Tankless Water Heater Installation in Newmarket
A tankless unit heats water as it passes through, so it never runs a tank empty. It also asks more of your gas line and venting than an old tank did.
- Same-visit diagnosis on gas and electric tanks
- Draft and gas-leak tests on every heater we touch
- Old tank drained, hauled and disposed of
- Owned or rented tanks both serviced
Cues for tankless water heater installation
- Your rented or owned tank is past twelve years and you want to stop paying for storage.
- The family runs out of hot water during back-to-back showers.
- You are finishing the basement and want the floor space a tank uses.
- A large soaker tub drains a standard 40- or 50-gallon tank before it is full.

What fails inside the pipe, and why
Many homes here still have a rented tank in the furnace room, and owners look at the monthly charge and wonder about switching. The catch is supply: a tankless burner can draw far more gas at peak than the old tank, and a half-inch line run decades ago may not carry it. Hard water matters too. Scale coats the heat exchanger, so a unit here needs service valves that let it be flushed with descaling solution on a schedule.
On the job: tools, parts and steps
- Size it. We count fixtures you run together and use winter inlet temperature, which is cold in York Region, to pick the right flow rating.
- Check the gas. The meter, pipe size and run length are measured against the unit's demand. Undersized lines get upsized before install.
- Vent it. Most condensing units exhaust sideways out the wall through PVC or polypropylene, kept clear of windows, the gas meter and snow line.
- Plumb for service. Isolation valves with flush ports, a pressure relief valve and a condensate drain to a floor drain or pump.
- Fire and test. Gas tightness test, combustion check and a long hot run at the farthest tap.
What decides how big the job gets
- Unit size and whether it is a combination unit also feeding heating.
- Gas line upgrades and vent route length.
- Removing and returning a rental tank.
- Permit and inspection requirements for gas work.
Shut it off and call, or book it?
Tankless is a planned job, not a midnight one. If your tank has failed outright, we can restore hot water first with a tank swap and plan tankless later. Homes in Woodland Hill often have the wall space and gas capacity to make the switch straightforward.
Asked on site
Does tankless mean endless hot water?
As long as demand stays within the unit's flow rating. Run three showers on a unit sized for two and the temperature drops.
How often does it need descaling?
With Newmarket's hard water, plan on an annual flush to begin with. A softener upstream stretches that out.
Will it work in a power outage?
No. Tankless units need electricity for controls and the fan, so hot water stops when the power does.
