Heat Pumps – Ideal Renewable Energy Solutions for Devon Homes & Businesses

We carry out FREE surveys and quotations for heat pumps in and around Devon including rural Dartmoor

Heat pumps are a renewable technology.  They convert the suns energy held in the air or ground into hot water to heat your home. This process delivers green, low-cost, energy-saving heating and hot water all year round.

There are two types of Heat Pumps

In off-gas rural areas of  Devon where mains gas is not available for example Dartmoor where your heating is likely to be an oil based system, the government is actively encouraging you to investigate installing a heat pump with a government Renewable Heat Incentive payment as an incentive.

We offer the installation of both types of heat pumps of which have the following advantages:

  • Reduce your heating and hot water fuel bills, especially if you are replacing conventional electric or oil fired heating
  • The government’s Renewable Heat Incentive (RHI) will allow you to generate an income
  • Depending on which fuel you are replacing you will lower your home’s carbon emissions
  • No fuel deliveries needed
  • Heat your home as well as providing your hot water
  • Minimal maintenance is required to keep your heat pumps working efficiently saving you money

What are heat pumps?

Heat pumps are systems that draw energy from the environment and then pump it into your home, office or hot water system. There are various different types of Heat pumps – Water and Ground Sourced and more commonly Air Sourced

Heat pumps have been used on mainland Europe for many years. The government is encouraging the uptake of Heat Pump Technology through its Renewable Heat Incentive (RHI> programme, much like the Solar PV Feed-in-Tariff the RHI will pay for heat generation. Heat pumps are becoming more common in residential and commercial environments because of the huge efficiency gains they give over conventional heating systems.

Beat rising fuel bills – the growing popularity of heat pumps

The reason that heat pumps are growing in popularity is because all our fuel bills are rising and heat pumps are very efficient. It is possible to get as much as 5kW of heat from 1kW of electricity put into the devices. Also all of the heat pumps we install qualify for the Renewable Heat Incentive (RHI) scheme this means you get paid for your hot water generation just like the feed in tariff for solar panels. For more information about the RHI see the Energy Saving Trust website.

The triple dividend of heat pumps

  • Use renewable energy from air (aero-thermal), water (hydro-thermal) and ground (geo-thermal)
  • They lower final and primary energy demand
  • They reduce greenhouse gas (GHG) emissions

This dividend has recently been acknowledged by the European Parliament and Commission. In the Directive on the promotion of the use of energy from renewable sources (2009/28/EC | RES Directive, § 2) energy from air, water and ground is seen as renewable and heat pumps recognised as the technology of choice to make it usable.

How do heat pumps work?

Heat pumps use renewable energy from air, ground and water to generate useful heat for the home and office. They can also use waste energy from industrial processes and exhaust air from buildings. A heat pump consists of a heat source, the heat pump unit and a distribution system to heat/cool the building. A transfer fluid transports the heat from a low-energy source (i.e. air temp) to a higher energy (i.e. hot water) one. Energy – usually electricity – is needed to run the compressor and the pumps. The direction of this cycle can be switched so the same machine can be used for heating and cooling.

The majority of heat pumps are electrically driven with more than 600,000 units sold in Europe (2009). Market penetration is expected to increase and heat pumps are foreseen to be used in more application fields (e.g. sorption technology for free solar cooling or heating of electric cars).

Improve efficiency & lower emissions

State-of-the-art electric heat pumps can reach efficiencies (seasonal performance factor) of three to five meaning one unit of electricity is transformed to three to five units of heat. The efficiency of systems depends on the efficiency of the unit, the quality of installation and the building’s energy demand.

The higher the system’s efficiency – the lower emissions.

This is also largely influenced by the emission value of the electricity mix / fuel used. Consequently, electrically-driven heat pumps will profit from future improvements in efficiency and carbon footprint of the electricity suppliers. Installed and new units benefit from lower final energy demand and lower greenhouse gas emissions. On top, these pumps are emission free at the point of operation.

When using green electricity, biogas, or thermal energy from renewable sources, heat pump systems provide a 100% renewable solution for heating and cooling of buildings. In systems where auxiliary energy is provided from conventional (fossil) sources the share of renewable energy used is calculated as the difference between the total final energy demand and the amount of auxiliary energy input.

The comparison of heat pump systems using air or ground as energy sources in residential buildings with a gas condensing boiler reveals a possible savings of between 20% and 50% in primary energy, 35% and 80% in final energy, and 49% to 67% in GHG emissions. Heat pumps use between 65% and 78% of renewable energy to meet their total final energy demand – see European Heat Pump Association www.ehpa.org.

The dividends are too good to be ignored. With heat pumps, we can reach European and worldwide targets in energy savings, use of renewable and GHG emission reduction – but we must start now. Be part of the growing numbers of people in Devon who want to lower emissions and reduce their energy costs by installing eco friendly heat pumps that use renewable energy to provide efficient heating and supply hot water.
