We supply & install solar thermal systems to suit requirements

Whether you are replacing an old range cooker or an external oil boiler, there is an appropriate renewable heating system to suit every circumstance.

Installing a solar water heating system reduces costs, is exceptionally energy efficient and could even generate income for your household through the government’s Renewable Heat Incentive. Evacuated solar thermal tubes collect huge amounts of solar energy throughout the day and could provide up to 60% of your yearly hot water requirements.

Evacuated solar tubes consist of a set of parallel cylindrical tubes that can be fully connected to your building’s existing boiler. Alternatively we can use the flat plate technology, a neater looking system which may suit your house.

Included in the specification are evacuated tube solar energy collectors; hot water storage tanks made of high grade stainless steel, expansion vessels, circulating pumps, gauges and sensors. This powerful, market-leading solar thermal system can be relied upon to provide enough hot water for all domestic and heating needs, and can even be used to effectively and sustainably heat swimming pools.

Solar Thermal system and Biomass pellet boiler for two properties in coastal setting on Gower


Property Type and Location

These two properties at the very successful Hill End Campsite are a typical Welsh stone cottage and a stone barn conversion. Set on the stunning Gower they have a wonderful and very exposed aspect by the sea.

Pre-existing System

Hill End Farmhouse and camping is set on the stunning Gower Peninsula and consists of a typical Welsh stone cottage and a stone barn conversion. The owners are very eco-friendly, and had already solar panels and a wood pellet boiler installed to provide heat and hot water to the two houses. However, the existing wood pellet boiler was outdated and less efficient than more modern models.

The solar panels had ceased to function and needed replacing. The clients were pleased to learn that newer systems would not only further reduce their carbon foot print, but also be more efficient. On top of this, both qualify for the governmental RHI (Renewable Heat Incentive) scheme – the previous system hadn’t qualified.

New Solution

Solar Thermal
As mentioned earlier, the existing solar panel system was of an old type that lent itself to overheating. Newer products have come on to the market which are more efficient and sophisticated. And, many qualify for the RHI scheme.

From a selection of options the clients decided on Navitron evacuated solar thermal tubes. Whilst these are not as neat looking as the alternate flat panels they are exceptionally energy efficient, collecting huge amounts of solar energy throughout the day and providing up to 60% of your yearly hot water requirements. They also reduce costs.

We had also previously installed the compact Domusa system at this property.

The funding
Because the one boiler serves two properties, it qualified for the Non-Domestic RHI. The Non-Domestic RHI is extremely advantageous but it is not easy to access. In case of the Hill End farm the process actually required a detailed Heat Loss Assessment and evidence relating to the pre-existing Underground Heat Main (UGHM).
Therefore we managed the application process on behalf of the client and secured the full RHI for the heating system. The clients will now receive 20 years of RHI payments and pay back their expenses in around 3 – 4 years, an excellent return on their investment.

New Renewable Heating System Benefits

  • This system versus oil has significantly reduced C02
  • They receive 20 years RHI payments
  • This system was compatible with the existing boiler
  • RHI payments for a period of 20 years
  • Increased efficiency
  • Sophisticated controls and ease of use.

The problem – outdated technologies

The solar panels on the building were not efficient enough nor did they qualify for RHI payments.

Considerations

Limitations in space and compatibility with existing wood pellet system were two key factors.

The solution

Navitron evacuated solar thermal tubes are exceptionally efficient and also function well with the Domusa system.

Benefits – rapid return on investment through the RHI and a cleaner, easier, sustainable heating system

  • This system was compatible with the existing boiler
  • RHI payments for a period of 20 years
  • Increased efficiency
  • Sophisticated controls and ease of use.
