Solar Hot Water Repair & Replacement Components UK
Solar PV Systems supplies solar hot water repair and replacement components for maintaining existing solar thermal systems. Our range includes solar hot water controllers, pump stations, heating fluid, compression fittings, flexible tube connections, sensor cables, pipework fittings and other solar thermal spare parts.
Whether you are replacing a worn fitting, maintaining an existing solar hot water system or sourcing a replacement component, our range provides individual parts for a variety of solar thermal applications throughout the UK.
We are a supply-only business and do not provide installation services. Check the product descriptions and technical specifications carefully before ordering to ensure that the selected component is suitable for your system.
Solar Hot Water Controllers & Pump Stations
Solar hot water controllers monitor system temperatures and manage circulation according to the system’s operating requirements. Pump stations contain circulation components used to move solar heating fluid around the solar circuit.
Browse our Solar Hot Water Controllers and Solar Hot Water Pump Stations for replacement and maintenance requirements. Check the specifications of the existing equipment before selecting a replacement.
Solar Heating Fluid
Solar thermal systems use heat-transfer fluid to carry heat from the solar collectors to the hot water cylinder. The fluid must be appropriate for the system and its operating conditions.
We supply ready-mixed solar heating fluid for relevant solar thermal maintenance and replacement requirements. Check the product information and your system manufacturer’s guidance before ordering.
Solar Compression Fittings & Connectors
Solar thermal pipework uses a range of fittings to connect pipes, flexible tubes and other system components. Our range includes:
- DZR compression couplings
- DZR compression elbows
- Solar compression tees
- Solar male iron compression fittings
- Solar female iron compression fittings
- Male copper solar connectors
- Solar compression reducing olives and reducing bushes.
- Solar heating sockets, reducing sockets and other connection components.
Browse our Solar Compression Fittings category for additional options.
When choosing a fitting, check the connection type, dimensions and compatibility with the existing pipework and system components. Similar-looking fittings may have different connection requirements.
Solar Tube Fittings & Flexible Pipework
We supply fittings and accessories for solar thermal flexible tube connections, including DN12 and DN16 solar connectors.
The range also includes flexible tube connections, tube brackets, C-clip nuts, pipework C-clips and fibre washers. These components may be required when maintaining existing pipework or replacing worn or damaged connection parts.
Check the dimensions and connection specifications of the existing components before ordering. You can also browse the Solar Heating Components category for related products.
Solar Sensor Cables
Sensor cables connect temperature sensors to the relevant control equipment in compatible solar thermal systems.
We supply grey solar sensor cable and other sensor cable options. Check the cable requirements and compatibility with the controller and sensors used in your existing installation before ordering.
Solar Pressure Relief Valves & Safety Components
Pressure relief valves and other suitable safety components form part of the protection arrangements in solar thermal systems.
Our range includes a solar pressure relief valve and associated system components. When replacing a valve or other safety-related part, confirm the required specification against the existing system and the manufacturer’s instructions.
Solar thermal equipment can operate at high temperatures and pressures. Maintenance and replacement work should be carried out by a suitably competent person.
Solar Roof Entry & Pipework Accessories
Our solar heating components also include roof-entry and pipework accessories used in relevant solar thermal installations.
Products include solar roof-entry slate components, reducing bushes, washers, clips and other small fittings. Check the product details to confirm the intended application and compatibility before ordering.
Solar Hot Water Spare Parts
Our range includes individual components for customers maintaining existing solar thermal installations. Depending on the requirements of your system, these may include:
- Solar heating controllers
- Pump stations
- Solar heating fluid
- Sensor cables
- Pressure relief valves
- Solar heating accessories
You can also consult our Solar PV Systems Hot Water Spares guide for further reference.
Choosing the Correct Solar Hot Water Spare Part
Before ordering a replacement component, identify the existing part and check:
- Component type: Confirm whether you need a fitting, connector, cable, valve, controller, pump station or fluid.
- Connection size: Check the pipe diameter, thread or compression connection as applicable.
- Component specifications: Compare the product details with the existing part.
- System compatibility: Check suitability for your solar thermal system and its operating conditions.
- Manufacturer information: Use the existing component identification and system documentation where available.
If you are unsure which component you need, contact us with the existing part details, measurements or model information so that we can help identify a suitable product.
Maintaining an Existing Solar Thermal System
Regular inspection and appropriate maintenance can help identify worn, damaged or unsuitable components. Replacement requirements vary depending on the system design, condition and manufacturer’s recommendations.
Common reasons for sourcing replacement parts include damaged pipework connections, worn fittings, faulty control equipment, pump station problems, fluid replacement and the need to replace a specified valve or accessory.
Always follow the system manufacturer’s guidance and use components suitable for the particular installation.
