Why Heat Pumps?

Installing a heat pump in your property will give you four pounds’ worth of heat for every pound of electricity you invest.

In addition, during the warmer season, a heat pump works as an air-conditioner providing you with year-round comfort.

Because the heat pump does not burn any fossil fuel when producing heat, it produces far less greenhouse gas emissions than a conventional furnace. Furthermore, a heat pump eliminates a potential source of carbon monoxide in your home entirely.

How Heat Pumps Work

A heat pump is an electric device that extracts and transfers heat from one place to another by circulating a substance called a refrigerant. To make cool space cooler and warm space warmer, heat pumps move the heat away from space to make it cooler and move warm air into a space to make it warmer.

Heat Sources

Ground Source Heat Pumps

Ground source heat pumps draw heat from the earth to heat your home. They are a powerful technology used for heating and cooling spaces and they are highly efficient and renewable. Compared to other heating systems they are environmentally friendly and have low maintenance once installed.

Air Source Heat Pumps

During the winter season, air-source heat pumps draw heat from the ambient air and exclude outside heat during the cooling season in summer. An air-source heat pump can provide efficient heating and cooling for your house. An air-source heat pump, when properly installed, can provide one-and-a-half to three times more heat energy to a home than the electrical energy it uses.

Solar Assisted Heat Pumps

In an integrated system, a solar-assisted heat pump (SAHP) combines heat pump and solar thermal technologies. Aluminium panels mounted on an exterior wall or roof usually absorb heat. The future energy savings are greater compared to solar thermal systems which are less efficient during winter months.

Ground Source Heat Pumps

A ground source heat pump, also known as a geothermal heat pump (GHP), is a central system that can both heat and cool spaces by transferring heat from the ground or to the ground.

How Ground Source Heat Pumps Work

Ground source heat pumps (GSHPs) extract heat from the ground using a network of pipes laid underground. The heat extracted is absorbed into a fluid and passed into a heat pump which is then circulated in the home to bring the heat to underfloor heating systems, hot water to boilers, radiators, and so on.

Why Ground Source Heat Pumps?

Ground Source Heat Pumps save Money

Compared to direct electric heating, the running cost for a heat pump is low. And compared to oil boilers and gas boilers, they are cheaper and can save you money.

Ground Source Heat Pumps save Carbon Emissions.

Unlike coal, burning oil, biomass or LPG, a heat pump generates no carbon emissions on-site, and no carbon emissions at all, if they are powered by a renewable source of electricity.

Heat Pumps save Space.

Heat pumps don’t require fuel storage. There is no ignition involved and no possible harmful gas emissions. Also, no flues are necessary. Planning authorities like ground source systems, as they are safe, silent, invisible, low environmental impact heating systems. No planning permission required.

How Much Would a Ground Source Heat Pump Save Me?

Because of its low running costs, heat pumps can result in considerable savings compared to conventional heating systems. For example, compared to a new gas boiler, a ground source heat pump can reduce energy bills by at least 26%.

Depending on which system you want to replace, an average ground source heat pump could save you between £500 and £1,400 per annum.

Air Source Heat Pumps

How an Air-Source Heat Pump Works

Air source heat pumps absorb heat from the outside air, heating the fluid in them. This fluid then passes through a compressor which raises its temperature and transfers its higher temperature heat to the house’s heating and hot water circuits.

How Much Could an Air Source Heat Pump Save Me?

Air source heat pumps offer about £400 in annual savings compared to electric resistance heaters and about £800 in annual savings compared to oil furnaces.

Ground Source and Air Source Heat Pumps Compared

Owing to the fact that heat is transmitted via the ground through water movement, ground source heat pumps are more effective than air-source heat pumps, as water has a greater capacity to retain heat relative to air.

Converting air temperatures can take more energy than converting temperatures at ground level. So ASHPs consume more power than GSHPs.

On the positive side, ASHP systems can cost less upfront and typically provide you with a better return on your investment in more moderate climates. However, when the outdoor temperatures fall, they lose their advantage.

