Convert: Gas to Storage Heaters

Are you planning to fix a storage heater in place of your existing gas heater? Use this 5-step guide to help you out.

1. Provide details of existing gas heater

Send a photo of your gas heater to us. Instead of just taking a close up of the heater, include also the space around it. Useful photos include, the top of aircon ledge, space available at aircon ledge, yard or balcony. This will be helpful for determining the position of your new storage heater.

Gas heaters are usually installed outdoors in case there is a gas leak. Storage heaters should be installed indoors or in a sheltered area as they are electrical appliances and are not weatherproof.

Other bits of helpful information you can provide:
– Is there a dedicated 15A switch available nearby?
– Have other neighbours done similar installations?
– Does your building management approve of the works?

2. Contact your building management for approval

Once you have confirmed a location for the new storage heater, contact MCST for approval. You may be asked to fill in an application for renovation works. HDB owners usually skip this step as their heaters are installed indoors.

HDB: The town council does not allow heaters to be fixed at the air con ledge.
Private: Most MCST will approve the changes, but it is possible to get rejected. Please seek approval before proceeding.

3. Terminate gas supply

If the storage heater can be installed close to your gas heater, we will reconnect your water pipes from the gas to the storage heater. The gas supply will simply be shut off at the lever. Do call CityGas later to fully terminate the heater gas supply or you may still be charged.

We have heard from homeowners that Citygas is unwilling to terminate the supply and are asking for many supporting reasons and your IC numbers. This is similar to the termination of a mobile phone line. It is not necessary to give out so much information.

Removal of gas heater
The removal of the gas heater is not necessary, but if you want to do so for aesthetic purposes, please contact CityGas or their recommended installers.

Note: For your safety, please do not perform an unauthorised uninstallation of your gas heater. As gas is quite volatile, they should only be handled by trained professionals.

4. Arrange to install the storage heater

If you choose to skip the termination of gas supply and removal of gas heater, you may skip step 3 in the diagram below.

For those who need to contact Citygas: Once you have a removal appointment, you may proceed to arrange for the installation of your new heater. Try to give a 2 working day buffer for any uninstallation or installations. If you plan things right, the disconnection of gas can be done in the morning and the installation of the new heater on the afternoon of the same day (2pm onwards). This will minimize hot water downtime.

5. Determine heater and panel location

Every ledge area is different. We will propose the best location for the heater and control panel. The maximum cable length for the control panel is 2.5m. This panel will not be installed at the location of the existing gas heater panel.

Tip: The panel serves to program your heater at the start. After it is set, the main on-off control is the heater switch. There is no need to refer to the panel and adjust it daily.

That’s it!

There you have it, a 5-step checklist that will hopefully give you a clearer picture of the process. If you have any other questions, simply reach out to us over WhatsApp.
