Comparing Tankless vs. Storage Water Heaters: Which Is the Best for Filipino Homes?

Hot water is essential for a comfortable Filipino household. However, with various water heater options available, picking the right one can be confusing. Two main contenders dominate the market: tank-type and tankless water heaters. Understanding their distinct advantages and disadvantages will help you pick the best water heater Philippines that aligns with your needs and budget.

Storage Water Heaters

Storage water heaters, also known as tank-type heaters, have been the traditional choice for Filipino homes for decades. They function by continuously heating and storing a reservoir of hot water in a tank.


  • Lower upfront cost: Storage water heaters are generally cheaper to purchase and install compared to tankless models.
  • Readily available hot water: Since hot water is constantly stored, you won’t experience any wait time for your shower to heat up.
  • Simpler installation: They typically require less complex installation and can often connect to existing plumbing systems.
  • Works with low water pressure: Storage heaters function well even in areas with fluctuating or low water pressure.


  • Energy inefficiency: Since they constantly maintain a hot water supply, storage heaters can be less energy-efficient than tankless models, leading to potentially higher electricity bills.
  • Limited hot water: The available hot water is limited to the tank’s capacity. Large families or those with frequent hot water usage might experience running out during peak times.
  • Occupies space: These heaters require floor space to accommodate the tank, which might be a concern in smaller bathrooms.
  • Standby heat loss: Even with insulation, storage heaters experience some heat loss over time, further impacting energy efficiency.

Tankless Water Heaters

Also known as instantaneous or on-demand heaters, tankless water heaters are a relatively new technology gaining popularity in the Philippines. Unlike storage models, they don’t store hot water. Instead, they heat water only when needed, activated by a flow sensor when you turn on the faucet.


  • Energy efficiency: Since tankless heaters heat water on demand, they can be significantly more energy-efficient compared to the storage model—potentially reducing your electricity bill.
  • Endless hot water supply: As long as there’s a water source and fuel supply, tankless heaters can provide an uninterrupted stream of hot water, eliminating the worry of running out.
  • Space-saving design: Tankless heaters are compact and wall-mounted, clearing valuable floor space in your bathroom.
  • Longer lifespan: With no tank to maintain, tankless heaters might have a longer lifespan compared to storage models.


  • Higher purchase price: Tankless water heaters have higher upfront costs than storage models.
  • Installation complexity: They might require additional plumbing modifications or upgrades to gas lines and electrical wiring, especially for gas-powered models.
  • Lower flow rate: Tankless heaters may not be suitable for multiple hot water applications simultaneously, such as running a shower and dishwasher simultaneously.
  • Reliance on water pressure: Tankless heaters require a minimum water pressure to function efficiently, which might be an issue in areas with low water pressure.

Choosing the Right Water Heater for Your Filipino Home

The best water heater for your home depends on your household’s specific needs and priorities. Here’s are some factors to consider:

  • Budget: If the shower heater price is a major concern, a storage water heater might be a better choice.
  • Space: A tankless heater is the way to go if your bathroom space is limited.
  • Hot water usage: A tankless heater with a high flow rate is ideal for large families or those with high hot water usage.
  • Energy efficiency: If saving on electricity bills is a priority, a tankless heater offers long-term cost benefits.

By carefully and thoroughly weighing the pros and cons of tankless and storage water heaters, you can make an informed decision and select the perfect option to keep your Filipino home well-supplied with hot water for years.
