Jaspi Ultrastore 500 has been designed from start to offer best possible thermal efficiency with a narrow footprint and to comply with the latest energy efficiency standards.

Square and low design allows this thermal store to be placed inside most of the properties without a need for a separate boiler room and it fits through a normal door.
Then we added a generous amount of coils and couplings for multiple energy sources.
To finish off, the tank was fitted with an internal baffle plate and all the couplings got the new "Leak Detect" sleeves.

The result is a truly modern thermal store with exceptional efficiency and flexibilty.


Accumulator efficiency is highly dependant on its insulation.
The type of the insulation, its coverage and very importantly how it 'binds' to the surface of the tank are the key points.
The insulation in Jaspi Ultrastore is high density closed cell Polyurethane which is heat fixed onto the surface of the tank in a giant mould.
This manufacturing technique allows the use of a higher density and better performing Polyurethane leaving no gaps for the heat to escape and the insulation will last for decades without losing its performance.


Ultrastore has gone through vigorous testing with all modern heat sources and their combinations which can be seen in the amount of couplings and their locations.
Ultrastore can be connected up to four separate energy sources, for example Heat Pumps, Solar Thermal, Solar PV and Wood Burners.
Naturally one of the heat sources can also be a traditional Oil or Gas burner which are often used as a back-up.

In addition, two separate heating circuits can also be connected, for example one for the radiators and another for the underfloor heating.


Indirect coils are used to supply domestic hot water from the thermal store. They can also be used to connect to the external heat sources like Solar thermal or smaller wood burners with a back boiler.

Ultrastore is fitted with three indirect coils as standard.
Two of these coils are 22mm copper with a power of 100kW each. They are often connected in series where the lower coil is a pre-heating coil and the top coil the main domestic hot water coil. By connecting them this way, the tank can provide much larger amount of hot water before cooling down. This two coil configurating also allows an easy connection for hot water circulation pumps.

The third and the lowest coil (18mm) is for Solar thermal loop or smaller wood burners.
Often it is necessary to connect the wood burner to the thermal store indirectly as the wood burner circuit needs to stay open vented whilst the main thermal store, including radiators, is pressurised. Ultrastore makes this type of installation easy, safe and affordable.


Ultrastore installation pack include all the blank plugs in brass or iron, air vent, drain plug and pressure relief valves for the accumulator & domestic hot water.
