PROFESSIONAL TANKLESS WATER HEATER INSTALLATION IN CHILLIWACK
Installing a tankless water heater involves much more than mounting the unit on a wall. The system must be properly sized for your household’s hot water demand, while the gas supply, venting, condensate drainage, water piping and electrical requirements must all be evaluated for safe and reliable operation.
Armacom Plumbing & Heating provides professional residential tankless water heater installation throughout Chilliwack. With more than 35 years of plumbing and gas fitting experience, we carefully plan each installation around your home’s existing plumbing, gas system and hot water requirements.
Whether you’re replacing an existing tankless unit or converting from a conventional hot water tank, we’ll explain your options and recommend a system based on performance, efficiency and long-term value.

CHOOSING THE RIGHT TANKLESS WATER HEATER FOR YOUR HOME
Choosing the right tankless water heater involves more than selecting a brand or the highest BTU model. The system needs to be properly matched to your household’s hot water demand, number of bathrooms and fixtures, incoming water temperature, available gas supply and the location where the equipment will be installed.
Armacom Plumbing & Heating evaluates these factors before recommending equipment. Our goal is to install a tankless water heater that can comfortably meet your home’s hot water needs without unnecessarily oversizing the system.
We supply, install and service tankless water heaters from leading manufacturers including Navien, Rinnai, Rheem, IBC and Bradford White. Because we work with multiple manufacturers, we can recommend equipment based on your home’s requirements, installation conditions, features and budget rather than limiting you to a single brand.
WE CONSIDER:
✓ Household size
✓ Number of bathrooms
✓ Simultaneous hot water demand
✓ Existing gas line capacity
✓ Available installation space
✓ Venting requirements
✓ Recirculation options
✓ Water quality and maintenance requirements
✓ Budget and long-term operating costs
Not sure which tankless water heater is right for your home? We can compare the available options and explain the advantages of each system before you make a decision.
WHAT SIZE TANKLESS WATER HEATER DO I NEED?
Proper sizing is one of the most important parts of choosing a tankless water heater. Unlike a conventional hot water tank that stores a fixed volume of heated water, a tankless system heats water as it flows through the unit. The system therefore needs enough capacity to supply the fixtures your household may use at the same time.
Tankless water heaters are commonly rated by their flow rate in gallons per minute (GPM) and their heating capacity. The actual hot water a unit can deliver depends on several factors, including incoming water temperature, desired outlet temperature and how many fixtures are operating simultaneously.
A home with one or two occupants may have very different requirements than a larger Chilliwack household where two showers, a kitchen faucet and dishwasher could be operating at the same time. Simply choosing the largest unit isn’t always the best solution—the system should be properly matched to the home’s actual hot water demand.
WE CONSIDER YOUR HOME’S:
✓ Number of occupants
✓ Number of bathrooms
✓ Showers and tubs
✓ Kitchen and laundry hot water demand
✓ Simultaneous fixture use
✓ Incoming water temperature
✓ Required flow rate (GPM)
✓ Gas supply capacity
✓ Recirculation requirements
✓ Future household hot water needs
Armacom Plumbing & Heating professionally sizes residential tankless water heaters before installation. We evaluate your home’s hot water demand and existing plumbing and gas systems to recommend equipment capable of providing reliable hot water without unnecessary oversizing.
Every Tankless Water Heater Installation Chilliwack project begins with evaluating your home’s hot water demand, gas supply, venting requirements and installation conditions.
Why Proper Tankless Sizing Matters
An undersized tankless water heater may struggle when several fixtures require hot water at the same time. An unnecessarily oversized system can increase equipment and installation costs without providing a meaningful benefit. Proper sizing helps balance hot water performance, energy efficiency and long-term value.
CAN MY EXISTING GAS LINE SUPPORT A TANKLESS WATER HEATER?
One of the most important parts of a gas tankless water heater installation is confirming that your home’s natural gas system has enough capacity to safely supply the new equipment. Tankless water heaters can have significantly higher input ratings than conventional storage tank water heaters, particularly when operating at maximum demand.
This does not automatically mean your gas line needs to be replaced or upgraded. Before recommending any changes, Armacom Plumbing & Heating evaluates the existing gas piping, pipe sizing, developed length, available supply and the combined gas load of the appliances in your home.
If the existing gas system has adequate capacity, an unnecessary upgrade may be avoided. If additional capacity is required, we’ll explain what modifications are needed as part of the tankless installation.
As licensed gas fitters, we can complete the required gas piping modifications and ensure the new tankless water heater is installed in accordance with current British Columbia gas code requirements.
