Renewable Heat

With gas and electricity prices rising, could you cut your bills by installing renewable heat technologies? We can carry out a site survey to help you determine whether renewable heating is right for your home. Making your own energy will reduce your carbon footprint, give you more independence from future fuel price rises and provide revenue from the RHI. Optimised Heating can design and install heat pump, solar thermal and biomass boiler heating systems.

Renewable Heat Incentive

The Renewable Heat Incentive (RHI) is a scheme designed by the government to financially reward people who use renewable energy to heat their homes. It offers regular ‘tariff’ payments to those using certain technologies to heat their homes. RHI payments are meant to help offset the cost of installing and running a renewable heating system.

Solar thermal panels

A solar water heating system, also known as a solar thermal system, heats water with panels fitted to your roof. Installing solar thermal panels will generate free hot water. You can add solar water heating panels to most existing hot water systems, although you’ll usually need to change your existing hot water cylinder for one with a twin coil. It’s difficult to use a solar water-heating system with a combi boiler.

The benefits of solar water heating

  • Hot water throughout the year. The system works all year round, though you’ll need to heat the water further with a boiler or immersion heater during the winter months.
  • Reduced energy bills. Sunlight is free, so once you’ve paid for the initial installation your hot water costs will be reduced.
  • Lower carbon footprint. Solar hot water is a green, renewable heating system and can reduce your carbon dioxide emissions.

Air Source Heat pumps

Unlike other heating systems that burn fuel to create heat, air source heat pumps use naturally occurring warm air to create power and heat your home. It takes heat from the air and boosts it to a higher temperature using a heat pump. You’ll need enough space in your garden for the external condenser unit (comparable in size to an air-conditioning unit).

Advantages of air source heat pumps

  • ASHPs can provide heating and hot water.
  • They require very little maintenance.
  • Some can be used for air conditioning in the summer.
  • You need to use electricity to power the pump which circulates the liquid in the outside loop. But for every unit of electricity used by the pump, you get between two and three units of heat – making this an efficient way to heat a building.
  • Cheaper Economy 7 electricity tariffs can be used to lower the cost of electricity to power the heat pump and special heat pump tariffs may be available from some electricity suppliers.

Biomass Boilers

Wood-fuelled heating systems, also called biomass systems, burn wood pellets, chips or logs to provide warmth in a single room or to power central heating and hot water boilers. A stove burns logs or pellets to heat a single room – and may be fitted with a back boiler to provide water heating as well. A boiler burns logs, pellets or chips, and is connected to a central heating and hot water system. A wood-fuelled biomass boiler could save you up to £990 a year compared to electric heating.

The benefits of biomass heating

  • Affordable heating fuel. Although the price of wood fuel varies considerably, it is often cheaper than other heating options.
  • Financial support. Wood fuel boiler systems could benefit from the Renewable Heat Incentive(RHI)
  • A low-carbon option.
