Tankless Water Heater Installation for Mississauga Homes

A tankless heater fires only when a hot tap opens. It frees floor space and never runs out partway through a shower, provided the gas line and vent are up to the job.

Is tankless right for your house?

  • You want to free up space in a small mechanical room.
  • Long showers back to back leave the family short of hot water.
  • You expect to stay put until the fuel savings cover the cost.
  • Your gas meter and line can deliver the higher flow these units need.

What makes Mississauga installs different

Incoming water from the lake is cold in winter, sometimes just a few degrees above freezing. A tankless unit must raise that temperature a long way, so sizing for a January morning matters more than sizing for July. Older homes often still feed the first tank with a half-inch gas pipe, which may be too small for a condensing tankless model.

How we install it

  1. We measure the gas line size and length and confirm the meter capacity.
  2. We plan the vent route: condensing models usually exhaust sideways through the wall in plastic pipe.
  3. The old tank is removed and the wall-mounted unit is hung and plumbed.
  4. Service valves go on so the heat exchanger can be flushed in future.
  5. Gas, water, condensate drain and venting are tested before handover.
N.B. Hard water means a tankless heater wants flushing on a schedule. Our page on tankless descaling covers what that involves.

What moves the bill

Upgrading the gas line is often the largest extra. Vent length, a condensate drain route and electrical supply for the unit also count. A permit is typically needed for gas appliance work.

Worth asking

Ask what flow rate the unit delivers at your winter inlet temperature, not just its maximum. Ask whether a water softener or scale filter is recommended, and how often the unit should be flushed.

What callers want to know

Do tankless heaters work during a power cut?

Most need electricity for their controls and fan, so they stop during an outage, as do power-vented tanks.

Will I wait longer for hot water at the tap?

Slightly, in some cases, since the unit starts heating only once flow begins.
