Hot Water Rules

Did you know that water heaters can consume up to 25% of your home’s energy use? That’s more than any other system besides your furnace. If your energy bills have been steadily climbing, don’t blame it on the family members who daydream in the shower—it might actually just be time to replace the tank. 

Rümi carries a variety of water heaters, from standard natural vent models to power vented options. We also carry eco-friendly tankless water heater systems that are both kind to the environment and to your wallet.

Bradford White is the primary conventional hot water tank brand we work with, but we do install and repair all major brands. 


Standard Atmospheric vs. Power Vent Options 

Atmospheric vent water heaters are simple and don’t require electric power or moving parts, while power vent water heaters use a fan to push the excess gases through the venting pipes and outside.  


Atmospheric Venting 

If you look at your current water heater and see a metal pipe rising from the top, you most likely have an atmospheric vent. With this system, fuel is heated to warm the water. The pressure of the combustion pushes excess gas upwards and out your chimney. 

No electricity is needed for venting, so the water will heat even if the power goes out. This simple venting structure is often found in older homes as it’s easy to replace and is often the least expensive choice. There are, however, a couple of reasons to consider an alternative venting method. 

  1. Enough heat has to remain in the atmospheric venting tank to effectively make the gases rise. This means that some of the fuel burned does not go to heating water, but instead rises upward and out the chimney with the gases. This wastes energy and money.  
  2. Built-up gases can pose a potential safety hazard. Therefore, older heating tanks must be tuned-up on a strict regular schedule. 


Power Venting 

Power vents use a fan to push the excess gases through the venting pipes and outside. Because they use a fan, the gases are not as hot as those in older tanks, and a lighter, plastic pipe can be installed. 

Power venting heaters are more energy efficient, because all the fuel that’s used goes to heating the water, unlike in an atmospheric venting model. Fans also create more consistent pressure to push dangerous gases out of your home. 

The one drawback to power venting is that it’s more difficult to install and therefore requires a bigger investment up front.

Our Process

In-home Assessment: Rümi’s home comfort advisors take note of the number of bathrooms, kitchens, and laundry rooms in your property and determine just how much water your household uses before we recommend a hot water tank. 

Sound advice: We offer unbiased advice on brand options and suggest a water heater that fits your unique requirements.

Installation: A water tank technician will safely remove and dispose of the old tank and replace it. Our team follows manufacturer’s guidelines on every water heater and makes sure the system works efficiently before they consider the job complete. 


Why Rümi? 

Rümi’s roots stretch back 70+ years as part of the ATCO family. We are well-established and we aren’t going anywhere. While smaller companies may sometimes be able to provide lower quotes, consider the real price you’ll pay if they’re not around in five years when you need something repaired under their warranty. Rest assured that Rümi will still be here. 



Tankless water heater installation

Go Tankless 

The standard water heater was invented in 1870. Times have changed, and maybe it’s time you changed your water heating system, too. 

Tankless water systems take up less space, are more efficient, and provide a continuous supply of hot water. Conventional systems can run out and leave you waiting around for more of the good stuff. 

Rümi carries a variety of tankless water heater brands, including: Rinnai and Noritz. 


Is it Time to Go Tankless? 

Enjoy endless hot water and put an end to rationing showers, dishwashing, laundry and more. Our tankless hot water heaters have two stainless steel heat exchangers that resist corrosion and scale buildup better than other materials, thereby boosting system life. 

Engineered expressly for the North American residential market, our high-efficiency, condensing tankless water heaters are designed to cut installation time and cost when replacing larger, storage tank-type units.  

Tankless water heaters also give you back your space. Only the size of a small suitcase, our wall-mounted models can be installed in compact spaces in both indoor and outdoor locations. They take up less space for heating, giving you back more space for living. 

Having hot water whenever your family needs it shouldn’t be a luxury. No more disputes over who gets to use the shower first. Now your family can enjoy an endless supply of hot water. Two showers running at once? No problem. Laundry and dishes at the same time? Great idea. Thanks to our innovative technology, your family’s comfort and convenience come first. 

Save on energy while boosting your home’s value. Welcome to ultimate efficiency. With technology that operates only when hot water is needed, super-efficient heating coils, no pilot light and no storage tank to heat and reheat water, you save on energy and utility costs. In fact, Our Tankless Water Heaters use up to 40% less energy than a traditional tank water heater. Plus, with premium technology, increased energy efficiency, an improved Home Energy Rating System (HERS) Index Score, and optimized LEED eligibility, our tankless solutions can increase your home’s value. You can even qualify for energy efficiency rebates and tax credits. It’s a smart investment for now and the future. 


Wi-Fi technology 

Available as an added feature, the Tankless Water Heaters take control and flexibility to a new level. Now you can control your hot water from anywhere in the home with an easy app that you control from your smartphone. 

Pro Tip: If you have a tankless water heater, a water softener is highly recommended. Without one, a yearly service and flushing is a must!

  • When to Replace a Hot Water Tank?

    Tanks that are more than 10- to 12-years-old lose efficiency as they start to breakdown. You may find that between higher energy bills and costly repairs, it could actually be more cost efficient to simply replace the outdated tank. 

    No homeowner dreams of waking up to a flooded basement on account of a busted tank. To avoid unwelcomed drama, consider a Rümi virtual home check-up to determine the lifespan that’s left in your tank. 

    It’s time to replace the tank if your water heater is: 

    • Leaking 
    • Producing dirty water 
    • Running out of hot water more quickly than it used to 
    • Showing signs of corrosion or rust 
    • Producing foul-smelling water

  • Is a Tankless Heater Right for You?

    For homes that use 41 gallons or less of hot water daily, demand water heaters can be 24–34% more energy efficient than conventional storage tank water heaters. They can be 8–14% more energy efficient for homes that use a lot of hot water—around 86 gallons per day. You can achieve even greater energy savings of 27–50% if you install a demand water heater at each hot water outlet. 

    The initial cost of a tankless water heater is greater than that of a conventional storage water heater, but tankless water heaters typically last longer and have lower operating and energy costs, which could offset its higher purchase price. Most tankless water heaters have a life expectancy of more than 20 years. They also have easily replaceable parts that extend their life by many more years. In contrast, storage water heaters last 10–15 years. 

    Tankless water heaters can avoid the standby heat losses associated with storage water heaters. However, although gas-fired tankless water heaters tend to have higher flow rates than electric ones, they can waste energy if they have a continuously burning pilot light. This can sometimes offset the elimination of standby energy losses when compared to a storage water heater. In a gas-fired storage water heater, the pilot light heats the water in the tank, so the energy isn't wasted. 

    The cost of operating a pilot light in a tankless water heater varies from model to model. Ask the manufacturer how much gas the pilot light uses for the model you're considering. If you purchase a model that uses a standing pilot light, you can always turn it off when it's not in use to save energy. Also consider models that have an intermittent ignition device (IID) instead of a standing pilot light. This device resembles the spark ignition device on some gas kitchen ranges and ovens.
