WATER HEATING THERMAL STORAGE
To increase the transfer of heat, this type
of store can utilise an external high efficiency plate heat exchanger (that will require an additional circulation pump). Separating the potable water from the
storage medium provides opportunities to use lower pressure vented thermal stores that will not fall under the auspices of the Pressure Systems Safety Regulations. The flow through the primary coils –

and so the charging of the store – can be successfully controlled by an integrated multivalent controller that will optimise the flows from heat sources, attempting to make maximum use of the lowest cost (and lowest carbon) source. In many cases the most beneficial heat source is likely to be solar thermal collectors. So, for example, in such an application
the temperature is compared in the solar collectors to that in the base of the thermal
