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，并将其转化为热量，储存在机组内，直到消费者需要供暖或热水。ZCB内部有一个创新的核心，被注册为“Warmstone”技术。Warmstone技术是一种低成本存储介质，能够吸收可再生电力并存储相当于四居室住宅的能量，以覆盖最冷冬日的24小时或夏季7天的热水。通过有效的绝缘策略，每天损失5-10%的能量。这些热损失比传统的储热方法（如夜间储热加热器）低5倍以上。该项目旨在通过以下方式释放ZCB的全部潜力，即供热即服务（哈斯）：1.开发通信，以便充电的时间和速率可以由能源供应公司按分钟设置和改变，2.从热接口单元（取代传统的锅炉）收集热量使用数据，这样房主就可以只为他们使用的热量而不是供应给ZCB 3的电力收费。与大型社会住房业主合作建立初步试验场地，这将导致在2021年安装5个以上，并可用于证明快速大规模部署是可能的。供应方公司目前正在开发软件，以主动控制家庭需求，并通过改变消费者行为来更智能地使用能源。Caldera Warmstone方法提供了一种储存电力用于加热的方法。供暖是最大的家庭能源需求-通常是房主其余用电量的4倍。哈斯模式将帮助低收入个人和家庭，他们将从降低的能源成本中受益最多，因为它表明可以在长期融资模式下供应和安装ZCB。哈斯模式已在许多国家试用热泵或传统锅炉，但不具有能够根据一年中的时间将充电和供热解耦1至7天的ZCB。这意味着当可再生能源发电时，该装置可以充电，并且电价最低。热泵在真实的时间内工作，虽然它们产生“额外的自由热量”，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。拥有成本较低的低碳或零碳供暖系统通常具有较高的前期资本成本，这使得那些最需要储蓄的人无法使用。为了消除这种初始资本支出，该装置可以由第三方提供资金，用户的成本分摊到预期的20年寿命中。

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.