Installing a heat pump with air supply is as simple as hooking up an air conditioner. Your house doesn’t have to fulfil specific standards to apply for a heat pump.  Ground source heat pumps require land excavation around your home, and can only be appropriate if you have enough subsoil and a large enough space in your yard.

Once installed, a ground source heat pump can achieve bigger savings on energy bills, particularly if you are replacing an oil boiler. However, both systems can save you money in most situations.

How Much Can Heat Pumps Save you?

If you have oil-fired heating currently, the Energy Savings Trust says you could save between £475 and £735 a year. If your home has electric heating, the savings are much higher for the whole year ranging from £830 to £1465. Finally, if your home has gas heating, then by having a heat pump installed the savings are between £1315 and £1975 annually.

Renewable Heat is Cheaper than Conventional Fuels

The energy produced by renewables these days is just as affordable as, if not cheaper in some cases than the energy produced by fossil fuels. Any solar panel schemes can also produce electricity at about half the cost of fossil fuels such as coal. That is a lot of potential savings.

How to Make the Most of the Renewable Heat Incentive (RHI)

The Domestic RHI provides financial incentives to domestic property owners who install renewable heating technologies on their premises, such as ground source heat pumps and solar thermal.

The RHI scheme is administered by the energy regulator Ofgem. The application form can be found on their website.

To fill in the domestic RHI application form you will need:

  1. Your Microgeneration Certification Scheme (MCS) open key term certificate number.
  2. Your Energy Performance Certificate open key term number.
  3. Your bank details so Ofgem will be able to pay you.

Make sure the name you have on your bank account is the same as the one you use to fill the application.

The scheme remains open to applications until March 31, 2022, and you can apply through the Ofgem website.

District Heating and Communal Heating

District Heating, also known as heat networks or teleheating, this is a system for the distribution of the heat generated in a centralised location by means of insulated pipes for residential and commercial heating requirements such as space heating and water heating.

Communal Heating supplies heat from a common heat source or boiler to a number of dwellings. It may consist, for example, of a system that heats a block of flats, or of a larger system that heats many buildings. This eliminates the requirement for individual boilers and supply of gas within each home.

What’s the Difference Between District Heating and Communal Heating?

Community heating is a centralised heating system with more than one heat customer providing heat and hot water to one building block. A district heating system, on the other hand, is a large-scale generation of heat distribution, usually found in towns.

Is Communal Heating Right for my Property?

If you have a property of 50 apartments and above, a communal heating network is right for you. In fact, a communal heating system can be used anywhere from a small domestic environment (i.e. a house) to a network of big business premises and the public sector, such as a hospital. Leisure centres, schools, offices, jails, and large residential projects can benefit from a communal heating system, too.

Forward Thinking Heating Solutions with District Heating

District heating is a hot idea whose time has come. It offers cleaner central heating with obvious health and air quality benefits, fuel savings, space savings and less smog. More than 50% of the UK’s actual, usable energy demand comes from building heating and cooling use. Installing district heating in towns and communities helps increase their energy quality, contributing to energy savings and reducing the cost to their residents.

Heat Pump Services and Maintenance

Like your car or a gas boiler, heat pumps need regular service to maintain full economic functionality as well. A neglected heat pump can consume more energy – up to 10-25% more – and is more likely to break down leading to more expensive repairs.

To carry out an annual maintenance inspection and service, we offer a simple yet comprehensive service program whereby we will replace filters, optimise the system to suit individual requirements and prioritise a full safety check.

How to Best Look After Your Heat Pump

  • Snow or ice that accumulates on the heat pump needs to be removed during the winter. If a normal thaw or simple brushing isn’t enough, you’ll want to switch off your unit and let it power down completely.
  • Keep the unit clear of snow, ice, and debris outdoors. This includes the top, sides, bottom and the heat pump around it.
  • Do not pick or knock the ice off the heat pump coils using any sharp objects. This could result in a serious personal injury.
  • Check your air filters on a monthly basis. Based on their condition, clean or replace them.
  • Keep the coils clean on the outside. You can use a heavy-duty degreaser if they get dirty and then just hose them down. Ensure you switch the unit off first.
  • We recommend you have your heat pump inspected at least once a year by a trained service technician.
