Solar Hot Water System Supplier
Looking for a solar hot water system supplier for a new installation, old system replacement or capacity upgrade?
Service Junction helps with solar hot water system sales enquiry, ETC and FPC model guidance, LPD capacity selection, roof-space checking, installation support, low-heating complaints, leakage checking, glass tube replacement, tank inspection and maintenance support.
What a Solar Hot Water System Supplier Should Help With
A solar hot water system supplier should not only sell the unit. The right supplier should help you understand the capacity, system type, roof requirement, plumbing need and future service support before purchase.
Important supplier guidance includes:
- ETC or FPC system selection
- 100 LPD, 150 LPD, 200 LPD, 300 LPD or higher capacity guidance
- Roof-space and sunlight check
- Tank and collector placement
- Plumbing route planning
- Hot water outlet and cold water inlet checking
- Installation material requirement
- Service and spare support
- Old system replacement guidance
Wrong selection can cause low hot-water output, poor flow, leakage, repeat service complaints or extra installation cost.
ETC and FPC System Supply
Solar hot water systems are commonly available in ETC and FPC types.
ETC systems use evacuated glass tubes to absorb solar heat. They are commonly selected for domestic hot-water needs and are available in multiple LPD capacities.
FPC systems use flat plate collectors with absorber plates, insulation and glass covering. They may be preferred when a flat collector design, stronger panel structure or specific water condition requirement is important.
The right system depends on water quality, pressure condition, usage level, roof space, budget and maintenance preference.
Choosing the Right LPD Capacity
LPD means litres per day. Capacity selection is one of the most important parts of buying a solar hot water system.
Common capacity choices include:
- 100 LPD for small family use
- 150 LPD for medium domestic use
- 200 LPD for higher home usage
- 300 LPD for larger homes or shared usage
- 500 LPD and above for heavy hot-water requirement
A small system may not provide enough hot water during peak usage. A larger system may need more roof space, stronger installation planning and higher investment.
Supplier Check Before Quotation
Before giving a proper quotation, the supplier should understand the actual site condition and usage requirement.
Important details include:
- Number of users
- Daily hot-water requirement
- Number of bathrooms
- Morning or evening usage pattern
- Roof space
- Sunlight exposure
- Shade from nearby objects
- Plumbing distance
- Water pressure
- Existing hot-water line condition
- Whether old system removal is needed
- Whether electrical backup is required
A quotation without these details may not reflect the final installation requirement.
Roof and Installation Requirement
Solar hot water system supply should be connected with proper installation planning.
Before installation, check:
- Open roof area
- Safe roof access
- Roof strength
- Stand placement
- Collector direction
- Tank position
- Pipe route to bathroom
- Cold water inlet line
- Hot water outlet line
- Overflow line
- Air vent arrangement
- Future service access
A good product can still perform poorly if installed in shade, placed wrongly or connected with poor plumbing.
Tank, Collector and Material Check
A solar hot water system usually includes a storage tank, collector system, support structure, pipe connections and accessories.
During supplier discussion, ask about:
- Tank capacity
- Tank material
- Tank insulation
- Collector type
- Tube or panel size
- Stand material
- Inlet and outlet connection
- Pressure suitability
- Electrical backup option
- Warranty terms
- Service support
- Spare availability
These details help compare systems properly instead of choosing only by price.
New System Supply vs Old System Replacement
A new installation is different from replacing an old solar water heater.
For old system replacement, the site should be checked for:
- Existing tank condition
- Old stand condition
- Broken glass tubes
- Leakage in old plumbing
- Roof damage near the system
- Existing pipe route
- Whether old capacity was enough
- Whether new system needs different placement
- Removal access for old unit
If the old plumbing is weak, the new system may also face leakage or poor hot-water flow unless correction is done.
Low Heating After Installation
Low heating after installation may happen because of site, usage, plumbing or system selection issues.
Possible reasons include:
- System capacity lower than demand
- Shade on collector or tubes
- High hot-water usage at night
- Cloudy weather
- Bent or blocked connecting pipes
- Air trapped in tank or line
- Cold water mixing with hot water line
- Plumbing leakage
- Dust on collector surface
- Broken glass tube
- Incorrect pipe routing
A supplier with service support should help check these issues instead of only selling a new unit.
Leakage and Service Support
Leakage can happen from tank fittings, pipe joints, glass tube seals, valve connections, overflow line, hot water outlet, cold water inlet or old plumbing.
Before buying, ask whether service support is available for:
- Leakage checking
- Glass tube replacement
- Tank inspection
- Valve replacement
- Pipe connection correction
- Stand inspection
- Low hot-water output
- Air lock checking
- Maintenance visit
- Old system replacement
After-sales support is important because solar hot water systems are roof-installed and connected to plumbing lines.
Price Factors for Solar Hot Water System Supply
Solar hot water system price changes based on:
- ETC or FPC type
- LPD capacity
- Tank material and insulation
- Collector type
- Stand and support structure
- Roof height and access
- Plumbing distance
- Pipe and fitting requirement
- Electrical backup option
- Old system removal
- Installation labour
- Service support and spare availability
The final price should be confirmed after checking requirement and site condition.

FAQs
What does a solar hot water system supplier provide?
A supplier may help with system selection, LPD capacity guidance, ETC or FPC model choice, installation planning, roof-space checking, service support and replacement guidance.
Which is better, ETC or FPC solar hot water system?
ETC and FPC both can be suitable depending on water quality, usage, pressure condition, roof space and budget. The right choice should be made after checking the requirement.
What LPD capacity should I buy?
Capacity depends on number of users, bathrooms, daily hot-water demand and usage timing. Common options include 100 LPD, 150 LPD, 200 LPD, 300 LPD and 500 LPD.
What should I check before buying a solar hot water system?
Check roof space, sunlight exposure, plumbing distance, tank placement, water pressure, service access, capacity requirement and installation material needs.
Can an old solar water heater be replaced?
Yes. Old systems can be replaced if the tank is damaged, tubes are broken, heating is weak, stand is unsafe or repair cost is high.
Does supplier support include installation?
Installation support should be discussed before purchase. Installation may include stand placement, tank setup, collector fitting, pipe connection, overflow line and working check.
Why does a new solar system give low hot water?
Low hot water may happen due to wrong capacity, shade, high usage, cloudy weather, pipe issue, air lock, leakage, cold-water mixing or installation problem.
What details should I share for a quotation?
Share number of users, hot-water requirement, roof photo, existing system photo if any, preferred capacity, plumbing distance and whether old system removal is required.