GAS SYSTEM ASSESSMENT INCLUDES
✓ Existing gas pipe sizing
✓ Total connected appliance load
✓ Tankless water heater BTU requirements
✓ Gas piping developed length
✓ Existing furnace and other gas appliances
✓ Required gas pressure and capacity
✓ Necessary piping modifications
✓ Final testing and commissioning

TANK OR TANKLESS? WHICH IS RIGHT FOR YOU?
Both traditional storage tank water heaters and modern tankless systems have their advantages. The right choice depends on your household size, hot water usage, available space, budget, and long-term plans. During your consultation, we’ll explain the pros and cons of each option so you can make an informed decision.
| Feature | Storage Tank | Tankless |
|---|---|---|
| Hot water supply | Limited by tank size | Continuous on demand |
| Energy efficiency | Good | Excellent |
| Equipment lifespan | 10–15 years | 20+ years with maintenance |
| Installation space | Floor mounted | Wall mounted |
| Standby heat loss | Yes | No |
| Upfront investment | Lower | Higher |
| Long-term operating cost | Higher | Lower |
PROFESSIONAL TANKLESS VENTING & CONDENSATE INSTALLATION
High-efficiency condensing tankless water heaters require properly designed venting and condensate drainage for safe, reliable operation. Venting requirements vary by manufacturer, model, installation location and the configuration of the home.
Armacom Plumbing & Heating installs approved venting systems according to the tankless water heater manufacturer’s specifications and applicable British Columbia code requirements. We also provide proper condensate drainage for high-efficiency condensing equipment.
During a tank-to-tankless conversion, the venting used by the existing storage water heater may not be suitable for the new tankless system. We evaluate the installation location and determine an appropriate venting route before the installation begins.
A PROFESSIONAL INSTALLATION MAY INCLUDE
✓ Intake and exhaust venting
✓ Manufacturer-approved vent materials
✓ Proper vent termination
✓ Combustion air requirements
✓ Condensate drainage
✓ Condensate neutralization where required
✓ Required clearances
✓ Final commissioning and safety checks
CONVERTING FROM A HOT WATER TANK TO TANKLESS
Replacing a conventional hot water tank with a tankless water heater can provide continuous hot water, improve energy efficiency and free up valuable space in your home. However, a tank-to-tankless conversion involves more than simply removing the old tank and mounting a new unit on the wall.
Armacom Plumbing & Heating evaluates your home’s hot water demand, gas supply, venting options, water piping, condensate drainage and installation location before recommending a tankless system. This allows us to determine what modifications are required and provide a properly planned residential installation.
For many Chilliwack homeowners, the best time to consider tankless is when an aging conventional water heater is already approaching replacement. We can compare both options so you can decide whether another storage tank or a tankless system provides better long-term value for your home.
A TANK-TO-TANKLESS CONVERSION MAY INCLUDE
✓ Removal of the existing hot water tank
✓ Proper sizing of the new tankless system
✓ Gas supply assessment and modifications where required
✓ New hot and cold water connections
✓ Approved intake and exhaust venting
✓ Condensate drainage for condensing equipment
✓ Electrical connection requirements
✓ Recirculation options where appropriate
✓ System setup, testing and commissioning
✓ Disposal of the old water heater
SHOULD I REPLACE MY TANK OR UPGRADE TO TANKLESS?
Tankless isn’t automatically the best choice for every home. Installation cost, available gas capacity, household hot water demand, existing venting and how long you plan to remain in the home can all affect the decision.
Armacom can compare a conventional replacement with a tankless upgrade and explain the installation requirements, advantages and costs of each option before you decide.
WANT HOT WATER FASTER? ASK ABOUT RECIRCULATION
A tankless water heater provides continuous hot water, but it does not necessarily mean hot water will reach every faucet instantly. Water sitting in the piping between the heater and fixture still needs to be displaced before hot water arrives.
Depending on the home and tankless system selected, a hot water recirculation system may help reduce the wait for hot water at distant fixtures. Some tankless models offer built-in or compatible recirculation features that can be incorporated into the installation.
During the initial assessment, Armacom can discuss whether recirculation makes sense for your home’s plumbing layout and hot water usage.
TANKLESS WATER HEATER MAINTENANCE & DESCALING
Tankless water heaters require regular maintenance to help maintain performance, efficiency and reliable operation. Over time, minerals can accumulate inside the heat exchanger and water passages, particularly in areas with mineral-rich water.
