Often customers are faced with a
conundrum. They don’t know
whether to stick with their old
ineffi cient oil powered boiler or,
replace it with renewable heat
pump technology.
Those with a boiler over 10 years old will
know that they face expensive repair bills
which is why they should always consider
replacing this with new more effi cient
technology.
The cost of an air source heat pump will vary
based upon the size of unit required and its
functionality. A typical 5kW domestic system,
suitable for a well insulated detached property,
costs in the range of £4,000 to £5,000 installed
(excluding VAT).
However, you may be eligible for a grant from
your Local Authority for installing air source heat
pump technology into your home/business.
To encourage the use of this technology,
the Government award grants through its
Microgeneration Certifi cate Scheme (MCS).
In terms of running costs, you know that air
source heat pumps generate 3 times the units of
heat for electricity used to power them. If you
translate this into monetary savings, it becomes
increasingly clear that they can save you money
on your heating bills.
It has been a busy few months in
the Renewable Heating World and
in this edition of the newsletter,
we’ve featured a number of recent
projects as well as (hopefully)
answer a number of questions that
you have asked us.
Issues and questions arising this quarter
include:
“How much am I going to save on myrunning costs by changing to a renewableair source heat pump?”
“How proven is this technology?”
“My oil system is costing far too much,is this likely to continue rising?”

Also, don’t forget that every year
the cost of conventional fuel rises,
the more cost effi cient an air source
heat pump becomes.
Ask ACS Renewable Solutions if you require
a specifi c calculation of how much money
you can save annually on your heating bills.

Mr & Mrs Burrows of Oxfordshire, were initially
reluctant to dispense with their two-year-
old condensing oil boiler. However with the
continuing rise in oil prices and the quantity of oil
they were using to get through a normal Winter,
they contacted us in Autumn 2009.
Following a survey, our recommendations were
to replace the oil-boiler with an air source heat
pump.
Through their own the research the customer
knew about the Low Carbon Building grant of
£900 and the Renewable Heating Incentive, a
payments scheme similar to the solar feed in tariff
which began in April 2010.
Taking these additional incentives into account
and realisation of the money they would save,
they made the decision to
switch from the oil-boiler to
an air source heat pump.
ACS Renewable installed a
Mitsubishi Ecodan 8.5 kW system.
Following our recommendations, they chose a
Mitsubishi Ecodan 8.5 kW system and it was also
decided to replace the hot water cylinder housed
in the airing cupboard for a more effi cient one.
A total of nine radiators were already installed
into various rooms throughout the house. These
were only a few years old and all quite large
in size ensuring their effi ciency and deemed
worthwhile to keep them.
We installed the new system in two days
disposing of the old boiler and oil tank and post
installation the customer has since reported
making a signifi cant saving in their fi rst Winter
quarter from November to January 2010.
Previously oil was costing the Burrows £350 per

THE RISE OF OIL PRICESIf you are reliant on oil to power your heating
you will be a keen follower of the fl uctuations in
the price of oil and how it will impact on your
pocket.
Nobody can give you an accurate prediction of
what the oil market will do next but, we can
offer you a simple view of what impacts on the
market for oil and therefore you can make your
own valued judgement on where the price of
oil could go in the next two years.
Key factors that have impacted on the price of
crude oil in the last two years include:
Economic Pressures
A combination of global recession and rising
International debt levels have kept the price of oil
low since the peak of over $147 per barrel in June
2008. However, the greater the pace of economic
recovery, the greater the likelihood that the price of
oil will increase.
Demand
It is obvious that the demand from faster-growing
economies of South East Asia have led to a price
increase in oil. Some experts believe the consumption
of easily extractable crude oil has peaked which would
also lead to an increase the price of oil as production
costs then rise.
Natural events and confl icts
Natural Disasters and Confl icts in oil producing areas
also exert pressures on the price of oil.
The US Dollar
As oil prices are set in dollars, the higher the price of
the dollar against the pound, the more expensive the
cost of oil. This is what is happening at the moment
with the dollar starting to rise against pound sterling.
Ultimately we believe there is enough evidence
to suggest that oil prices will rise between
now and 2012 which undoubtedly means that
people who rely upon oil to heat their homes
will see their bills rise also.
If you think the time is now right to move
away from oil powered heating to save you
money, call us today and we can help you start
to quantify what you could save using cleaner,
more cost effective renewable energy to heat
your home.

HOW PROVENIS THIS TECHNOLOGY?A question we are asked all of the time!
The answer is that air source heat pump
technology is now common across Europe,
where many countries have been installing the
technology into their homes for a longer time
and in far greater numbers than the UK.
What really triggered interest in air source heat
pumps was the energy crisis in the 1970’s,
when the colder climates of continental Europe
demanded alternative sources of domestic heating.
Nowadays, the technology has been refi ned and
tested to a point that they are now commonplace
across homes in France, Germany and Sweden
as the table opposite indicates.
Estimated air source heat pump installations 2006-2008
2006 2007 2008
Sweden 70,856 57,000 56,500
Germany 40,000 45,000 56,000
France 53,000 70,000 150,000
With a track record for enhanced effi ciency,
colder Winters and a rise in domestic fossil
fuel prices, it is no surprise there is such a massive
increase in demand for air source heat pumps
now across the UK.

There are heat pumps installed inside the
Arctic Circle.

TIME FOR A CHANGE
Continued from front...
winter quarter.
In their fi rst quarter using the air
source heat pump the cost of
heating and hot water had fallen
to approximately £185, a saving of
£165 in it’s just three months.
In addition to the savings, Mr & Mrs Burrows enjoy
very effi cient heating and hot water throughout
the year.
With last Winter’s common delays in oil
deliveries no longer an issue, and the prospect
of more income to come from the Renewable
Heating Incentives - due to start in April 2011 -
the change from oil-boiler to air source heating is
increasingly looking like a wise decision.
Mr James’ heating system had served him well
for more than 20 years; however oil and fumes
began leaking from the system. With spare parts
no longer available he decided it was time for a
change.
His East Sussex home is not on the gas grid and
built in a traditional cavity block and brick with
cavity wall insulation.
With ample loft insulation
and all the windows double-
glazed, it was a relatively
simple choice for Mr James -
a Mitsubishi Electric Ecodan
system, which produces
all his hot water and central heating needs,
whilst avoiding retrofi t work that would disrupt
decoration, furnishings, carpets and fl oorboards.
Most of the radiators installed in his home were
deemed to be large enough to cope with the
lower water temperature required by air source
heat pumps, making sure the house is warm
enough and costing less to run. An air to water
heat pump stores the hot water using a typical
copper cylinder.
To supply all of the hot water for Mr James’ home
including two-bathroom towel rails, a 210-litre
twin coil Cylinder was installed with the system
connected using a 24-hour 7-day programmer,
and room stat controlling the towel rails.
Mr James and his family now enjoy constant
heating and hot water. In one smooth operation
they managed to get rid of his old oil-boiler, the
storage tank and connecting pipes, whilst making
savings from reduced energy costs.
