Water Heaters Only, Inc has been serving the community of Mission Viejo for over 57 years since 1968. Specializing in the repair and replacement of traditional water heaters, tankless water heaters and heat pump water heaters, we have made hot water our business.
In Mission Viejo, we primarily install 40 and 50 gallon gas water heaters. Tanks of this size are perfect for 1-4 bedroom homes and are fairly standard for the area. We recommend replacing your current water heater with one of the same size, getting you back in hot water within a few short hours and saving you money with a fast, easy replacement. If you are wanting more hot water, we can increase the size of your water heater to 75 or even 100 gallons, or replace your traditional water heater with a tankless heater. These tankless (on-demand) water heaters do not rely on gallon capacity but rather a gallon-per-minute flow rate unique to each home. These smaller, more compact water heaters offer you endless hot water whenever you want it.
