Air Source Heat Pumps

Air Source Heat Pumps

Air Source Heat Pumps take in heat from the outside air. This heat can then be used to heat your home.

The benefits of Air Source Heat Pumps

• If the pump replaces your existing heating you may have lower fuel bills.
• potential income through the UK government’s Renewable Heat Incentive (RHI).
• possible lower carbon emissions.

Unlike gas and oil boilers, heat pumps deliver heat at lower temperatures over much longer periods. During the winter the pump might need to be on constantly to heat your home efficiently.  You will also notice that radiators will not feel as hot as they do when you are using a gas or oil boiler.

How do Air Source Heat Pumps work?

Heat from the air is changed at low temperature into a fluid.  The fluid then goes through a compressor where its temperature increases, it transfers its higher temperature heat to the heating and hot water circuits of the house.  There are two types of Air Source Heat Pump systems.

1. Air-to-water
An air-to-water system distributes heat via your wet central heating system.  Heat pumps work much more efficiently at a lower temperature than a standard boiler system would. This makes them more suitable for underfloor heating systems or larger radiators, which give out heat at lower temperatures over longer periods of time.

2. Air-to-air
An air-to-air system produces warm air which is circulated by fans to heat your home. They don’t normally provide hot water as well.

Costs

Installing a typical system will vary depending on different factors.  Running costs will also vary.  Typical cost of a Daikin 8Kw split Altherma heat pump will be between £8,000 and £15,000.

Ground Source Heat Pumps

Ground Source Heat Pumps

Ground Source Heat Pumps use free solar energy stored in the ground to provide heating and hot water.

The benefits of Ground Source Heat Pumps

• Savings on fuel bills can be in the region of 75% compared with traditional heating systems.
• Can provide heating and hot water 365 days a year.
• A typical unit can last up to 25 years.
• Doesn’t require annual maintenance.

How do Ground Source Heat Pumps work?

Heat Pumps remove solar energy stored in either the earth, air of water around your building, compress it to a higher temperature and transfer it into your central heating system and hot water tank. They are also known as geothermal, ground source, earth energy, air source, water source heat pumps.

How much do they cost?

Ground Source Heat Pumps cost a little more than a boiler but the payback period can be as short as 4-5 years and save you up to 75% compared to traditional methods.

Micro CHP

Micro CHP

Micro-CHP or micro combined heat and power is a technology which generates heat and electricity simultaneously, from the same energy source.

The benefits of Micro-CHP

• When the micro-CHP generates heat, the unit also generates electricity.
• Can reduce carbon and therefore good for the environment.
• Servicing costs and maintenance are estimated to be similar to a standard boiler.

How do Micro CHP boilers work?

Domestic Micro-CHP systems are powered by mains gas or LPG. Although gas and LPG are fossil fuels rather than renewable energy sources, Micro CHP is still considered to be a ‘low carbon technology’ because it can be more efficient than just burning a fossil fuel for heat and getting electricity from the grid.

There are three main Micro-CHP technologies (the difference is the way in which they generate electricity).

• Stirling engine Micro-CHP
This technology is new to the market, although the principal of the Stirling engine is well established. The electrical output is small relative to the heat output but this is not necessarily a problem for Micro-CHP.

• Internal combustion engine CHP
This is the most proven technology. These are essentially, diesel engines modified to run on natural gas or heating oil, connected directly to a generator. Heat is taken from the engine’s cooling water and exhaust manifold. The engines can have a higher electrical efficiency than a Stirling engine and are larger. They are not currently available for the normal domestic market.

• Fuel cell CHP technology
This is new to the market. Fuel cells work by taking energy from fuel at a chemical level rather than burning it.

Solar PV

Solar PV

Solar Panels allow you to generate your own electricity using energy from the sun. They don’t need direct sunlight only daylight, so they also work on cloudy days.

By generating your own electricity you could save on your energy bills. Plus you could be paid for every kilowatt hour (kWh) you generate. The rate you will receive depends on the EPC rating your home achieves. In addition to this any electricity you don’t use, will earn you extra income by feeding energy into the Grid.

The benefits of Solar PV

• Help save on your energy bills by not having to buy all your electricity from your supplier.
• Earn money by generating your own electricity through the Government’s Feed-in Tariff.

How Solar PV works

Your Solar PV system will consist of Solar Panels, an inverter and a generation meter. When light hits the cells in your Solar Panels, electrical energy is created. This electricity then flows through a cable and is collected at a central point. The electricity is converted from DC to AC current and is carried on into your household electricity system. The electricity you generate works using your existing circuit to help power household appliances and lighting.

How much does it cost

The cost will vary according to the panel size, the type of PV cells and the surface they’re mounted on. System sizes range from 1.25kWp – 4kWp and we also offer small roof and shading solutions.  Typical costs are anywhere between £4,000 and £20,000 depending on the specification required.

Biomass

Biomass

Biomass systems (also called Wood-fuelled heating systems) burn wood pellets, chips or logs to provide warmth in a single room or to power central heating and hot water boilers.

The benefits of Biomass heating

• Affordable heating fuel – Although the price of wood fuel varies considerably, it is often cheaper than other heating options.

How Biomass works

A Biomass boiler burns logs or pellets to heat a single room – and can provide water heating as well.

Generally, wood pellets or other biomass products are fed into a chamber where the material ignites. A microprocessor then monitors the combustion in the flue gasses as a result adjustments are made automatically to the fuel supply and the air being blown into the combustion chamber.

Hot gases are then passed through a heat exchanger, so that heat is transferred from the gasses to the water used in the central heating system. The hot water is then circulated around a standard central heating system.

How much does it cost?

The cost of Biomass pellet stoves vary depending on your requirements. Automatically fed boilers will be more expensive than a manually fed system.  Typical cost of a Windhager 26Kw manually fed pellet boiler newly installed will be between £15,000 and £30,000 depending on various factors.

Wind Turbines

Wind Turbines

You can generate electricity at home with small-scale wind turbines. Wind turbines use the power of the wind to generate electricity. About 40 per cent of all wind energy in Europe blows over the UK, making it an ideal country for domestic turbines (known as microwind or small-wind turbines). A typical system in a windy area can easily generate more power than your lights and electrical appliances use.

The benefits of wind turbines

• Get paid for what you generate: You can get paid for the electricity you generate even if you use it. What you don’t use, you can export to the local grid – and get paid for that too.

• Cut your electricity bills: Wind is free, so once you’ve paid for the initial installation your electricity costs will be reduced.

• Reduce your carbon footprint: Wind electricity is green, renewable energy and doesn’t release any pollutants.

• Store electricity for a calm day: If your home isn’t connected to the national grid you can store excess electricity and use it when there is no wind.

How do wind turbines work?

Wind turbines use large blades to catch the wind. When the wind blows, the blades are forced round, driving a turbine which generates electricity. The stronger the wind, the more electricity produced.

There are two types of domestic-sized wind turbine:

• Building mounted: these are smaller than mast mounted systems and can be installed on the roof of a home where there is a suitable wind resource. Often these are around 1kW to 2kW in size.

• Pole mounted: these are free standing and are erected in a suitably exposed position, often about 5kW to 6kW.

Costs

The cost of a system will depend on the size and the mounting method. Building-mounted turbines cost less to install than pole-mounted ones, but they tend to be less efficient.
