Tankless Water Heater Rinnai Rental Packages

This is the first time any sales person was so cooperative from the time looking for water heater till the time it gets installed he was walking with me.I will definitely recommend and do business again in future.

I used this company for my hot water tank installation. They were cheaper then my existing plan, offered me great incentives, and were extremely responsive. I’d been out of hot water for almost 1 week and when I called they replaced my tank the next day. Abdul was such a pleasure to work with. Great experience! Would definitely recommend them.
Our furnace stopped working and we contacted HVAC ontario for a quote on a new furnace. Their advisor was at our home within a few hours. He explained everything in detail . We purchased our new heating and cooling system from HVAC Ontario.

Who should I be get my water heater from?

There are many different options when it comes to rental water heaters i.e Reliance rental water heates, Enercare water heater rental, Vista, and chuck with the truck. We recommend discussing your options with a certified HVAC contractor to find out the best solution for you.

What size of tankless water heater do I need for my home?

Installing a wrong sized tankless water heater at your home can be costly and uncomfortable.  An oversized tankelss system will shut down more often resulting in rapid cycles that will cause an increase in furnace breakdowns.

A smaller sized tankess will constantly operate and try to maintain the desired temperature in your home, leading to frequent system failures and cold showers.

Be sure to get a properly sized tankless water heater that is based on your home needs to ensure that your tankless runs to its maximum efficiency throughout the day.

Who is Reliance Home Comfort?

Reliance Home Comfort is a residential services company in Canada primarily focused on rental, sales and maintenance of water heaters and heating, ventilation, and air conditioning systems. The company has its largest base of operations in Ontario, but also has offices in western Canada.

Reliance has its origins in the storage water heater rental business formerly owned by natural gas utility Union Gas, which served much of Ontario.[2] Reliance’s main Ontario competitor, Enercare, has a similar origin as the rental business of Toronto-area utility Consumers’ Gas.[3] (The utility operations of both Union and Consumers’ are now part of Enbridge.[4][5])

Beginning in the mid-20th century, Ontario gas providers such as Consumers’ and Union would work with home builders to pre-install gas-powered water heaters, which the providers would agree to subsidize and maintain in exchange for a monthly rental charge on each homeowner’s gas bill.[3] This practice of renting water heaters, as opposed to purchasing them, became widespread in Ontario, but is not common elsewhere in Canada.[6][7]
