Heat as a Service (HaaS) using Warmstone Zero Carbon Boiler (ZCB)

Caldera开发了一种零碳锅炉(ZCB)，它从电网中获取可再生电力，并将其转换为热量，储存在机组中，直到用户想要取暖或热水。ZCB的内部有一个创新的核心，商标是“瓦姆斯通”技术。瓦姆斯通技术是一种低成本的存储介质，能够吸收可再生电力，并存储相当于一个四卧室家庭的能量，在最冷的冬天覆盖24小时，或者在夏天存储7天的热水。通过有效的绝缘策略，每天损失5%-10%的能量得以保留。这些热损失比传统的蓄热方法(如夜间蓄热式加热器)低5倍以上。这个项目旨在通过以下方式释放ZCB的全部潜力：1.开发通信，使能源供应公司可以每分钟设置和改变充电时间和费率；2.从热接口单元(取代传统锅炉)收集热使用数据，以便只对房主使用的热量收费，而不是向ZCB3供电。与大型社会住房房东合作建立初步试验点，这将导致2021年安装5+，并可用于证明快速大规模部署是可能的。供给侧公司目前正在开发软件，以积极控制家庭需求，并通过改变消费者行为来更智能地使用能源。火山口瓦姆斯通方法提供了一种储存电力供暖的方法。采暖是家庭最大的能源需求--通常是房主其余用电量的4倍。HAAS模型将帮助低收入个人和家庭，他们将从降低能源成本中受益最大，因为它展示了ZCB可以在长期融资模式下供应和安装。HAAS模型已经在许多有热泵或传统锅炉的国家进行了试验，但ZCB不能根据一年中的不同时间将充电和供热分离1至7天。这意味着，当可再生能源发电且电价最低时，该机组可以充电。热泵是实时工作的，虽然它们会产生“额外的免费热量”，但它们也必须在消费者需要热量或热水时运行，而不是在可再生能源发电时运行。拥有成本较低的低碳或零碳供暖系统通常前期资本成本较高，这使得最需要节省资金的人无法使用它们。为了消除这一初始资本支出，该设备可以由第三方提供资金，用户的成本将在预期的20年寿命内分摊。

Caldera has developed a Zero Carbon Boiler (ZCB) which takes renewable electricity from the grid and converts it into heat which is stored within the unit until the consumer wants heating or hot water. The ZCB has an innovative core inside that is trademarked as "Warmstone" Technology. The Warmstone technology is a low cost storage media that is able to absorb renewable electricity and store the equivalent energy for a four bedroom home to cover a 24 hour period on the coldest winter day or seven days of hot water in the summer. The energy is retained with 5-10% losses per day with an efficient insulation strategy. These thermal losses are over 5x lower than conventional methods of storing heat, such as night storage heaters.This project is about unlocking the full potential of the ZCB for Heat as a Service (HaaS) by:1. Developing the communications so that the timing and rate of electrical charging can be set and varied on a minute by minute basis by an energy supply company,2. Collecting heat usage data from the Heat Interface Unit (which replaces the conventional boiler), so that the homeowner can be charged just for the heat that they use rather than the electricity supplied to the ZCB3. Working with large social housing landlords to establish initial trial sites, which will lead to 5+ installations in 2021 and can be used to demonstrate that rapid wide scale deployment is possible.Supply side companies are currently developing software to actively control demand in the home and smarter ways to use energy by changing consumer behaviour. The Caldera Warmstone approach provides a means for storing electricity for heating. Heating is the largest home energy demand - normally 4x the rest of the homeowner's electricity usage.The HaaS model will help low income individuals and families who will benefit the most from reduced energy costs by showing that a ZCB can be supplied and installed under a long term finance model.The HaaS model has been trialed in a number of countries with heat pumps or conventional boilers, but not with a ZCB that is able to decouple electrical charging and heat supply by 1 to 7 days depending upon the time of year. This means that the unit can be charged when renewables are generating and the electricity price is lowest. Heat pumps work in real time and although they generate "additional free heat" they also have to operate when the consumer wants the heat or hot water, not when renewables are generating.Low or zero carbon heating systems with lower cost of ownership normally have high upfront capital costs that make them inaccessible to those that have the most need for savings. To eliminate this initial capital outlay, the unit can be financed by a third party and the cost to the user spread over the expected 20 year life.
