Expert Tankless Water Heater Services

Tankless models are wonderfully compact, about the size of a small suitcase, and can be mounted inside or out. There’s no standby energy losses, and because the water isn’t sitting in a tank, absorbing contaminants, your supply is clean and fresh. There’s also an endless amount, with no need to wait for the water to heat up. You also avoid the threat of flooding from a ruptured tank, and these modern systems tend to double the lifespan of conventional water heaters. While the investment is higher, the efficiency, ease of replacement parts, and longevity easily recover the cost. For all of your tankless water heating needs, including 24/7 Emergency Assistance, rely on Southwest Heating & Cooling for affordable service throughout Highlands Ranch, Littleton, Englewood, Lone Tree, Greenwood Village, Centennial, and Castle Pines, CO.

Routine Tankless Water Heater Maintenance

You can prevent the water heater from breaking in the first place by scheduling regular maintenance. Each year, a technician should flush out the water heater tank and remove any mineral buildup. It’s also important to inspect the anode rod, replace it if necessary, and inspect the safety features on the tank. This is important for tankless water heaters, as buildup on the heat exchanger can do a lot of damage!
