Question 1

What temperature should my water heater be set to?

Accepted Answer

Your water heater should be set to 60°C (140°F) for optimal safety and efficiency. This temperature kills harmful bacteria like Legionella while preventing scalding and minimizing energy waste.

Most water heaters come factory-set around 60°C, but it's worth checking yours with a thermometer at a hot water tap after running it for a few minutes. If you have young children or elderly family members, you might consider installing anti-scald mixing valves at fixtures rather than lowering the tank t

Question 2

Is a power vent water heater better than atmospheric?

Accepted Answer

Power vent water heaters are generally better than atmospheric models for most Ottawa homes, offering improved efficiency, safety, and installation flexibility, though they do cost more upfront.

Power vent water heaters use a fan to force exhaust gases out through PVC piping, while atmospheric units rely on natural draft through a metal chimney or vent. This fundamental difference creates several advantages for power vent systems. They achieve better combustion efficiency (typically 80-85% vs 6

Question 3

What is a heat pump water heater?

Accepted Answer

A heat pump water heater is an energy-efficient alternative to traditional electric water heaters that uses ambient air to heat water instead of relying solely on electric resistance elements. It works like a refrigerator in reverse - extracting heat from the surrounding air and transferring it to the water in the tank.

The system includes a heat pump unit mounted on top of a storage tank, with an evaporator coil, compressor, and condenser. The heat pump pulls warm air from your basement or uti

Question 4

Is it worth getting a water heater rental?

Accepted Answer

Water heater rentals can make sense for some Ottawa homeowners, but purchasing is usually more cost-effective long-term. The decision depends on your budget, how long you'll stay in your home, and your comfort with maintenance responsibilities.

Rental advantages include no upfront costs (typically $0 down), included maintenance and repairs, and the convenience of having someone else handle problems. Most rental companies in Ottawa charge $25-45 monthly for tank units and $45-70 for tankless sys

Question 5

Can a water heater explode if it's old?

Accepted Answer

Yes, old water heaters can potentially explode, though it's rare. The main risk comes from excessive pressure buildup when safety systems fail, particularly the temperature and pressure relief (TPR) valve.

How explosions happen: Water heaters are designed with multiple safety mechanisms, but age can cause these to fail. If the thermostat malfunctions and keeps heating water beyond safe temperatures, pressure builds inside the tank. When the TPR valve is corroded or blocked and can't release thi

Question 6

How much does a new water heater cost in Ottawa?

Accepted Answer

A new water heater in Ottawa typically costs $1,500 to $2,500 for a standard tank unit, or $3,500 to $5,500 for a tankless system, including professional installation and permits.

The price varies significantly based on several factors. Tank water heaters are the most common choice for Ottawa homes - a 40-gallon gas unit usually runs $1,500-$2,000 installed, while a 50-gallon electric model costs $1,800-$2,500. The higher-end models with better warranties and energy efficiency ratings will be t

Question 7

Why is my hot water rusty colored?

Accepted Answer

Rusty-colored hot water is typically caused by corrosion inside your water heater tank or in the hot water pipes. This is a common issue in Ottawa homes, especially with older water heaters or homes with galvanized steel pipes.

The most likely culprit is sediment buildup and corrosion inside your water heater tank. Over time, minerals from Ottawa's moderately hard water settle at the bottom of the tank, and the tank's steel lining can develop rust spots. When the water heater fires up, it stirs

Question 8

Is a tankless water heater worth it?

Accepted Answer

Tankless water heaters can be worth it for many Ottawa homeowners, but the decision depends on your household's hot water usage, upfront budget, and long-term plans. The higher installation cost is often offset by energy savings and space benefits over time.

The main advantages of tankless units include significant space savings (they mount on walls), endless hot water supply, and 15-20% lower energy costs compared to tank heaters. In Ottawa's climate, this energy efficiency becomes more valuab

Question 9

Why does my water heater smell like sulfur?

Accepted Answer

Sulfur smell from your water heater is almost always caused by bacteria in the tank reacting with the anode rod, creating hydrogen sulfide gas that smells like rotten eggs. This is more common with well water but can happen with city water too.

