If the storage-tank water heater in your Fresno area home is 10 years or older, it’s probably getting near the end of its useful service life. This is especially true if your conventional storage-tank heater has received minimal preventative maintenance, or if your water supply is full of minerals. While looking at suitable replacement units, or as a first-time installation in a new house, you may want to consider a tankless water heater. Although upfront cost for a tankless water heater is greater than for a conventional storage-tank type, the benefits, including reduced energy use, will last the lifetime of the unit. This should more than make up for the initial price difference.
