Overview
Warmstone for Homes
Warmstone is the boiler replacement that makes it easy to cut your carbon. It delivers plenty of hot water, on demand and at the same temperature as the boiler it replaces, meaning no radiator upgrades or other disruptive building work is required.
Warmstone is a heat battery – it contains a core that heats up using electric elements similar to those found in a kettle. Vacuum insulation means this heat can be stored for up to 23 days.
As well as working in homes, Warmstone can also be used in other buildings such as offices and churches, where several Warmstone units can work together to provide as much thermal storage as is needed.
Cuts Carbon
Uses renewable electricity
Weatherproof
Installed outside or in garage
Made in Britain
Built in our Hampshire factory
Heat & Hot Water
Same water volume and temperature as a boiler
Minimal Disruption
No new radiators or insulation
Recyclable
Non-toxic materials, recyclable at end of life
Compatible with most radiators
The Warmstone works with your current pipes, radiators or underfloor heating. As it produces water at the same temperature as your boiler there will be no change in comfort.
Compatible with most controls
You can keep your existing thermostats and other heating controls. The Warmstone will work with traditional controls, or most smart thermostats.
Store your solar power
Warmstone is a great complement to solar panels (PV). Storing energy as heat means lower costs and capacities 7-10 times greater than that of a typical chemical battery. Advanced electronics mean every watt of spare solar can be used.
Many homes will have enough solar to provide free hot water throughout the summer, and Warmstone’s ultra insulation means it can smooth out dips in the weather. As a result you can enjoy a hot bath a week or more after a sunny day.
Switch from heating oil
Heating oil is expensive, inconvenient and high in carbon. We hear from many customers using heating oil, and also LPG, that they have had a quote to install a heat pump but the cost and disruption of the new heating system, insulation and radiators means it is not viable.
For these homes Warmstone is a great alternative. It can be fitted outside, and connected to the existing heating system to replace or complement a boiler. Water temperatures remain the same, so no other changes are needed.
How It Works
Core Heated
Electricity is used to heat the Warmstone’s core. Temperatures inside range from 200C to 500C.
Heat Stored
When the heating is turned on water circulates through the Warmstone and into the radiators and hot water cylinder.
Heat Used
When the heating is turned on water circulates through the Warmstone and into the radiators and hot water cylinder.
Requirement:
Suitable Space
The Warmstone is large, so it is ideal for detached and semi-detached homes and is usually fitted in a garage or garden. It is fully weatherproof, and ultra insulation means cold has little impact on performance.
Requirement:
Hot Water Cylinder
The Warmstone is currently designed to work with a hot water cylinder. A combi boiler replacement that does not require one is planned in the coming years.
Included with every Warmstone are sensors and controls provided by myenergi, a like-minded manufacturer and the makers of zappi, the best selling UK-made electric vehicle charger. The Warmstone is designed to charge as quickly as possible using all the electricity available. Intelligent controls constantly monitor how much power is being used, so if you put on the kettle while the Warmstone is charging it will turn down in a matter of milliseconds.
If you have other devices from myenergi, such as the zappi or eddi, they will be shown alongside the Warmstone in the app. This is available free from the Apple Store or Google Play.
