For optimal efficiency, hot water systems should be installed as close as possible to frequently used hot water outlets like kitchens, bathrooms and laundry rooms. Proper ventilation, drainage, maintenance access and safety clearances must also be considered when determining location.
When installing a new hot water unit or replacing an old one, ensuring the right installation location is crucial for efficiency, safety, and compliance.
The type of system installed - whether gas, electric, heat pump or solar - must be taken into account along with factors like available space, ventilation, accessibility for future maintenance, and proximity to existing plumbing.
The optimal location ensures your hot water system operates at maximum efficiency to reduce energy bills while meeting all regulations.
Gas, electric, solar, and heat pump hot water systems are tailored to various requirements. Gas water heaters directly provide heated water using natural gas or LPG. Electric storage water heaters employ elements to keep water at a consistent temperature in the tank.
Solar water heaters utilise thermal collectors and storage tanks to convert sunlight into heat. Heat pumps transfer ambient heat from the air to water in a tank, effectively maintaining temperature. Sizing a hot water system requires considering fuel type, climate, household size, usage patterns, available space, and the shut off valve placement for safety.
An undersized unit may fall short on fulfilling water needs, whereas oversized ones lead to energy and monetary waste. Our team can help assess your specific requirements and recommend a new system that’s suitably sized, whether it’s a tankless continuous flow model or a conventional storage tank system.
Proper sizing ensures efficiency and facilitates the transition of your hot water system to accommodate your home’s water needs.
A gas hot water system stands out for its cost-effectiveness and reduced environmental impact. Burning natural gas or LPG directly heats water stored in an insulated tank, making gas systems up to 30% cheaper to run than electric. Additionally, they emit fewer greenhouse gases.
Proper ventilation is a critical aspect, particularly for gas hot water system installations. Exhaust flues remove combustion byproducts while intake vents supply fresh air for efficient burner operation. Both flues and vents need an unobstructed path outdoors.
New installations can also consider placing tanks close to existing gas lines wherever feasible to minimise pipe runs.
Our licensed plumbing and electrical professionals help select a location for your water system in compliance with regulations.
Electric hot water systems heat water using internal electric heating elements in an insulated storage tank. Electricity directly powers the elements to heat the water, making proximity to an adequate electrical supply critical when determining installation locations.
Place electric water systems in shaded areas to prevent direct sunlight exposure and ambient heat, thereby regulating temperature for optimal efficiency. Ensure sufficient clearance around the new unit for ventilation and to access components during maintenance.
Insulating electric hot water system tanks is also recommended as this greatly improves efficiency and reduces standby heat losses. Position tanks away from living areas to minimise noise, ensuring ease of access for future service repair. Ensure there’s adequate space to safely drain and replace units, which extends the lifespan of your hot water system.
Solar hot water systems use roof-mounted solar thermal collectors paired with insulated storage tanks to harness heat from sunlight. The solar panels absorb the sun’s energy, heating fluid that transfers heat to water held in the tanks.
For solar water systems, consider your roof’s orientation, pitch, and strength; ideally, north-facing for consistent sunlight exposure in Australia. Roof spaces need to safely support the panel weight long-term.
Situate the new tank near existing plumbing to efficiently deliver water and replace the old tank. Ensure unobstructed solar access, as trees or nearby tall structures can significantly reduce system performance. Consider ease of access for future repairs or panel cleaning.
Heat pump systems are highly energy efficient, drawing in ambient heat to warm the water within an insulated tank. These models stand out for their energy efficiency, with lower running costs compared to standard electric units.
When determining installation location, ensure adequate airflow around the heat pump unit. Unlike solar hot water systems, hot water heaters do not require access to direct sunlight but should not be positioned in overly shaded areas. Provide sufficient clearance for ventilation and prevent recirculation of cooled discharged air.
Situate away from living spaces to minimise noise disturbances and allow room for servicing access. Place the storage tank close to existing plumbing connections for efficient water delivery. Efficient hot water storage is crucial, and heat pump systems work most efficiently in warm environments, so external installations require weatherproofing.
Strict regulations and standards govern hot water system installations to ensure safety and compliance. Key safety and compliance requirements include:
Installers must also ensure your water heater adheres to state plumbing codes and local council regulations to qualify for hot water rebate opportunities. An appropriately qualified technician will make sure your new hot water system meets all necessary standards to qualify for valuable hot water rebates.
When determining the optimal location to install a hot water system, your business should consider both indoor and outdoor options carefully based on the type of system. Key factors include:
Outdoor hot water systems require weatherproofing to safeguard components such as heat pumps and electronics. Indoor sites must safely direct flues to the exterior. Ensure all Australian Standards, state plumbing codes and local regulations are fully satisfied regardless of the position.
