Solar Hot Water

Solar Thermal Systems

Safe & Protect Solar offer bespoke designed solar thermal hot water systems for any size of application from small domestic systems to large commercial scale projects. Our thermal systems are designed to match the individual requirements of the clients and are configured to achieve maximum possible efficiency.

A Safe & Protect solar thermal system can supply up to 70% of your annual hot water requirement for free.  In the summer it could be as much as 95%, and through the winter months the solar energy will ‘pre-heat’ the incoming cold water, resulting in a significantly reduced dependency on the primary hot water supply from the boiler system.  See below for more information about the potential savings.

Why Solar Thermal?

The Benefits

The Savings
How Does It Work?
The Costs

Depending on usage, a well-designed system from Safe & Protect Solar can reduce your energy bills substantially. Typically, a solar thermal system will provide:

80-90% of your hot water in the summer
40-50% of your hot water in the spring and autumn
10-15% of your hot water in the winter

It is also feasible that the system can also be designed to contribute towards heating your home substantially reducing heating bills over the course of the year.

The biggest savings will be made if your hot water is currently heated by electricity, followed by oil and then gas. However, the actual savings you’ll make on your bills will depend on how you use your hot water. To get a better idea of how much you could save, arrange your free survey today.

In closed-loop thermal systems, the fluid that circulates from the tubes to the water cylinder will never come into contact with the water that you get from your tap.

  • Cold water enters the hot water cylinder from the mains
  • Inside a closed loop, fluid is pumped up to a solar panel on the roof
  • Fluid passes through metal pipes inside the panel and is warmed by the sun
  • The fluid then passes into a coil inside your hot water cylinder, heating up the water
  • A second coil inside the cylinder is connected to your boiler, and brings the water up to the temperature set on your thermostat
The cost of your install will depend on a number factors such as the number of panels, the complexity of the plumbing required and the suitability of your current hot water system set up. Grants towards the cost of your system will soon be available through the Government’s Renewable Heat Incentive scheme.
The Renewable Heat Incentive (RHI)

About The RHI

The Renewable Heat Incentive (RHI) is a UK Government scheme set up to encourage uptake of renewable heat technologies among householders, communities and businesses through the provision of financial incentives.

The UK Government expects the RHI to make a significant contribution towards their 2020 ambition of having 12 per cent of heating coming from renewable sources. The Renewable Heat Incentive is the first of its kind in the world.

What Could I Earn Using RHI?

RHI cash payments are made quarterly over seven years. The amount you receive will depend on a number of factors – including the technology you install, the latest tariffs available for each technology and – in some cases – metering.

You can estimate how much money you could earn through RHI using the Department of Energy and Climate Change (DECC)’s RHI payment calculator.

Please note there are some elements that could affect RHI payment.
