Choosing the Right Water Heater

At Donaldson Heating & Air Conditioning, we know that having hot water when you want it and knowing you’ll never run out is important you. However, when deciding which water heater is right for you and your home, it’s important to know the differences between the two major types of water heaters: tank and tankless.

Types of Water Heaters

 Tankless Water Heaters

Donaldson Heating & Air Conditioning’s tankless water heaters are both an energy efficient and cost-effective solution for most homes. Tankless water heaters heat water on demand, rather than storing gallons of water. This means that you only pay for heating the water you use; no more wasted money on keeping a large tank warm for hours when no one is using it.
While most manufacturers provide a limited warranty, all of our tankless water heaters also come with a company-backed 3-year guarantee on workmanship. Our guarantee ensures that no matter what happens during the first 3 years, you’re covered at no cost. So, relax, and let us take care of you and your family’s comfort.


Advantages Include

• Eliminates energy & extra cost
• Never runs out of hot water
• Does not store and reheat water
• Provides cleaner hot water
• Lasts longer and is more durable than tanks
• Parts can easily be replaced
• Reduces the risk of basement floods
• Life expectancy can exceed 20 years

Water Heater Tanks

We also offer a full line of traditional tank water heaters ranging from 4 to 60 gallons. This is the perfect option for bigger households who have a high enough hot water usage to need accommodation that a tankless water heater might not be able to provide. With options of natural draft, power vent, and direct vent; Donaldson Heating & Air Conditioning can provide you with the right tank.
