Gas Water Heater Replacement in Brampton

Sizing a tank for your household

Tank size is about more than the number of people. Look at your peak demand: two showers running in the morning while the dishwasher fills uses far more hot water than evenly spread use. Typical residential gas tanks range from about 40 to 75 US gallons. A key specification is the first-hour rating, printed on the label, which estimates how much hot water the tank can produce in an hour starting from a full tank. We match that rating to your household's busiest hour rather than simply copying the old tank's size. Households that have grown, or added a basement suite, often find the old tank was already running short.

Atmospheric versus power vent

An atmospheric heater sends exhaust up a metal vent into a chimney or shared flue, relying on natural draft. A power-vented heater uses a fan to push exhaust through plastic pipe, usually out the side wall. The choice depends on your home:

	Atmospheric	Power vent
Needs a chimney or flue	Yes	No
Needs electricity	Typically no	Yes, for the fan
Flexible placement	Limited	Greater
Common when	Sharing a flue with a mid-efficiency furnace	The furnace has become high efficiency

When a home upgrades to a high-efficiency furnace that vents through the wall, the water heater can be left alone in an oversize chimney, which can cause draft problems. Replacement is a good time to sort that out.

Rental tanks and ownership in Ontario

A lot of Ontario households rent their water heater through a monthly charge. If your current tank is a rental, the rental company owns it. Before replacing it with a purchased unit, check your agreement for return requirements and any buyout or removal fees, and arrange the return with the provider. We can install an owned tank once that is settled. The library comparison of renting versus buying lists the questions worth asking.

Removal and disposal

Swapping a heater means draining the old tank, disconnecting gas, water and venting, and carrying a heavy appliance out of the basement. We remove the old unit and dispose of it responsibly. The new heater is installed with a proper drain pan where needed, a temperature and pressure relief valve piped down to the floor, a gas shutoff and sediment trap, and a leak and draft check once it is running.
