Questions About Renewable Energy? Get In Touch.

General

What is renewable energy?

Renewable energy is widely regarded as any energy that is derived from resources that are sustainable on a human timescale, such as solar, wind, rain, tides, waves and geothermal heat. However, small scale renewable energy installations use Microgeneration technologies such as Heat Pumps, Biomass and Solar.

Is renewable energy right for me?

In some cases, the figures just do not add up to install a renewable energy system in your property. If this is ever the case, we will refuse to go ahead and let you know the best way to go forward with your project, as we would much rather have no customer rather than an unhappy one.

If renewable energy is so good why doesn't everyone have it?

A vast amount of the general public are still blissfully unaware of the potential benefits of renewable energy. With fossil fuel alternatives being much more widely accessible it is quicker and easier (but not smarter) to go with conventional LPG or Oil boilers.

Ground Source Heat Pumps

Do Ground Source Heat Pumps work?

Despite much speculation since Ground Source Heat Pumps first appeared within the UK market, poorly fitted installations means that a stigma has been built around the viability of Heat Pump technology, but rest assured with Hero Renewables our expertise and experience in the renewables sector guarantees our customers peace of mind.

How much ground work is required?

There are two possible methods to take when installing a Ground Source Heat Pump into your property. The most common method is using horizontal ground loops (slinkies) which are sized in proportion with your heat pump, the pipes are laid 1.2-1.4m into the ground so ground space will be required to use this method. Alternatively it is possible to transfer heat using a borehole, typically around 100m in depth, which is a highly efficient method and requires very little ground space.

How efficient is a Ground Source Heat Pump system?

The majority of our GSHP’s come with inverter driven technology as standard which means only the energy required to meet the actual demand is supplied. Also, for every unit of electricity required to run one of our GSHP’s you get four kWh’s back, making it an incredibly efficient way to heat your home. With the addition of underfloor heating efficiency can be boosted even further.

Are Ground Source Heat Pumps suitable for new builds?

Ground Source Heat Pumps work fantastically with new builds for a variety of reasons. Getting Hero Renewables involved in your project as early as possible is highly recommended. Not only are new builds finished to a high specification perfectly suited for ground source heating, they are also subject to 0% VAT on renewable technologies. With the added efficiency of high insulation, and the opportunity for underfloor heating, we believe every new home should realise the benefits of GSHP’s.

Air Source Heat Pumps

Are Air Source Heat Pumps noisy?

Air source Heat Pumps produce a very subtle humming noise not too different from a conventional fossil fuel boiler. As they will be situated outside it is understandable that you may be worried about disruption to your neighbours. Rest assured that sound checks are a legal requirement when installing an ASHP which eradicates any future complications.

How much ground work is required?

An Air Source Heat Pump (ASHP) is ideal for people who may not have the space for a Ground Source Heat Pump (GSHP). ASHP’s also take less space to install than an oil or LPG tank, especially when no buffer tank is required.

Can an Air Source Heat Pump be installed outside or in a basement?

An ASHP is a much more space efficient way of heating your home when compared to a Ground Source Heat Pump. They are conveniently stored around the exterior of your house or flat, however you will need to make room for a hot water cylinder and buffer tank, which require roughly 1m by 1.5m, although we have been known to fit it in smaller!

Do Air Source Heat Pumps work in the cold?

Our Air Source Heat Pumps work with temperatures as low as -20, but losing efficiency the colder it gets, however you will not notice any changes in your home.

Biomass Boilers

What is Biomass?

Biomass energy refers to all biologically produced matter from living or recently living organisms. Modern day biomass heating usually refers to the burning of Pellets, chips or logs. Biomass boilers are actually very simple systems, and work very similar to that of conventional fossil fuel burning boilers.

Is it a sustainable form of heating?

The burning of biomass fuel is part of a closed carbon cycle. This means that the carbon taken from the atmosphere in order for the trees to go creates a replenishable cycle when the fuel is burnt. All biomass suppliers must be registered to the Biomass Suppliers List (BSL) which ensures sustainability procedures are being followed.

How often do fuel stores need refilling?

At Hero Renewables we design your fuel stores from the ground up. Our bespoke storage design is there to make you life easy, which means refilling should only have to occur 3-4 times a year.

Do I have to load the fuel myself?

This depends on the size of your boiler, for smaller systems we usually recommend a hand fed hopper and larger systems tend to be automatically fed from a pellet store either by a vacuum or an auger.

Where do I buy my fuel?

We will recommend you only purchase your fuel from a local company listed on the Biomass Suppliers List (BSL).

Solar PV

How will the January Feed-In Tariff cuts affect my installation?

The government cuts to the Feed-In Tariff scheme has seen a 64% drop for all new installations. Does this make installing solar panels a worthwhile investment? If you choose Hero Renewables, the answer is still yes. Our award winning solar team specialise in bespoke smart systems incorporating solar battery technologies, which see a return on investment similar to that before the cuts were introduced.

How does the Feed-In Tariff work?

The Feed-in Tariff means you could get paid for all the electricity you generate even if you don’t use it. Any energy you do not use gets sent back to the grid which you also get paid for under the Export Tariff.

Do Solar Panels add value to my property?

Barclays Digital Homes report revealed Solar panels rank highest in desirable technology, with homeowners willing to pay an average of £2000 more for a property equipped with them.

Do Solar Panels need cleaning?

We don’t recommend you wash your system more than once a year, nature will usually take its course and do it for you, however if you are worried there are plenty of professional trained PV cleaners around.

Does my roof need to be south facing?

If you have a south facing roof with an angle of 30º-40º you will be generating the optimum amount of energy possible. This doesn’t mean if your roof isn’t completely south facing it won’t be worthwhile, if you want to find out how feasible your home is for Solar PV, contact us now for a free quotation.

Do I need planning permission?

Typically, planning permission is not needed unless the building is listed, it is in fact possible to install renewable energy on any building, Hero Renewables are with you all the way when it comes to the planning stages.

Solar Thermal

Will my Solar Thermal system still work in the winter?

There are many variables that determine how much energy your panels produce, cloudiness does effect efficiency, but as long as the sun is shining water temperatures will be raised all year round.

Can I use my Solar Thermal system for other purposes e.g. a swimming pool?

Yes! In fact, we recommend solar thermal systems to do just that, they are able to heat the entire pool, which is a very effective way to reduce the running costs.