When installing a hot water system, ensuring future accessibility for maintenance and repairs is crucial. The system should be positioned to allow adequate clearances on all sides for a technician to access components and carry out servicing.
While meeting accessibility requirements, installations must still comply fully with Australian Standards, including tempering valve regulations for safety. This includes having tempering valves fitted, relief valves, safe trays beneath tanks, and appropriately directed flue exhaust and ventilation.
Units installed inside should have sufficient space around them to perform visual inspections, anode replacements, element replacements or valve repairs without needing to disconnect pipework or dismantle surrounding cabinetry.
Outdoor installations also need weatherproofing to ensure proper operation while still enabling access doors to open fully, tanks to drain or components like solar panels or heat pump units to be accessed from below and above.
Our team, hot on delivering efficient solutions, considers your specific needs when determining the optimal location for your hot water unit. Well-considered installation positions balance accessibility, longevity, safety and compliance.
Ensuring proper ventilation is crucial for gas hot water systems to operate safely and at peak efficiency. Gas combustion produces carbon monoxide and other byproducts that must be safely directed outside through an exhaust flue.
Flues remove these dangerous gases, and youll need intake vents to supply fresh external air to the burner for complete combustion. Install new venting systems so that flues and vents have a direct, unobstructed path to the outdoors.
Careful consideration of ventilation needs is vital when determining installation locations. Positions must allow exterior venting to be installed to all legal requirements. There should also be adequate clearances for ventilation grilles beneath tanks or around units.
Even when situated outdoors, correct flue installations are mandatory. Our team guarantees that your hot water system’s location adheres to Australian ventilation standards, mitigating risks associated with exhaust gases.
The location of the hot water system in your house in relation to the fixtures and taps it serves is an important efficiency consideration. Long pipe runs from the water heater to outlets can vary in impact, resulting in increased heat losses and slower delivery.
Positioning your hot water supply system close to bathrooms, kitchens and laundry areas minimises piping distances for faster supply. Keeping pipe lengths as short as possible also reduces wastage from water cooled down in long pipes before reaching your hot water tap.
When determining position, ensure adequate access is allowed to connect new hot and cold water supply pipes to existing plumbing with minimal bends for optimal flow. Locating outdoor units adjoining internal walls often enables neater piping runs directly through the wall.
Installing a hot water system requires proper structural support for the unit’s weight, especially important for storage tank systems which can weigh over 100kg when full. Outdoor locations for your hot water system may call for a raised platform or wall-mounting.
Structural integrity must safely sustain the system long-term without risk of collapse. Walls should have wall framing or added bracing to bear loads. Raised stands must not vibrate or sway during operation or high wind events.
Rebated systems may require certification from engineers that the structure meets regulations. Tanks may need tie-downs, restraints or seismic bracing in earthquake-prone regions. Ensure your installer is fully aware of what you need for structural support and addresses these needs for your hot water replacement location appropriately.
Allowing adequate clearances around hot water systems is vital for ventilation, drainage, servicing access and safe operation. Australian Standard AS/NZS 3500.4 dictates minimum clearances based on location.
Indoor units, including your hot water heater inside, require at least 300mm clearances across the front and sides, with 600mm above electric elements. This enables access to components without removing pipework or cabinets.
Systems installed outside need a minimum 500mm clearance on all sides and 2500mm overhead clearance. Wall-mounted external units should have 500mm clearance below, 300mm beside, and 300mm above.
Service access clearances stipulated in AS/NZS 3000 Electrical Installations must also be met for electrical hot water units. Ensure your installer positions your system meeting all mandated clearances for ventilation, drainage, servicing access and safe ongoing use.
When installing a new hot water system, proximity and access to existing plumbing connections is a crucial consideration influencing position. Locating the unit near current pipework minimises modifications required.
Long pipe runs to connect appliances may highten installation costs, increase the risk of leaks from more joints, and result in ongoing efficiency losses due to heat wastage through piping. Adjustments like rerouting sections of pipework may be needed to optimally situate the system.
Outdoor locations adjoining internal walls often allow short, straight pipe connections directly through the wall cavity into existing kitchen or bathroom plumbing. Consider ease of access for future repairs when situating units. Our experts position systems balancing ideal pipe runs with ventilation needs, clearances and regulations.
When installing a hot water system outdoors, key considerations include weatherproofing, security, environmental factors influencing efficiency, access for maintenance and visual appeal.
We ensure hot water systems are fitted with weatherproof measures to shield against rain and dust, preventing corrosion or electrical issues. All access panels must be sealed effectively.
Position tanks on stands securing against high winds. Locate solar heat pump or gas units away from water sprinklers to avoid potential electrical hazards. Consider a fence or cage enclosure for security if visibility from the street.
Ambient air temperature and water use greatly impact pump water heaters operation.
Avoid highly shaded areas to maximise your system’s solar efficiency.
