Most Popular Types of Water Heaters

40 Gallon Water Heaters

Ideal for medium-sized households, 40 gallon water heaters strike a balance between adequate capacity and efficient use of space. These units typically serve families of 2-4 people and can handle several demands at once, such as running a shower and dishwasher simultaneously. They are available in both electric and gas models, offering flexibility depending on your home’s utilities. If your water usage is moderate and space is a premium, a 40 gallon unit might be perfect for you.

50 Gallon Water Heaters

For larger households with higher water demands, 50 gallon water heaters are an excellent choice. Suitable for families of 3-5 people, these water heaters can comfortably meet the higher hot water needs of multiple showers, laundry loads, and kitchen activities. They also come in electric and gas versions, providing consistent, reliable hot water. If your family frequently requires hot water from multiple sources at once, consider upgrading to a 50 gallon tank.

Tankless Water Heaters

Tankless water heaters, also known as on-demand water heaters, provide hot water only as it is needed, eliminating the need for a storage tank. These units are highly efficient, saving up to 30% more energy than traditional tank water heaters because they avoid the cost of maintaining the heat in a large volume of stored water. Although the initial installation cost is higher, the long-term savings on energy bills and the benefit of endless hot water make them a compelling choice for any household size.
