Tank Water Heaters

We've installed tank water heaters across the full spectrum — from standard residential units sized for crawlspaces or tight interior spaces, to 80–100 gallon commercial units for restaurants and large facilities. Brands we work with include Rinnai, Rheem, Navien, State, AO Smith, and more, in both gas and electric configurations.


Not sure what size or setup is right for your space? That's exactly the kind of question we're here to answer. Sometimes the best solution isn't obvious — a point-of-use instant unit, for example, can be a surprisingly practical fix for a break room or remote sink. We'll help you think it through before you commit to anything.

Tankless Water Heaters

Tankless water heaters deliver hot water on demand, take up less space, and are significantly more energy-efficient than traditional tank models — you're only heating water when you actually need it. For many households, that adds up to real savings over time.


The tradeoff is that choosing the right tankless unit requires matching the system to your home's size, usage patterns, and fuel source. Our team has installed a wide range of electric and gas tankless units and can walk you through the options without the overwhelm. As certified Rinnai installers, we're especially well-equipped to help if you're considering that brand — but we'll always recommend what genuinely fits your needs best.


Curious whether tankless is right for your home? Call or text us at 828-324-0500 and we'll talk it through.
