Thermal store - the safe way to
produce mains pressure hot water
Mains pressure hot water is a
luxury worth considering. Hot water at the same pressure as the
cold water yields a number of advantages: balanced supplies of
hot & cold water, no need for shower booster pumps, quicker fill
time with a bath, the list goes on.
There are however different ways
to achieve mains pressure hot water. You can either go the
'unvented' route (a route you should fully understand before
selecting) or the 'Thermal Store' route that is inherently
Thermal stores offer other
advantages besides safety.
They can accept several heat
sources simultaneously. These heat sources can even be those
deemed uncontrollable and therefore unsafe to feed into an
The open vented nature of a
thermal store allows it to accept heat from devices such as a
wood burning stoves or an AGA without fear of explosion from
over-temperature and/or pressure.
Thermal stores can even be
incorporated into the grand scheme of your household central
heating system. With all heat sources feeding into the thermal
store it is possible to run your heating circuit directly from
the cylinder - supplying preheated water straight to radiators,
improving response time dramatically.
Consider, a central heat store
into which to feed any and all heat sources and in return you
get mains pressure hot water and the chance for your wood burner
or AGA to centrally heat your home. Thermal stores can even be
heated by solar energy.
Having none of the risks
associated with unvented cylinders and all these advantages,
thermal stores are rapidly becoming the cylinder or choice. You
