Why Navien
- Endless hot water — a Navien tankless unit heats on demand, so you never run out.

- High efficiency, small footprint — condensing technology and a wall-mounted design save energy and floor space.
What We Install
We install and service Navien tankless water heaters and combi-boilers, sizing each unit to your home’s peak demand and confirming your gas and venting are right. Because much of Massachusetts has hard well water, we often pair a tankless install with a softener and set up periodic descaling to protect the unit. Our licensed crew also handles plumbing and HVAC.
FAQ
What is a combi-boiler?
A combi-boiler combines your home’s heating and hot-water heater in one wall-mounted unit — no separate tank — which saves space and improves efficiency. Navien’s NCB line is a popular choice.
Does hard water affect a tankless unit?
Yes — scale from hard water shortens any tankless heater’s life. We recommend a softener and periodic descaling so your Navien runs at peak for decades.
