Residential energy-efficient hot water and lighting solutions by ELWA

Instantaneous Electric Hot Water for Your Home

Water heating can represent a significant part of household energy use, which makes the type of system you choose an important consideration. Traditional storage systems heat and hold a set volume of water in a tank. Instantaneous systems take a different approach by heating water as it passes through the unit when you turn on a hot tap.
Instantaneous electric hot water system for residential homes

Our residential electric hot water options are designed around this on-demand approach. A correctly selected instant electric hot water system gives you access to hot water without keeping a large storage tank heated throughout the day. The compact design can also make installation easier in properties where available space is limited.

For homeowners comparing residential hot water systems, this can be useful in kitchens, bathrooms, laundries, apartments and other areas where hot water is needed close to the point of use. Because there is no tank holding a fixed quantity of heated water, you are also not limited by stored capacity in the same way as a conventional system.

Choosing the correct unit is important. The amount of heating required changes according to your location and incoming water temperature, particularly during colder months. Required flow, the number of outlets being supplied and the electrical capacity available at the property also need to be considered.

Our residential instantaneous hot water range includes compact Hotrun models for different applications. We provide personalised guidance to help match the system to your location, expected demand and available electrical supply.

Explore the ELWA Hotrun Range

ELWA brings more than 35 years of experience in instantaneous electric water-heating technology to the Hotrun range. The different models are designed to accommodate varying levels of demand without making product selection unnecessarily complicated.

A Hotrun hot water system heats water when it is required, rather than storing a tank of preheated water. The model and power setting still need to suit the intended application, as performance is influenced by inlet temperature, required flow and available electricity.

The Hotrun X11 can suit kitchen sinks and selected shower applications, while the Hotrun X24 is designed for higher-demand situations involving multiple outlets.

If you are considering an electric instantaneous hot water heater, our team can help you identify which model fits the property instead of simply choosing according to unit size. ELWA’s broader range of energy-saving products and services also brings together our water-heating and lighting expertise in one place. Contact ELWA to know what system is appropriate for your home.

Energy-Efficient LED Lighting for Residential Spaces

Improving residential energy efficiency can also involve something as familiar as the lighting you use every day. Older incandescent, halogen and fluorescent technologies generally use more electricity than modern LED alternatives, particularly in homes where lights operate for several hours each evening.

Energy efficient LED lighting uses less power to produce useful illumination and can offer a longer operating life than many older lighting technologies. For homeowners, that can mean fewer replacements and more flexibility when updating the way different rooms are lit.

Energy-efficient LED lighting solutions for residential spaces

ELWA’s LED lighting range includes:

  • LED downlights
  • LED battens
  • LED tubes
  • panels
  • tracklights
  • wall washers
  • floodlights
  • other general and project lighting options

Lighting performance involves more than wattage. Colour temperature affects whether a room feels warmer, cooler or more neutral, while beam angle, brightness and fitting position influence how evenly the space is illuminated. A living room may call for a softer atmosphere, while a kitchen or study generally benefits from clearer task lighting.

Products such as our LED tubes can provide an efficient option when replacing suitable older fluorescent lighting.

The actual savings from energy saving solutions for homes will vary according to the number of fittings, existing lighting technology, operating hours and products selected. We therefore recommend considering both performance and suitability rather than relying on a single savings figure.

Residential Architectural & Decorative LED Lighting

Residential lighting solutions should support the way you use a space while also complementing its appearance. In a renovation, new build or apartment project, the right fitting can contribute to the overall design rather than simply providing light.

Architectural and decorative LED options can be considered for:

Living areas

where layered lighting can create a comfortable atmosphere

Kitchens

where practical task lighting can be combined with decorative features

Bedrooms

where softer lighting can support a relaxed setting

Hallways

stairs and circulation areas requiring clear illumination

Apartments

where space-conscious fittings and coordinated designs can work well

Outdoor areas

including entrances, pathways and entertaining spaces

Feature areas

where directional lighting or wall washers can highlight finishes or architectural details

Decorative spaces

where the design of the fitting contributes to the room itself

Our architectural lighting collection brings together contemporary LED technology, general lighting and decorative designs. ELWA’s project lighting range includes options for apartments and other environments where appearance, efficiency and practical performance all need to be considered together.

Residential LED lighting solutions can also be planned across several rooms at once, helping create a more consistent lighting style throughout a home or development.

Find the Right Energy-Efficient Solution for Your Home

Every property has different water-heating demands, electrical infrastructure, room layouts and lighting preferences. Taking time to understand these requirements before selecting products can reduce the risk of choosing equipment that is too large, too small or simply unsuitable for the application.

Energy-efficient hot water and lighting options for residential properties

A practical selection process can include:

  1. Understand the home’s requirements. Consider who uses the property and how hot water demand changes throughout the day.
  2. Identify the hot water outlets. Note whether the system will serve a basin, kitchen sink, shower or several outlets.
  3. Consider temperature and flow. The amount of hot water required affects the model and power level needed.
  4. Review available electrical capacity. An appropriately licensed professional can confirm what the property can support.
  5. Compare energy efficient hot water systems. Select equipment according to the actual application rather than capacity alone.
  6. Identify lighting requirements. Think about room use, brightness, colour temperature and the overall style you want.
  7. Select suitable LED products. Match the fitting and performance to each part of the home.
  8. Ask ELWA for guidance. Our team can help you narrow down the options when you are unsure which product suits the project.

Energy-Efficient Solutions for New Homes, Renovations & Apartments

Decisions made during a new build or major renovation can affect household energy use for years. ELWA works with homeowners, builders, renovators, landlords and project teams looking for energy efficient home solutions that can be considered early in the planning process.

Our products can be considered for:

  • new homes specifying efficient water heating from the outset
  • renovations replacing ageing hot water equipment
