1. Scaffolding will be necessary up to the level of the guttering. This equipment will give you a safe working platform. Use additional roof ladders to prevent damage to the roof covering. Making measurements from the inside of the roof space/loft may be helpful.
When deciding where to locate the pump station, choose the shortest route for your pipework to the hot water tank.
2. The roof anchors get fixed into the underneath roof batons. You can remove a tile or slate to gain access. Measuring diagonally from corner to corner will help square up the anchors, ready for the aluminum mainframe to be fixed.
The best part of this installation is attaching the solar panels to the roof. Some styles of evacuated tube collectors allow you to piece together the array.
Please note - Ready-assembled collectors will need to be hoisted up to the scaffolding using a roofers pulley system. Some self-installers work alongside a roofing company for this stage of the installation.
An inlet and outlet hole for the pipes can be drilled through the tile/slate and resealed using roof-grade silicone. Make sure any exposed pipework is insulated by an 'Armoflex sheaf' up to the headers inlet and outlet ports.
3. Routing your pipework down towards the pump station can be done with professional 'ready insulated' pipe lengths containing the temperature sensor wire or traditional copper pipe. If the latter, then we recommend connecting with 'compression' joints. Connect the pump station to the correct hot and cold feed connections.
The Expansion Vessel gets installed next to the pump station so, allow for this area. Typical locations for these components are in the loft space, basement, or within the airing cupboard.
4. Some solar heating installations may require an upgraded hot water tank. Unvented or pressurised cylinders are typical, but a 'G3' plumbers accreditation is necessary - however, a traditional vented tank installed with a secondary solar coil is fine.
5. Now decide where to locate The Controller. If you're installing it in the bathroom, then a Part P qualification is required. Situated outside the bathroom area is more common.
Routing the Temperature Sensors from the controller to the tank and header can follow the route of the pipework in most cases.
6. Pressurising the system with the Glycol fluid can be done with a plumber's pump unit. Flushing the system out of all air bubbles is essential, and the pressure of three bars is standard. The final operation is to set up the Management Controller and test the temperature sensors are reporting accurate readings.
Check pipework and connections.
7. Enjoy a cup of tea. You've joined a growing army of people taking advantage of solar technology today.
