Traditional & Tankless Hot Water Heater Solutions

Before Dublin winter is here, you’ll want to ensure your water heater is working at 100% efficiency and supplying all the hot water you need. That’s why it is important to have your water heater serviced with an annual tune-up. A hot water heater maintenance tune-up has 3 primary benefits:

Increased Water Heater Efficiency & Money Saved: One of the most common issues to occur in your water heater is buildup of sediment from loose minerals in your Dublin water supply. The more buildup, the less efficient your water heating unit becomes. Banging or knocking is usually an indication of buildup on the bottom of your water heater, and that means it’s time to call the experts at CastleWorks Water Heaters of Dublin to get your annual water heater maintenance.
Minimize the Risk of Water Heater Breakdown: By having your water heater maintained yearly in Dublin, you decrease the risk of a costly water heater repair or replacement. Our experts will tune-up your water heater and check for any signs of corrosion, water leakage, or anything else that may be keeping your water heater from functioning at 100% efficiency.
Ensure Hot Water All Year Long: There’s nothing worse than waking up to cold water running through your shower. Ensure this doesn’t happen to your Dublin water heater by getting your annual maintenance tune-up scheduled today with the expert plumbers at CastleWorks Water Heaters of Dublin.

No matter the season, our water heater maintenance & tune-up plumbers will ensure your water heater is 100% functional & ready to accommodate your hot water needs. You can expect our experts to notify you of any repair needs before any work is done, so you will know exactly what solution is best for your home’s water heater unit.

 Trustindex verifies that the original source of the review is Google. After 1 appointment cancellation at request of firm, Justin arrived on the next scheduled visit.   His service was thorough and well explained. He also decided to not bill extra on an existing condition and he chose not to pursue.   Overall very happy with the service and confident in the work performed.

 Trustindex verifies that the original source of the review is Google. Luis came out and was very professional.  The appointment was scheduled in a very timely manner and the problem was taken care of in the same day with a new installation of a new water heater due to the old one wearing out and leaking.
