HDB flats and condos choose from the same range of water heaters. What decides the right model is how many people shower, how many bathrooms need hot water, how strong your water pressure is, and how much space you have. This guide walks through each one and points to the 707 and Champs models that fit.
Quick picks
| Your situation | A good fit |
|---|---|
| One or two people, one shower, limited space | A slim instant heater, such as the 707 Luxton, 707 Briston or Champs Astra |
| Weak water pressure or you want a rain shower | An instant heater with a booster pump, such as the 707 Kingston or Champs Vesta |
| Steady temperature matters most | The 707 Queenston with thermostatic control |
| Small household, hot water at more than one tap | A 15-litre storage heater, such as the 707 Dalton 15 or Champs SA15 |
| Family showering one after another | A 30–35 litre storage heater, such as the Champs SA30 or 707 Kensington 35+ |
1. Instant or storage?
An instant heater warms water as it flows, so there is no waiting and no tank. It usually serves one shower and is mounted next to it. A storage heater keeps a tank of hot water ready and can supply several outlets at a steady temperature, but needs time to heat up and takes more space. Our storage vs instant guide compares them in detail.
If you are replacing a heater, staying with the same type is often the simplest option, because the piping and wiring are already set up for it. Switching is possible, but tell us when you call so we can plan the installation.
2. How many people and bathrooms?
For an instant heater, plan on one heater per shower. For a storage heater, the tank size decides how many back-to-back showers you get before it needs to reheat:
- 15 litres, for one bathroom or a small household: 707 Dalton 15, Champs SA15
- 25 litres, for longer showers or a bigger household: 707 Dalton 25, 707 Kensington 25+
- 30 to 35 litres, for families showering one after another: Champs SA30, 707 Kensington 35+
3. How strong is your water pressure?
Instant heaters need a minimum flow of water to switch on, typically 2 to 3 litres a minute. If your shower is weak, for example on the top floors of a block close to the rooftop water tank, choose a model with a built-in booster pump. Our guide to rain shower heaters for low water pressure compares the options.
4. How much space do you have?
- Slim instant heaters suit small bathrooms: the Champs Astra is 70mm deep, the 707 Luxton 85mm and the 707 Briston 91mm.
- Round storage heaters like the 707 Kensington 25+ and 35+ support multi-position installation, which gives more options when ceiling space is limited.
- Square storage heaters like the 707 Dalton are compact and easy to service.
5. Energy efficiency
Look at the tick rating on the energy label: more ticks means a more efficient heater. The 707 Briston and Luxton and the Champs Legend and Astra are rated 4 ticks. Among storage heaters, the 707 Kensington 25+ is rated 3 ticks.
6. Comfort extras
- Rain shower sets: 707 Kingston, Champs Legend, Vesta, Virgo Ultra and Auriga Ultra
- Massage shower sets: 707 Protek (3-way) and Queenston, Champs Astra and Wish
- HydroJet Ag+ shower head with a silver-ion coating: 707 Briston and Luxton
- Thermostatic temperature control: 707 Queenston
