Renewable Energy - Solar Thermal

Solar Thermal water heating systems use solar collectors fitted to your roof to collect heat from the sun and use it to warm water which is stored in a hot water cylinder.

There are two types of solar water heating panels, evacuated tubes and flat plate collectors and a whole range of fixing methods to suit your property.

Solar Hot water systems can help cut your fuel bills, reduce your homes carbon emissions and DHR are excellently placed to help you design and install the ideal systems to suit your requirements.

A solar hot water system can be fitted in most homes within 3 days and products carry full manufacturer’s warranties.

Ongoing research shows that a solar hot water system for an average 3 bedroom semi-detached property should provide over 30 years of trouble free use with minimal maintenance.

Using a sustainable fuel source hot water is provided without depleting the fossil fuel reserve or generating carbon dioxide or other harmful emissions.  There are no on-going fuel costs for a solar hot water system, unlike a standard boiler, and it will provide a substantial environmental impact.

How does it work?

Solar Thermal Hot Water or Solar water heating systems use free heat from the sun to warm domestic hot water. A conventional boiler or immersion heater is then used to top up and make the water hotter if required, or to provide hot water when solar energy is unavailable.

For domestic hot water there are three main components: solar panels, a heat transfer system, and a hot water cylinder. Solar panels - or collectors - are fitted to your roof. They collect heat from the sun's radiation. The heat transfer system uses the collected heat to heat water. A hot water cylinder stores the hot water that is heated during the day and supplies it for use later.
Solar collectors can be mounted on top or inset into the existing roof covering to lower the profile.

Solar water heating can be used in the home or for larger applications, such as swimming pools.

Is my property suitable?

Preferably you will need 3-4m2 of southeast to southwest facing roof receiving direct sunlight for the main part of the day.

Cost and maintenance

The typical installation cost for a domestic system is £3,000 - £5,000.
Solar hot water systems generally come with a 10-year warranty and require very little maintenance. A yearly check by the householder and a more detailed check by a professional installer every 3-5 years should be sufficient.

30 years life expectancy

20 years anti-corrosion guarantee

10 year panel performance guarantee

2 year guarantee on parts

Carbon monoxide saving of approximately 1 tonne per year
(Based on an average domestic system)
