Few modern conveniences are as indispensable as hot water. From morning showers to dishwashing and cooking, day-to-day life relies heavily on the availability of instant hot water. If you’re considering upgrading or replacing your hot water system, you’ll find yourself faced with a plethora of options, including instant hot water systems. However, choosing the right one for your home can be a daunting task. To help you make an informed decision, here are five key factors to consider when selecting an instant hot water system.
Type of Instant Hot Water Systems
There are two main types of instant hot water systems: tankless (on-demand) and point-of-use. Consider where you need hot water most frequently to determine which type is right for you.
- Tankless – These systems heat water on demand, providing a continuous supply of hot water without the need for a storage tank. They’re an energy-efficient choice because they only heat water when it’s needed. Tankless systems are best suited for homes with high hot water demands and those looking to save on energy bills.
- Point-of-Use – Point-of-use instant hot water systems are smaller and designed to provide hot water to a specific location, such as a single faucet or shower. They’re cost-effective and efficient for small-scale hot water needs, such as in bathrooms or kitchens located far from the main water heater.
Energy Efficiency
Energy efficiency is a crucial factor when selecting an instant hot water system. Tankless systems are generally more energy-efficient than traditional tank-style heaters because they don’t continually heat a large volume of water. However, there can be variations in efficiency within the tankless category, so it’s important to compare different units before making your choice.
Flow Rate & Temperature Rise
The flow rate and temperature rise of an instant hot water system are important considerations to ensure it will meet your household’s hot water demands. The flow rate is the amount of hot water the system can deliver per minute, while temperature rise is the amount by which the system can increase the temperature of the incoming water. Calculate your household’s peak hot water demand and select a system that can meet or exceed it. Keep in mind that colder climates may require a higher temperature rise.
Installation Requirements
Consider the installation and space requirements of your chosen instant hot water system. Tankless systems are generally more compact and can be mounted on walls or installed in small spaces. However, they may require specific venting and gas line requirements, so it’s essential to consult with a professional installer to determine if your home can accommodate the system of your choice. Point-of-use systems are typically easier to install, but they serve a limited area.
Maintenance & Warranty
Like any household appliance, your instant hot water system will require maintenance and may need occasional repairs. Research the maintenance requirements for the system you’re considering and check if the manufacturer offers a warranty. A good warranty can provide peace of mind and save you money on potential future repairs.