Armacom Plumbing & Heating provides professional tankless water heater maintenance and descaling for Chilliwack homeowners. Regular service can help remove mineral buildup, identify developing problems and keep the system operating as intended.
Maintenance requirements vary by manufacturer, model, water quality and household usage. We recommend following the manufacturer’s maintenance requirements and adjusting the service schedule when operating conditions require more frequent attention.
WHAT DOES TANKLESS MAINTENANCE INCLUDE?
✓ Inspect the tankless water heater and connections
✓ Flush and descale the heat exchanger
✓ Clean accessible water inlet filters
✓ Inspect condensate drainage
✓ Check venting and terminations
✓ Inspect for leaks or signs of deterioration
✓ Review error codes or operating concerns
✓ Test system operation after servicing
✓ Identify developing repair or maintenance issues
WHY DESCALING MATTERS
Mineral scale can restrict water flow and reduce heat-transfer performance inside a tankless water heater. Left unaddressed, buildup may contribute to reduced performance and unnecessary stress on components.
Periodic flushing and descaling helps remove these deposits and is an important part of protecting your investment.
WHY DESCALING MATTERS
There isn’t one maintenance interval that’s right for every tankless water heater. Many manufacturers recommend regular or annual maintenance, but the appropriate schedule depends on the model, water quality and how heavily the system is used.
Chilliwack homeowners should also consider local water conditions when planning maintenance. Armacom can inspect the system and recommend an appropriate service interval based on the equipment and its operating conditions.

TANKLESS WATER HEATER REPAIR OR REPLACEMENT?
A problem with a tankless water heater doesn’t automatically mean the system needs to be replaced. Many issues can be diagnosed and repaired, particularly when the equipment is otherwise in good condition and replacement parts remain available.
Armacom Plumbing & Heating can assess the system, review error codes and operating symptoms, and help determine whether repair, maintenance or replacement is the most practical option for your home.
When a tankless water heater is older, experiencing repeated failures or requires a significant repair, replacement with a newer high-efficiency system may provide better long-term value.
SIGNS YOUR TANKLESS WATER HEATER MAY NEED SERVICE
✓ No hot water
✓ Water temperature fluctuates
✓ Reduced hot water flow
✓ Tankless unit repeatedly shuts down
✓ Error codes appear on the controller
✓ Unusual noises during operation
✓ Water leaking from or around the unit
✓ Ignition or burner problems
✓ System hasn’t received regular maintenance
✓ Performance has noticeably declined

TANKLESS WATER HEATER FAQS
Have questions about tankless water heater installation, sizing, maintenance or upgrading from a conventional hot water tank? Here are answers to some of the most common questions we receive from Chilliwack homeowners.
A tankless water heater can be a good choice for homeowners who value continuous hot water, energy efficiency, compact equipment and long-term performance. Whether it’s the best choice depends on your household’s hot water demand, existing gas system, installation requirements and budget. Armacom can compare tankless and conventional options for your home.
Yes, many conventional hot water tanks can be replaced with tankless systems. A conversion may require changes to the gas supply, water piping, venting, condensate drainage and electrical connection. We evaluate these requirements before recommending equipment.
Tankless water heaters should be sized according to household hot water demand, simultaneous fixture use, incoming water temperature and required flow rate. Armacom evaluates these factors before recommending a system rather than simply installing the largest available unit.
Not necessarily. Some homes already have sufficient gas capacity, while others require piping modifications. We assess the existing gas piping and connected appliance load to determine whether an upgrade is required.
Yes. Armacom Plumbing & Heating is licensed and insured to provide professional plumbing and gas fitting services. Tankless water heater installations are completed in accordance with applicable British Columbia plumbing and gas code requirements and manufacturer installation specifications.
Maintenance frequency depends on the manufacturer, model, water quality and household usage. Regular inspection, flushing and descaling can help control mineral buildup and maintain system performance. Armacom can recommend an appropriate maintenance schedule for your equipment.
Service life varies considerably depending on equipment quality, installation, water conditions, usage and maintenance. Regular professional maintenance and addressing problems early can help protect the system and maximize its useful life.
Tankless means the system heats water on demand, but hot water still needs to travel through the piping to the fixture. Depending on the home’s plumbing layout, a recirculation system may help reduce the wait for hot water at distant fixtures.
Rebate and energy-efficiency programs change periodically and may have specific equipment, homeowner and installation requirements. We recommend checking current program eligibility before purchasing equipment rather than assuming every high-efficiency tankless water heater qualifies.
