Ground Source Heating
Ground source heating uses the grounds energy via a network of underground piping.
The energy from the ground transferred through a refrigerant circuit to produce temperatures of up to 65°C which is used to provide you with heating and hot water.
This couldn’t be any better as the energy you are generating is free .
As a home owner all you pay for is the electricity needed to run the unit, guaranteeing you big savings.
So for the best in Market Harborough, Leicestershire and Now!
There are many benefits to switching to Air Source heating supplies. From up to a £400 saving, no extra boiler needed, provides heating and hot water, quiet to operate, low maintenance costs, reliable 5 year warranty, long lifespan, increased property value and lower carbon emissions.
As if that wasn’t enough, Air Source heating will also give you an energy efficiency, £4 of energy out for every£1 you put in…

Costs of installing a typical system range from about £7,000 to £13,000. Running costs for a year, where all hot water and space heating can be provided by the system are likely to be around £650 per year, but will depend on a number of factors – including the size of your home and how well insulated it is.
Savings can be considerable – up to 540kg of CO2 and £160 if you’re replacing an oil-fired central heating system.
To reduce your home’s CO2 emissions further, consider installing solar electricity or some other form of renewable electricity generating system to power the compressor and pump.

Savings above assume ground source heat pump installed in a detached property which provides 100% of space heating and up to 50% of domestic hot water, the additional 50% is met through an electric heater.
Will a ground source heat pump suitable for my home? To tell if a ground source heat pump is right for you, there are a few key questions to consider:
* Is your garden suitable for a ground loop? It doesn’t have to be particularly large, but the ground needs to be suitable for digging a trench or a borehole and accessible to digging machinery.
* Is your home well insulated? Since ground source heat pumps produce a lower temperature heat than traditional boilers, it’s essential that your home is insulated and draught proofed well for the heating system to be effective. It could also make the system cheaper and smaller.
* What fuel will you be replacing? If you’re replacing an electric, oil, Liquid Petroleum Gas (LPG) or coal heating system, a ground source heating system will pay for itself quite quickly. If you’re replacing a new, more efficient heating system, your savings will be smaller.
* What type of heating system do you want? Underfloor heating systems or warm air heating will work much better than radiator-based systems.
* Is the system intended for a new development? Combining the installation with other building work can reduce the cost of installing the system.
Ground source heat pumps use pipes buried in the garden to extract heat from the ground. This is usually used to warm water for radiators or underfloor heating systems. It can also be used to pre-heat water before it goes into a more conventional boiler.

Beneath the surface, the ground stays at a constant temperature, so a ground source heat pump can be used throughout the year – even in the middle of winter.
The main benefits of ground source heat pumps include:
* Reduce your CO2 emissions: on average a ground source heat pump could save around 540kg of carbon dioxide every year when replacing an oil boiler.
* Eliminate your fuel bills: ground source heat pumps run on electricity, so there’s no need to pay for gas, oil or solid fuels to heat your home.
* Cut down on wasted electricity: heating your home with a ground source heat pump is much more efficient than using electric radiators.
At Lewington’s we are often asked what ground source heat pumps are and how they work.
A ground source heat pump circulates a mixture of water and antifreeze around a loop of pipe – called a ground loop – which is buried in the garden. When the liquid travels around the loop it absorbs heat from the ground – used to heat radiators, underfloor heating systems and even hot water.
The length of the ground loop depends on the size of your home and the amount of heat you need – longer loops can draw more heat from the ground.
Normally the loop is laid flat, or coiled in trenches about two metres deep, but if there is not enough space in your garden you can install a vertical loop to a depth of up to 100 metres.
The efficiency of a ground source heat pump is measured by a coefficient of performance (CoP) – the amount of heat it produces compared to the amount of electricity needed to run it. A typical CoP for a ground source heat pump is around 3.2 without any reductions for the type of distribution system.
Ground source heating is becoming an increasingly popular new way to reduce heating costs. Our latest ground source heating installation in Leicestershire involved laying 500M of underground pipe powering a worcester bosch 11 KW Ground source heat pump. Both floors of the new build property are heatded by underfloor heating meaning the customer should get over £4 of energy out of the heat pump for every £1 they put in.
This will represent a significant saving over time. If you are considering building a new property or would like more information of how ground source heating could work for you, do get in touch.
