Traditional & Tankless Hot Water Heater Solutions

The cost of a brand-new water heater can vary widely depending on the type & size (in gallons) of the water heater. Prices can also vary considerably between the two types of water heaters: traditional tank & tankless. In addition, there are several other factors that can affect the overall cost of a water heater installation or replacement:

What’s the Difference Between a traditional tank Water Heater & a Tankless Water Heater in Dublin: A traditional tank water heater stores gallons of water, so hot water is always available. A tankless water heater will heat up water on-demand, which will save you money in energy costs down the road. Traditional storage tank water heaters are much easier & cheaper to install.
Is Gas or Electric a Better Fuel Source: This decision can be heavily dependent on your geographic location & local natural gas and electricity costs. However, it’s generally a bit more expensive for a gas water heater than an electric water heater.
What Size Water Heater Does Your Dublin Home Need: Traditional tank-style water heaters can range from 20- to 80-gallon tanks, with 40-gallon being the most common. Keep in mind, the larger the tank, the more costly will be for the unit itself & the heating costs. Let the plumbing experts at CastleWorks Water Heaters of Dublin help you decide which option is best for your home with an installation evaluation & cost estimate today!

No matter what your hot water needs are, our expert plumbers will determine the best water heater type & size for your home with professional advice on your installation before any work is done.

 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!🤣

His service was thorough and well explained. He also decided to not bill extra on an existing condition and he chose not to pursue.
