Electric boilers are an efficient alternative to traditional gas boilers, especially for homes without mains gas or those looking to reduce their carbon footprint. These boilers heat water with electricity and have an efficiency rating of 99-100%, compared to the typical 92-93% of gas boilers. Let's look at the different types of electric boilers and how they can be used for different purposes, such as electric boiler hire for emergencies.

How Do Electric Boilers Work?

Electric boilers heat water by drawing energy from the mains power supply. The heating element heats the water, which is then used in central heating or hot water taps. Their operation is simple, but the specific mechanism varies depending on the type of electric boiler chosen.

Types of Electric Boilers

 

1. Electric Combi Boilers

  • Description: These combine central heating and water heating in one compact unit, ideal for smaller homes.
  • Advantage: On-demand water heating minimizes waste and energy use.
  • Limitation: May take a few seconds to warm up water.
2. Electric System Boilers
  • Description: Equipped with a water storage tank for consistent hot water supply.
  • Advantage: Best for larger homes with high water demands.
3. Dry Core Storage Boilers
  • Description: Utilize off-peak electricity, storing heat in materials like bricks.
  • Advantage: Cost-effective for those with time-of-use tariffs.
4. Heat-Only Boilers
  • Description: Traditional boilers using cold water tanks and cylinders.
  • Advantage: Suited for large properties with significant water requirements.
What Size Electric Boiler Do You Need?

The appropriate size is determined by the property's size, number of occupants, and heating requirements. Boiler sizes are measured in kilowatts (kW), which indicates how many radiators they can support. For example, a 9 kW boiler is appropriate for households with six radiators. Other factors, such as insulation and ceiling height, influence the decision.

Emergency Solutions: Electric Boiler Hire and Rental

In the event of a breakdown, electric boiler hire or emergency boiler services can save lives. These services offer temporary heating solutions while repairs or replacements are scheduled. Whether for domestic or industrial needs, electric boiler rental ensures continuity of heating and hot water with minimal downtime.

Efficiency and Cost of Electric Boilers

Despite their great efficiency, electric boilers can be more expensive to run than gas boilers because of rising electricity costs. For example, the annual energy consumption of an electric boiler in a typical three-bedroom home may be around 12,366 kWh.

Summary

Electric boilers are a sensible alternative since they provide an efficient and eco friendly heating solution. Knowing the types and features of electric boilers will help you make an informed choice, whether you're thinking about installing one or looking into renting one for an emergency boiler situation.
