Heat Pump Green Energy Guidelines

Heat pumps take heat from the ground, water or air and use that for space heating and heating up water as well. Where a fridge works by taking the heat from your food and water and removing it, while heat pumps take the heat from the ground itself or water and air and pump it into your home to keep it warm.

Heat pumps don’t always work great in most homes however, since they usually have the best efficiency in insulated buildings and may also be a pretty good choice when you’re building a new home as well. If you hope that using a heat pump will help lower the heating costs of your home, this may not be the case if you plan on replacing a gas boiler, for instance. If you are currently heating your home with electricity, oil or LPG, then you may have greater results overall and an easier time financially.

If you want to install a ground source heat pump, then you have to have plenty of space around your property if you want to achieve that. The space will be necessary for all the pipework that becomes part of it, buried underground to make it happen. It may also be installed using a borehole, but that will cost you more in the end. You will also have to have suitable locations for your drilling machinery if you want to make it happen. Air source heat pumps will end up taking less space, but you still need to have a good bit of distance away from your neighbouring homes and space to do so.

Heat pumps can help heat up water to a lower overall temperature than most traditional boilers, so you would do well to ensure you have a very well insulated home with good floor heating. You can make use of a heat pump with radiators involved, but you will need to use a larger set of them if you want to reach a good level of heating involved. A lot of the older buildings are not really good enough in terms of energy efficiency so they can use floor heating for low temperature radiators.

A traditional boiler with a hot water cylinder will heat up to 60°C or even higher. Using a heat pump will allow you to heat your water easily, but the hotter you make it, the more power it will require to make it happen, so you may want to keep the temperature around 50°C. Boosting it all the way to 60°C once a week will allow you to keep legionella away, which are pathogenic bacteria that happen to grow in such water sources with the right conditions. In many cases heat pumps come with an integrated immersion heater as well.

Since they tend to take up less space, air heat pumps will better serve urban areas and apartments, especially where there is no gas supply at the ready or when they need to replace electric heating. Installing one after a major house clearance initiative will work well, since you will have the most space for it. You also need to consider the chance of hiring a clearance company that works for junk clearance, furniture clearance and more.

Reducing carbon footprint is a mutual responsibility for all of us who inhabit this planet. It is not just your local municipality, state government, a well funded non-profit or national government that can do something significant to help reduce the carbon footprint. You too can do your bit. Read on to find out how!

‘Carbon footprint’ means the amount of carbon dioxide released into the earth’s atmosphere as a result of various activities. Increasing concentrations of this gas are resulting in higher overall temperatures, melting of glaciers and various other changes in the climate that are and will adversely affect the ecology of this planet. Listed below are some meaningful ways YOU as an individual can help reduce carbon footprint:

1. Start with how you use your car

Most people cannot stop using a car altogether but you can reduce your contribution to the carbon footprint by 30% per gallon.

  • Always accelerate slowly and as smoothly as you can.
  • Stay within the speed limit and drive steadily.
  • Always keep your car in good working condition.
  • Replace your filters on time.
  • Or invest in an Electric Car with zero emissions.

That’s all it takes!

2. Change the way you travel

By taking a handful of smart decisions related to travel, you can make a considerable difference to the emission level due to vehicles.

  • Combine errands in one trip instead of many.
  • Use a carpool and save up to 20% per gallon.
  • Once a week, use a cycle to reach office or take out the bike instead of the car. And if your workplace is less than a mile, why not just take a walk!
  • If possible, you can even work from home on some days.

3. Charity begins at home

  • Invest in programmable thermostats in order to control the temperature of your home.
  • Keep your house in prime shape by regularly maintaining the caulking and the insulation.
  • Change your lighting to CFL’s, they cut down the energy bill by two thirds and work for a very long time.
  • At all times, keep your heating and cooling systems in good shape to keep energy loss at the minimum.
  • Teach your children to keep the faucet off while brushing and shaving.
  • When buying appliances, check that it has the Energy Star Label.
  • Replace windows that are losing heat. And start looking for solar energy options for the house.

4. When it’s celebration time

  • Use recycled paper for sending out invites. Or go one step further and cut out paper altogether; go for a virtual set up for invitations.
  • Set a menu having ingredients that can be procured locally and are organic.
  • Set the venue outside in the lap of nature to avoid decorations and other fanfare.
  • Choose a location that involves very little transportation.

5. Reduction at your workplace

  • Shut down your computer and switch off the monitor before you leave for the day.
  • Before printing a document, see if it can be given on a pen drive or better still, can be passed on through an e-mail. If you really need to print, do it on both sides.
  • Carpool to work or walk it if possible.
  • Open your windows to save energy, if you can.
  • Carry your lunch from home or walk to the coffee shop; don’t drive just because it has become a habit.
  • Only switch on lights you need.

The most important thing to remember is – Reuse, reduce, and recycle.

You can do it! Let’s make our planet more beautiful than we our ancestors left it us for.

The Green Deal for Home – Explained

Tags: , ,


Green Deal Plan for Home: Here is the Start to Finish Process

It’s called the Green Deal – a project designed to help you make energy saving improvements at home and also to find the ideal way to make payments for the same. Home improvements for maximum energy conservation generally depend upon the structure of the house. However the main focus of the project should be including solid wall insulation, double glazing, boiler upgrades, and much many other things discussed below.

After many years of talking and planning about the Green Deal, the flagship energy saving scheme designed by the government is finally up and running. The aim of the project is to make every house warmer and much cheaper to run. To achieve this however, people are not required to shell large sums of money upfront. 

The Green Deal project typically comprises of the following stages:

1. Assessment

Assessment involves inspection of your home or office premises by a fully accredited Green Deal Advisors. The respective advisor will perform the following functions:

  • Survey the entire property and come up with EPC (Energy Performance Certificate) in order to ascertain the current energy rating and also to recognize the types of developments which the Green Deal can fund.
  • In case the EPC recognizes any suitable measure fit for attaining Green Deal finance, the Green Deal Assessor will commence a Green Deal Occupancy Assessment and recognize what improvements are going to be cost effective and look out for any scope of cash back or subsidies.
  • Explain in detail the entire payment process
  • Prepare a Green Deal advice report that will outline all your available options
  • Also assist you in selecting a Green Deal Provider
  • Supervise the home improvement installations and sign off as soon as the work is complete.

2. Installation

The Green Deal Advisor will fix up with the Green Deal Provider and appoint a suitable Green Deal Installer for you. The installer will then make the required home improvement jobs – you and the Green Deal Advisor agreed upon. You are required to constantly access the installer to ensure he fulfills all the standards laid down by the Green Deal.

3. Repayment

You are required to pay back the cost of your various home improvement jobs over a period of time by means of electricity bills. Here your electricity supplier is supposed to pass on your payments to the respective Green Deal Provider. It is to be noted that the amount you pay via your electricity bill is not going to be more than you save upon your heating bills. This way you are guaranteed to be in profit from the very first day.

You’ll be required to pay for your home improvement services, but the payment you make will never be considered as your conventional personal loan. Reason – the payment will be attached to your electricity meter and paid back in the form of electricity bill. In case you vacate the property, the charge will be picked up by the new occupant, who will also benefit from the energy-efficient property.

A regular interest will be charged on all payments, but the rate will be fixed. In addition, you will be shown a complete schedule of all the payments before you finally sign up the plan.

Improvements covered by the Green Deal include:

  • Insulation
  • Glazing
  • Heating and hot power
  • Microgeneration

The non-domestic centers would also cover mechanical ventilation, heat recovery measures and lighting.

Incentives to Begin the Green Deal Scheme

Recently, the government launched the Green Deal Cask Back Scheme in an attempt to encourage more homeowners to take up home improvements right in the early days of Green Deal.

According to the scheme, the most eligible candidates will receive cash back guarantee as soon as they get their measures installed. The highest rates will be allotted to the earliest applicants.

The ECO (Energy Company Obligation)

The ECO for the large six energy suppliers comprises of three parts, including:

1. Affordable Warm Obligation

This will provide heating and hot water saving measures, glazing, micro generation technology and insulation to vulnerable and low-income households. There are however complex eligibility criteria for this scheme.

2. Carbon Saving Obligation

CSO is a means to provide funding in order to insulate solid-walled premises including those with tough to treat cavity walls.

3. Carbon Saving Communities Obligation

This will provide glazing and insulation measures to all people comprising of bottom 15% of the most deprived areas in UK.

South West Renewable Energy Installer Launches Fuel Cell Product at The National Renovation Centre


Category: Heat Pumps
Tags: , , ,


ace-oct

Renewable energy company Ace Energy held the official launch of their partnership with BlueGen manufacturers – Ceramic Fuel Cells Ltd during the Mitsubishi Electric Renewables Roadshow.

The event held at the National Renovation Centre on 31st October presented the benefits of combining electricity generating fuel cells with air source heat pumps.

BlueGen is the world’s most efficient, small-scale electricity generator, delivering up to 60 per cent electrical efficiency. BlueGen delivers 13,000 kilowatt-hours of low-emission electricity per year which is the equivalent output of around 12 kWp of solar PV. Being a combined heat and power generator it will also provide 200 litres of domestic hot water per day increasing its efficiencies to 85 per cent. Considering that a power station delivers maximum efficiencies of just 30 per cent BlueGen is a significant development for onsite microgeneration. It has a wide operating range and as it works day and night – through summer and winter – it can be used to balance electricity from intermittent renewable sources such as solar and wind.

Keith Joynes of Ceramic Fuel Cells explained that when installed alongside a heat pump technology like the Mitsubishi Electric’s Ecodan® significant savings can be made on energy bills. Keith told the Renewable Roadshow audience – which ranged from self-builders and green energy consultants to housing association and local authority executives – that together the two technologies can have a significant impact on reducing fuel poverty and carbon emissions. One of the major attractions for the social housing sector is that BlueGen installations and their ongoing maintenance can be fully funded through an ESCO scheme. This means that a residential social landlord can address issues of fuel poverty and pollution without having to meet the costs themselves.

Ace Energy have built a strong working relationship with Mitsubishi Electric since it originally launched Ecodan in the UK seven years ago and are now extending the benefits renewable heating offers by bringing BlueGen to market.

Ace Energy MD Alan Seviour commented:

“We are pleased and proud to be appointed as the regional distributor and installer of BlueGen. This unique technology promises to become a major contributor to the UK energy mix with the capability of providing crucial support of our dwindling electricity supply as aging UK power stations close. We have always been several steps ahead within the energy efficiency marketplace and BlueGen is our latest example of the innovative approach we take in our business. The technology will take an important position within our portfolio of low carbon services and we intend to place it prominently on the green energy map across the areas we cover in the South West of England and the South Wales regions.”

An Ethical Investment for the Winter


Category: Heat Pumps
Tags: , ,


As we warm ourselves in the afterglow of Ethical Investment Week, happy in the knowledge that we are better and more ethical people for our involvement, I came to wondering what kind of ethical investments might be best for the home.

With these in mind I’d like to highlight the current work being one on Heat Pumps. Because it’s an investment for the home, and if you are in the mind of investing ethically, a heat pump would be a pretty good choice.

This is why:

  • There are two sorts of heat pumps; an air pump, and a ground pump. They work like a fridge. Apart from the other way round. They make the ground/air colder and pump that heat into your house. On average they work at an efficiency of 250-300% however, so they’re quite a lot more efficient than a fridge. (That is it puts out 2.5-3 times the amount of energy put in)
  • Common costs for installation are high to start, but they add that value onto the house and save significant amounts of money on oil, electricity and solid heating bills.
  • It doesn’t need to be warm outside to work. Because the surface area covered is large, given that heat is absorbed through coils, the latent heat in the ground is absorbed. You don’t need to have a hot spring in your back garden for it to work.
  • Maintenance costs are pretty low. Most systems come with a three year warranty. A check by a professional every three to five years should be sufficient.
  • Should you produce too much energy for your own use, you can sell it back to the National Grid.

At the very worst, that is the most inefficient working system against the least polluting fossil fuel, gas, the heat pump system saves 400kg of CO2 emissions per year.

So there you have it. My number one recommendation for an ethical home investment; the Heat Pump. Please, please visit the very good energy saving trust website for more information (link below) and see if this is the kind of ethical investment you might consider.

