Cost Factors
Type and Size
How much does it cost to replace a heater in a house? You need to think about the type and size of your heater before you start a replacement. The type affects the cost the most. Electric tank models usually cost less than gas or tankless water heaters. Tankless models save space and energy, but you pay more up front. The size matters too. Large families need bigger units, which increases the cost. If you pick a small heater, you might save money, but you risk running out of hot water. Always check the size chart for your home before you replace your heater.
