Traditional & Tankless Hot Water Heater Solutions

The cost of a brand-new water heater unit can vary widely depending on the type & size (in gallons) of the water heater. This can 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 tankless 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 heated 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. Tankless water heaters also save space, so they’re much easier to install in a convenient location within your home.
Is Gas or Electric a Better Fuel Source for Dublin Homes: 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 Tankless Water Heater Does Your Home Need: Tankless-style water heaters units are measured in gallons per minute in reference to on-demand flow rate, and commonly range from 4- to 8-gallons per minute. Keep in mind, the larger the tank, the more costly it 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!

 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.
