Attempting to install a hot water system yourself risks serious safety issues from gas leaks, electric shocks and water damage. Hire a licensed professional for safe, compliant installation meeting all requirements.
Installing the right hot water system is essential for home comfort and daily convenience.
The two main types to consider are storage tank systems that heat and store hot water, or continuous flow systems that heat water on demand. Although DIY water heater installation may seem cost-effective, the complexities of gas-electric systems require precise plumbing and often necessitate professional training and licensing.
When your professional plumber installs your water heater, make sure safety is the number one priority. Utilising a licensed plumber, who can assure adequate power to install your system, can not only ensure safety but also save money in the long run. experts can ensure your water systems can meet compliance with codes and confirm safe operation.
Hot water heaters operate under high temperatures and pressures, posing risks of leaks or electrical issues if not properly managed.
This article will provide insights on your hot water replacement during the installation process. We’ll look at safety procedures, sizing, permits, part replacements like relief valves and thermostats for hot water heaters, pressure testing, final inspections and more. While some DIY enthusiasts may attempt to install water heaters, such tasks require caution and are typically best left to professionals.
Different types of hot water systems, such as gas models, are available, each with unique components, lifespans, and installation costs:
Gas Storage Tank - Rely on a gas burner or heating elements and a drain valve to heat storage hot water in an insulated tank. Common components include the gas valve and burner, the TP valve, anode rod and thermostat. Lifespan is 6-12 years.
Electric Storage Tank - Use electric hot water heating elements to warm a tank of water. Include elements, thermostat and anode rod. Last 8-15 years.
Gas Tankless - Heat water directly without a storage tank as needed. Consist of a gas burner, heat exchanger and computerised control board, unlike electric water systems that use electric elements. Lifespan of up to 20 years.
Electric Tankless - The electric water heater uses electric elements to instantly heat water on demand. Made up of heating elements, temperature sensors and electronic control boards. Can last over 20 years.
Heat pump water heaters absorb ambient heat from the environment or natural gas, transferring it to the water in an insulated tank as needed. Key parts are the evaporator/condenser heat pump coil, compressor and backup electric elements. Last for 10-15 years.
When you install hot water heater setups, your system can align with manufacturer specifications, gas and plumbing codes. Professional advice is crucial to ensure your hot water system is sized appropriately for safe and efficient performance.
If you choose to install a water heater yourself, prioritise safety at all times. ensure you wear protective gear and turn off the cold water supply to safely handle your old water heater, avoiding leaks or electrocution. Have an ABC fire extinguisher on hand.
Carefully review the instruction manual before installing new water heater components and ensure I have all necessary materials and tools beforehand. An incorrect installation of even some hot water components is a significant concern, as it can result in serious hazards like carbon monoxide leaks.
Considerations for new hot water system installations should include components such as a drain pan, pressure relief valve, expansion tank and earthquake straps. Ensure compliance with plumbing codes for your old system and secure the necessary permits. Validate all system gas line sizing is appropriate for your gas water heater and electric models.
Schedule an inspection by your plumber who is professional afterwards to test for leaks and ensure all components were installed correctly. Reputable plumbers also service systems every 2+ years to maintain safety and performance.
Although you may handle minor repairs yourself, full installations pose serious risks without the correct licensing, experience, and tools.
Installing hot water systems is a complex process best left to qualified professionals, however, installing water heaters may be attempted by handy homeowners if strictly adhering to safety protocols. The main steps include tending to your water tank:
Switch off the power and water supply before attaching a new valve to the unit. Consider when securing your new tank’s position within your hot water system, this step safeguards against leaks or electrocution.
Remove all pipe fittings, drain valves and discharge pipes connected to your water unit to prepare for the installation of new components. Carefully extract from mounting position without spilling remaining water.
Anchor provided mounting brackets onto wall studs or floor according to instruction manual specifications, allowing room for water lines and gas connections.
Gently position the new water heateras onto the mounting bracket, taking care not to damage attached water lines or components.
Be careful not to cross-thread fittings and verify that all necessary adapters, unions and isolation valves are in place.
Install all valves and set up the system, making sure to correctly size pressure relief and isolation valves in accordance with best practices.
Make sure the plumbing and electrical work, including the wiring and conduit for heating elements, is connected correctly, if relevant.
Open all cut-off valves and purge all air from plumbing lines. Activate the water heater per manufacturer startup instructions.
Check all newly installed fittings thoroughly for leaks during initial operation of both hot cold water supplies. Verify proper water pressure and temperature.
Professional replacement of an old water heater requires careful consideration and typically takes more than 2-3 hours. DIYers should allow significantly more time to ensure safe, leak-free functionality when managing your own water heater installation.
