Fast, efficient, and professional. I went to turn my heat on and realized my boiler wasn’t working. It was a Friday before a long holiday weekend but James had one of his guys there first thing Monday morning and my heat was back up and running in just a few hours! Thank you so much!! Highly recommend

Met with me on short notice and took the time to talk about all options, but brief and to the point.
Helped me make a better decision.
Went above and beyond so the work got done in a timely manor and we're very satisfied with the results.
Thank you, James & Crew.

Excellent service. Responded quickly to confirm my appointment and the work was completed quickly the same day. We will be using this company for our yearly heating maintenance.

I had a great experience working with James and his team to install our new boiler and water heater. He worked to understand our needs, gave us solid advice, and provided a competitive bid with no extras or upsells (and no BS!).  His work was very professionally done, and it was obvious that he took great pride in his work and in providing the most useful components. He also took the time to explain the work, how the equipment worked, and made sure the settings were what we we were looking for.  All in all a great experience, and we will be working with him again.

Frequently Asked Questions

How do I know what size water heater I need?

Sizing depends on the number of people in your home and your typical hot water usage. Dalelis plumbers will assess your needs and recommend the right capacity.

Should I choose a tank or tankless water heater?

Tank water heaters are more affordable upfront and work well for most homes, while tankless systems provide on-demand hot water and improved energy efficiency. The right option depends on your usage, budget, and space. We’ll walk you through both options before installation.

How long does water heater installation take?

Most water heater installations are completed within two to four hours. Tankless installations or jobs requiring code upgrades may take longer, and we’ll always explain the timeline in advance.

Can I replace my old water heater with a different type?

Yes. Many homeowners upgrade from tank to tankless or switch fuel types. We’ll evaluate venting, electrical, and gas requirements to ensure the new system is installed safely and meets local codes.

What factors affect the cost of water heater installation?

Installation cost depends on the type of system, capacity, fuel source, venting requirements, accessibility, and whether any plumbing or code updates are needed. Dalelis provides transparent pricing before work begins.
