Facing Gas Heater Challenges?

We've identified 3 common concerns that homeowners in Singapore may encounter with their gas heaters, along with potential solutions.

1. Gas heaters have low water pressure

Why does this only happen in Singapore and not overseas?

In many other countries, gas heaters typically run on natural gas and employ advanced technology. In contrast, gas heaters in Singapore utilise town gas, which has a smaller market presence. Consequently, gas heaters in Singapore tend to have less sophisticated technology and lower performance levels.

Here is an example:

Town Gas Heater (Singapore)

  • Technology

    Low tech models due to small international market presence.

  • Fewer Protection Features

    Basic tech, internal alarm, no external notification features.

  • Small Suction Fan

    Must be installed outdoors, further away from the shower point. Longer time to get hot water.

  • Limited Burner Performance

    Low water pressure, results in inconsistent hot water temperature.

  • 5 Year Average Life Span
  • Low Noise Control

    Can hear heater in operation at yard.

Natural Gas Heater (overseas)

  • Technology

    High tech, advanced models due to large international market presence.

  • Advanced Alarm Protection

    High security measures against gas leaks, can link direct to fire department.

  • Powerful Suction Fan

    Can be installed indoors, closer to the shower point. Short time to get hot water.

  • High Burner Performance

    High water pressure, consistent hot water temperature.

  • 10 Year Average Life Span
  • Advanced Noise Control

    Silent operation <40dB.

Low water pressure results in cold-hot-cold temperature. Why?

Water heaters fall into two categories:
  1. Instant heaters, which are pressure reducing
  2. Storage heaters which are non-pressure reducing
Gas heaters in Singapore are generally categorised as instant heaters, which reduce water pressure.

When using an instant gas heater, fluctuations in water temperature can occur. For instance, if someone in the kitchen turns on the hot water while you are showering, both of you will experience a drop in hot water pressure.

➡️ A drop in hot water pressure will cause your shower to get colder.

➡️ When another hot water source like the kitchen tap gets turned off, hot water pressure increases and your shower gets hotter.

A typical household has several hot water users. If someone is using the kitchen or another bathroom at the same time, these hot water pressure changes will cause the cold-hot-cold temperature fluctuations.

Solution:

To address this issue, consider replacing your gas heater with a storage heater, which provides higher water pressure and greater temperature stability.

2. Excessive Cold Water Wastage

Gas heaters often require installation at a distance from indoor areas due to safety concerns related to gas leaks.

As a result, it takes a considerable amount of time for the hot water to reach the shower head. This means that you need to run the cold water out of the pipes before hot water finally reaches you.

Solution:

Shift your heater indoors, closer to the shower point. Note that relocating your water heater while you are living in the house can be both messy and costly. It is advisable to do this if you are planning to do a renovation. 

3. Gas heaters are expensive

The price of a gas heater ranges from $180 to $1800. It is advisable for owners not go for the cheapest model unless they are single users as the water pressure is lower. The higher the price, the better the water pressure.

Solution:

One way to bring down your cost is by switching to a storage heater. Storage heaters have been around for longer, and their widespread use has brought its average cost down.

This transition is a practical and cost-effective alternative that may help you avoid substantial upfront expenses. Here's how to get it done: How to convert gas to storage heater.

With this knowledge, we aim to provide you with a balanced perspective on the operation of both types of heaters in Singapore.

I hope you found the potential solutions for addressing these challenges useful! 

Gas Heater FAQ

Are gas heaters more energy saving than electric heaters?
The operational costs of gas heaters are comparable to those of electric heaters. Substantial savings become evident when using renewable energy heaters, such as: A comparison on energy saving water heaters may be found here.
Installing a pressure pump in your home may increase your water pressure but this is not legal in Singapore. This is because a pressure pump can draw water pressure away from your neighbours.

If all your neighbours are experiencing water pressure problems, it is advisable to contact your Town Council or MCST for a better solution.
