Electric Tankless for Guest Suites and Additions in Mount Pleasant, SC
Guest houses, guest suites and home additions often sit far from the main water heater. Running long hot water lines wastes water and energy. An electric tankless unit installed near the fixtures provides quick hot water. We size the unit for the space and its fixtures. This is an efficient solution for detached living spaces.

Hard Water Protection for Tankless Units in Mount Pleasant
Hard water can cause scale buildup in tankless heat exchangers and heating elements. Scale reduces efficiency and can trigger error codes. Most municipal water in South Carolina comes from rivers and reservoirs, so it tends to run soft and leaves less scale than in many other states. We recommend a water softener or scale inhibitor to protect your unit, and we install service valves for periodic descaling. Regular maintenance helps extend the life of your tankless heater.

Whole-Home Electric Tankless Installation in Mount Pleasant
Whole-home electric tankless units can supply multiple fixtures at once when properly sized. Models like the Stiebel Eltron Tempra and Rheem RTEX often require multiple dedicated 240 volt circuits.

High humidity speeds up corrosion on exposed copper and fittings in crawlspaces, so a quick look under the house is worth doing every year. We install isolation valves for simple descaling.
