What we can help with
- Tankless installation: We size the unit to your household, including the gas line and venting the unit needs.
- Venting and condensate drain: Both installed to code.
- Annual descaling: A yearly service keeps scale off the heat exchanger and keeps the flow where it should be.
- Error codes and repairs: We diagnose the code, find what's behind it and repair it.
- Replacing a failed tankless unit: We swap the unit and correct anything in the original installation that caused the failure.
What to expect
We size the gas line and the vent to the unit and to your home, so the unit delivers the hot water it's rated for. A gas line that is undersized leaves you short of hot water and brings up error codes. Where we find one on an existing installation, we correct it as part of the work.
Hard water leaves scale inside a tankless heat exchanger, and scale costs you flow and efficiency. A yearly descaling clears it out and adds years to the unit. We go over what the service involves the first time we do it, and we'll let you know when the next one is due.

Frequently asked questions about tankless water heaters
Does a tankless heater ever run out of hot water?
No. A tankless heater makes hot water for as long as the tap is open, because there's no tank to empty. We size it to your house so two showers at once is not a problem.
Why does a tankless cost more to install?
The gas line, the venting and the unit itself all cost more than a tank installation. Every part of that is in your written price before you decide.
Does it need maintenance?
Yes, a descaling once a year. It's a short service, and it makes a real difference to how long the unit lasts.
