Hot water cylinders vs Sunamp Thermino heat batteries

If you’re thinking about upgrading your water heating system, you’ve likely come across traditional hot water tanks and the revolutionary Sunamp Thermino heat batteries. While hot water cylinders have been the standard for decades, they’re quickly becoming overshadowed.

The traditional hot water cylinder: Time to move on?

Hot water cylinders have been a staple in UK homes for generations. They store large volumes of water, typically heated using gas or electricity. While they have served their purpose well, they come with a number of downsides:

• Large and space-consuming
  A typical hot water cylinder can take up a cupboard or loft space that could be put to better use.
• Heat losses
  Even a well-insulated tank will lose heat over time, leading to wasted energy.
• Slow recovery time
  Once the hot water runs out, you’ll have to wait for the tank to refill and reheat.
• Limited capacity
  If multiple people need hot water back-to-back, you may  find yourself running out.

Sunamp: The smarter alternative

The Sunamp Thermino is a modern heat battery that uses advanced phase-change material to store energy efficiently and deliver hot water on demand. Here’s why it’s a game changer:

• Compact, space-saving design
  Sunamp heat batteries are up to four times smaller than the equivalent sized hot water tank, freeing up valuable space in your home. Some models are compact enough to fit in a kitchen cupboard!
• Highly efficient
  With very low heat losses, the Sunamp retains energy much more effectively than traditional hot water cylinders. This is especially important when you pair your Sunamp with a solar PV system, as excess solar energy can be stored for use when the sun isn’t shining.
• Instant hot water
  No more waiting for a large tank of cold water to heat up. Sunamp heat batteries provide hot water on demand, and at mains pressure.
• Environmentally friendly
  Sunamp heat batteries can work seamlessly with grid electricity and solar PV, reducing your reliance on fossil fuels and helping to lower your carbon footprint.
• No mandatory annual maintenance
  Traditional hot water cylinders can suffer from limescale buildup and corrosion, leading to frequent maintenance. Sunamp heat batteries require no mandatory annual maintenance. There’s no risk of gas leaks, and as minimal water is stored, there’s no risk of legionella. Sunamp heat batteries also boast a market-leading 10-year warranty on the heating element: they are built to last, saving you money for years to come.

Other water heating methods: How do they compare?

Gas boilers

Gas boilers are very common in UK homes, but with rising energy prices and the push towards greener energy, they are becoming less appealing. They are also inefficient compared to electric solutions, and don’t pair well with solar PV systems.

Electric instantaneous water heaters

While these do offer hot water on demand, they are generally less efficient and struggle to meet the demands of larger households. They also lack the energy benefits of a Sunamp.

Heat pumps

Heat pumps can be efficient, but they require significant upfront investment and space for outdoor units. They aren’t always practical for smaller properties or retrofits.