The anode rod in your water heater is designed to prevent tank corrosion by attracting minerals and sediment. However, certain bacteria can feed on this rod and produce hydrogen sulfide gas. This is especially common if your water heater has been sitting

Question 10

What is the best water heater brand?

Question 11

Are water heater blankets worth it in Ottawa?

Accepted Answer

Water heater blankets can provide modest energy savings in Ottawa, but their effectiveness depends on your water heater's age and location. For older tanks (10+ years) in unheated basements, you might see 5-10% reduction in heating costs, which translates to $30-60 annually on your energy bill.

Modern water heaters manufactured after 2004 already have improved insulation, making blankets less beneficial than they were for older units. However, if your tank feels warm to the touch or sits in a c

Question 12

Do tankless water heaters need yearly maintenance?

Accepted Answer

Yes, tankless water heaters absolutely need yearly maintenance to prevent mineral buildup, maintain efficiency, and extend their lifespan. Without regular maintenance, you'll face reduced performance and potentially expensive repairs.

Annual descaling is the most critical maintenance task for tankless units. Ottawa's moderately hard water (around 120-180 ppm) causes calcium and lime deposits to accumulate inside the heat exchanger. This buildup reduces heating efficiency, restricts water flow,

Question 13

How do I drain my water heater?

Accepted Answer

Draining your water heater is a straightforward maintenance task that should be done annually to remove sediment buildup and extend the unit's lifespan. Most homeowners can handle this themselves with basic tools and safety precautions.

Start by turning off the power supply - flip the breaker for electric units or turn the gas valve to "pilot" for gas water heaters. Next, shut off the cold water supply valve at the top of the tank. Allow the water to cool for several hours before proceeding, as

Question 14

Why does my hot water run out so fast?

Accepted Answer

Hot water running out quickly is usually caused by a water heater that's too small for your household's needs, sediment buildup reducing tank capacity, or a failing heating element.

The most common culprit is sediment accumulation at the bottom of your tank water heater. Over time, minerals from Ottawa's moderately hard water settle and create a barrier between the heating element and water, forcing your system to work harder while reducing available hot water volume. A 40-gallon tank might onl

Question 15

Why is my electric water heater tripping the breaker?

Accepted Answer

Your electric water heater is likely tripping the breaker due to an electrical overload, which typically happens when the heating elements draw too much current or there's a short circuit in the system. This is a safety mechanism preventing potential electrical fires or damage.

The most common causes include faulty heating elements that have burned out or developed internal shorts. When heating elements fail, they often draw excessive current, causing the breaker to trip repeatedly. Another fre

Question 16

Can I switch from electric to gas water heater?

Accepted Answer

Yes, you can switch from electric to gas water heater, but it requires significant work including running a new gas line and venting system. This conversion typically costs $2,500 - $4,500 in Ottawa, depending on your home's layout and distance to the gas meter.

The conversion process involves several major components. First, a licensed gas technician must run a new gas line from your meter to the water heater location, which can cost $800 - $1,500 depending on distance and complexity. Second,

Question 17

How much does it cost to install a tankless water heater?

Accepted Answer

Tankless water heater installation in Ottawa typically costs between $3,500 to $5,500, including the unit, installation labor, permits, and necessary upgrades. This is significantly higher than traditional tank water heaters due to the complexity of installation requirements.

The total cost depends on several key factors. The unit itself ranges from $1,500 to $3,000, with gas models generally more expensive than electric. Installation labor adds $1,500 to $2,000, but this can increase substanti

Question 18

Should I repair or replace my water heater?

Accepted Answer

The decision between repairing or replacing your water heater depends on its age, the cost of repairs, and efficiency considerations. Generally, if your water heater is over 10-12 years old and needs expensive repairs, replacement is usually the better investment.

Age is the primary factor in this decision. Tank water heaters typically last 8-12 years in Ottawa's hard water conditions, while tankless units can last 15-20 years. If your unit is approaching or past its expected lifespan, even min
