What are the primary benefits of owning an emergency generator?

Investing in an emergency generator offers several key benefits for UK homeowners:

  1. Continuous power supply: Keep essential appliances running during outages, including refrigerators, heating systems, and medical equipment.

How do you choose the right size emergency generator for your home?

Selecting the appropriate generator size is crucial for meeting your power needs efficiently. To determine the right size:

  1. List essential appliances and their wattage requirements.

  2. Calculate the total wattage needed to run these devices simultaneously.

  3. Add 20% to this figure to account for startup surges.

  4. Choose a generator that exceeds this calculated wattage.

For example, if your essential appliances require 5000 watts, look for a generator rated at least 6000 watts. Consider future needs and potential additional appliances when making your selection.

What maintenance is required for emergency generators?

Regular maintenance is essential to ensure your emergency generator functions reliably when needed:

  1. Run the generator monthly for about 30 minutes to keep components lubricated.

  2. Check and change the oil according to the manufacturer’s schedule.

  3. Inspect and clean air filters regularly.

  4. Check and replace spark plugs as needed.

Proper maintenance not only extends the life of your generator but also ensures it will perform when you need it most.
