Choosing the right storage water heater for your Singapore home is a long-term investment. 707’s range is built to balance performance, safety, and running costs — so you never have to compromise.
The storage tank maintains a full reservoir of heated water throughout the day. Whether your household needs a morning shower or an evening rinse, hot water is available the moment you open the tap — no waiting, no cold bursts.
Every 707 storage water heater in Singapore meets and built above the Singapore safety standards. Each unit features thermal cut-out protection, pressure relief valves, and anti-corrosion inner linings as standard.
Modern insulation technology minimises standby heat loss — the primary energy cost of any storage water heater. 707 models use high-density foam insulation to keep water hotter for longer, which translates directly into lower electricity bills for your household.
From compact 15-litre units ideal for a single bathroom to 35-litre tanks that comfortably serve a family of 5, 707 offers capacity options designed for every Singapore home type — HDB flat, condominium, or landed property.
As Singapore’s preferred residential water heater provider for generations, 707 been trusted by Singapore Families. Our customers return not just for the products, but for the reliability of knowing their storage water heater will perform year after year — backed by genuine parts and a responsive service team.
Selecting the correct tank capacity ensures your storage water heater works efficiently without overworking itself or leaving family members short of hot water. Use the guide below as a starting point, then speak with a 707 specialist for a tailored recommendation.
| Household Size | Bathrooms | Recommended Capacity | Best For |
|---|---|---|---|
| 1–2 persons | 1 | 15L | Singles, couples, studio or 2-room HDB |
| 2–3 persons | 1–2 | 25L Popular | Small families, 3-room HDB |
| 3–4 persons | 2 | 30L Recommended | Typical families, 4- or 5-room HDB, condo |
| 4–5 persons | 2–3 | 40L | Larger families, condominiums, landed homes |
* Capacities listed are per bathroom unit. For multi-bathroom homes, a separate storage water heater for each bathroom is generally recommended for consistent pressure and temperature. Consult a 707 installer for a full assessment.
A storage water heater always keeps a full tank of hot water ready, which means electricity is used to maintain that temperature thus it is not as energy efficient as the instant water heater which only use electricity when you use it and no electricity is wasted between uses.
The real-world cost gap is smaller than many expect. 707’s storage water heater uses high-density foam insulation to minimise standby heat loss.
Most units reach the suitable for shower temperature within 20–30 minutes from cold, though a 15-litre tank will heat noticeably faster than a 35-litre one. It is recommended for household to turn off storage water heater when not in use. With the 707’s foam insulation which minimises heat lost, the element only activates briefly to top up heat between uses, keeping running costs low.
For safety reason, it is not recommended to leave your storage heater turned on all the time.
For a well-insulated storage water heater like 707 Kensington+ and Dalton, the standby cost is modest.
A cheaper storage water heater with thinner insulation may cost considerably more to run over its lifetime — making a trusted 707 unit the better investment in the long run.
The right storage water heater size depends on how many people share your bathroom. As a guide, 15L suits one to 2 persons sharing a bathroom; 25L works well for a small family; and 35L suits larger households where back-to-back showers are the norm. The difference between the right and wrong size often comes down to that lukewarm rush-hour shower versus a reliably hot one. That said, every home is different. Speak with a 707 specialist for a recommendation based on your layout, your household size, and how you use hot water day to day.
One storage water heater is generally not recommended for multiple bathrooms. For consistent pressure and temperature at every tap, one unit per bathroom is the standard approach. Sharing a single heater across bathrooms often means uneven heat distribution and pressure drops at peak times, which is the last thing anyone wants on a busy morning. A 707 installer can assess your home layout and design a setup that works properly for every member of the household.
The main difference between the Kensington and Dalton is energy efficiency technology and splash-proof rating. Both are built on 707’s core commitment to safety and long-term reliability, but they serve slightly different priorities.
The Kensington is built for maximum energy efficiency, featuring Whirlflow 2 Technology for faster heating and lower running costs, making it a strong choice for households focused on long-term savings. The Dalton is built with IPX4 splash-proof protection, offering robust, dependable performance at an accessible price point, ideal for families who want proven reliability without compromise.
Both share a Blue Enamel Coated Steel Tank and Blue Enamel Coated Incoloy Heating Element for lasting corrosion resistance, and both carry the SAFETY Mark certification required for sale in Singapore. A 707 specialist can help you decide.
Yes, every 707 storage water heater is fitted with a pressure relief valve as a standard. It is one of the most important safety features on any storage water heater, strongly recommended by Singapore’s Consumer Product Safety Office and required by most manufacturers to validate your warranty. Your installer will confirm it is correctly set during installation, so you can shower with complete peace of mind from day one.
707 storage water heaters carry a 7-year tank warranty, 2 years parts warranty and 2 years on service. All warranty cover is supported by a local customer service centre, so if anything ever falls short, you are not left managing it alone. That level of cover reflects genuine confidence in the product and puts 707 among the stronger warranty offerings in this category. Warranty terms vary by model, so confirm the cover for your chosen unit at the time of purchase.
Yes, a storage water heater is well suited to HDB flats, and 707’s range is designed with HDB homes in mind. Compact models from 15L fit standard HDB bathroom configurations without taking up valuable space, and every unit carries the SAFETY Mark certification required for compliance in public housing. Whether you are renovating a 3-room flat or upgrading a 5-room bathroom, there is a 707 model that fits the space and meets the standard. Your installer will confirm the right fit for your specific flat type.
A storage water heater can run out of hot water if the tank capacity is too small for the number of people using it. With the right unit, it should never happen to your household. Choose a capacity matched to your family size, and the tank replenishes itself continuously, with most units recovering to full temperature within 20 to 30 minutes between uses. If you are unsure which capacity is right, that is exactly what a 707 specialist is here to help with.
