Tankless water heater installation and repair

Endless hot water when it is installed right, and a lot of frustration when it is not. Our certified techs install new tankless systems and repair the ones blowing cold or flashing error codes.

Financing available

Big repairs rarely come at a good time. Ask about monthly payment options.

Tankless done right at 5,280 feet

Gas tankless water heaters need the right gas supply, venting, and settings to perform, and Denver's altitude affects how gas appliances burn. Undersized gas lines and poor setup are behind many tankless complaints.

Regular flushing matters too. Mineral buildup in the heat exchanger reduces output and triggers error codes.

Signs your tankless needs service

Switching from a tank, or replacing an older tankless unit, starts with sizing it to your household.

Tank to tankless conversions

We remove the old tank and set up the new system, including gas and venting changes.

Sized to your home

Sized for your fixtures and how many run at once, so it keeps up.

Questions we hear a lot

For many households, yes: endless hot water, a smaller footprint, and lower standby energy loss. The upfront cost is higher than a tank, so we walk through whether it fits your home and usage.

Often. Gas tankless units draw a lot of gas at full output, and many existing lines were sized for a tank. We check during the estimate and include any upgrade in the price.

Common causes include low flow through the unit, scale buildup, venting or gas supply problems, and failing sensors. We diagnose the actual cause.

Our certified technicians repair all major tankless brands.

Many models can, with the right venting and freeze protection. We will tell you whether an outdoor install makes sense for your home.
