Solar

What is a solar PV system?

A solar PV system consists of solar panels that convert sunlight into electricity. This
electricity can be used to power homes, businesses, or other electrical loads.

How do solar PV panels work?

Solar PV panels contain photovoltaic cells that generate direct current (DC)
electricity when exposed to sunlight. This electricity is then converted into alternating
current (AC) by an inverter, making it suitable for use in buildings and the power grid.

What are the benefits of installing a solar PV system?

Installing a solar PV system can lead to reduced electricity bills, decreased reliance
on fossil fuels, lower carbon emissions, and potentially increased property value.
Additionally, solar energy can provide energy independence and resilience during power
outages.

Is my location suitable for a solar PV system?

The suitability of a location for a solar PV system depends on factors such as
available sunlight, shading, roof orientation, and local regulations. Our professional
team can assess your properties viability for solar energy.

What size solar PV system do I need for my home?

The size of a solar PV system needed depends on your energy consumption, available &
roof space. Our team can help you determine the appropriate system size based on
your specific needs.

What maintenance is required for a solar PV system?

Solar PV systems generally require minimal maintenance. Periodic cleaning of the
panels and inspections of the system’s components are typically all that’s needed to
ensure optimal performance

How long do solar PV systems last?

Most solar PV panels are designed to last 25 years or more, and many manufacturers
offer performance warranties that guarantee a certain level of energy production over a
specified period.

Can I store excess solar energy for use during the night or on cloudy days?

Yes, excess solar energy can be stored in batteries for use when sunlight is not
available. This allows for greater energy independence and the ability to use solar power
during non-daylight hours.

Air Source Heat Pumps

What is an air source heat pump?

An air source heat pump works by taking heat from the outside air and transferring it
inside a building to provide heating or hot water


How does an air source heat pump work?

Absorbing Heat from the Outside Air:

  • The ASHP contains a refrigerant that is circulated through a closed loop of coils.
  • The refrigerant absorbs heat from the outside air, even when the air is cold, and
    evaporates into a gas as it absorbs the heat.

Compression and Heat Exchange:

  • The gaseous refrigerant is then compressed by a compressor, which increases its
    temperature.
  • The hot, pressurized gas is then passed through a heat exchanger, where it releases
    its heat to a separate water circuit in the heat pump, which is used to heat the building’s
    interior space or provide hot water.

Releasing Heat Inside the Building:

  • The now-cooled refrigerant condenses back into a liquid as it releases its heat to the
    indoor environment.
  • The heated water is then circulated through the building’s heating system, such as
    underfloor heating, radiators, or a hot water tank, providing warmth to the building.

What are the benefits of using an air source heat pump?

Air source heat pumps are energy-efficient, environmentally friendly, and can provide
both heating. They can also reduce heating costs compared to traditional systems,
especially in moderate climates.

Are air source heat pumps suitable for cold climates?

Yes, modern air source heat pumps are designed to operate effectively in cold
climates. They are specifically engineered to maintain efficiency even in very low
temperatures.

How do air source heat pumps compare to other heating systems?

Air source heat pumps are generally more energy-efficient than traditional heating
systems, such as electric resistance heating or fossil fuel furnaces.

What maintenance do air source heat pumps require?

Air source heat pumps require regular maintenance, including cleaning or replacing
filters, checking and cleaning coils, and ensuring proper airflow. It’s also important to
schedule professional maintenance at least once a year.

Can an air source heat pump be used with existing pipework?

Yes, air source heat pumps can often be integrated with existing pipework. However,
it may need to be upgraded depending on condition/size.

Are air source heat pumps noisy?

While air source heat pumps do make some noise, modern models are designed to
operate quietly. Proper installation and regular maintenance can help minimize any
noise associated with the system.

How long do air source heat pumps typically last?

With proper maintenance, air source heat pumps can last 15-20 years or more.
Regular servicing and upkeep can help ensure the longevity and efficiency of the
system.

Internal Wall Insulation

What is internal wall insulation (IWI)?

Internal wall insulation involves adding insulation to the interior surface of external walls, which can help to improve the thermal performance of a building and reduce heat
loss.

What are the benefits of internal wall insulation?

Internal wall insulation can help to make a home more energy-efficient, reduce heating costs, and improve comfort by reducing heat loss through walls.

Will internal wall insulation reduce the size of the rooms in my home?

Internal wall insulation will reduce the usable floor area of a room by the thickness of the insulation material. However, the benefits of improved thermal performance can outweigh this consideration for many homeowners.

Are there any considerations for electrical outlets and fixtures when installing internal wall insulation?

Yes, when installing internal wall insulation, these may need to be adjusted to accommodate the added thickness of the insulation.

What are the potential energy savings from installing internal wall insulation?

The potential energy savings from internal wall insulation can be significant, leading to lower heating bills and a reduced carbon footprint.

Room in roof insulation involves insulating the space within a loft or attic that has been converted into a living space, typically to improve thermal performance and
energy efficiency.

What are the benefits of room in roof insulation?

Room in roof insulation can help to make the living space more comfortable by reducing heat loss, lowering energy bills, and improving the overall energy efficiency of the property.

Will room in roof insulation affect the headroom and usable space in the
converted loft?

Room in roof insulation may reduce the headroom and usable floor area of the converted loft by the thickness of the insulation material. However, the benefits of
improved thermal performance can outweigh this consideration for many homeowners.

Will room in roof insulation cause condensation or damp issues?

An assessment is carried out on the property before any works commence, as part of this assessment a ventilation strategy is created. This strategy ensures that there is adequate air flow in your property, helping to prevent issues like damp and condensation.

What are the potential energy savings from installing room in roof insulation?

The potential energy savings from room in roof insulation can be significant, leading to lower heating bills and a reduced carbon footprint.

Loft Insulation

What is loft insulation?
