No Discharge Pipes
Unlike other water storage systems, the HEATBANK® Pandora thermal store does not need a discharge pipe to the outside. As central heating is pumped directly from the stored water, sharing the same water, there is no need for any discharge pipes. Other forms of district interface systems typically require a discharge from the central heating system, as well as one from the hot water store resulting in two discharges
Smaller Primary Supply Pipework
District interface systems that do not utilise stored water require high flow rates to be delivered from the central boiler plant in order to drive maximum simultaneous hot water loading. To drive 30 litres of hot water to taps will require similar or greater flow rates to be supplied from the boiler plant, and if there are a number of flats drawing water at the same time the load on the boiler plant can be very large. The HEATBANK® Pandora thermal store uses stored heat to drive heavy water loads, and as such will typically only need 5 to 10 litres per minute to be supplied from the boiler. Load on the boiler is spread over time, reducing the peak instantaneous loading substantially.
Control over Volumes of Water Heated
Unlike any other storage system, the HEATBANK® Pandora thermal store allows the tenant to heat up only small quantities of hot water, if that is all that is required, or to heat up a full cylinder of water in preparation for periods of hefty water demand. The system can even be set-up to automatically vary the quantities of hot water stored to match the demands of the tenant. In addition, hot water can be obtained within minutes of a cold start, again unlike any other storage system.
District interface systems that do not utilise stored water require the boiler supply pipes to be kept hot in order to avoid long delays in supplying hot water once a tap is opened. In Summer, this results in constantly hot pipework and is a major cause of overheating cupboards and corridors, especially in well insulated modern developments. As the HEATBANK® Pandora thermal store uses stored heat within each property, hot water is always available instantly, while boiler pipework can be left to stand cold until a system calls to be reheated, and as this is usually timed it is quite common for primary pipework in corridors to stand cold for the majority of the time.
Not a Pressurised Unvented System
The stored water in the HEATBANK® Pandora thermal store is kept at atmospheric pressure with a vent to atmosphere, and as such is not bound by the safety regulations that apply to pressurised unvented systems.
No Limescale Build-Up In Store
It is the same water in the store in 10 years as the day it was installed, overcoming the problems of limescale build-up experienced with other types of storage system.
Fully Pre-Fabricated Systems
In order to make installation as simple as possible, the HEATBANK® Pandora thermal store can be supplied with all components and controls factory fitted, wired and tested, reducing installation to little more than connecting to pipework. The fitted control options extend to include full heat metering services, and even radio linked room thermostats, further simplifying installation on site.
