Green energy/renewables

The Scottish Borders area's green energy experts

John Rae Limited & Update Systems are the North Northumberland and Scottish Borders region's green energy experts. Not only can we advise you about what energy systems will best suit your property and needs, but we can also give you advice on green energy deals and the loan scheme offered by the Scottish government. The loan scheme:  means you can get a loan of up to £10,000 for installing various energy saving measures (for more details go to - www.energysavingtrust.org.uk/heeps-loan-scheme). Call us today to speak to our helpful friendly team and discuss your home's energy needs on 01450 378997.

Ground Source

Ground source heat pumps work by harnessing the heat stored in the ground from the solar radiation emitted by the sun. This can then be used to meet the energy demands of your home's heating and hot water systems. Installing a ground source heat pump involves drilling a borehole or a horizontal trench, and burying a pipe into the ground. The length of the ground loop depends on the area available and your energy requirements. The pipes are usually filled with a mixture of water and antifreeze which is then pumped through the pipe, absorbing the heat from the ground, which is then concentrated and transferred into your home. This is ideal for under floor heating.

Air Source

Air source heat pumps work by converting the energy of the air outside into heat, which can be used in your hot water system for example. Air source heat pumps are considered to be a viable alternative to ground source heat pumps and are ideal for apartments or homes with limited outdoor space, since the only requirement for installation is an outside wall. Like all heat pumps, air source pumps are most effective when supplying low temperature systems such as under floor heating, and since there is no need for groundworks, installation costs are minimal. If you are unsure as to what system will suit your property best, call us today and speak to one of our energy saving experts.

Solar Photovoltaic

 Solar Photovoltaics ( Solar PV) capture the sun's energy using photovoltaic cells. These cells don't require direct sunlight to work and can still generate energy on a cloudy day. The cells convert sunlight into electricity, which can then be used to run household appliances and for lighting. Any energy not used can then be fed back into the grid and the owner of the system is also able to claim a Feed In Tariff which pays them for the energy they produce. 

Solar Thermal

Solar water heating systems use heat energy from the sun to warm hot water to be used in your home. A conventional boiler or immersion heater is used as part of the system and can be used to make the water hotter if needs be and serves to provide hot water when solar energy is unavailable. Solar thermal installations are a perfect addition to any type of existing boiler installation, so if you would like more details on your systems suitability, call us today.

Biomass 

Current biomass technology means a wood pellet boiler can heat an entire home or small commercial building in an environmentally friendly way. These boilers heat water to around 74°C, and a conventional looking thermostat controls the ignition and combustion. Biomass boilers are intended to integrate fully into a normal hot water system and use the same pipes, while the pellets are made using waste from wood processing plants and sawmills.

Renewable Heat Incentive

The RHI (Renewable Heat Incentive) scheme is a government run scheme that is very similar to the Feed In Tarif scheme for solar photovoltaics. Any heat generated by your Solar Thermal, Heat Pump or Biomass system will be metered and a fixed price for each unit generated will be paid to you just as in the FIT scheme. If you would like to know more about how the RHI scheme works, our staff can give you all the advice and information you need.
