A storage tank keeps 40–60 gallons hot around the clock; a tankless unit heats water only as you use it. Tankless wins on running cost, lifespan, and endless hot water; a quality tank wins on upfront price and simpler installation. The right answer usually comes down to your household's hot-water habits and your home's gas and venting setup.
When is tankless worth the premium?
- Your household regularly runs out of hot water — tankless never does
- You plan to stay 8+ years, long enough for efficiency savings to repay the install
- Space matters — a wall-hung tankless frees the floor area a tank occupies
- Your tank is past 10 years old anyway, so you're already facing replacement
When does a tank still make sense?
If the budget is tight, the existing venting suits a tank, or the home is a rental where running cost lands on someone else, a good storage tank is a perfectly rational choice. We install both and will tell you plainly which the numbers favour in your case.
What's the maintenance difference?
Tanks silently accumulate sediment — an annual flush extends their life and keeps recovery fast. Tankless units need periodic descaling, especially in harder-water pockets of the valley; skip it for years and the heat exchanger pays the price. Neither is onerous, but neither is optional if you want rated lifespan.
Big Valley installs and services both types across the Fraser Valley, including the venting and gas-line work in-house — no subcontracted corners on the part of the job that keeps your family safe.
