Determining Whether Tankless Is Suitable For Your Home
Evaluate Simultaneous Hot Water Demand
Tankless water heaters are selected according to the amount of hot water the household requires at one time rather than by storage capacity. Running multiple showers, washing machines, dishwashers and faucets simultaneously increases the required flow rate, making it important to calculate peak household demand before selecting a unit. Proper sizing helps ensure the appliance can maintain the desired outlet temperature during periods of high usage.
Consider The Home's Natural Gas Capacity
Gas-fired tankless water heaters commonly require significantly higher BTU input than conventional storage tanks, with many residential models ranging from approximately 150,000 to 199,000 BTU/h. Before installation, the home's gas meter, gas piping and regulator capacity should be evaluated to confirm they can safely supply the appliance while supporting other gas-fired equipment operating at the same time.
Understand The Benefits Of On-Demand Water Heating
Because water is heated only when needed, tankless systems eliminate standby heat losses associated with storing hot water in a tank. They also provide continuous hot water for extended use, provided the household's demand remains within the appliance's rated flow capacity. These operating characteristics make tankless systems well suited to many households seeking improved energy efficiency and uninterrupted hot water.
Confirm Installation Space & Service Access
Tankless water heaters are wall-mounted appliances that occupy considerably less floor space than storage tanks, but they still require adequate clearances for servicing, combustion air where applicable, venting connections and access to isolation valves and flush ports. Evaluating the installation location before work begins helps ensure the appliance can be safely maintained throughout its service life.
Sizing Tankless Output For Winnipeg Incoming Water Temperatures
1. Calculate The Required Temperature Rise
Tankless water heaters are sized according to both the desired flow rate and the temperature rise they must produce. Temperature rise is the difference between the incoming cold water temperature and the target hot water temperature delivered to fixtures. Winnipeg's groundwater is considerably colder than in many other regions, so tankless systems must work harder during winter to achieve the same outlet temperature.
2. Match Flow Rate To Household Fixtures
Every plumbing fixture contributes to the home's peak hot water demand. Showers commonly require approximately 1.8–2.5 gallons per minute (GPM), while faucets, dishwashers and clothes washers add additional flow requirements when operating simultaneously. Adding these demands together helps determine the minimum flow rate the selected tankless water heater should be capable of producing at the required temperature rise.
3. Understand Modulating Burner Performance
Modern gas-fired tankless water heaters use modulating burners that automatically adjust their firing rate according to the household's current hot water demand. Instead of operating only at full capacity, the burner increases or decreases its BTU output to maintain a more consistent outlet temperature while improving fuel efficiency during periods of lower demand.
4. Select A Unit Based On Real Winter Performance
Manufacturer performance charts illustrate how flow rate changes as the required temperature rise increases. Because Winnipeg's incoming water temperatures can approach 2–5°C during colder months, selecting a tankless unit based only on warmer-weather performance may result in insufficient hot water during winter. Reviewing the appliance's cold-water performance data helps ensure reliable year-round operation.
Preparing Gas, Venting & Condensate Connections
- Install Gas Piping Sized For High BTU Demand
Tankless water heaters typically require substantially larger gas supplies than conventional storage tanks because of their high firing rates. Gas piping is sized according to the appliance's BTU input, total pipe length and the cumulative demand of all gas-fired appliances connected to the system. Proper gas-line sizing helps ensure the unit receives sufficient fuel while operating at full capacity.
- Install Approved Venting Systems
Most modern condensing tankless water heaters use sealed direct-vent systems that draw combustion air from outdoors and discharge combustion gases through dedicated vent piping. Vent materials, pipe diameter, equivalent vent length and terminal clearances must comply with both the appliance manufacturer's instructions and applicable gas installation codes to ensure safe, reliable operation.
- Provide Proper Condensate Drainage
High-efficiency condensing tankless units extract additional heat from combustion gases, producing acidic condensate as a by-product. This condensate must be discharged through an approved drain connection, and many installations incorporate a condensate neutralizer to raise the pH before disposal. Proper condensate management helps protect drainage piping and supports long-term appliance performance.
- Install Isolation Valves & Flush Ports
Most professionally installed tankless systems include service isolation valves with integrated flush ports. These valves allow the heat exchanger to be isolated from the home's plumbing system for future descaling and servicing without shutting off water to the rest of the house. Incorporating these components during installation simplifies maintenance and helps preserve the efficiency of the heat exchanger over time.
Tankless Water Heater Installation FAQs
How is a tankless water heater sized?
Tankless water heaters are sized using two primary factors: the maximum hot water flow rate required by the household, measured in gallons per minute (GPM), and the temperature rise needed to heat the incoming cold water to the desired outlet temperature. Both calculations are essential to selecting a unit that can maintain consistent hot water during peak demand.
Why do Winnipeg homes require larger tankless units than warmer climates?
Winnipeg's incoming groundwater temperature is much colder, particularly during winter, often ranging between approximately 2°C and 5°C. Because the appliance must produce a greater temperature rise than in warmer regions, the available hot water flow rate decreases unless a larger-capacity unit is selected.
What is a modulating burner?
A modulating burner automatically adjusts its gas input to match the household's changing hot water demand. Instead of operating only at maximum output, it increases or decreases the firing rate to maintain a consistent outlet temperature while improving fuel efficiency during periods of lower water usage.
Why are isolation valves and flush ports installed?
Isolation valves allow the tankless unit to be separated from the home's plumbing system, while integrated flush ports provide convenient connections for circulating descaling solution through the heat exchanger. These components simplify future servicing and help maintain efficient heat transfer in areas with mineral-containing water.
What is a condensate neutralizer?
High-efficiency condensing tankless water heaters produce mildly acidic condensate during normal operation. A condensate neutralizer contains media, typically limestone or similar alkaline material, that raises the pH of the condensate before it enters the building's drainage system, helping protect drain piping from long-term corrosion.
How long can a properly maintained tankless water heater last?
A professionally installed gas-fired tankless water heater commonly provides 20 years or more of service when properly maintained. Periodic heat exchanger flushing, regular inspection of venting and combustion components, and servicing according to the manufacturer's recommendations all contribute to maximizing the appliance's lifespan.
