Tankless vs. Storage Water Heaters for Ontario Homes

Tankless Water Heaters

Tankless water heaters provide hot water on demand without storing it in a tank. These systems are compact and can be a good option for homes looking to reduce ongoing energy use, and our tankless water heaters in Oakville are carefully sized to handle Ontario’s colder incoming water temperatures.

Storage Water Heaters

Storage water heaters keep a set amount of hot water ready for use in an insulated tank. They are a common choice for Ontario homes, offering reliable performance in cold weather and consistent hot water for households with higher or simultaneous demand.

For Ontario homes, proper sizing and installation are key, especially in colder months when incoming water temperatures are lower. Both tankless and storage tank water heaters can perform well when matched to household usage and climate conditions.

Storage Tank Water Heaters

Storage tank water heaters store water in a tank so that hot water is available at any time in the house. These can be heated with electricity, gas or oil.

The new efficient models can perform as much as 40% better than older models. Say goodbye to traditional hot water tanks, Oakville. Say hello to modern, European efficiency.

These are various types of water tanks we deal with:
High-recovery storage water heater
Power vented water heater
