How To Pick The Best Electric Hot Water System

Several options are available when choosing a new hot water system for your home. Electric hot water systems have gained popularity due to their efficiency, reliability, and ease of installation.

Here’s a guide on picking the best electric hot water system that suits your needs.

Determine Your Hot Water Requirements

Assessing your hot water usage is crucial before diving into the details of different electric hot water systems. Consider factors such as the number of people in your household, how much hot water is used, the frequency of hot water usage, and the size of your property.

This information will help you determine the capacity and type of electric hot water system that will meet your demands effectively.

Understand the Types of Electric Hot Water Systems

There are three types of electric water heaters: storage tank systems, instantaneous systems, and heat pump systems.

  • Storage tank systems store hot water in a tank and are suitable for households with a consistent demand for hot water.
  • Instantaneous systems, also known as continuous flow systems, heat water on demand, making them ideal for smaller households or locations with limited space.
  • Heat pump systems are highly energy-efficient and utilise ambient heat from the surrounding air to heat the water.

Consider Energy Efficiency

An electric water heater and gas hot water systems are generally more energy-efficient than others. However, choosing a system with high energy efficiency is essential to minimise running costs and reduce greenhouse gas emissions.

Look for systems, such as solar hot water systems(if suitable), that meet minimum energy performance standards and have a good energy rating. Heat pumps and solar water heaters are known for their energy efficiency.

Assess Installation Requirements

Different electric hot water systems have varying installation requirements. Storage tank systems are typically installed indoors, while a heat pump and a solar hot water system can be installed outdoors.

Consider the available space in your property and the venting requirements before deciding. Electric instantaneous water heaters or compact storage tank systems might be more suitable if you have limited space. Compact Storage systems can be installed in cupboards for efficient space usage.

Compare Running Costs

Running costs can significantly impact your monthly hot water costs, so comparing the running costs of different electric hot water systems is crucial. Consider factors such as electricity tariffs, peak and off-peak electricity options, and the system’s energy efficiency.

Though a traditional solar water heater is known for its low running costs, electric hot water systems can be a good alternative if unavailable in the areas, making them attractive options for cost-conscious homeowners.

Consider the Size and Capacity

The size and capacity of the electric hot water system should align with your household’s hot water demands. Consider the number of bathrooms, hot water outlets, gas water heaters and hot water usage frequency.

A larger household will require a system with a higher capacity to ensure an adequate hot water supply. On the other hand, a smaller household or a property with limited hot water outlets can opt for a system with a lower capacity.

Here are the general recommendations:

  1. For a single person or a couple: A 50-80 litre electric hot water system is typically suitable. This size is sufficient to meet the hot water needs of a smaller household.
  2. For a small family of 3-4 people: A 125-160 litre electric hot water system is commonly recommended. It provides an ample supply of hot water for daily use.
  3. For larger households or families with 5 or more people: A 250-400 liter electric hot water system is often required to meet the increased demand for hot water.

It’s important to note that these sizes are general guidelines, and the specific hot water requirements may vary depending on individual usage patterns and preferences. It’s advisable to consult with a professional plumber or electrician to determine the most suitable size for your particular needs.

Evaluate Durability and Reliability

A reliable hot water system ensures a consistent hot water supply and avoids frequent breakdowns. Read customer reviews and check the warranty period offered by the water heaters manufacturer. Look for reputable brands that produce durable and reliable electric hot water systems.

Why You Need an Expert to Install the Best Electric Hot Water System

Installing a hot water system, especially an electric one, requires careful planning and expertise to ensure optimal performance, safety, and longevity.

While it may be tempting to attempt a DIY water heater installation, seeking the assistance of a licensed electrician is required by law. Here’s why you need an expert to install the best electric hot water system:

Compliance with Regulations

Electrical and water heaters and plumbing installations must adhere to specific regulations and building codes. A professional installer is well-versed in these regulations and will ensure that your electric hot water system installation meets all the requirements.

This includes obtaining required permits and providing proper rewiring home services, plumbing connections, and ventilation.

Safety Considerations

Hot water systems involve working with electricity, water, and potentially gas (in some models), which can be dangerous if improperly handled. An expert installer understands the safety protocols involved in the installation process.

They will take appropriate measures to prevent electrical shocks, water leaks, natural gas well leaks, and other hazards that could pose risks to your household members.

Proper Sizing and Capacity

Determining the right size and capacity of electric hot water heaters is crucial to meet your household’s hot water demands.

An expert installer will assess your hot water requirements and consider the number of occupants, water outlets, and usage patterns to recommend a unit of appropriate size and capacity. This ensures you have enough hot water without wasting energy or experiencing insufficient supply.

Professional Advice and Product Selection

With their knowledge and experience, professional installers can provide valuable advice on selecting the best electric hot water system. They stay updated with the latest technologies, features, and energy-efficient options.

By considering factors such as your budget, energy requirements, available space, and desired functionalities, they can guide you towards choosing the most suitable heat pump hot water system.

Warranty and Service

Most reputable electric hot water system manufacturers require professional installation to maintain warranty validity. Hiring an expert installer ensures the continuous flow system installation is done correctly and according to the manufacturer’s guidelines.

In case of any issues or repairs, having a professional installation allows you to take advantage of the warranty and ensures that the system can be serviced without complications.

Long-Term Cost Savings

While professional installation of electric hot water or gas storage systems may come with an upfront cost, it can lead to long-term cost savings. An expert installer will optimise the installation for energy efficiency, reducing electricity bills and minimising heat loss.

They can also recommend additional measures like insulating pipes or using timers to enhance the system’s efficiency further. Additionally, a properly installed system is less likely to experience breakdowns, saving you from costly repairs and replacements in the future.

Time and Convenience

Installing an electric hot water heater involves multiple steps, including electrical connections, plumbing work, and potentially configuring control panels. Hiring an electric or gas hot water expert saves time and effort that would otherwise be spent researching, gathering tools and materials, and going through trial and error.

Professionals have the necessary skills and tools to complete the installation efficiently and effectively, ensuring that you have hot water available without unnecessary delays.

Key Takeaway

In conclusion, choosing the best electric hot water system involves considering your hot water requirements, energy efficiency, installation requirements, running costs, size, capacity and durability.
