Tankless service for household hot water
Tell us whether you need help with inconsistent hot water, an error code, planned maintenance or replacing a storage tank with an on-demand system. A brand, model and service history are helpful if available.
We assess the symptoms and installation before recommending maintenance, repair or replacement.
If you suspect a gas leak, leave the area immediately. Do not use a phone, electrical switches or other ignition sources in the area. Once outside, call FortisBC at 1-800-663-9911 or 911. Do not wait for a service callback.
Common reasons to call
- No or inconsistent hot water
- Error codes
- Scale-related performance loss
- Planning a tankless conversion
Tankless service starts with the whole hot-water demand
An error code is useful, but it is only one part of the diagnosis. Water flow, inlet filters, scale, fuel supply, venting, condensate and simultaneous demand can all affect how an on-demand water heater performs.

The exact check depends on the equipment, access and approved service scope.
Maintenance, repair or a new tankless system
Routine service helps manage filters and scale where applicable. Repair may resolve an isolated control or component fault. For a new installation or tank-to-tankless conversion, available utilities, venting and peak hot-water demand need to be reviewed before equipment is selected.
Before converting from a tank to tankless
- Simultaneous fixture demand and temperature rise
- Fuel capacity, electrical requirements and venting
- Condensate drainage and maintenance access
- Any recirculation or hot-water delivery requirements
Inconsistent hot water: one fixture or the whole home?
If one shower goes cold while other taps stay hot, the fixture’s flow or hot-and-cold mixing may be part of the problem. A tankless heater also needs enough water flow to operate. These are clues for diagnosis, not proof that the heater needs replacing.
If temperature or flow changes when showers, taps or appliances run together, the assessment compares that simultaneous demand with the heater’s capacity and the temperature rise it must provide. An error code or a problem affecting every fixture calls for review of the heater and its supplies as well.
Note where the problem occurs, what else is using hot water and any visible code. Leave covers and gas or electrical components alone; share what you can observe safely when requesting service.
Tankless diagnosis and service-call fee
The tankless service-call fee is $189.99 plus 5% GST. Tell us whether you need help with a fault, planned maintenance or a conversion assessment so we can confirm the requested scope. The fee remains payable if you decline the repair.
If the serviced tankless unit is found to need replacement, the service-call fee is credited when High Demand Heating completes the replacement.
Maintenance and flushing are different parts of the visit
Flushing addresses mineral scale inside the water heater. Maintenance can also include inlet-filter care and review of operation, venting, condensate and accessible connections, as applicable to the model. A flush alone does not diagnose every cause of inconsistent hot water.
The manufacturer’s instructions, water conditions, service history and current symptoms guide the work and interval. Tell us when the unit was last serviced or flushed if known, and ask which maintenance tasks are included in the proposed visit.
What affects a tank-to-tankless conversion quote?
Converting from a storage tank can involve more work than replacing an existing tankless unit. The assessment checks peak hot-water demand, gas-supply capacity for a gas unit, electrical requirements, the vent route, condensate drainage, piping and access for future service. Existing connections cannot be assumed suitable for the new equipment.
The selected equipment and required installation changes drive the quote. Ask it to distinguish the heater, installation work, any supply or venting changes, commissioning and old-equipment removal. A recirculation option, if wanted, also needs assessment; tankless alone does not remove the wait for water already in the pipes.
If the concern is cold radiators or in-floor heating rather than water at the taps, tell us: a boiler or combined system needs a different assessment.
Prepare for a tankless water heater appointment in Maple Ridge
Tell us whether the equipment is in a garage, crawlspace, attic, mechanical room or suite, and mention gates, tenant coordination or limited access. Those details help the office assign the right appointment and reduce avoidable delays.
Provide the brand, model, code and which fixtures are affected. For a conversion inquiry, say whether the home currently uses a storage tank and how many hot-water fixtures may run together.
