Solar Thermal Store Cylinders
A new range of Solar Thermal Store cylinders aimed at those who wish to combine solid fuel heat storage with solar energy.
Available both in cylinder and combination style, the Solar Thermal Store unit provides hot water via a thermal mixing valve at high pressure supplied direct from the mains water supply. Requiring only access to a cold water mains supply and a facility to overflow to the outside (direct from the combination units and from a header tank for cylinder units), the Solar Thermal Store can be located almost anywhere within the dwelling or business premises. Simple to install with no requirement for an unvented certificate and being able to take various heating inputs the Solar Thermal Store offers far greater flexibility than the vented or unvented units.
Below you can see an example of our Solar Thermal Store, which is so-called because it can use various heat inputs to heat the stored water. In addition to having the components required for solar heating, the Solar Thermal Store has a number of direct tappings (O and P on the diagram below) which can be used for heating the stored water by various other means, such as, woodburners, pellet/ biomass boilers, range cookers, or other gravity circulating applications. These direct tappings can also be used to take heat from the stored water for the purpose of heating the premises via open vented radiator circuits, heat dump or under floor heating circuits. The same can be done indirectly by fitting the Solar Thermal Store with a high efficiency coil, allowing the radiators and/ or underfloor heating circuits to be installed as sealed systems. However if the customer requires a bespoke Solar Thermal Store to be manufactured to their specification with extra connection ports or ports omitted, we can offer such a unit.

The Solar Thermal Store is also available as a combination type.
Approximately 50mm ODP foam insulation is applied as a standard, giving heat loss performance well above that required by Part L of the building regulations, but this can be increased if required, up to and including 75mm. Where aesthetics are important we also manufacture a cased unit. Examples of both finishes and sizes are shown on this page.
The most common sizes that we manufacture are listed below with their respective capacities. However, such is the flexibility of copper we can offer bespoke heights and diameters where space or water volumes are critical.

All Solar Thermal Store units are supplied with the following necessary components needed for correct operation:
- Thermal Mixing valve
- Expansion vessel
- Pressure reducing valve
- Non return valve
- Immersion heaters (where applicable)
- Ancillary pipework for mixing valve arrangement
- Ball valve and byelaw kit (combi only)

|---|---|
| Letter on Diagram | Connection type |
| A | Hot water draw off plus Thermostatic Mixer valve |
| B | Cold mains water in |
| C | Expansion vessel |
| D | Vent |
| E | Cold feed |
| F | Solar Connections |
| G | Immersion Port |
| H | 2nd Immersion Port (optional) |

| J | Solar stat pockets |
| K | Dial Gauge |
| L | Dump Port |
| M | Aqua Control Stat |
| N | Boiler connections |
| O | Alternative Direct Flow connections * |
| P | Alternative Direct Return connections * |
* O and P are direct flow and return connections which can be used, either as an alternative to the boiler coil (N), or as extra heat inputs from appliances such as solid fuel burners, pellet/ biomass boilers, or range cookers. They could also be used for extracting heat from the multistore to supply radiator or under floor heating circuits.
Such is the flexibilty of copper we can offer bespoke heights and diameters where space or water volumes are critical or replicate various old thermalstore units. Please Contact Us to discuss your requirements.
