  • Homes finishing a basement and wanting to free up floor space
  • Owners replacing a rental tank who prefer to own their equipment
  • Households planning to stay in the home for many years

Local considerations

Scarborough water carries enough minerals that a tankless unit benefits from regular descaling, or a softener upstream. Gas tankless units need a gas line large enough to feed them at full output, which older homes sometimes lack. Venting runs through an exterior wall, so we look at clearances from windows, doors and the neighbour's lot line on narrow Scarborough lots.

Flow, not volume: Tankless units are rated by how many litres per minute they can heat. Sizing comes from how many fixtures run at once in winter, when incoming water is coldest.

How we install one

  1. We list your fixtures and peak use to size the unit.
  2. Gas line capacity and venting route are checked.
  3. Out goes the tank; the compact heater is hung on the wall.
  4. Service valves go on both lines so future descaling needs no pipe cutting.
  5. The unit is commissioned, tested at several fixtures and explained to you.

What affects cost

Gas line upgrades, new venting, condensate drainage and any electrical work for the unit's controls make the biggest difference.

Before you decide

Read tank vs tankless water heaters for a side-by-side look. We will tell you honestly if a tank would serve your house better.

Things callers ask us

Does a tankless heater need maintenance?

Yes. Periodic descaling keeps it efficient in hard water. The service valves we install make that straightforward.

Will I still get hot water during a power outage?

Most gas tankless units need electricity for controls and fans, so they stop during an outage.
