Experience the Power of an Electric Boiler with Climastar

Join the green revolution and switch to an environmentally friendly, highly efficient electric boiler by Climastar. Our range of electric boilers provides you with a cost-effective, eco-conscious alternative to traditional gas or oil boilers.

What is an Electric Boiler?

An electric boiler is a device that uses electricity instead of gas or oil to heat your home. It heats water that is then circulated through radiators or used for hot water in your home. Unlike conventional boilers, electric boilers don’t emit harmful gases, making them an eco-friendly choice. With Climastar electric boilers, you can embrace the convenience of modern heating while contributing positively to the environment.

Our Electric Boilers

At Climastar, we proudly present two top-tier electric boilers: the Thera Combi and the Stromboli System Boiler, each designed to accommodate different property sizes while ensuring optimal heating efficiency.

Our Thera Combi boiler is a comprehensive solution that stands out in its class. It excels by delivering hot water for radiators and supplying up to 10 litres of water per minute for baths and showers. Specifically designed for properties with up to two bedrooms, this compact yet robust unit can easily fit in a utility room or an airing cupboard. Its state-of-the-art circuit board and wireless installation add to its convenience, while its impressive 99% efficiency ensures you’ll be warm without being wasteful.

For homeowners with larger properties accommodating up to four bedrooms, the Stromboli System Boiler is your perfect match. This boiler boasts a versatile design that allows it to work harmoniously with an existing hot water cylinder or in tandem with Climastar’s proprietary range of electric water heaters. With external temperature control, you can adjust your heating requirements to the exact degree, ensuring your comfort is always met without compromise.

Both our Thera Combi and Stromboli boilers showcase innovative design aspects to ensure quiet operation and maximum efficiency. They embody Climastar’s commitment to green, sustainable heating solutions that don’t compromise on power or reliability.

Why Install an Electric Boiler

Electric boilers are the future of home heating. They’re energy-efficient, eco-friendly, and operate quietly compared to traditional boilers. They’re also versatile, with models like the Climastar electric combi boilers capable of heating both small and large properties. By opting for an electric boiler, you make a significant stride in reducing your carbon footprint and enhancing your home’s energy efficiency.


High Energy Efficiency

Electric boilers are designed to convert nearly all the electricity they consume into heat, resulting in minimal energy wastage. Their efficiency ensures that you get more value out of every unit of electricity used, reducing overall energy consumption and lowering your electricity bills.

No Fuel Costs

Unlike traditional boilers that rely on expensive fossil fuels like gas or oil, electric boilers solely use electricity for operation. This eliminates the need to purchase, store, or refill costly fuel, saving you money on fuel expenses and reducing the impact of fluctuating fuel prices.

Reduced Maintenance Costs

Electric boilers have simpler designs with fewer moving parts compared to gas or oil boilers. As a result, they often require less frequent maintenance and are less prone to mechanical issues. The reduced need for professional servicing and parts replacement translates to lower maintenance costs over the boiler’s lifespan.

Long Lifespan

Electric boilers have longer lifespans compared to traditional boilers. With fewer components subject to wear and tear, they tend to endure for many years with proper maintenance. This extended lifespan saves you money by delaying the need for a boiler replacement, which can be a significant investment.

No Flue or Chimney Maintenance

Electric boilers do not produce any combustion gases, eliminating the need for a flue or chimney to exhaust fumes. As a result, you are not required to invest in regular inspections and cleaning services for these components, leading to further cost savings.

Why Choose A Climastar Electric Boiler

The Climastar electric boiler range is meticulously engineered to the highest standards, positioning our products at the forefront of the heating industry. Our combi electric boilers have gained a well-deserved reputation for excellence, becoming a preferred choice for households seeking a modern, eco-friendly alternative to traditional fossil fuel-based heating systems.

Quiet operation is a defining feature of Climastar boilers, ensuring your home stays peaceful while enjoying the comforting warmth. We’ve also ensured that our boilers deliver generous heat to radiators, creating a comfortable environment in your home, regardless of the outdoor weather.

What truly sets Climastar boilers apart is their minimal maintenance requirements. We believe in creating hassle-free experiences for our customers, so we’ve built boilers that require little to no upkeep, all while delivering 99% heating efficiency.

Additionally, our electric boilers are compatible with solar power. This capability opens the door to even more opportunities for saving on energy costs and further reducing your carbon footprint, embodying our commitment to sustainable living.

Each Climastar electric boiler comes equipped with an external temperature control, providing you with the flexibility to adjust your heating to your exact preferences. Furthermore, we’ve incorporated safety features like a low water pressure warning and a resettable thermal safety cut-out, ensuring your boiler operates safely at all times.

How Do Our Electric Boilers work

Climastar’s electric boilers utilise the power of electricity to generate heat in a remarkably efficient and effective manner. Electricity heats up water within the boiler, which is subsequently distributed to your home’s radiators or used for hot water needs in baths, showers, and various appliances. This heat transfer process is a testament to the simplicity and efficiency inherent in electric boilers.

Our boilers come packed with a variety of essential components that contribute to their superior performance. These include a pump, an expansion vessel, an automatic air vent, and a pressure gauge. All these parts are seamlessly integrated within the boiler, ensuring its effective operation while keeping maintenance needs to a minimum.

The efficiency of our boilers is truly unparalleled, with the potential to reach an impressive 99.8%. This remarkable efficiency is facilitated by the state-of-the-art circuit board that regulates the boiler’s operations, ensuring it runs smoothly and efficiently at all times. For added user comfort, external temperature control allows you to tailor your home’s heating to your precise needs.

For larger homes, our Stromboli System Boiler offers flexibility, as it can work with existing hot water cylinders or be integrated with other Climastar heating systems. Conversely, for smaller properties, our Thera Combi boiler provides a compact solution that can be easily accommodated in a utility room or an airing cupboard. Choosing Climastar means you have the power of choice and the assurance of exceptional performance.
