About our solar water heating suppliers

RVR Solar

The RVR Solar range of products are our own brand products. Designed and manufactured specifically for RVR, the HP range of collectors offer excellent value as they have a very low cost per kWh of output. The collectors are also very easy to transport and handle as they are Heat Pipe type and the tubes can be disconnected from the manifold of the collector.

The RVR Solar range also feature very low cost 316 grade stainless steel cylinders.


Our Greek Solar Partner CALPAK was founded in 1976 as a member of British Petroleum (BP) group and with its well-trained engineers and technicians, became a pioneer in research, production and development of solar energy applications.

The 12VTN vacuum panel from Calpak has one of the highest gross efficiencies on the market in Ireland. They are designed to make the most of the roof space available and as they have a CPC Parabolic reflector, they have a very high aperture area relative to their overall dimensions. This means that a more compact installation is possible.


Located in Tyrol, Austria, TiSUN develops, produces and distributes high-grade solar systems that are able to resist the rough climate of the alpine mountains.

The FM-S flat panel from TiSun Is a modern, high efficiency flat panel collector. It is ideal for new build homes as it can be flashed in to the roof during building and offers a very attractive finish.


Individual solar water heating products

We sell all our solar water heating systems as individual products which either you or your plumber can buy. Please see the "Solar" section and "Water Heating Tanks" section of our product catalogue on the left hand menu of the site.

A better solution for most people is a pre-assembled solar kit. You can read more about these products below.

Preassembled solar water heating Kits

Preassembled kits are designed to reduce the complexity when choosing and purchasing solar heating equipment. These kits contain either the essential parts or all of the equipment required for a solar heating system. By pre-assembling the kits we can ensure quality and better value than when purchasing individual items.

Basic Kits Without Water Heater:
