New Energy Sources

Whether we like it or not, the world is changing around us and in terms of energy usage will be very different in the not so distant future.
To prepare ourselves for this different future, we have to think ahead; today, everyone is focusing on the recession and how to bail out bankrupt countries, and paying little, if any, attention to the energy crisis which is coming towards us like the proverbial train.
Although we cannot do much to sort out the areas such as the economy or the European Union and the like, we can prepare our homes and businesses (such that they will not be significantly affected by energy shortages) and save a lot of money on electricity and heating bills.

This website has been created to explain the technologies behind renewable energy in plain English and to help you to decide which if you think any, is best for you.
However, it is not only about technology but also about the reasons why we are searching for alternative energy sources.
You can find here, not only widely supported theories about global warming, but also unpopular ones.
We hope you will find this website useful and interesting and if you decide to turn your house “green”, do not hesitate to contact us.

In this section we will explain how the equipment and technology behind renewables works.
For many people who are not familiar with mechanical engineering, physics and advanced technology it can be quite difficult to understand how an air source heat pump works., For example, how can an air to water pump produce enough energy to heat up an entire house and hot water system by using ambient air.
This makes the decision to install such a system in your house even harder.
We hope this website will help you to understand how such a system works and, in so doing, become more confident to consider installing a renewable energy system in your house or business.

How does it work?

• Ground Source Heat Pumps
• Air to Water Heat Pumps
• Air to Air Heat Pumps

To understand how a heat pump works, let's start with something we all are familiar with, a fridge. This very common device can be found in every household and we currently can't live without it. Most of you may be very surprised when I tell you that a fridge has a lot more in common with a Heat Pump than a gas boiler. Why; let's have a look at the principle function of each system:

A fridge’s primary function is to keep the internal compartment cooler than the surrounding environment by removing any excess heat from this compartment to make sure our food is safe.

Now let's have a look at a Heat Pump’s primary functions. Every Heat Pump has the same function whether it is a ground source, air to water or air to air, to produce heat for a house central heating and hot water system. How can they be similar then? One is used to cool and the other is used to heat.

A Heat Pump produces heat by extracting it from the ground or air using something called a collector. Collectors are different for each type of Heat Pump, gathering useful heat and sending it to a Heat Pump which in turn transfers it to your central heating or hot water system.

The Heat Pump is effectively a fridge in reverse. It is keeping the internal compartment (your house) warm by extracting heat from surrounding environment (ground or air).

At this point, I will get a bit more technical to explain the laws of physics which allow us to do this and I will explain the functions of a Heat Pump components.



• Refrigerant:
Wikipedia states: A refrigerant is a substance used in a heat cycle usually including, for enhanced efficiency, a reversible phase change from a liquid to a gas. The ideal refrigerant has favourable thermodynamic properties, is unreactive chemically, and safe. The desired thermodynamic properties are a boiling point somewhat below the target temperature, a high heat of vaporization, a moderate density in liquid form, a relatively high density in gaseous form, and a high critical temperature. Since boiling point and gas density are affected by pressure, refrigerants may be made more suitable for a particular application by choice of operating pressure.

• Refrigerant circuit:
It is this part of a Heat Pump which contain refrigerant and comprises a compressor, condenser, capillary tube (or expansion valve), evaporator and copper pipes connecting all component parts to form a circuit. This is not a full list but it is sufficient to understand the way Heat Pumps work.

• compressor:
The most important part of the circuit. It's the heart of every Heat Pump and every refrigeration appliance. The compressor is responsible for compressing the refrigerant which causes it to become hotter. Before the refrigerant reaches the compressor, it must be in gas state (vapour) otherwise it can't be compressed. Once the refrigerant is compressed, it is then pumped into the condenser.

• Condenser:
It is responsible for condensing the refrigerant. Condensing means changing state from vapour to liquid. You can observe condensation on your windows very often when the outside temperature is lower than inside. The Condenser works in exactly the same way; it removes heat from the refrigerant giving rise to this transformation. The heat is then transferred into the central heating or hot water system and the refrigerant is travels to the Capillary Tube.

• Capillary Tube:
This Device is positioned in between the Condenser and the Evaporator. Its main function is to control refrigerant flow to the Evaporator.

• Evaporator:
The extracted Heat from the collector is transferred into the refrigerant, which in turn starts to boil and changes to vapour. The most important function of the Evaporator is to ensure the refrigerant is in a gas state before reaching the Compressor where the whole process starts again.

How it works?

Ground Source Heat Pump (for simplicity let's call it GSHP) is capable of producing enough energy to heat a house and hot water system by using a refrigerant circuit. In most cases it guarantees savings on your heating bills.

This particular type of a heat pump is collecting heat stored in the ground and in so doing, it is utilising an array of pipes buried in the ground.These pipes are the collector. There are a few different types of collectors. The most common types are the trench and the bore hole. The Collector is transferring heat to your heat pump where the refrigerant is increasing your central heating and hot water temperature.

This is how it works;

Air to Water Heat Pump (for simplicity let's call it AWHP) is capable of producing enough energy to heat a house and hot water by using refrigerant circuit. In most cases it guarantees savings on your heating bills.

This particular type of a heat pump is extracting heat from the ambient air and in so doing it is utilising a fan driven by electric motor. This fan is ensuring sufficient air flow to your heat pump where the refrigerant circuit is increasing your central heating and hot water temperature.

How to capture solar energy?
The Sun is the base of the whole life on Planet Earth. Without it nothing can survive.
It poseses unimaginable quantities of energy, and it accounts for about 99.86% of the total mass of the Solar System.
It keeps us warm and allow food production. By photosynthesis green plants convert solar energy into chemical energy, which produces food, wood and the biomass from which fossil fuels are derived.
No wonder we humans decided to use solar energy to produce electricity and to heat our houses.
Below you can find most common ways of harvesting solar energy.

• Solar Hot Water
• Solar Central Heating
• Photovoltaic

How The Sun can give you up to 60% of hot water for free?
This particular system is catching the solar energy using solar collectors.
The most popular type of solar collectors are flat solar panels which consists well insulated box with set of copper pipes within at the top it is closed with specially prepared glass ensuring minimum light reflection.

Alternatively evacuated tubes can be used serving the same purpose of catching sun energy. Evacuated tubes are slightly more efficient but also a lot more vulnerable for damage by falling slates or a tree branches.

Every solar collector transfers accumulated heat into hot water system using the pumping station. This station is using the set of sensors places in the solar panel and in the hot water storage tank. These sensors control heat transfer from collector to the hot water storage tank. Solar pumping station also comprise circulating pump which ensures sufficient flow of heated fluid from the collector. It is very important to balance the pumping station correctly to ensure flow rate is correct. If system is not balanced correctly it will never produce maximum efficiency and may even get damaged.
The solar collector is filled with a special mix of glycol and water. Glycol is used to prevent fluid freezing in winter.

Well designed solar hot water system should include form of the backup in case of insufficient sun energy or high hot water damand.
The most efficient backup is gas fired boiler so if you have one already in your house all what you need is solar kit. Other form of backup can be immersion heater built in you hot water cylinder, oil fired boiler, etc.
Solar hot water system is compatible with vented and un-vented installations and in most cases can be added into existing system without significant alterations.
The most energy can be collected from South faced part of the roof.

After installation the only cost to produce hot water from solar panels is electricity to run an economical low power pump built in the solar pumping station.

How the Sun can reduce your heating bills?
As you can see from the drawing below this system is very similar to the solar hot water system. It uses the same type of collectors but it ususally needs more of them.

In most cases this system is designed as solar central heating combined with solar hot water.
The pumping station works on the same principals as the solar hot water one but uses additional sensors.

Different type of hot water storage tank should be installed, if this can not be achieved mixing and motorised valves with additional controllers can be used.
It has the same requirements for the backup and system balancing and it uses the same glycol and water mix.
In most cases it requires alterations to existing system but once in place it can provide significant savings.
