Tankless Water Heater Installation

Tankless water heaters require higher BTU input than tank heaters. We'll assess your gas line and upgrade it if necessary to ensure proper operation.

Most homeowners see 20-40% reduction in water heating costs. Tankless units only heat water when you need it, eliminating standby heat loss.

Most tankless water heater installations are completed in one day. If gas line upgrades are needed, it may take an additional day.

Yes, when properly sized. The key is choosing a unit with enough flow rate measured in gallons per minute. We calculate your household peak demand by adding up all fixtures that might run simultaneously, then recommend a unit that can handle that load. Larger homes sometimes benefit from two units.

This happens when you get a brief burst of cold water between uses because cool water sitting in the pipes reaches the faucet before newly heated water arrives. Quality units like Navien have built-in recirculation features that minimize this. We can also install a small buffer tank or recirculating system to eliminate the issue entirely.

Yes, annual maintenance keeps your tankless running efficiently. The main task is flushing the heat exchanger with a descaling solution to remove mineral buildup, especially in areas with hard water. We offer maintenance service that includes flushing, filter cleaning, and system inspection to extend the life of your unit.

Most tankless units use direct vent systems that draw combustion air from outside and exhaust through a dedicated pipe. This allows flexible placement since you do not need a traditional chimney. Concentric venting uses one pipe inside another, while two-pipe systems use separate intake and exhaust lines. We choose the best option based on your installation location.

For many homeowners, yes. While tankless units cost more initially, they last nearly twice as long as tank heaters and reduce monthly energy bills by 20-40%. The payback period depends on your hot water usage and local energy costs. We can help you run the numbers for your specific situation.

Some models are rated for outdoor installation, which saves indoor space and simplifies venting. Outdoor units have freeze protection built in, though extremely cold Connecticut winters mean we usually recommend indoor installation unless you have a compelling reason to go outside. We can discuss the pros and cons for your situation.
