O2 HVAC installs, replaces and repairs gas and electric water heaters across Abbotsford, from standard hot water tanks to high-efficiency tankless systems. Gas connections are made by licensed gas fitters, under permit, with no hidden extras.

Whether you’re adding a basement suite, building a new home or tired of running out of hot water halfway through a shower, the right water heater depends on how many people use it, how much space you have and what fuel your home runs on.
Our water heater installation in Abbotsford starts with a quick look at your current setup: the gas line, venting, water pressure and where the heater sits. Then we recommend the right size and type, quote it in writing, and install it to code in a single visit for most homes.

| Hot water tank | Tankless (on-demand) | |
|---|---|---|
| How it works | Keeps 40 to 75 gallons hot at all times | Heats water only when a tap is opened |
| Hot water supply | Can run out with back-to-back showers | Continuous, as long as it’s sized right |
| Space | Floor space in the mechanical room | Mounts on the wall, frees up floor space |
| Lifespan | About 8 to 12 years | About 15 to 20 years with yearly maintenance |
| Upfront cost | Lower | Higher, especially if the gas line needs upgrading |
| Best for | Smaller households, tight budgets | Families, homes with suites, new builds |
For many Abbotsford homes with a basement suite, a properly sized tankless water heater, or a larger tank, avoids the “who showers first” problem between two households.
A tankless water heater installation in Abbotsford is more than hanging a unit on the wall. Most gas tankless models need:
We size the unit by your peak demand, how many showers and taps run at once, not just the number of bathrooms.
A new hot water tank is still the simplest, lowest-cost option for many homes. We install gas water heaters and electric tanks from 40 to 75 gallons, including power-vent models for homes without a chimney. Every hot water tank installation includes:
Many homeowners search for a plumber for water heater installation in Abbotsford. For a gas water heater in BC, the gas connection must be made by a licensed gas fitter working for a licensed gas contractor, under a Technical Safety BC gas permit. O2 is a licensed gas contractor [licence #], so one team handles the water, gas and venting, pulls the permit and books the inspection.
We check your gas line, venting, water pressure and the space available.
Model, size, venting, permit and any extra parts, with removal of the old heater included.
We shut off gas and water, remove the old heater, install and connect the new one, and strap it to code.
We test for gas leaks, check the venting and relief valve, set the temperature and show you the shut-off valves.
Most tanks last 8 to 12 years. Signs it’s time for a hot water tank replacement in Abbotsford:
A leaking tank can flood a basement quickly. If yours is leaking, shut off the cold water valve on top of the tank and the gas or power, then call 604-619-0202. We offer emergency and same-day water heater replacement, and carry common tank sizes on the truck. [O2 to confirm same-day availability]
When you replace, it’s also a good time to consider going tankless, or replacing your furnace and water heater together in our Full Mechanical Room Upgrade.
Not every problem means a new tank. Our water heater repair service in Abbotsford fixes:
pilot, thermocouple, gas valve or igniter faults on gas tanks; elements or thermostats on electric tanks
a broken dip tube, sediment build-up or a failing element
scale build-up, flame failure or venting faults
relief valves, drain valves and connections
blower motors and pressure switches
If the tank itself is leaking, or the heater is over 10 years old and needs a major part, replacement usually makes more sense. We’ll quote both so you can compare.
Here are typical installed prices, including removal of the old heater:
What changes the cost: tank size or tankless capacity, gas line upgrades, new venting, an expansion tank, moving the heater to a new spot, and after-hours service.

Many Abbotsford water heaters we replace are well past their 10-year mark. We install, replace and repair water heaters in every Abbotsford neighbourhood, including Clearbrook, Historic Downtown, Mill Lake, Auguston, Eagle Mountain, Sandy Hill, Townline Hill, Aberdeen, Mount Lehman, Bradner, Matsqui and Sumas Prairie. We also serve Chilliwack and Mission.
A tank-for-tank replacement usually takes two to four hours. Switching from a tank to tankless takes most of a day because of the gas line and venting work.
Gas tanks need a Technical Safety BC gas permit and a licensed gas fitter. All tanks need seismic strapping, a temperature and pressure relief valve with a drain line, and proper venting, plus an expansion tank where the water system needs one.
It is for larger households, homes with suites and anyone planning to stay put. It costs more up front but lasts longer, saves floor space and doesn’t run out of hot water. For a small household on a budget, a high-quality tank is often the better value.
For a tank, most families of three to four need 50 gallons; larger households or homes with a suite need 60 to 75. For tankless, it depends on how many fixtures run at once. We size it at the quote.
A leak from a valve or fitting can often be repaired. A leak from the tank itself means the inner lining has rusted through, and the tank needs replacing.
Yes. Heat pump water heaters use a fraction of the electricity of a standard electric tank and may qualify for rebates. Ask us at your quote.
