate confirms both. If your household is small and the tank has served it fine, a new hot water tank may still be the sensible choice, and we will say so.
