Heat Pumps Frequently Asked Questions

Your fridge uses the same basic heat pump technology to remove the heat from the food inside the ‘box’, ejecting it to the outside and keeping the food cold.

A heat pump reverses this process and extracts heat energy from the outside air, ground or water and moves that heat into your home (hence ground source or air source heat pumps).

Using the same ‘vapour compression cycle’ as your fridge to produce heat, the heat pump can take a few degrees of outside heat and upgrade it to provide all the heating and hot water you need.

An air source heat pump is essentially a ‘box’ that sits outside your home and uses an ultra-quiet fan to draw air through refrigerant piping, where the heat energy is harvested from the air.

The heat pump runs on electricity and will ‘convert’ each kilowatt of electrical energy into 2, 3, 4 or more kilowatts of heat energy. This ‘free’ energy taken from the air is replaced each day by the sun even on cold days and is therefore cleaner, renewable energy.

This depends on what system of heating you currently use as efficiencies vary, but even with a Natural gas boiler, you are likely to make significant savings.  For Oil, LPG or Electric heating the savings could be even greater.

There are a number of factors that will affect this but for a straight forward install, this could be as little as two days.

For a refurbishment, it depends whether your radiators also need upgrading, whether your water cylinder needs re-siting, where the Heat pump box will be fitted, Insulation requirements etc.

We use technology specifically designed for the UK market and we will only install a solution suited to the individual requirements of your property.

The system is capable of ‘pulling’ any latent heat in the air down to a possible -20°C. Therefore, even if it is snowing outside, you will be warm in your home.

Under new government legislation applicable since March 2022, if we supply and install a system which operates as a heat pump to your home, you pay 0% VAT.

Air conditioning Frequently Asked Questions

A simple principle developed to perfection, air conditioning works like your refrigerator which removes heat continuously from the cabinet and discharges it into the kitchen. You can feel this free heat by touching the coil on the back of your refrigerator.

On warm days, the air conditioning unit extracts heat from the warm air in your home and pumps it outside – and your home or office stays comfortable and cool.

In most circumstances, a single or twin split application can be installed in one day, with minimum disruption.

The benefits of air conditioning are to give a comfortable cooler environment in the warmer months.

The units are exceptionally quiet and ideal if you want climate control in your bedroom for example. An ultra low-noise night time setting can usually be switched on using the remote controller.

A yearly service will ensure that it performs at peak efficiency, it will also save you money on your energy bills.

A properly maintained system also lasts longer. During a preventive maintenance, certain parts that can cause trouble when they are dirty are cleaned to keep the system running smoothly and efficiently.

A maintenance service also includes inspection of your system. So, any problems can be discovered before serious damage occurs and before you find yourself without air conditioning in the middle of summer when you need it the most.

Boiler Upgrade Scheme (BUS) How it works

The government will provide grants to encourage property owners to install low carbon heating systems such as heat pumps, through the Boiler Upgrade Scheme (BUS). These grants will help property owners overcome the upfront cost of low carbon heating technologies.

The scheme will be open to domestic and small non-domestic properties in England and Wales. It will run from 2022 to 2025.

23 May 2022 – The scheme opens for grant applications and payments.

You’ll be able to get:

  • £5,000 off the cost and installation of an air source heat pump

You may be eligible if you:

  • live in England or Wales
  • own your property (whether this is a home or a small non-domestic property)

The property will need to have:

  • an installation capacity up to 45kWth (this covers most homes)
  • a valid Energy Performance Certificate (EPC) with no outstanding recommendations for loft or cavity wall insulation

Solar Thermal, How it works

Solar thermal converts sunlight into heat for hot water, while solar PV panels convert this same energy into electricity. A solar thermal panel is around 80% efficient, compared to approximately 20% for solar PV, meaning you’ll likely need a lot less of them on the roof.

Solar thermal systems must be serviced annually to avoid inefficiency or breakdowns. The glycol fluid should be topped up every tear to maintain the freezing point of the heat transfer fluid (typically minus 15 to minus 25 degrees). The pump must also be checked regularly to protect its warranty and it’s efficient working.

The benefits of air conditioning are to give a comfortable cooler environment in the warmer months.

Solar PV is based on the photovoltaic effect, by which a photon (the basic unit of light) impacting a surface made of a special material generates the release of an electron. Solar thermal, on the other hand, uses sunlight to heat a fluid (usually called Glycol).

Solar Panels work well on any roof facing a Southerly direction ie South, South East or South West. Although your Solar Panels will perform better and produce more electricity if they are South facing, they will still perform at 86% efficiency (compared to South facing) either facing due East or West.

Generally, an 8-panel Solar PV system would be one of the smallest we would recommend and this could easily fit on the roof of an average 3-bed property. 

No, Solar Panels work in all daylight conditions and actually work at their peak efficiency at 10ºc. In fact, if it gets too hot they start to become inefficient.

Solar PV systems have no moving parts apart from the inverter and as such have very long life spans. The inverter should last for over 10 years and may cost up to £1,000 to replace. You should expect the panels to last for at least 25 years.

Most domestic Solar Panel installations take no more than a day with minimum disruption. Typically, the scaffolding will be erected a few days before the Solar PV installation team arrive. We will then mount the panels on the roof and install the inverter, finally carrying out the internal wiring to complete your system.

Solar panels are generally self-cleaning if positioned at an angle of over 15 degrees. However, it is advised to visually inspect them annually and rinse if necessary. 

It is recommended that your Solar Panels are checked and serviced every 2 years. We offer a standard service and maintenance package.

It’s highly unlikely, when we install the Solar PV panels we make sure they are securely attached to the fabric of the building using a roof hook and rail system. Our panels are always mounted at least 30cm in from the edge of the roof to prevent excessive wind loading. 

The electricity produced by your Solar Panels is converted from DC (direct current) by the inverter to AC (alternating current), which your home is run on. The electricity is then taken from the inverter via an AC cable to your distribution board, where it is used to power the circuits in your home.

Battery Storage Frequently Asked Questions

In light of recent world affairs we need a secure, reliable and balanced electricity supply, 24 hours a day.

We also need to make more use of renewable energy resources, to reduce our reliance on non-renewable fossil fuels such as oil and gas that are often imported.

Unfortunately, we have a limited daily window of daylight to harness Solar energy. The solution to this problem lies in battery storage. By storing the energy generated from solar using batteries, we can have a power supply that is available, all day everyday: – without costing the Earth.

 battery System is the answer to reduced electrical costs and in the event of a power cut, the energy storage system will restore power to your home.

Battery storage will complement your solar PV system by storing excess solar energy in the day, instead the excess free energy that was stored during the day can be used in the evening to power your home – at no additional cost.

Our design team will work with you, to establish the best location for a battery storage system in your home. You will be surprised how compact and versatile the addition can be.
