Electric Heating Vs Gas and Oil

Upgrade Your Home with the Future of Heating – RadTherm® electric radiators and Sunamp heat batteries for hot water.

Thinking about ditching your outdated gas or oil central heating system? You’re not alone. As concerns about the environment and energy efficiency grow, many homeowners are looking for cleaner and smarter ways to heat their homes. Here at Cotswold Heating Solutions, we introduce a revolutionary combination: RadTherm® German Electric Radiators paired with Sunamp Heat Batteries.

Why Move Away from Gas or Oil?

Environmental Impact:

Gas and oil boilers contribute significantly to greenhouse gas emissions. Switching to electric heating with renewable energy sources like solar panels minimizes your carbon footprint.

Safety Concerns:

Gas leaks pose a serious safety risk. Electric heating eliminates this concern, creating a safer environment for your family.

Maintenance Hassles:

Gas and oil boilers require regular servicing, which can be inconvenient and costly. Electric heating systems generally require no maintenance.

Efficiency:

Modern electric heating systems are highly efficient, converting 100% of the electricity they use into heat. In contrast, gas boilers lose some heat through flue gases and in some cases can be as little as around 65% efficient

The RadTherm® & Sunamp Difference

RadTherm Electric Radiators:

Precision Heating:

Unlike traditional radiators that heat the air unevenly, RadTherm® radiators provide radiant and convective warmth, ensuring a comfortable and consistent temperature throughout the room.

Smart Control:

Enjoy the convenience of precise thermostats and smartphone app control, allowing you to adjust temperature settings room-by-room for ultimate comfort and efficiency.

Sleek Design:

Enhance your home's aesthetics with a variety of stylish and modern radiator designs from RadTherm®. With dozens of different sizes and styles and with over 900 colours to choose from there is a radiator for every situation.

Instant Warmth:

No more waiting for stored heat to radiate. RadTherm® heaters provide instant warmth whenever you need it, perfect for chilly mornings or taking the edge off on a cold evening.

Unmatched Efficiency:

German engineering ensures these heaters convert electricity into heat with minimal energy loss, translating to lower energy bills compared to night storage heaters. Once at optimal temperature they typically consume around 15 minutes of energy per hour of use.

Sunamp Heat Batteries:

Smart Energy Storage:

Sunamp heat batteries can store heat generated during off-peak hours, reducing reliance on the grid during peak periods. This translates to lower energy bills.

Consistent Comfort:

Sunamp heat batteries provide cascades of main pressure hot water – enough for every household’s daily hot water requirements.

Precision Heating:

Sunamp heat batteries use a revolutionary phase change material (PCM) that absorbs heat when it's readily available and releases it when needed. Made from sodium acetate (salt and vinegar solution) it is food grade and no-toxic.

Here's a breakdown of how Sunamp works:

Heat Absorption:

Using energy from the grid, or from solar PV, heat is transferred to the Sunamp battery, where the PCM absorbs it and changes state from a solid to a liquid.

Heat Storage:

The stored heat can be held for extended periods with minimal thermal loss, thanks to the high-performance insulation surrounding the PCM.

Heat Delivery:

When hot water is needed, the Sunamp battery releases the stored heat, providing mains pressure hot water for your taps and showers.

Benefits of Using Sunamp Heat Batteries

Increased Efficiency & Lower Bills:

• Store excess heat when electricity rates are lower (can work with all electricity tariffs).
• Minimal thermal losses minimize energy consumption and lower electricity bills.

Improved Comfort & Consistent Hot Water:

• Sunamp ensures a continuous and comfortable hot water supply throughout the day and night, even during high demand periods.
• Eliminate the frustration of running out of hot water just when you need it most.

Environmentally Friendly:

• By reducing reliance on the grid during peak hours, Sunamp contributes to a lower carbon footprint and a cleaner environment.
• Can be paired with renewable energy sources like solar panels for a truly sustainable hot water solution.

Scalable & Versatile:

• Sunamp batteries are modular. You can customize the system capacity to perfectly match your hot water needs, whether you have a small apartment or a large family home.
• Integrates seamlessly with existing hot water heating systems, including gas, oil, or electric boilers.

Peace of Mind & Reliability:

• Sunamp batteries are built with high-quality materials and are designed for long-lasting performance and have an average life expectancy of 50 years +
• Requires no annual maintenance, saving you time and money.

Applications of Sunamp Heat Batteries:

Sunamp Heat Batteries are a perfect solution for a variety of applications, including:

Eco-conscious homeowners looking to reduce their environmental impact

Commercial buildings with high hot water demand

Residential homes of all sizes

Multi-unit dwellings and apartments
