Bathrooms, fixtures, and simultaneous use determine the unit size and whether tankless fits the home.
Tankless units often need gas-line and venting review before installation is approved.
Hard water can affect tankless performance and maintenance needs.
Flush valves, clearances, and drain routing matter for future maintenance.

Real answers to questions Mississauga and GTA customers ask us most.
Tankless units cost more upfront but last longer (often 20+ years), use less energy when sized right, and free up floor space. They suit households with steady or modest hot water demand.
Most homes can. We confirm gas line capacity, venting routes, and electrical needs before quoting.
Most tankless installs take a full day, sometimes longer if gas line or venting needs upgrading.
We size around flow demand, gas capacity, venting, available wall space, and budget so the quoted unit fits the home.
