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. Christopher was fantastic! Arrived right on time, friendly, happy in his work. Very informative and taught me a lot about water heaters! Luckily for me, my problem was the pilot light. However, he also checked for gas, leaks and various other possible problems. He informed me of future maintenance and suggested repairs for the future.

 Trustindex verifies that the original source of the review is Google. Elston Walker was the water heater technician that Castle Works dispatched after regular hours when our 25 year old water heater went out with a splash😩Elston has a brand new up to date technology water heater installed within 2 hours. We caught our flight and now I am posting this from Lisbon Portugal and our daughter has all the hot water she needs!🤣
