Heat Pumps

How do Heat Pumps Work

Heat Pumps produce heat for space heating or hot water by using electrical energy to pump and compress a gas with a low boiling point. A thermodynamic principle which states that when a gas is compressed and pressurised its temperature rises causing heat energy within the gas to increase. Heat from the compressed gas is then transferred into your building via a heat exchanger which transfers usable heat into your radiators or domestic hot water tank.

Types of Heat Pumps

There are 2 different types of heat pumps and difference between them is where they get their initial heat source from. Air Source Heat Pumps (ASHP) collect heat from the air whilst Ground Source Heat Pumps (GSHP) collect heat from the constant and ambient heat stored underground which is typically between 10-12°C. GSHP as a result of the higher incoming heat source are around 25% more efficient but do have considerably greater installation costs.

Common Questions and Answers about Heat Pumps

How much money can I save with Renewable Energy2024-03-06T11:37:58+00:00

How much money can I save with Renewable Energy?

There are many factors to consider when switching to renewables. For all of our customers we look for the system which delivers the best return on investment in the quickest time and also offsets the largest amount of carbon. Depending on whether you are looking to install solar panels, energy saving technologies or change to a Heat Pump, the following is a non-exhaustive list of considerations.

  • Solar panels can save you up to 50% off your energy bills if you consume the electricity whilst it is being produced during the day.
  • Installing a Battery Energy Storage System (BESS) can increase your saving by up to 80%
  • A Heat Pump will significantly increase your electricity consumption but eliminate your gas/oil consumption.
  • The cost of gas is considerably cheaper than electricity, but this is predicted to change over the coming years as gas becomes more and more scarce. For example, currently, gas is priced at 0.07p p/kWh whilst electricity costs around 0.27p p/kWh. Using these prices, this means that running a Heat Pump will be more expensive than a traditional gas boiler to run but the homeowner will have no gas bill and a drastically reduced carbon foot print.

How do I know if my home is suitable for a heat pump?2024-03-05T13:45:58+00:00

Heat Pumps may not be suitable for every home as even though they are extremely efficient they produce heat at a lower temperature compared to oil and gas. Heat pumps work most efficiently at a temperature of around 45°C and to heat your home via your radiators at this temperature a few calculations are required in order to determine your properties suitability and the potential size of heat pump. At Landsmart we can produce for you a full suitability report after carrying a Heat Loss Survey.

What Are Energy Assessments For?2024-03-07T16:42:23+00:00
What Are Energy Assessments For?

They are designed to lower increasingly expensive energy costs and move you towards a sustainable future. Business energy assessments are extremely important and, for some companies, a legal requirement.

Energy Performance Certificate (EPC)

An Energy Performance Certificate (EPC) will tell you how energy efficient your home or business premises is: its level of carbon emissions and also how expensive it is to heat and light.  EPCs are useful to identify ways in which to improve energy efficiency and how to save money on energy bills.

The easiest thing to do is get in contact with Landsmart and ask us to conduct a Free Energy Assessment.

How do Air Source Heat Pumps Work?

An air-source heat pump takes heat from the air and boosts it to a higher temperature. There are two main types of air-source heat pumps; air-to-water and air-to-air.

  • Air-to-water heat pumps take heat from the outside air and feed it into your wet central heating system (similar to existing gas central heating). As the heat produced is cooler than that from a conventional furnace or boiler, you may need to install larger radiators or underfloor heating in your home to make the most of it. Air-to-water heat pumps may be best suited to new-build properties or those that are energy efficient.
  • Air-to-air heat pumps take heat from the outside air and feed it into your home through fans. This type of system can be used for heating but can’t produce hot water.

How do Ground Source Heat Pumps Work2024-03-06T09:07:13+00:00

How do Ground Source Heat Pumps Work?

A ground-source heat pump system harnesses natural heat from underground by pumping liquid through it in pipes. The heat pump then increases the temperature and the heat is used to provide heating or hot water.

It performs the same role as a furnace or boiler in a central heating system but uses ambient heat from the ground rather than burning fuel to generate heat.

Ground-source heat pump systems are made up of a ground loop (a network of water pipes buried underground; the larger your home and heating needs, the larger the loop) and a heat pump at ground level.

A mixture of water and anti-freeze is pumped around the ground loop and absorbs the naturally occurring heat stored in the ground. The water mixture is compressed and goes through a heat exchanger, which extracts the heat and transfers it to the heat pump. The heat is then transferred to your home heating system.

This heat can then be used in radiators, for hot water or in an underfloor heating system.
