Clean, Energy-Efficient, Instant Hot Water

As Sunamp was designed specifically to heat water rather than home heating, we wouldn’t recommend it for this purpose.

No maintenance is needed, there are no signs of degredation for at least 50 years so no need to replace. Heated water is fresh and not stored in a tank which can harbour bacteria such a legionalla. Hot water tanks are much larger; a Sunamp capable of providing 300 litres of water will fit in a small cupboard where as the equivalent tank would be almost 7ft tall. These can easily work with solar panels and heat pumps.

You don’t waste any energy as you only heat water that you use, but the final cost depends on whatever rate you’re on. There are also several sizes (and killowattages) depending on the volume of hot water your home requires. The full specifications of each system are on the brochure. As this is fairly new technology, there isn’t currently enough independent evidence available to estimate typical savings. However, based on your individual home and circumstances, this can be estimated to help people come to the right decision for you.

It depends on what your rates are now, what system you’re currently using and which size Sunamp you have installed. They can give you an individual quote so you’d be able to work out potential money saved over time so you can make an informed decision.

The EU energy rating is A+. Also, if you have a renewables system, solar, etc an energy storage system like Sunamp can reduce your fuel bills and carbonby allowing you to make the most of free renewable energy by storing it until you need it.

If you take into account the charging time of the Thermino 210 e, should be in the region of 4 hours to 4.5 hours (from cold), including the heating element cycling at start up. In this time the heat loss would be 0.77 (heat loss over 24 hours)/ 24 *4.5 = 0.14kWh of heat loss during the time of charging. The energy used to get 10.5kWh into the heat battery would work out to be 10.5 + 0.14 = 10.64kWh. This without removing heat from the heat battery, during this period and stored in an internal ambient environment. Meaning that your efficiency calculation would be 10.5/ 10.64 = 98% efficient. For the in-depth efficiency calculation for our product against a standard, we use the standard EN 50440, the values from AEC are listed in the manual Technical Specification section.

No maintenance is needed for the duration of the battery lifetime. The battery should operate with no degredation for at least 50 years.

The battery should operate with no degredation for at least 50 years.

The Sunamp phase change battery consists of a patented and non-toxic phase change material formulation called Plentigrade P58. This is a food-grade product (although it’s not advised that you actually eat it) – sodium acetate trihydrate – its core ingredient, is actually a flavouring used in salt and vinegar crisps, so if you like crisps, you may have eaten it in small quantities! PCM can be safely recycled back into the ground if necessary and comes from renewable, non-carbon sources. These batteries have been tested to work with no degradation whatsoever for at least 50 years, so consumers don’t need to worry about replacing them. Mining Lithium, however, involves large quantities of water, production of large quantities of mineral waste, the alteration of the hydrological cycle etc. Recycling lithium is actually extremely complicated and also costs more than it does to mine for more lithium. For the few facilities that can recover materials from lithium-ion batteries, traditional processes aren’t efficient enough to recover high-grade lithium to be used in remaking batteries therefore they tend to only recover other elements used. It’s also not always properly recycled, on top of the fact that people don’t always correctly recycle them – just as many people don’t correctly recycle plastic. The involved metals like cobalt, nickel, and manganese (toxic and can contaminate water supplies and ecosystems if they leach out of landfills). So, they’re not relatively easy to recycle and if other more eco-friendly options can be used, they ideally should be.

The battery was created with the University of Edinburgh, and the UK’s national synchrotron particle accelerator, Diamond Light Source.
