HOW MUCH DOES A TANKLESS WATER HEATER COST IN CHILLIWACK?
Tankless water heater costs in Chilliwack vary depending on whether you’re replacing an existing tankless system or converting from a conventional hot water tank. Equipment selection, gas piping, venting, condensate drainage and the existing installation can all significantly affect the final price.
For budgeting purposes, the following ranges provide a starting point for professionally installed residential gas tankless water heaters.
EXISTING TANKLESS REPLACEMENT
$3,500 – $5,500+ Replacing an existing tankless water heater where much of the existing infrastructure is suitable for the new equipment.
TANK-TO-TANKLESS CONVERSION
$4,500 – $7,000+ Converting a conventional hot water tank to tankless, including typical piping, venting and installation modifications.
COMPLEX TANKLESS CONVERSION
$6,000 – $10,000+ Projects requiring more extensive gas piping, difficult venting, relocation or other significant installation modifications.
These are general 2026 planning ranges, not quotations. Your actual price will depend on the tankless water heater selected and the installation requirements of your home. Equipment and material costs may also change due to manufacturer pricing, availability, exchange rates, tariffs and supply-chain conditions.
When comparing Tankless Water Heater Cost Chilliwack homeowners should consider more than the price of the unit itself. Gas supply, venting, plumbing modifications, installation complexity and equipment availability can all affect the final installed price.

WHAT AFFECTS TANKLESS WATER HEATER COST?
Two Chilliwack homes can require very different tankless installations. The final cost depends on the equipment selected, the home’s hot water requirements and how much of the existing plumbing, gas and venting infrastructure can be used.
TANKLESS EQUIPMENT
Different manufacturers, capacities, efficiency levels and recirculation features affect equipment cost.
VENTING
Existing venting may be reusable in some tankless replacements, while conversions or different equipment may require new intake and exhaust venting.
SYSTEM SIZING
Household size, number of bathrooms and simultaneous hot water demand help determine the capacity required.
PLUMBING & CONDENSATE
Water piping, service valves and condensate drainage requirements can add to the installation scope.
GAS PIPING
The existing gas system must have sufficient capacity for the selected tankless water heater. Some installations require gas piping modifications while others may not.
INSTALLATION COMPLEXITY
Equipment relocation, difficult access, longer piping runs or extensive modifications can increase labour and material costs.
Tankless water heater cost in Chilliwack can vary considerably depending on the equipment selected, installation requirements, gas and venting upgrades, and whether you’re replacing an existing tankless unit or converting from a traditional hot water tank.
The lowest equipment price doesn’t necessarily mean the lowest installed price. Selecting equipment that works well with the home’s existing mechanical systems can sometimes reduce the modifications required and provide better overall value.
REPLACEMENT VS. CONVERSION: WHY DOES CONVERSION COST MORE?
Replacing an existing tankless water heater can often cost less than converting a conventional hot water tank because some of the infrastructure required for tankless equipment may already be installed. A conversion starts with a home that wasn’t necessarily designed around a tankless system, so additional work may be required.
EXISTING TANKLESS REPLACEMENT
Typically $3,500–$5,500+
Often involves:
✓ Removing the existing tankless unit
✓ Installing properly sized replacement equipment
✓ Adapting existing water connections
✓ Evaluating existing gas piping
✓ Evaluating existing venting
✓ Connecting condensate drainage
✓ Setup, testing and commissioning
When compatible infrastructure can be reused, replacement can be relatively straightforward.

TANK-TO-TANKLESS CONVERSION
Typically $4,500–$7,000+
May involve:
✓ Removing the conventional hot water tank
✓ Installing the new tankless system
✓ Gas piping modifications
✓ New intake and exhaust venting
✓ Water piping modifications
✓ New condensate drainage
✓ Electrical requirements
✓ Testing and commissioning
More complex conversions involving significant gas, venting, relocation or other modifications may reach $6,000–$10,000+.

We’ll assess what’s already there before recommending modifications. Existing piping or venting shouldn’t be replaced simply because it’s old if it’s compatible, properly sized and suitable for the new equipment.
Tankless Water Heater Cost Chilliwack estimates can also vary depending on whether you are replacing an existing tankless system or converting from a traditional hot water tank.
IS A TANKLESS WATER HEATER WORTH THE COST?
Tankless water heaters typically cost more to install than conventional hot water tanks, particularly when a home requires gas piping, venting or other modifications. Whether the additional investment makes sense depends on your household’s hot water demand, existing installation, available space and how long you expect to remain in the home.
For some homeowners, the benefits of continuous hot water, high-efficiency operation and eliminating a large storage tank justify the higher initial cost. For others, another conventional hot water tank may provide better overall value.
TANKLESS MAY BE WORTH CONSIDERING IF:
✓ Your household has significant hot water demand
✓ You frequently run out of stored hot water
✓ You want to reclaim floor space
✓ You’re planning to remain in the home long term
✓ High-efficiency equipment is important to you
✓ Your existing mechanical systems make conversion practical
A CONVENTIONAL TANK MAY OFFER BETTER VALUE IF:
✓ Lowest upfront cost is the priority
✓ Your household has modest hot water needs
✓ Major gas or venting upgrades would be required
✓ Your existing tank installation is straightforward
✓ The additional tankless features aren’t important to you
Armacom can quote both options. If another conventional hot water tank makes more financial sense for your home, we’ll explain that option rather than pushing you toward the more expensive system.
We’ll recommend equipment based on your home—not simply the largest available unit. Proper sizing helps ensure the tankless system can meet your household’s hot water demand without unnecessarily oversizing the equipment.
