Is your water heater not keeping up with your needs, leaving you to take cold showers on busy mornings or with unexpectedly high energy bills? It might be time to consider upgrading your unit.

In this article, we’ll be guiding you through the essential factors to consider when upgrading your water heater. Once you understand these key aspects, you'll be equipped to make a decision that enhances your home's efficiency and comfort without unnecessary complications.

Fuel Type

Choosing the right fuel type for your water heater will depend on availability, cost, and personal preference. In New Zealand, options typically include electricity, natural gas, and solar power. Electric heaters are widely used due to their availability and lower upfront costs, but they can be more expensive to operate than gas heaters. Natural gas is a good option if it's readily available in your area, as it offers lower running costs and less environmental impact. Meanwhile, solar water heaters require a higher initial investment but can provide significant energy savings over time because they utilise New Zealand’s abundant solar resources.

Energy Efficiency



When getting a new water heater, energy efficiency is a major consideration due to its direct impact on your electric bills and environmental footprint. Look for a water heater with a high Energy Star rating. These models might cost more upfront but typically lead to significant savings by using less power. This is not only good for your wallet, but also better for the environment because of lower overall greenhouse gas emissions.

Type of Heater

Water heaters mainly come in two types: tank storage and tankless. Tank storage heaters store and heat water in a large tank so they can offer a ready supply when needed. However, they can lose heat over time and thus require more energy to keep the water at a desirable temperature. Tankless water heaters, on the other hand, heat water directly without the use of a storage tank. Also called on-demand heaters, tankless water heaters are more energy-efficient but usually have a higher initial cost.

Capacity

The capacity of your water heater should match your household’s demand for hot water. A unit that’s too small will run too frequently, struggle to meet the demand and wear out prematurely. Conversely, a unit that’s too large will incur unnecessary energy costs. The key is to estimate your peak water usage and choose a water heater model that can handle your busiest times without wasting energy. For example, a family of four might consider a tank with at least a 180-litre capacity to ensure a continuous supply during morning and evening routines.

Cost

The cost of a new water heater encompasses more than just the purchase price; it also includes installation and ongoing operating expenses. Initially, more efficient models and those with advanced technologies like tankless systems may have higher price tags. However, it's important to consider the long-term savings that come from reduced energy consumption. You may also want to investigate potential rebates and incentives available for installing energy-efficient appliances in New Zealand, which can help offset upfront costs.

Installation Requirements

Before purchasing a new water heater, you must consider the specific installation requirements. Some systems may require special setup procedures or modifications to your home's existing plumbing or electrical infrastructure, such as those that run on gas or involve advanced technology like solar panels. Mains Plumbers can assess your home's current setup and recommend the most suitable water heater type, as well as handle all aspects of the installation process. Our expertise ensures that the system you choose is compatible with your home’s layout and local building codes, providing optimal performance and safety.

Environmental Impact



As a responsible homeowner, you’ll also need to consider the environmental impact of your new water heater. New Zealand's commitment to reducing carbon emissions means it’s more important than ever to choose a system that aligns with this goal. In this regard, solar water heaters and highly efficient gas or electric models can dramatically decrease the amount of CO2 your home produces. Additionally, opting for a water heater with a longer lifespan and recyclable components can further reduce its environmental footprint.