Myself and everyone at Dorset Energized would like to say: Very Happy New Year!

Join the Green Energy Revolution
After all the Christmas festivities, and dare I say with the current economic climate, at this time of year we all need to tighten our belts, keep warm, oh yes, and make those new year resolutions! So here’s a simple idea for you that could snowball into a green energy revolution…

Whether you are an individual, household, business or part of a community, take 1 step TODAY to:

1) invest in renewable energy
2) reduce your energy demand by becoming more energy efficient and sustainable

Like many people, money is very tight for me at the moment and I am not a homeowner myself so cannot invest in most renewable energy technologies, but I do care deeply about the Earth, and all the people and animals who live here, so I want to play my part. Every individual can make a difference. You can choose to ignore the fact that we all need to save energy and invest in renewables, or pretend your actions don’t count, or you can choose to take positive action – however small – and you never know you may even save some money, right now!

That’s why I took my first step and switched my energy supply to Good Energy last August, and they are now offering you £50 off your first bill when you switch just by quoting ‘Dorset Energized’ – find out more here: www.letsgetenergized.co.uk/energy/switch-energy-suppliers

Here’s some more options for keeping warm, and saving energy and money this Winter:

Wood Energy
Why not take advantage of the new year sales to check out your local heat energy showrooms to choose a more energy efficient woodburning stove (often referred to as Biomass Boliers). Wood stoves are becoming an increasingly popular choice not just for providing a focal point to a room, allowing you to gaze into the flames, but also for providing cheap hot water for central heating and domestic hot water for the whole home. Plus don’t miss out on getting £950 back in the form of a voucher when you install a Biomass Boiler, with The Renewable Heat Premium.
For more information go to: www.letsgetenergized.co.uk/energy/wood-energy

Heat Pumps
Take advantage of The Renewable Heat Premium until March 2013, with a money-back scheme to get either a £850 voucher when you install an Air Source Heat Pump, or £1,250 for a Ground Source or Water Source Heat Pump. Heat pumps extract the warmth from solar energy which is stored in the ground, water courses and in the air. The systems use electricity to drive a pump which extracts the warmth and upgrades it into useful heat. Fridges are heat pumps and work by the same principal but in reverse, moving heat from inside the fridge to outside, thus cooling the inside.
For more information go to: www.letsgetenergized.co.uk/energy/heat-pumps

Combined Heat & Power
Combined Heat and Power (CHP) is a technology that can replace your standard boiler for your heating system, but also integrates the production of electricity, in one single, highly efficient process making it a low carbon technology. A domestic CHP unit can reduce yearly fuel bills by up to £600 and cut household carbon emissions by up to 40%.
For more information go to: www.letsgetenergized.co.uk/energy/combined-heat-power

Our Hopes for 2013
In 2013 we hope to develop the Dorset Energized website and inspire even more people to connect with renewable energy and reduce their energy demand. We want to recommend even more friendly and trusted local experts in renewable energy. And we want to bring you even more fantastic energy and money saving offers to help you take the next step to becoming part of the green energy revolution!

We also want this to be YOUR website – so please do send us your comments for taking positive action on energy via our blog, and we want to hear YOUR stories on your experiences with renewable energy, saving energy, and sustainable living – to help inspire others.

So here’s to a fabulous 2013 and the green energy revolution!

Cornish Manufacturer Launches Pixie Heat Pump


Category: Heat Pumps, Renewable Heat Energy
Tags: , , , , ,


Cornwall-based Kensa engineering, has launched the smallest ground source heat pump on the market, designed to provide space heating and domestic hot water for flats and small dwellings.

The Shoebox Heat Pump is small enough to fit inside a kitchen cabinet! Like all ground source heat pumps it is ideal for new builds, but it can also be retrofitted to properties that have suitably sized outside space, such as a car park, to contain the boreholes for the heat-collecting slinky pipes.

The system is certified under the Microgeneration Certification Scheme (MCS) and is eligible for funding under the commercial Renewable Heat Incentive (RHI) because it qualifies as a district heating system. The marketing executive at Kensa Heat Pumps has been reported as saying that the approximate cost per unit is around £4000, including the borehole and other costs, and that it would typically pay for itself over the lifetime of the RHI.
