Solar Water Heating Costs

Questioning solar

One of the biggest considerations homeowners make about solar water heating is the cost. Solar thermal technology can help to reduce your household energy bills and you can even benefit from government's Renewable Heat Incentive (RHI), meaning the installation will pay for itself over time. There is however an initial cost and this can vary depending on a number of factors including:

  • The size of collector/panel you have fitted
  • The type of collector/panel you choose
  • The cost of adapting your current system to solar water heating
  • The hot water cylinder you choose

Cost of a Typical Solar Thermal System

A typical system will cost between £2500 and £5000, but a big portion of this cost is down to scaffolding and plumbing work. Therefore, it's a good idea to have solar water heating fitted during repair work on your home or integrating it into the system in the construction of a new house.

How Much can you Save With Solar Water Heating?

Savings incurred from having a solar water heating system are fairly moderate. The system will provide you with about a third of your hot water needs so it will reduce you water heating bills by between £65 and £125 per year (depending on the existing system), according to the Energy Saving Trust.

Solar Thermal System Maintenance Costs

Maintenance costs are the only additional fees on top of the installation and system fee itself. Most systems will come with a five to ten year warranty and it's suggested that you have an expert come and look at the solar panels every three to five years to ensure they're working correctly
