Keep your existing cylinder with our retrofit DIY Solar Kit

Our newest deal and probably the best value on the net. This price includes VAT and delivery to your door.

Install solar panels, but keep your existing tank. A simple but effective way to upgrade to solar power without the complications of changing your cylinder.

How does the retrofit coil work?
The coils are designed to fit into your existing 2.5" immersion heater plug, converting your cylinder into a twin coil tank without the costly expense of extra plumbing. You connect the solar panel flow and return to the copper connections, and the solar panels will start to heat your domestic hot water.

Are they as effective as a twin coil tank?
Not quite. To maximise the output from a solar panel we still recommend the traditional route of a twin coil cylinder, however, the coils do work well and represent one of the cheapest methods of installing solar hot water into an existing house. If you decide to change your cylinder in the future, the solar panels can be retained.

What about my immersion heater?
Unless you have two immersion sockets this will have to go.

Can I fit these to both vented and unvented cylinders?
Yes, the coils are suitable for both standard (vented) tanks, and the high pressure unvented variant.
